Standalone Mode
TripSaver II Service Center Configuration Software has two operating modes: Standalone (offline) and Connected (online). The software automatically enters the Standalone mode after the software is launched. It starts with S&C default configuration settings.
Users can define their own default settings that the software uses in Standalone mode by selecting the Tools>Options>Standalone option. In Standalone mode, the settings can be configured without being connected to a recloser, saved to a setpoint file for later use, and loaded into a previously saved snapshot file for analysis. Six settings screens are available under this mode. They are: 1) TCC Curve Settings, 2) NR Curve Settings, 3) Sectionalizing Settings, 4) LCD Screen Settings, 5) Communications Settings, and 6) Local Manual Open. See Figure 23.
Note: Validation in Standalone mode will validate for a TripSaver II recloser rated 100 amperes continuous. Validation in Connected mode will validate settings based on the actual continuous current setting of the recloser: 40 A, 100 A, or 200 A.

Figure 23. The Standalone mode menu tree items.

Connected Mode
The software enters the Connected (online) mode when a communications connection is established with a TripSaver II recloser. When connected, the setpoints from the recloser will be placed into the edit buffer, overwriting all previous settings in the buffer. When the present settings in the buffer have not been saved, a prompt to save the settings will open before connecting to the recloser.
Under Connected mode, one can view existing settings, status information, and event logs of the TripSaver II recloser, apply new settings to the control, download a snapshot file, or perform functional tests. Three additional screens are available under this mode. They are: 1) Status, 2) Event Logs, and 3) Functional Test. See Figure 24. And as follows, the 4) R-NR Functions screen, 5) Gateway Drop Open screen, and 6) DNP Remote Drop Open screen, will open if the TripSaver II recloser has the Extended Open Interval option (“-O”). These screens are also available when a snapshot file is open.
The software also allows viewing the data captured in a previously saved snapshot file.

To view a setpoint field that failed the validation rules, expand the description by double-clicking on the red error message and then single- clicking on the name of the field in black color in the Validation Results panel, as indicated in Figure 45 on page 32. The border of the erroneous field will be highlighted in red.
Note: When validating settings in Standalone mode, the service center configuration software will provide accurate validation for settings for a 100-A continuous TripSaver II recloser. When validating settings in Connected mode, the service center configuration software will detect the actual continuous current rating of the TripSaver II recloser (40 A, 100 A, or 200 A) and validate settings accordingly. If a setpoint value entered is out of range, the border of that edit field will be highlighted in red automatically. Any invalid value will be erased from the edit field when navigating to another settings screen.

Figure 45. The border of the erroneous field, highlighted in red.

For validation under the Connected (online) mode, various error messages are also generated if mandatory setpoint fields are not filled in. For validation in the Standalone mode, the software only validates settings that have already been entered.
When the validation is successful, the Validation Results panel will display a message in green at the bottom of the main screen area after the Validate button is clicked. See Figure 46.

Figure 46. The message showing successful validation.

For settings that can be applied but need special attention, the Validation Results panel will display a warning message in black. See Figure 47.

Figure 47. The Validation Warnings message.

Clicking on the Close button closes the Validation Results panel. Click on the Validate button again to bring back the Validation Results panel. Click on the Validate button at any time to re-validate and display remaining errors, if any.

Apply
The Apply function is only available when connected to and communicating with a TripSaver II recloser. To apply newly configured settings to the TripSaver II recloser, select the Data>Apply option from the main menu or click on the Apply button in the quick access toolbar. The software will validate all of the settings first before applying them to the recloser. Previous settings in the TripSaver II recloser will be overwritten and cannot be restored. The warning shown in Figure 48 will be displayed before the process starts. Save previous settings to a setpoint file or to a snapshot file before proceeding.

Figure 48. The overwrite warning before an Apply operation.

NOTICE
DO NOT unplug the USB transceiver or power down the recloser until the Apply process is completed .

The procedure for applying settings has multiple automatic steps and can take a few minutes. The process cannot be cancelled when the process passes the second of those steps. Do not unplug the USB transceiver or power down the recloser until the process is completed. The message shown in Figure 49 will be displayed after settings are successfully applied.

Figure 49. A prompt dialog box showing the settings applied successfully.

Revert
To reset the edit buffer to its original state, select the Data>Revert option from the main menu or click on the Revert button in the toolbar. The “original state” is defined as:

• For Standalone (offline) mode–Default settings the Standalone mode always starts with each time the software is launched
• For Connected (online) mode–Active settings presently residing in the connected TripSaver II recloser
• When a snapshot file is open–Settings saved in the snapshot file

Note 1: Loading a setpoint file does not create a new original state. Note 2: The Revert button does not undo a configuration step. It is not an “undo” button. It also will not undo an Apply command.

Additional Information Bar

At the bottom of the user interface is an information bar containing four pieces of additional recloser-related information. See Figure 53.

Figure 53. The Additional Information bar at the bottom of the screen.

Signal Strength. The Signal Strength icon provides information on the quality of the communication. It uses four different icons to indicate different signal strength levels:

• When there is no active communication:
• When the signal quality is poor (red):
• When the signal quality is acceptable (yellow):
• When the signal quality is good (green):

A numerical representation of the signal strength is also provided in units of dBm. See Figure 53 on page 38. The greater the value (e.g. -69 is better than -87), the better the signal strength. Main Caps Charge. This indicates the state of charge of the main power supply capacitors inside the TripSaver II recloser.
The bar stays mostly unfilled during the configuration process, indicating only a small amount of charge is needed by the control for configuration use. The blue color indicator will start to fill the empty space as the main capacitors’ charge increases, e.g. during functional testing.
The Main Caps Charge indicator is available for the Connected (online) mode or when a snapshot file is open. Connected To (or Snapshot From). “Connected To” is displayed for the Connected (online) mode. It indicates the serial number of the TripSaver II recloser presently connected. See Figure 53 on page 38.
“Snapshot From” is displayed when a snapshot file is open. It indicates the serial number of the TripSaver II recloser from which the snapshot being viewed was saved. See Figure 54.

Figure 54. The “Snapshot From” serial number.

Transceiver ID. This indicates the transceiver ID of the TripSaver II recloser presently connected. It is only available for the Connected (online) mode.
Battery State of Charge. This indicates the state of charge of the rechargeable battery inside a TripSaver II recloser furnished with the Extended Open Interval feature (“-O” option). See Figure 55.

Figure 55. The internal battery state of charge indicator.

The bar will be filled completely blue if the state of charge is full, and the length will recede as the state of charge drops.

Entering Data

Working with Setpoints and Setpoint Files
Setpoints
Setpoints are user-changeable settings entered into the control to configure a TripSaver II recloser. Setpoints are displayed as checkboxes, data-entry fields, and selection menus. The font color of all setpoints is light blue. Complete a setpoint configuration by clicking anywhere outside its editable field. If a setpoint field is grayed out, it is presently unavailable.
Check box: When the mouse cursor is located over a check box, the background color of the check box will change to light blue. Select a check box to enable the feature; deselect a check box to disable the feature. Note: Deselecting a check box will erase all settings under that feature in the edit buffer.
Data-entry field: When the mouse cursor is located over a data-entry field, the border of the field will change to light blue. Click into the data-entry field to enter the setting.
Selection menu: When the mouse cursor is located over a selection menu, the background color of the selection menu will change to light blue. Click on the menu to expand the list of available items. Click on an item in the list to finish the selection. The background color of the selection menu will change to dark blue, and the font color will change to white. Click anywhere outside the menu to complete the configuration.
Setpoints can be saved locally to a setpoint file with the extension .xspt. A previously saved setpoint file can be loaded into the edit buffer to make changes or to apply the settings to a recloser later. Save Setpoints and Load Setpoints functions are available in both the Standalone (offline) and Connected (online) modes, and also when a snapshot file is open.
Typing on the and + keys on the computer keyboard can be used to navigate back and forth through setpoints.

Flyover Text
When the mouse cursor is located over a setpoint, flyover text will appear for seven seconds to describe the setpoint, including the range for numerical setpoints. When the mouse is located over a command button, flyover text will also appear to describe the function of that button. Flyover text is provided to facilitate the data-entry process. An example of flyover text is shown in Figure 56.

Figure 56. Sample flyover text.

Color Change of Setpoints Border
The color of the border of a setpoint field changes according to the following rules:
• At any time if a setpoint field holds a value within the valid range but is different from the “original” state of the field, the border will change to yellowish orange. See Figure 57.

Figure 57. The border in yellowish orange when the value differs from the “original” state.

The “original” state of a setpoint field, again, is defined as:

• For Standalone (offline) mode–This is the default setpoint the Standalone mode always starts with each time the software is launched.
• For Connected (online) mode–This is the active setpoint currently residing in the TripSaver II recloser.
• When a snapshot file is open–This is the setpoint saved in the snapshot file.

 Setpoint changes will not take effect in the connected recloser until they have been validated and applied. When applied, the changes become the new “original” state for the Connected (online) mode, and the yellowish-orange color will disappear.

• When a setpoint field contains a value out of its valid range, the border will change to red. See Figure 58. That indicates an error that needs to be fixed.

Figure 58. The border is red when the value is out of its valid range.

• When the mouse cursor is located over a setpoint, the border will change to light blue. See Figure 59.

Figure 59. The border is light blue when the cursor is over it.

There is one exception. If a data-entry field has a yellow-orange or red border, the border will not change to light blue. Out-of-Range Warning When a value outside of the valid range is typed into a data-entry field, a warning message opens next to the field indicating the correct range and the degree of precision needed. See Figure 60.

Figure 60. The out-of-range warning.

The warning message disappears on the next mouse click. Note: The invalid value will be erased when navigating to another settings screen.

Save Setpoints
A complete or partially completed set of setpoints can be saved, with one exception:
• As stated previously, if the process of selecting a TCC curve has been started, setpoints cannot be saved, and the Save Setpoints button will be grayed out until the curve-selection process is complete.

Working with a Snapshot File
TripSaver II Service Center Configuration Software allows saving a snapshot of all data from the control at a specific instant and viewing it later offline. The snapshot file has file extension .xdss.
Saving a snapshot is available only in the Connected (online) mode. The snapshot saved always has the same version number as the firmware version of the TripSaver II recloser where the snapshot file was generated.
A snapshot file can be opened in the Standalone (offline), the Connected (online) mode, or when another snapshot is already open. Snapshots that have version number 1.8, 1.7, 1.6, 1.5, 1.3 and 1.0 can all be opened and viewed using this configuration software version 1.9. Note: When opening a snapshot file under the Connected (online) mode, the recloser will be disconnected automatically, and no data will be applied to the connected TripSaver II recloser. You can re-connect to the TripSaver II recloser after a snapshot file is open. See the “Connect to Device” section on page 28.
The setpoints in a snapshot file can be edited and, when the editing is completed, it can be saved into a setpoint file.

TCC Settings Screen

TCC Curve Settings–General
The Time-Current Characteristic (TCC) curves for the initial trip operation, optional sequence coordination, and up to three test operations are selected using the TCC Curve Settings screen, which is also the first screen to open when the software is launched. The five trip operations are named: Initial Trip, Sequence Coordination, Test 1, Test 2, and Test 3 respectively. Setting fields for each trip operation are grouped in separate areas identifiable by trip names shown on the left side of each area. See Figure 61.

Figure 61. Setting fields for each trip operation are grouped in separate areas.

The Initial Trip operation is required; if that is the only trip operation selected, the TripSaver II recloser will operate one time and then drop open (i.e., single shot to lockout). One of the available TCC curves listed in Appendix A on page 99 must be selected for the initial trip and for each of the additional tests to be added.

Sequence Coordination
The optional Sequence Coordination feature maintains proper coordination between an upstream TripSaver II Cutout-Mounted Recloser and the downstream recloser when each is set with fast and slow TCC curves. If the downstream recloser operates, the upstream TripSaver II recloser will shift (without operating) from its Initial Trip curve setting to a user-configured (usually slower) Sequence Coordination time-current characteristic curve. The TripSaver II recloser will maintain its Sequence Coordination setting until the Coordination Reset timer elapses.
When the Sequence Coordination TCC is active and the Coordination Reset timer elapses, it will afterwards revert to the Initial Trip TCC settings. More details on the Sequence Coordination feature with examples can be found in S&C Information Bulletin 461-50.
Sequence coordination is enabled by checking the Enable Sequence Coordination check box. Sequence coordination uses the same TCC curves as are available for the Initial Trip and Test 1, 2, and 3 operations. A Coordination Reset Time setting must be entered (Default: 120 seconds). The Coordination Reset Time setting defines how long the recloser will stay in the Sequence Coordination TCC curve before reverting to the Initial Trip TCC curve. The range for the Coordination Reset Time setting is between 0.5 and 1000 seconds. See Figure 62. The Sequence Coordination TCC curve will use the same Open Interval After Trip setting as the Initial Trip TCC curve.

Figure 62. Sequence Coordination.

Add/Remove a Test Operation
Remove a Test Operation. Click on the green Remove Last Test button at the bottom of the screen to remove the last test operation from the test sequence. See Figure 63.

Figure 63. The Remove Last Test button.

Test operations can only be removed sequentially from the bottom up. For example, Test 2 cannot be removed without first removing Test 3. The Test 3 settings can be saved to the clipboard first by clicking on the Copy button located in the setting area for Test 3. Otherwise, settings will be lost when the curve is removed. The function of the Copy button is explained in the “Copy and Paste Feature” section on page 45.

Add a Test Operation. Click on the green Add a Test button at the bottom of screen to add a new test operation to the end of the test sequence. See Figure 64. Test operations can only be added sequentially from the top down.

Figure 64. The Add a Test button.

Copy and Paste Feature
The Copy and Paste feature can be used to copy TCC curve settings from one trip operation to another trip operation. This eliminates the need to re-enter TCC curve settings multiple times. Each trip operation has its own Copy and Paste buttons. See Figure 65.

Figure 65. The Copy and Paste buttons.

Note: The open interval between two adjacent operations is not copied.
Copy. To copy TCC curve settings to the clipboard, click on the Copy button for the operation being duplicated (e.g., Initial Trip or Test 1, etc.). See Figure 65. The Copy button will not be active until a curve has been completely defined.
Paste. To paste TCC curve settings from the clipboard, click on the applicable Paste button. See Figure 65. The Paste button will not be active until a Copy button is clicked.

Open Interval and O/C Sequence
Time If the reclosing sequence consists of just the Initial Trip operation (i.e., single shot to lockout), the reset time does not need to be entered. If there are two or more trip operations, the open interval must be entered between adjacent trip operations in addition to the reset time. On the screen, the setting field for the Open Interval setting is located between two adjacent trip operations; the field for the O/C Sequence Time setting is always located at the end of all trip operations. See Figure 66.

Figure 66. The Open Interval and O/C Sequence Time setting field locations.

Open Interval following Initial Trip, Test 1, or Test 2. Specify interrupter open time (in seconds) before it recloses after the initial Trip operation, after Test 1, or after Test 2, as applicable (minimum value: 0.5; maximum value: 5 [or 30 for extended open interval-capable reclosers]). See Figure 66.
O/C Sequence Time. Specify the reset time for the test sequence, in seconds (minimum value: 0.5; maximum value: 1000). If a TripSaver II recloser remains closed upon completion of an action in the test sequence–and the overcurrent element has not picked up and started timing again within this setting–the test sequence counter will reset and the TCC curve will reset to its setting defined in the Trip operation. See Figure 66.
Note: An active O/C Sequence Time timer will not expire after a TripSaver II recloser loses power. It will continue counting down until the defined duration has been reached.

TCC Curve Settings–Default Curves
The software launches with a set of default TCC curve settings that match those programmed into every standard TripSaver II recloser before it leaves the factory. This is the starting point of the configuration process. The S&C default TCC curve settings are shown below:
Initial Trip: Microprocessor Recloser S&C 104 curve; Minimum Trip Current: 100 A; Time Multiplier: x1; Reset Type: D/T (Definite Time); Reset Time: 0.1s; Advanced TCC Curve Setup: Off.

Open Interval After Initial Trip: 5s.
Sequence Coordination (Disabled): Microprocessor Recloser S&C 133 curve; Minimum Trip Current: 100 A; Time Multiplier: x2; Reset Type: D/T (Definite Time); Reset Time: 0.1s; Advanced TCC Curve Setup: Off.

Coordination Reset Time: 120s.
Test 1: Microprocessor Recloser S&C 104 curve; Minimum Trip Current: 100 A; Time Multiplier: x1; Reset Type: D/T (Definite Time); Reset Time: 0.1s; Advanced TCC Curve Setup: Off.

Open Interval After Test 1: 5s.
Test 2: Microprocessor Recloser S&C 133 curve; Minimum Trip Current: 100 A; Time Multiplier: x2; Reset Type: D/T (Definite Time); Reset Time: 0.1s; Advanced TCC Curve Setup: Off.

Open Interval After Test 2: 5s.
Test 3: Microprocessor Recloser S&C 133 curve; Minimum Trip Current: 100 A; Time Multiplier: x2; Reset Type: D/T (Definite Time); Reset Time: 0.1s; Advanced TCC Curve Setup: Off.

O/C Sequence Time: 15s.
These default settings for the setup software used while in the Standalone (offline) mode can be changed in the Standalone tab under the Options feature. See the Options feature under the Tools menu.

TCC Curve Settings–Clear Settings for a Trip Operation
To clear settings for a Trip operation, either remove the Trip operation and then reinstate it using the Remove Last Test and Add a Test buttons, or select the Blank option under the Emulated Device selection menu for that Trip operation, as shown in Figure 67.

Figure 67. The blank option for clearing the TCC setting.

All existing settings will then be erased. See Figure 68.
Note: Any unwanted curve must be removed before applying new settings to a TripSaver II recloser. Leaving a curve added with completely blank settings will not allow the settings to be applied.

Figure 68. The TCC setting erased.

TCC Curve Settings–Configure a Trip Operation
When a test is added, a new configuration area for that Test operation will be displayed, but with only two user-configurable fields available at the beginning–the Emulated Device drop-down menu and the Open Interval setting between the newly added Trip operation and the previous Trip operation. See Figure 69. For the Emulated Device drop-down menu, select one of the following four options (additional user-configurable fields will be displayed depending on what is selected):

• Microprocessor Recloser
• Fuse Link
• Hydraulic Recloser
• Blank (explained in the “TCC Curve Settings–Clear Settings for a Trip Operation” section on page 48)

Figure 69. The selections for an emulated device.

Note: When changing the selection for Emulated Device options at any time when configuring a Trip operation, all settings entered for that Trip operation will be erased. However, the Open Interval field can be edited independently.

Select a Microprocessor Recloser Curve
Emulated Device. Select the Microprocessor Recloser option. See Figure 70.

Figure 70. The Microprocessor Recloser selected.

Inverse Segment. A new Inverse Segment field will open after the Microprocessor Recloser option is selected under the Emulated Device pull-down menu. See Figure 71.

Figure 71. The Inverse Segment field.
Select various inverse curve segments from the list or select the DefiniteTime option. The term “S&C,” if present, means the inverse curve segment is an S&C-developed datapoints-based emulation of the TCC curve published by the recloser manufacturer. If the DefiniteTime option is selected, only the Definite Time-related setting fields will be displayed.
Note: When an Inverse Segment setting is selected, the curve-selection process is completed and the Test operation can be copied to the clipboard or saved to a setpoint file.

For Inverse Segment
If an inverse curve segment is selected (e.g., S&C 105), additional fields will open, as shown in Figure 72.

Figure 72. The additional fields under Inverse Segment.

Minimum Trip, A. Specify the current (in primary amperes) at which the inverse curve segment begins timing (minimum value: 5; maximum value: 400). Note: Though the maximum value available is 400 A, the software will prompt with an overload warning of 40 A for TripSaver II reclosers rated 40 A continuous, 100 A for TripSaver II reclosers rated 100 A continuous, and 200 A for TripSaver II reclosers rated 200 A continuous.
Some curves may have different ranges for the Minimum Trip setting, as indicated in the flyover text. This field is mandatory. The Minimum Trip current for 40 A and 100 A continuous TripSaver II reclosers is 5 A. The Minimum Trip current for 200-A continuous TripSaver II reclosers is 10 A. See Figure 72.
Time Multiplier. Specify the modifier for the inverse curve segment (minimum value: 0.01; maximum value: 15). Note: Some curves may have different ranges for the Time Multiplier setting, as indicated in the flyover text. This field is mandatory. See Figure 72 on page 50.
Reset Type. Select the reset method for the inverse curve segment from the drop-down list: “D/T” (Definite Time) or “E/M” (Electromechanical). (This is not to be confused with O/C Sequence Time setting. “Reset” here means how fast that curve will reset if it has picked up but the fault disappears before the TripSaver II recloser could trip.) This field is mandatory. See Figure 72 on page 50.
Reset Time, s. Specify the time delay (in seconds) before the inverse curve segment resets under D/T reset type (minimum value: 0; maximum value: 1,000). This field is mandatory. See Figure 72 on page 50.
Reset Time, s (TM1, I0A). When the Reset Type setting is E/M, the title of the reset time will be changed to “Reset Time, s (TM1, I0A).” The value specified here is the time delay (in seconds) before the inverse curve segment resets when the Time Multiplier setting is set at 1 and load current flowing is at 0 A (minimum value: 0; maximum value: 1,000). The actual reset time used by the Electromechanical Reset feature will be calculated using the following quadratic algorithm: the value in this field * the time multiplier entered/ (the load current/the minimum trip entered)^2 – 1). This field is mandatory. See Figure 73.

Figure 73. The Reset Time setting field for E/M Reset Type.

Advanced TCC Curve Setup (optional). (Click on the Advanced TCC Curve Setup button to expand/collapse area.) See Figure 74.

Figure 74. The Advanced TCC Curve Setup fields for a microprocessor recloser.

Time Adder (checkbox). Select this checkbox to enable the Time Adder setting. See Figure 74.
Time Adder, Time s. Specify a time modifier (in seconds) to add a constant time delay to the inverse curve segment. Default: 0 (minimum value: 0; maximum value: 0.25).
Max Time (checkbox). Select this checkbox to enable the Max Time setting. See Figure 74 on page 51. New in v1.9, the Max Time setting enables the setting of a maximum time duration of the current before a trip will occur. This is helpful when TCC curves are designed where the load or fault must be sustained for long durations (seconds or minutes) when the current magnitude is near the Minimum Trip threshold, before a protection Trip operation occurs according to the set TCC curve.
Max Time, Time s. Specify a maximum time (in seconds) to trip prior to inverse curve segment expiration. Curve Default: Disabled (minimum value: 0.2; maximum value: 180).
Low Current Cutoff (checkbox). Select this checkbox to enable low-current cutoff. See Figure 74.
Low Current Cutoff, Current, A. Specify the current (in primary amperes) below which the inverse curve segment is truncated.

For Definite Time
If the DefiniteTime setting is selected from the same Inverse Segment selection menu, additional fields will open, described below. See Figure 75. Note: When the DefiniteTime setting is selected, the test operation can be copied to the clipboard or saved to a setpoint file.

Figure 75. The additional fields when DefiniteTime is selected under Inverse Segment.

Current, A. Specify the current (in primary amperes) at which the DefiniteTime setting begins timing (minimum value: 5; maximum value: 400). This field is mandatory. See Figure 75.
Time, s. Specify the time delay (in seconds) after which the DefiniteTime setting trips (minimum value: 0; maximum value: 1,000). This field is mandatory. See Figure 75.
Reset Type. Select the reset method for the DefiniteTime setting from the drop-down list: “D/T” (Definite Time) or “E/M” (Electromechanical). (This not to be confused with the O/C Sequence Time setting. “Reset” here means how fast that curve will reset if it has picked up but fault disappears before the TripSaver II recloser could trip.) This field is mandatory. See Figure 75.
Reset Time, s. Specify the time delay (in seconds) before DefiniteTime segment resets under “D/T reset type” (minimum value: 0; maximum value: 1,000). This field is mandatory. See Figure 75.
Reset Time, s (I0A). When the Reset Type is “E/M”, the title of the Reset Time field will be changed to “Reset Time, s (I0A)”. The value specified here is the time delay (in seconds) before the DefiniteTime element resets when load current flowing is at 0 A (minimum value: 0; maximum value: 1,000). The actual reset time used by the electromechanical reset will be calculated using the following quadratic algorithm: the value in this field/ (the load current / the current entered)^2 – 1). This field is mandatory. See Figure 76.

NR Curve Settings Screen

NOTICE
In service center configuration software versions 1 .6 and earlier, the MODESELECTOR lever in the Down position or in R-NR mode would not go through the reclosing sequence but would operate instantaneously in response to a Trip event using the current setting set under the Initial Trip trip-operation field on the TCC Curve Setting screen . (See the “TCC Curve Settings–General” section on page 43 .) The new NR Curve Settings screen allows the user to program different TCC curves specifically for the MODE-SELECTOR lever when in NR or R-NR mode .

The NR Curve Settings screen is where the curves used by the TripSaver II recloser when the MODE-SELECTOR lever is in the Down position or the recloser is in R-NR mode are set. See Figure 88. All curves in the NR Curve Settings menu are set the same and have the same setting ranges as the curves in the TCC Curve Settings menu.

Figure 88. The NR Curve Settings screen.

Standard NR
The Standard NR setting allows the user to select any curve in the library when NR or R-NR mode are active. In previous versions of the TripSaver II recloser firmware, the NR Curve was factory-set as the instantaneous curve and was not configurable. This setting will be used by the TripSaver II recloser when the MODE-SELECTOR lever is in the Down position or when the recloser is in the R-NR mode.
The recloser will not go through a reclosing sequence but will respond to the TCC set in the Standard NR setting field. The default setting is illustrated in Figure 89. Note: To make the Standard NR setting behave like an instantaneous curve, as was standard in Service Center Configuration Software version 1.6 and earlier, select the Definite Time for the Inverse Segment mode and make sure the minimum trip value of the Standard NR setting is the same as the minimum trip value of the initial trip curve as shown in Figure 89.

Figure 89. The Standard NR setting field.

Post Fault Wakeup NR
The Post Fault Wakeup NR setting is configured when a separate curve is desired when the TripSaver II recloser is energized or is closed into its mounting after a drop-open event occurs. See Figure 90. This setting will be used by the TripSaver II recloser when the MODE-SELECTOR lever is in the Down position or when the recloser is in the R-NR mode. After 10 cycles, if a current above the Current, A setting is not detected, the Post Fault Wakeup TCC curve will revert to the Standard NR curve settings.
The Post Fault Wakeup NR setting will be used after the recloser has dropped open in response to fault current, or another event that results in the recloser dropping open (i.e. LMO or Gang Operation). In situations where the recloser is waking up or is closed into the mounting after being de-energized when it did not experience a drop open event, the Cold Wakeup NR setting will be used. See Figure 91 on page 62.
If a Post Fault Wakeup NR setting is not required, set the TCC curve to the same settings as the Standard NR TCC setting.

Figure 90. The Post Fault Wakeup NR setting field.

Cold Wakeup NR
The Cold Wakeup NR setting is configured when a separate curve is desired in response to a cold wakeup of the TripSaver II recloser. See Figure 91. In most cases, this is a slower curve. This setting will be used by the TripSaver II recloser when the MODE-SELECTOR lever is in the Down position or when the recloser is in the R-NR mode. After 10 cycles, if a current above the Current, A setting is not detected, the Cold Wakeup NR curve will revert to the Standard NR curve.
The Cold Wakeup TCC curve will not be used in a “post-fault” situation, where the load is being picked up after the TripSaver II recloser has previously dropped open. In those cases, the Post Fault Wakeup NR curve will be used. See Figure 90 on page 61.
If a Cold Wakeup NR setting is not required, set the TCC curve to the same settings as the Standard NR setting.

Figure 91. The Cold Wakeup NR setting field.

Sectionalizing Settings Screen

The TripSaver II recloser features a Sectionalizing function in both the 4-kA and 6.3-kA rated models. When enabled, a TripSaver II recloser will start its secondary protection function–the Sectionalizing function–over a user- specified range of fault currents when the source-side circuit breaker or recloser for whatever reason trips faster than the TripSaver II recloser’s TCC overcurrent protection. It will count the number of operations of the source- side circuit breaker or recloser and will drop open after a user-specified number of counts. The Sectionalizing Settings screen is shown in Figure 92.

Figure 92. The Sectionalizing Settings screen.

Note: This Sectionalizing function serves as a backup protection function and always works in parallel with the TCC overcurrent protection. Enabling this feature does not automatically switch the TCC overcurrent protection off and make the TripSaver II recloser a pure sectionalizer. To make a TripSaver II recloser work as a pure sectionalizer, set the High Current Cutoff setting to a value less than the Sectionalizing Mode Starting Current setting.

High Current Cutoff
The High Current Cutoff setting is a global setting that applies to all TCC curves selected. When enabled, the overcurrent elements for all TCC curves including NR curves will not time and trip on fault current above the value entered. Protection will be provided by the upstream device.
High Current Cutoff (Enabled or Disabled). Select the Enabled tab to enable the High Current Cutoff setting for all TCC curves. See Figure 92 on page 62. High Current Cutoff, Current A. Specify current (in amperes) above which the overcurrent element of all enabled TCC curves will not time and trip (minimum value: 400; maximum value: 6,300). See Figure 92. This value must be less than or equal to the interrupting rating of the recloser. It also must be equal or greater than the Sectionalizing Mode Start Current setting to avoid a gap in protection.

Sectionalizing Mode
Sectionalizing Mode. Select the Enabled or Disabled option from the Sectionalizing Mode pull-down menu list. See Figure 92. Note: When toggling this selection at any time when configuring the sectionalizing settings, all data entered for sectionalizing settings will be erased.
Sectionalizing Mode Counts. Specify the number of source-side circuit breaker or recloser trip operations the TripSaver II recloser will count up to before dropping open (minimum value: 1; maximum value: 9; integer). See Figure 92.
Sectionalizing Mode Reset Time, s. Specify the length of time the Sectionalizing logic waits for an additional sectionalizing event to occur before it resets, in seconds (minimum value: 0.5; maximum value: 1,000). See Figure 92.
Sectionalizing Mode Starting Current, A. Specify the current value, in primary amperes, at which the Sectionalizing mode starts (minimum value: 10; maximum value: 6,500). See Figure 92. Note: This value must be less or equal to the High Current Cutoff setting to avoid a gap in protection.

LCD Screen Settings Screen

LCD Screen Settings Screen–General
The TripSaver II recloser uses a non-volatile liquid-crystal-display (LCD) to show various status and operational information. The screen has two operating modes: Normal screen and Display screen. The LCD shows the Normal screen most of the time. The Display screen parameters may be viewed by toggling the mode selector. TripSaver II reclosers will scroll through the user-configurable Display screen items the specified number of times before the screen returns to the Normal screen.

Status Screen

The Status screen is available under the Connected (online) mode or when a snapshot file is open. When a TripSaver II recloser is connected, the Status screen will be the first screen to open, and it will populate with data from the TripSaver II recloser. The Status screen presents status information, a summary of TCC curve settings, and general recloser information. This screen is view-only; there are no data-entry fields. See Figure 101.

Figure 101. The Status screen.

Status Screen –Status Information
The status information is shown at the top section of this screen. See Figure 102.

Figure 102. The Status information area.

Photo. Depending on the TripSaver II recloser, a photo of either a 15-kV (15.5-kV max) or 25-kV (29-kV max) recloser will be displayed. If a TripSaver II recloser is furnished with the Extended Open Interval option (“-O”), a black and white clock face icon indicating “30s” will be displayed on the top right side in the photo frame. See Figure 102 on page 70 and Figure 103.

Figure 103. Photos of 15-kV and 25-kV TripSaver II reclosers.

Current, A. This is the instantaneous magnitude of the current flowing through the control, in primary amperes. It’s located below the photo. Current displayed will typically be 0 A~1 A when the TripSaver II recloser is being powered by the power module during configuration. See Figure 102 on page 70.
Interrupter Contacts. This indicates whether the vacuum interrupter contacts of the connected TripSaver II recloser are presently open or closed. Note: During a functional test, it is normal for the vacuum interrupter contacts to show “Transit,” which means the interrupter contacts are opening or closing. See Figure 102.
Mode. This indicates the operational mode of the TripSaver II recloser: AUTO (lever up), NR (lever down), or R-NR (lever up). In Auto mode, a TripSaver II recloser will perform open or reclose operations according to the pre-selected TCC curves. In NR (Non-Reclose) and R-NR (Remote-Non-Reclose) mode, a TripSaver II recloser will not reclose; it will trip once on the applicable user-specified NR curve or the default instantaneous curve if the NR curve settings have not been configured (the minimum trip current comes from the initial trip curve) and then drop open. See Figure 102. The TripSaver II recloser automatically resets approximately 2 seconds after it drops open.
Sectionalizing Mode. This indicates whether the Sectionalizing feature is presently enabled or disabled in the connected TripSaver II recloser. See Figure 102.
Sectionalizing Counts. This indicates the number of source-side circuit breaker or recloser tripping operations the enabled Sectionalizing feature counts up to before commanding a TripSaver II recloser to drop open. The field is grayed out if the Sectionalizing feature is disabled. See Figure 102.
Battery Charge Level. This field is only displayed if a recloser is furnished with the Extended Open Interval option (“-O”). It indicates the battery state of charge, in percent. The battery state of charge is also represented by a blue “Battery Charge Level” bar at the bottom of the screen, similar to the “Main Cap Charge” bar. See Figure 102.
Battery Status. This field is only displayed if a recloser is furnished with the Extended Open Interval option (“-O”). It indicates the status of the battery that is used to support the extended open interval. See Figure 102.
OK: The battery is functioning normally.
Error: This indicates a battery problem.

# of Operations. This indicates the number of vacuum interrupter open operations registered in total. See Figure 102 on page 70.
Remaining Contact Wear in %. This indicates the remaining vacuum interrupter contact wear, in percent. See Figure 102.
Last Fault Current, A. This indicates the fundamental-frequency magnitude of the last fault, in primary amperes, measured just prior to the opening of the vacuum interrupter contacts. See Figure 102.
Status. This displays the status of the control. See Figure 102. The following status messages can be displayed.

• OK: The TripSaver II recloser is functioning normally and is in the Idle state.
• Waiting to Open VI: This indicates the vacuum interrupter contacts are waiting to open.
• Waiting to Close VI: This indicates the vacuum interrupter contacts are waiting to close.
• Open Interval: This indicates the state when TripSaver II recloser is in the Open Interval state.
• Waiting to Drop Open: This indicates the state when TripSaver II recloser is waiting to drop open.
• Waiting to Reset Drop-Open: This indicates the state when TripSaver II recloser is waiting to reset the drop-open mechanism. This is a relatively short transient state.
• Dropped Open: This indicates the TripSaver II recloser has dropped open. This is a relatively short transient state, after which the status will go back to being “OK”.
• Error: This indicates an error has just occurred. This is a transient state and only temporarily displays immediately after an error event.
• Service Now: This appears when a TripSaver II recloser cannot release the drop-open mechanism after consecutive re-tries, when the vacuum interrupter contacts cannot open after consecutive re-tries, or when a TripSaver II recloser is no longer capable of interrupting a fault when remaining contact wear is at 0%. When a TripSaver II recloser enters the Service Now state, the LCD will be locked with a special Service Now screen: the right side of the screen will display the vacuum interrupter status (“O” for Open; “I” for Closed; “X” for an error situation when the recloser cannot sense the vacuum interrupter status.) and the left side of the screen will display an “!” symbol, indicating immediate attention is needed. Rotating the MODE SELECTOR lever, applying a 9-Volt Lithium L522 battery, or applying the Service Center Configurability power module will not unlock the screen. The TripSaver II recloser must be returned to S&C Electric Company for service.

Note: The Status field displays “OK” most of the time during configuration. Changes in status will be seen during a functional test. However, some of the fast transient events may not be captured on the screen. To optimize the performance of communications system, the software is designed to pull status information from the connected TripSaver II recloser only once per second. Therefore, some fast transient events may have already expired by the time TripSaver II recloser starts to transmit its latest status information to the software.

Status Screen–TCC Curve Summary
The “TCC Curve Summary” section is expanded by default. You can collapse the section by clicking on the green title row. This screen summarizes the basic information of the configured TCC curves residing in the connected TripSaver II recloser. See Figure 104.

Figure 104. The TCC Curve Summary area.

The following curve information is extracted from the connected recloser.

• Emulated Device. The type of device the curve is emulating. It displays either
  Microprocessor Recloser, Fuse Link, or Hydraulic Recloser. See Figure 105.

Event Logs Screen

The Event Logs screen provides eight different historical counts, including the number of interrupter operations and recloser drop-opens, of the connected TripSaver II recloser, and the duration and current level of the last 25 trip events. The Event Logs screen is shown in Figure 107.

Figure 107. The Event Logs screen.

Event Logs Screen–Historical Counts
Number of Forced Interrupter Closes. This is the number of times the vacuum interrupter has been manually reset using the Service Center Configuration Kit power module, cordless power module, or a 9-Volt Lithium L522 battery. See Figure 107.
Number of Interrupter Open Operations due to Overcurrent. This is the number of times the vacuum interrupter contacts have opened due to an overcurrent condition. See Figure 107.
Total Number of Interrupter Open Operations. This is the total number of times the vacuum interrupter contacts have opened. See Figure 107.
Number of Drop-Opens due to Overcurrent. This is the number of times the TripSaver II recloser has dropped open because of an overcurrent condition. See Figure 107 on page 75.
Number of Drop-Opens Due to Overload. This is the number of times the TripSaver II recloser has dropped open because of an overload condition. See Figure 107.

Number of Drop-Opens Due to Local Manual Open. This is the number of times the TripSaver II recloser has dropped open, triggered by the Local Manual Open feature. See Figure 107.
Total Number of Drop-Opens. This is the total number of times the TripSaver II recloser has dropped open, including the number of drop-opens during functional test and triggered by the Local Manual Open feature. See Figure 107.

Trip Events
The TripSaver II Service Center Configuration Software allows viewing the relative time stamp, duration, and current level of the last 25 interrupter trip events in the Trip Events table. When the table is full (loaded with 25 events), each new event will overwrite the oldest event in the table. For example, the 26th event will overwrite the 1st event shown in the table.
Note: While the Trip Events table only displays the last 25 interrupter trip events for user review, the firmware uses a separate memory to store full event logs for future engineering analysis use. The full log can be obtained by saving a snapshot file.
The Trip Events table is located in the lower section of the Event Logs screen. Five columns of data are presented. See Figure 108.

Figure 108. The Trip Events table.

Event. Each new event is assigned an event ID number in ascending order. The newest event is displayed in the top row of the table, and the oldest event is displayed in the bottom row. See Figure 109.

Figure 109. The Event ID column.

Tripped On. This indicates the event that caused the vacuum interrupter to trip. See Figure 110.

Figure 110. The column indicating the type of event the vacuum interrupter was tripped on.

The following events can be displayed.

• Overload. This indicates the vacuum interrupter tripped because of an Overload condition and the TripSaver II recloser dropped open.

• Sectionalizer. This indicates the vacuum interrupter tripped when the enabled
  Sectionalizing feature commanded the TripSaver II recloser to drop open after the preset count was reached.

• NR#0, NR#1, NR#2. This indicates the vacuum interrupter tripped because of an Overcurrent condition while the recloser was in NR or R-NR mode and the recloser dropped open.

• TCC0 or TCC1 or TCC2 or TCC3. This indicates which trip or test operation the TripSaver II recloser was on when the vacuum interrupter tripping event happened because of an Overcurrent condition under AUTO mode. TCC0: Initial Trip; TCC1: Test 1; TCC2: Test 2; TCC3: Test 3.

• Sequence Coordination trip operation. When the feature is configured and enabled, and when the TripSaver II recloser detects a fault that exceeds the TCC0 minimum trip setting but the fault duration is not sufficient to cause TCC0 to trip, the TripSaver II recloser will assume the downline device has operated. The recloser will switch protection from TCC0 to its Sequence Coordination settings.

If the fault isn’t cleared by the downstream device, the Sequence Coordination curve will start timing and trip. A Sequence Coordination trip operation will then show as “SC0” in the event log. See Figure 111. If the fault persists beyond SC0, the TripSaver II recloser will use the remaining settings in the protection sequence, including TCC1, TCC2, and TCC3, as programmed. For more information on the Sequence Coordination feature, see the description on page 44 and in S&C Information Bulletin 461-50, “TripSaver® II Cutout-Mounted Recloser: Sequence Coordination Application Guide.”

Figure 111. An example of a sequence coordination trip in the Trip Events log.

• LMO. This indicates the vacuum interrupter tripped because of a Local Manual Open command, and the TripSaver II recloser dropped open.
• Suspicious. This indicates the S&C-determined flag for suspicious malicious local manual open attempts has been detected. The S&C-determined flag is defined as: 10 consecutive MODE SELECTOR lever operations (moving the lever down and then back up is counted as two operations) within a 60-second window, when the Local Manual Open feature is disabled. The logic only monitors the condition when the recloser is vertical.

Relative Time, DD-HH:MM:SS.000. This indicates the relative time stamp of vacuum interrupter trip events in the format of days, hours, minutes, seconds and milliseconds. A TripSaver II recloser has an internal timer that starts when each recloser leaves the S&C factory. The timer saves a relative time stamp into memory immediately before the timer stops five hours after the recloser loses power. The internal timer will start from this saved time stamp when the TripSaver II recloser is powered up again. See Figure 112.

Figure 112. The column displaying Relative Time timestamp.

Duration, ms. This indicates the duration (defined here) of each event shown in the Tripped On column, in milliseconds. See Figure 113.

Figure 113. The column displaying duration for each event.

• For Overcurrent (TCC0, TCC1, TCC2, TCC3, SC0, and the NR curves): This indicates the duration of the fault.
• For Overload: This indicates the duration of the overload drop-open event during which the current measured was above 100 A.
• For Sectionalizer: This indicates the duration during which the current measured during the last sectionalizing event, before the enabled Sectionalizing feature commanded the TripSaver II recloser to drop open, was above the Sectionalizing Mode Starting Current setpoint.
• For LMO: This value will be 0.
• For Suspicious: This value will be 0.

Current, A. This indicates the current level (defined here) of each event shown in the “Tripped On” column, in primary amperes. See Figure 114.

Figure 114. The column displaying current level for each event.

• For Overcurrent (TCC0, TCC1, TCC2, TCC3, SC0, and the NR curves): This indicates the value of the current measured just before the vacuum interrupter contacts opened.
• For Overload: This indicates the value of the current measured just before the vacuum interrupter contacts opened.
• For Sectionalizer: This indicates the maximum value of the current measured during the last sectionalizing event before the enabled Sectionalizing feature commanded the TripSaver II recloser to drop open.
• For LMO: This indicates the value of the load current measured just before the vacuum interrupter contacts opened by the Local Manual Open command.
•  For Suspicious: This indicates the value of the load current measured when a suspicious local manual open attempt was detected.
  Clear All Events. Clicking on this button will clear the log for “Trip Events” in the connected TripSaver II recloser. This can be useful prior to deploying a TripSaver II recloser to a different location. This button is grayed out when viewing a snapshot file. See Figure 108 on page 76.
  Note 1: The command executes immediately after clicking on the button. Save a snapshot before clearing the log.
  Note 2: Clicking on this button does not reset the relative timer.
  Note 3: Clicking on this button does not erase anything from the memory used to store full event logs for use by S&C Technical Support.

Functional Test Screen

Functional Test Screen—General
Simulation-based functional tests can be performed on this screen to verify the vacuum interrupter and the drop-open mechanism respond correctly to the applied TCC curve settings. The Functional Test screen is shown in Figure 115.

Figure 115. The Functional Test screen.

Specifically the test verifies the following:

• Main power supply capacitor inside the TripSaver II recloser will charge.
• Vacuum interrupter contacts will open.
• Vacuum interrupter contacts will close.
• Drop-open mechanism will respond correctly at the end of a permanent fault simulation.
• The test operations correctly sequence after the vacuum interrupter contacts are closed.
• The test operations reset at the end of a permanent fault simulation.
• The number of trip operations matches the setting.
• The Open interval matches the setting.
• The Sequence Reset Time matches the setting.

Note: This is not a primary injection test and does not involve any actual current.

Functional Test Screen—Device Status
The upper section of the Functional Test screen monitors device status relevant to the functional test. See Figure 116.

Figure 116. The Device Status area.

Interrupter Contacts. This indicates whether the vacuum interrupter contacts of the connected TripSaver II recloser are presently open or closed. See Figure 116. Note: During a functional test, it’s normal for the vacuum interrupter contacts to show “Transit,” which means the interrupter contacts are opening or closing.
Mode. This indicates the position of the MODE SELECTOR lever: AUTO (up), Remote-NR (up), or NR (down). In AUTO mode, the TripSaver II recloser will perform an open and reclose operation during the functional test according to the applied TCC curves. In Remote-NR or NR (non-reclose) mode, the TripSaver II recloser will not reclose during the functional test; it will open the vacuum interrupter contacts instantaneously and release the drop-open mechanism after a simulation button is clicked. The TripSaver II recloser will drop open and reset itself afterward.
Orientation. This indicates whether the TripSaver II recloser is closed into a fuse cutout mounting (in the vertical position) or is in the Dropped- Open position (in the horizontal position).
Status. This field displays the same status items as the Status screen. The following can be shown:

• Ok: The TripSaver II recloser is functioning normally and is in the Idle state.
• Waiting to Open VI: This indicates the vacuum interrupter contacts are waiting to open.
• Waiting to Close VI: This indicates the vacuum interrupter contacts are waiting to close.
• Open Interval: This indicates the state when the TripSaver II recloser is in the open interval.
• Waiting to Drop Open: This indicates the state when the TripSaver II recloser is waiting to drop open.
• Waiting to Reset Drop-Open: This indicates the state when TripSaver II recloser is waiting to reset the drop-open mechanism. This is a relatively short transient state.
• Dropped Open: This indicates the TripSaver II recloser has dropped open. This is a relatively short transient state, after which the status will go back to being “OK”.
• Service Now: This appears when the TripSaver II recloser cannot release the dropopen mechanism after consecutive re-tries, when the vacuum interrupter contacts cannot open after consecutive re-tries, or when the TripSaver II recloser is no  longer capable of interrupting a fault when remaining contact wear is at 0%. When the  TripSaver II recloser enters the Service Now state, the LCD screen will display a special Service Now screen: the right side of the screen will display the vacuum interrupter status (“O” for open; “I” for closed), and the left side of the screen will display an “!” symbol, indicating immediate attention is needed. Rotating the MODE SELECTOR lever, applying a 9-Volt lithium L522 battery, or the Service Center Configurability power module will not be able to unlock the screen. The TripSaver II recloser must be returned to S&C Electric Company for service.
• Error: This indicates an error has just occurred. This is a transient state and only temporarily displays immediately after an error event.

Note: During the functional test, some of the fast transient events may not be captured on the screen. To optimize the performance of communications subsystems, the software is designed to pull status information from the connected TripSaver II recloser only once per second. Therefore, some fast transient events may have already expired by the time TripSaver II recloser starts to transmit its latest status information to the software.
Total Number of Interrupter Open Operations. This is the total number of times the vacuum interrupter contacts have opened. The value will increment by 1 for each interrupter open operation performed during the functional test.
Total Number of Drop-Opens. This is the total number of times the TripSaver II recloser has dropped open. The value will increment by 1 for each drop-open operation performed during the functional test.

Functional Test Screen—Functional Test
The lower section of the Functional Test screen is where the functional tests are performed. This section also monitors two additional pieces of information useful to the functional test. See Figure 117.

Figure 117. The Functional Test command area.

Simulation Status. This field displays control status relevant to the functional test.
The following can be displayed:

• Idle: The TripSaver II recloser is functioning normally and is in the Idle state.
• Charging Caps: This indicates the main power supply capacitors inside the TripSaver II recloser are charging. When this message is present, the blue “Main Caps Charge” bar at the bottom of the screen can be observed lengthening.
• Waiting to Reclose: This indicates the vacuum interrupter contacts are waiting to close.
• Waiting to Drop-open: This indicates the TripSaver II recloser is waiting to drop open.

Sequence Step. This field indicates which trip or test operation the connected TripSaver II recloser will use for the next fault simulation. TCC0: Initial Trip; TCC1: Test 1; TCC2: Test 2; TCC3: Test 3. This number will reset to TCC0 when 1) no additional temporary fault simulation commands are given before the sequence reset timer expires or 2) at the end of a permanent fault simulation.
Simulate Temporary Fault. Click on the green Simulate Temporary Fault button to simulate a temporary fault.

The main power supply capacitors will start to charge, and the Simulation Status field will display “Charging Caps.” The blue Main Caps Charge indicator at the bottom of the screen will start to fill up the empty space. The vacuum interrupter contacts will open after the main capacitors are fully charged. When the interrupter contacts are open, the full blue “Main Caps Charge” bar recedes immediately. See Figure 118 for an example of what is displayed on the Functional Test screen during the open interval.

Figure 118. The status during functional test open interval.

The vacuum interrupter contacts will reclose after the configured open- interval time has elapsed, and the operating sequence will step to the next Trip operation; the TripSaver II recloser is now ready for another fault simulation. Perform another temporary fault simulation by clicking on the button again before the sequence-reset time expires.
Otherwise, the sequence step will reset back to the initial-trip curve. When the sequence step reaches the last configured Trip operation, an additional temporary fault simulation within the sequence reset time will release the drop-open mechanism and the TripSaver II recloser will drop open.
Simulate Permanent Fault. Click on the green Simulate Permanent Fault button to simulate a permanent fault. See Figure 118.

NOTICE
For TripSaver II reclosers with firmware version 1 .7 or previous, make sure the trunnion of the recloser is pointing up when performing testing . Performing testing with the trunnion facing down, or pointing to the side may cause the TripSaver II recloser to enter the Service Now state and display the Service Now screen . See the “End of Interrupting Capability and Service Now Screen” topic in the “Troubleshooting” section of S&C Instruction Sheet 461-502 for more information on the Service Now screen .
Similar to the temporary fault simulation, the main power supply capacitors will start to charge first, and the Simulation Status field will display “Charging Caps.” After the main capacitors are fully charged each time, the TripSaver II recloser will open and reclose based on the configured operating sequence and eventually release the drop-open mechanism. The TripSaver II recloser will then drop open and reset.
Clicking on the Simulate Permanent Fault button before the sequence-reset time expires after a temporary fault simulation is performed will immediately start a permanent fault simulation from the beginning -TCC0.

NOTICE
Clicking either of the two green fault-simulation buttons when in NR or R-NR mode or when only the Initial Trip curve is applied will cause the recloser to operate “single shot to drop open .”

Note: To properly simulate a Drop Open operation, the TripSaver II recloser must be installed in a present-production (“-R10” or “-R11”) S&C cutout mounting. In the absence of a cutout mounting, always place the TripSaver II recloser horizontally on a flat surface with the trunnion pointing up when simulating a permanent fault. The recloser will still go through the entire sequence and release the drop-open mechanism at the end. However, the drop-open mechanism must be reset manually by either pulling up on the trunnion or by installing the TripSaver II recloser into a cutout mounting. The drop-open mechanism is fully reset when the trunnion is no longer loosely movable. The Functional Test feature was not designed to simulate the “Iced-on-the-pole” scenario when a TripSaver II recloser is powered by the Service Center Configuration power module. Do not hold the TripSaver II recloser in the mounting after the drop- open mechanism has been released when using a power module.
Abort Simulation. Click on the yellow Abort Simulation button to stop the ongoing simulation. The blue “Main Caps Charge” bar recedes after this button is clicked.
See Figure 118 on page 84.

Local Manual Open Settings

How the Local Manual Open Works
TripSaver II reclosers loaded with firmware version 1.9, 1.8, 1.7, and 1.6 have a Local Manual Open (LMO) feature for loadbreaking without the use of the Loadbuster®—The S&C Loadbreak Tool. When enabled, this feature provides a manual operation sequence that commands the TripSaver II recloser to open the vacuum interrupter contacts and drop open. A TripSaver II recloser must be powered and installed vertically in a cutout mounting for the LMO feature to work.
The MODE-SELECTOR lever controls the LMO feature. The Open command state is triggered by operating the MODE-SELECTOR lever X number of times within a Y-second window when the TripSaver II recloser is in the vertical position. When the triggering condition has been met, the TripSaver II recloser starts the open time-delay sequence. For the next 10 seconds, an “LMO Cancel?” prompt will appear on the LCD screen for cancellation. The LMO command can be cancelled by any operation
of the MODE-SELECTOR lever. If the MODE-SELECTOR lever is operated during this time, an “LMO Cancelled” message will briefly appear on the LCD screen to indicate the user has cancelled the operation.
If the command is not cancelled within 10 seconds, a “WALK AWAY” message will display on the LCD screen, indicating the start of the 20-second operation timer intended to allow the operator to comply with any operating-distance requirements specified by the utility work practices.
During the walk-away period, the operator can no longer cancel the Open operation.
At the end of the walk-away period, the TripSaver II recloser will open the vacuum interrupter contacts to interrupt the load current, then drop open and reclose the contacts after the tilt sensor indicates a completed drop-open function. See Figure 119 for a flowchart of the LMO feature sequence.

Figure 119. The LMO feature sequence.

It is important to keep in mind the following:

• When the LMO feature is enabled, a new LCD screen titled “LMO” will be automatically displayed under the LCD scrolling screen sequence as its first scrolling screen, with the X value shown on the left and the Y value shown on the right. This screen is not displayed when the LMO feature is disabled.
• The mode selector operation counter registers a single movement starting either in the Up or Down position of the lever as an operation. Moving the lever down and then back up would be counted as two operations.
• If the operation time window (Y) expires before (X) lever operations are completed, the command sequence will be terminated. The operation counter will reset to zero; any additional lever operations will begin the count toward a new command sequence.
• If the TripSaver II recloser detects a fault while a user is performing the LMO command, the command sequence will reset before the recloser trips, and the protection sequence of the TripSaver II recloser will operate normally. The Reclose/NonReclose function will be selected based on the operating lever position at the time the  TripSaver II recloser trips. Figures 120 through 124 on page 87 show how the LCD screens appear.
• LMO events will be recorded in the Event log.

When the LMO feature is disabled, the TripSaver II recloser will not drop open, no matter how many times the MODE-SELECTOR lever is operated. However, if 10 MODE-SELECTOR lever operations are detected within a 60-second timeframe when the mode is disabled and the recloser is in the vertical position, the recloser will display a screen showing “LMO XXXXX” to remind the line crew the LMO feature is disabled (see Figure 124). At the same time, to maximize system security, the recloser will consider that as a suspicious malicious attempt, and if the TripSaver II recloser is connected to remote communications, the recloser will send an unsolicited alert. This activity will also be recorded in the event log.

Figure 120. The LMO is enabled with the operations count and time window.

User-Configurable Inputs
User configuration inputs for the Local Manual Open feature are shown in Figure 125.

Figure 125. The Local Manual Open Settings screen.

Operation Count (X). Enter an integer to specify the LMO trigger condition (minimum value: 6; maximum value: 16).
Operation Time Window, s (Y). Enter an integer to specify the time window within which the LMO command sequence must be completed or it will expire (minimum value: 30; maximum value: 180; increment: 10).
Disabling LMO. “0” is accepted as a valid entry for both of these two user- configurable fields. The LMO function can be disabled by setting either or both values to “0”.
The factory default setting for the Standalone (offline) mode is the Disabled state, with both fields set to “0.” All TripSaver II reclosers will leave S&C factory with the LMO feature disabled unless specified otherwise via S&C optional factory programming.

Communication Settings Screen

The Communication Settings screen is where the TripSaver II recloser’s Communication mode and where the Side-Magnet Radio Enabling function are configured. See Figure 126.

The Apply Communication Mode button has been newly added to assist in the following two situations: when changing an installed TripSaver II recloser from the Non- Gateway Mode to the Gateway Mode setting in the field, or when encountering gateway commissioning difficulties and toggling from the Gateway Mode to the Non- Gateway Mode setting and back to the Gateway Mode setting is required .
This button is meant to be a quick way of changing both the Communication Mode and the Side-magnet Radio Enabling Function settings . To change the communication  mode and apply other settings at the same time (TCC, NR, Sectionalizing, etc .,) click on the Apply button on the menu bar .
When the Gateway Mode setting is enabled, the Side-magnet Radio Enabling Function setting will be automatically disabled, and its menu field will become blank and grayed out.
The Communication mode is automatically set to the Non-Gateway Mode setting for the standard 5s open interval recloser, and the field is hidden because the standard 5s  model is unable to communicate with a TripSaver II Communications Gateway.
The Side-magnet Radio Enabling Function setting is still available. When placed in the Gateway Mode setting, a TripSaver II recloser with the extended open interval will no  longer be able to communicate directly to a PC when a side magnet is attached, and the Side-magnet Radio Enabling Function setting will be disabled, and the Side-magnet  Radio Enabling Function menu will be blank and grayed out.
The recloser will, however, still be able to communicate directly to a PC when the service center configuration power module or cordless power module is attached.
When the service center configuration software is in Standalone mode, the default Communication Mode setting is Non-Gateway Mode. When creating a setpoint file, the  Gateway Mode setting can be saved to the setpoint file by selecting it and clicking on the Save Setpoints button on the menu bar. When a snapshot file from a TripSaver II  recloser model with the extended open interval capability is open, the state of the associated TripSaver II recloser’s communications mode will be shown.

All TripSaver II reclosers are factory-set to the Non-Gateway Mode setting unless specified otherwise via optional factory programming. Always select the NonGateway Mode setting on the TripSaver II Configuration Worksheet (Form 888) and in the user-provided setpoints file when requesting factory programming for standard 5s TripSaver II reclosers.

NOTICE
When the Service Center Configuration Software is communicating with a TripSaver II recloser via the communications gateway, the firmware update function will be  disabled . Firmware updates can only be done using the USB transceiver from the Service Center Configuration Kit .

Side-Magnet Radio Enabling Function
Use the drop-down list to enable or disable the Side-magnet Radio Enabling Function setting and click on the Apply button on the menu bar. See Figure 128. The Side- magnet Radio Enabling Function setting, which works only under the Non-Gateway Mode setting, is described in more detail in S&C Instruction Sheet 461-507, “Enabling  Pole-Top Communication via the TripSaver II Magnet Tool.”
The default setting for the Standalone mode is the Enabled setting. All TripSaver II reclosers will leave the S&C factory with the function enabled unless optional factory programming specifies otherwise. When disabled, placing a side-magnet on the recloser will not establish communication directly between a TripSaver II recloser and a PC, even when the TripSaver II recloser is powered. The TripSaver II recloser will, however, still be able to communicate directly to a PC when removed from the pole and using the service center configuration power module or on the pole using the cordless power module.The default setting for the Standalone mode is the Enabled setting. All TripSaver II reclosers will leave the S&C factory with the function enabled unless optional factory programming specifies otherwise.

The TripSaver II recloser will, however, still be able to communicate directly to a PC when removed from the pole and using the service center configuration power module or on the pole using the cordless power module.
This setting field is not available for selection and will be grayed out when the Gateway Mode setting under Communication mode is selected. When placed in the Gateway Mode setting, a TripSaver II recloser with the Extended Open Interval option is only able to communicate directly to a communications gateway and is unable to communicate directly to a PC when a side-magnet is attached. The recloser will, however, still be able to communicate directly to a PC when the service center configuration power module is attached.

R–NR Functions Screen

R-NR Reset
TripSaver II reclosers with the Extended Open Interval option (“-O”) can communicate with the TripSaver II Communication Gateway, and the user can remotely set the recloser to Remote Non-Reclose (R-NR) operational mode and back to Auto mode when the MODE SELECTOR lever is in the Up position. To avoid a situation where the TripSaver II recloser is permanently stuck in the R-NR mode when remote communications are not available, the user can set the operational mode back to the Auto setting locally by using the R-NR Reset feature when a TripSaver II recloser is connected to the S&C TripSaver II Service Center Configuration Software. See Figure 129.

Figure 129. The R-NR Reset screen.

The feature will not be hidden for standard 5s TripSaver II reclosers that do not have the Extended Open Interval option capability. The operational mode will always be in the Auto setting when the lever is in the Up position. Mode when lever is up. This indicates the state of the operational mode when the lever is in the Up position. The Reset function is only available when this field displays “R-NR”. Set Mode to AUTO. Click on this button to set the operational mode when the lever is in the Up position back to the Auto setting from R-NR mode. When the mode is set to the Auto setting, the button will be grayed out and no longer available for clicking. Note: This feature does not allow users to set the recloser to R-NR mode from Auto mode locally. Also, changing the connection to Non-Gateway mode does not automatically reset the recloser to Auto mode from R-NR mode.

Temp Auto
A SCADA communication can place a TripSaver II recloser with the Extended Open Interval option (“-O”) into the Remote-Non-Reclose (R-NR) mode when remote communications are enabled via the TripSaver II Communications Gateway. After the recloser drops open under R-NR mode, the recloser will operate in Auto mode if it is closed into its mounting with the MODE-SELECTOR lever in the Up position for a period of five minutes after re-energization. This is called Temporary Auto mode.
This Temporary Auto mode can be disabled by clicking on the Disable Temporary Auto Post-Fault Wakeup mode in Remote-NR button. With Temporary Auto mode disabled and the recloser in R-NR mode, the recloser will use the NR Curve settings instead. See Figure 130.

Figure 130. Enable or disable Temporary Auto mode when the recloser is in R-NR mode.

For more information, see Appendix D, “Understanding the Active TCC Curve When the TripSaver II Recloser is in R-NR Mode” on page 106.

Gateway Drop Open Screen

The Gateway Drop Open screen is used with the S&C TripSaver II Communications Gateway to allow the TripSaver II recloser to drop open by means of a local signal from the TripSaver II Communications Gateway. It can only be used if the TripSaver II recloser has been configured using the Gateway Mode setting under the Communication  ettings screen and is connected to a TripSaver II Communications Gateway, and if the appropriate settings for Gateway Drop Open mode are configured in the  communications gateway.
See S&C Instruction Sheet 461-509, “TripSaver® II Communications Via Gateway:
Installation, Operation, and Configuration,” for more details on configuring the TripSaver II recloser to work in Gateway Drop Open mode.
When the service center configuration software is connected to the TripSaver II recloser via the USB transceiver and power module, the status of the TripSaver II recloser’s Gateway Drop Open configuration will appear in the Gateway Drop Open Settings screen when the software is in the Connected mode. See Figure 131.

Figure 131. The Gateway Drop Open Settings screen, when connected via USB transceiver.

When connected to the service center configuration software via the communications gateway instead of the USB transceiver and power module, Disable and Enable buttons will be visible. The Gateway Drop Open feature can be enabled or disabled using these buttons. See Figure 132.
Note: Disabling or enabling the Gateway Drop Open feature in the service center configuration software’s Gateway Drop Open Settings screen will disable or enable the  recloser’s Gateway Drop Open mode in the communications gateway. See S&C Instruction Sheet 461-509, “TripSaver® II Communications Via Gateway: Installation, Operation, and Configuration,” for more information.

Figure 132. The Gateway Drop Open Settings screen, when connected via communications gateway.

DNP Remote Drop Open Screen

The Remote Drop Open feature is only available for TripSaver II reclosers supplied with the Extended Open Interval option (“-O”) and firmware versions 1.9 and 1.8 and for reclosers that have also been ordered with the Remote Drop Open option (“-D”) factory-enabled. The TripSaver II recloser must be properly paired with an S&C TripSaver II Communications Gateway, and it must be properly configured to accept a Drop Open command in response to a DNP3 command received via the connected SCADA transceiver. Note: The DNP Remote Drop Open screen is also used when the communications gateway has been set to use the IEC104 protocol. For detailed instructions for proper configuration of the Remote Drop Open feature in the TripSaver II recloser and the communication gateway, see S&C Instruction Sheet 461-509, “TripSaver® II Communications via Gateway: Installation, Operation, and Configuration.”

When Connected to the Service Center Configuration Software via the USB Transceiver
When the TripSaver II Service Center Configuration Software is connected to the TripSaver II recloser via the USB transceiver and power module, the status of the TripSaver  II recloser’s Remote Drop Open configuration will appear in the DNP Remote Drop Open screen when the software is in Connected mode. See Figure 133.

Figure 133. The DNP Remote Drop Open screen, when connected via the USB transceiver.

When Connected to the Service Center Configuration Software via the Communication Gateway
When connected to the TripSaver II Service Center Configuration Software via the TripSaver II Communications Gateway instead of the USB transceiver, the Disable and Enable buttons will be visible. The DNP Remote Drop Open feature can be enabled or disabled using these buttons. See Figure 134.
Note: Disabling or enabling the DNP Remote Drop Open feature from the service center configuration software’s DNP Remote Drop Open screen will disable or enable DNP Remote Drop Open mode in the communication gateway. See S&C Instruction Sheet 461-509, “TripSaver® II Communications via Gateway: Installation, Operation, and Configuration,” for more information about configuring this feature.

Troubleshooting

Optimizing Signal Strength

Having a low signal strength between the TripSaver II recloser and the USB transceiver can cause delays in updating settings and extended firmware update times. If  experiencing low signal quality when connected to a TripSaver II recloser using the USB transceiver and the service center configuration software, move the powered  TripSaver II recloser between one to 4 inches (25 to 102 mm) away from the USB transceiver, with the recloser facing down and the trunnion pointing up and with the LCD  screen toward the USB transceiver at an approximate 45˚ angle. See Figure 135.
Note: For more information on signal quality and the signal strength indicator, see the “Additional Information Bar” section on page 38.

Figure 135. Placement of the TripSaver II recloser in relation to the USB transceiver

Understanding the LED Indicators on the USB Transceiver
Table 1 details the USB transceiver’s LED indicators and their meaning. See Figure 136.

Figure 136. LED indicators on the USB Transceiver.

Table 1. USB Transceiver LED Indicators

during the connecting stage indicates the connection is successful and about to complete.
Red (slow-blinking)| The USB transceiver is attempting to connect to a TripSaver II recloser.
Red (Constant)| USB transceiver is in the Error state. If the red LED is on constantly, the USB transceiver should be reset. (See the “If the Connection Process Displays a Timeout Message” section on page 97 for directions on how to reset the USB transceiver.)

If Connection Process Displays a Timeout Message
When attempting to connect a TripSaver II recloser using the service center configuration software, the connection process will timeout if it is unable to create or maintain a wireless connection. This is generally caused by low signal strength, which can be a result of distance, orientation of the product, interference from other signal sources, or a combination of these. See Figure 137.

Figure 137. Timeout message.

STEP 1. Remove sources of interference. Wi-Fi and Bluetooth operate in the same 2.4-GHz frequency band as the USB transceiver (dongle). Before clicking the Retry  button, disable the computer’s Wi-Fi and Bluetooth adapters. If possible, disable nearby Wi-Fi and Bluetooth devices. If Wi-Fi is required for the laptop, if possible, disable  the 2.4-GHz band and use a 5-GHz connection. Keep any powered TripSaver II reclosers not being configured at least 30 feet (914 cm) away from the TripSaver II recloser  being configured, or power off any TripSaver II reclosers not being configured. Also power off any TripSaver II Communications Gateways near the TripSaver II recloser.
STEP 2. Optimize the TripSaver II recloser’s placement. Make sure the TripSaver II recloser is positioned as described in the “Optimizing Signal Strength” section on page 96.
STEP 3. Reattempt connecting to the TripSaver II recloser. If the Timeout message (see Figure 137) persists or an Object Error message (see Figure 138) appears, (this may  be noticeable more often when connection to consecutive TripSaver II reclosers using the same computer), reset the USB transceiver.

Figure 138. Object error message.

STEP 4. Reset the USB Transceiver.
(a) Click on the Cancel button when the error message displays.
( b) Unplug the USB transceiver. Disconnect the power module from the
TripSaver II recloser being configured and wait 15 seconds for it to completely power down.
(c) Close the Service Center Configuration Software.
(d) Plug back in the USB transceiver.
(e) Restart the Service Center Configuration Software.
(f) Re-connect the power module to the TripSaver II recloser to be configured.
(g) Re-establish communications with the TripSaver II recloser using the configuration software.
If still having connection problems, contact the Global Support and Monitoring Center at 1-888-762-1100.

Appendix D
Understanding the Active TCC Curve When the TripSaver II Recloser is in R-NR Mode
A SCADA communication can place a TripSaver II recloser with the Extended Open  Interval option (option “-O”) into Remote Non-Reclose (R-NR) mode if remote communications are enabled via the TripSaver II Communications Gateway. With the addition of the new NR-Standard, Cold Wakeup, and Post Fault Wakeup curves, and  with the ability to turn off the Temporary Auto mode, the TripSaver II recloser may behave differently from what is expected.
Table 4 explains which curve is active depending on the MODE-SELECTOR lever position, the R-NR mode, the conditions the recloser is “waking up” from when being closed into its mounting, and whether the Temporary Auto mode has been disabled under the R-NR Functions menu.
