Overview

Thank you for your purchase of the MC Miller JPL100 Interrupter. To get the most of the JPL100’s functionality please read through this manual and make sure to store this manual somewhere where others who use the JPL100 can read it.

Getting to know the JPL100

1. GPS Antenna Connector (SMA)
2. Power Button
3. Power Status LED
4. Sync Jack
5. PE Jack
6. Latch Button
7. Relay Status LED

The JPL100 has a simple front panel interface for quick and easy operation. Elements of the front panel and its functionality are listed below:

1. GPS Antenna Connector – SMA connector for attaching a GPS antenna.
2. Power Button – Power On/Off the JPL100.
3. Power LED – Power LED has multiple purposes. During normal operation it can be in two different modes.
   • a. When the power LED is pulsing every second, it states that the GPS module within the JPL100 is on and is gathering GPS data. If the LED is  flashing every 5 seconds the GPS within the JPL100 is turned off and indicates that GPS data has previously been acquired.
   • b. When the power LED is flashing very rapidly, the JPL100 is detecting an overheat event. Please stop using the interrupter immediately and contact MC Miller support team if an overheat event were to happen.
4.  Sync Jack – The Sync Jack is used for connecting to other MC Miller Interrupters for synchronizing of interrupting cycles.
5. PE – Protective Earth (only connect to Rectifier case).
6. Latch Button – Activates the latch function.
7. Relay State LED – Relay state LED shows if the interrupter is cycling and will do so by flashing the LED at the start of the On cycle. When the output is latched, The LED will stay solid for 4 minutes and then blink synchronized to the power LED.

Basic Operation

Turning on the JPL100

To turn on the JPL100, push the power button on the front panel. After the power button is pressed the power LED will stay solid for 5 seconds then flashes to indicate that the JPL100 is running properly.

Connecting to JPL100

Do not attempt to connect to the interrupters with multiple Android devices at the same time

In order to connect to the JPL100 with an Android device, open the application on your device. The device will turn on Bluetooth service and automatically scan for nearby MC Miller Interrupters. At the time of writing this manual, the application supports TH100A  and JPL100 interrupters.

During initial startup, a prompt will pop up asking for Bluetooth and Location service. Please authorize these permissions so the application can work properly.

The application will populate the list with nearby MC Miller Interrupters while it is scanning for nearby devices. Each selection shows the Interrupters name and Interrupters Serial Number. To connect to the chosen interrupter, simply tap the selected device on the application and the application will attempt to connect to  the device.

Setting the Parameters

All JPL100s come with a set of default settings shown below. All settings can be adjusted to meet the user’s requirement.

In order to change any of the settings for the connected interrupter the user must first activate edit mode on the tablet by pressing the “Edit” button on the application. This will activate the edit mode where all parameters can be changed

Changing Start/End Date

In order to change the start or end date, edit mode must be activated. To change the start date and/or end date tap on the date on the application. A calendar like the one shown below will pop up for the user to select the start/end date of your interrupting cycles. The user can also change months by swiping the calendar.

Start/End Time

The time that is shown on the parameters are adjusted to the Android device’s local time. For instance, MC Miller is in Eastern Standard Time (UTC-5) therefore the application will show “EST” at the end of the text field.

To set a new time, activate edit mode and enter the time you want to start/end the interruption cycle according to the local time zone the Android device is set for.

If Start Date/Time and End Date/Time are set the same, the interrupter will run continuously.

On/Off Cycle

The On/Off cycle setting determines On and Off cycles of the interrupter. The setting can be changed by the user through the application and will have to enter the cycle in milliseconds. For example, if an on cycle of 2 second and off cycle of 3 second are required, the user will have to change the on cycle setting to 2000 and off cycle  setting to 3000. The range of the On/Off cycle ranges from 50 milliseconds to 65,535
milliseconds.

Do not set On/Off Cycle under 50 milliseconds.

1 second = 1000 millisecond

Relay Delay

The relay delay field enables the user to control the delay of the switch. This is only use if the JPL100 is syncing to another interrupter that has a slower switch. The unit of  measure for the delay is in milliseconds. To accurately get the relay delay of the system, do an initial waveform  and calculate the difference between the rising edge of the waveform.

Night Latch

The Night Latch can be selected through the Android application. Enter edit mode by pressing the “Edit” button on the application and tapping on the night latch switch within the application. The function of the Night Latch is to latch the output to ON when the interrupter is not within its preset cycling period.

GPS Sync Period

The GPS Sync Period field enables the user to control when the JPL100 will resync its internal RTC time with the accurate UTC time coming from the GPS. The unit of measurement of this period is in minutes.

Longer period between GPS sync will lower power consumption but will cost accuracy.

Shorter period between GPS sync will increase power consumption but will be most accurate. Setting of “0” is not recommended as it will leave GPS on indefinitely.

Recommended setting: 60 minutes

Time Type

This setting lets the user decide if GPS sync is required and which relay start position the  JPL100 needs to be in. The characteristic of each selection is as follows:

• GPS on / RTC off: GPS synchronization is on and GPS Sync Period parameter determines the interval of which the JPL100 will resync to GPS. Please view “Setting the Parameters – Setting GPS Sync Period” for more detail on setting GPS sync periods.
• GPS off /RTC on: The JPL100 may take up to 12.5 minutes to get accurate time from the GPS. In the case of an accidental power down please use this setting to jump start the cycle of the JPL100. With the RTC mode turned on the JPL100 will immediately start cycling with the time that is stored within its RTC.
• You may switch GPS time after the JPL100 is cycling to capture GPS time  for later use. JPL100 will automatically re-adjust as soon as the new accurate time is available.
• Cycle on – This setting tells the JPL100 to switch from “ON to OFF” on the first cycle according to the start date/time that is set previously.
• Cycle off – This setting tells the JPL100 to switch from “OFF to ON” on the first cycle according to the start date/time that is set previously.

Days On

If interrupting is only required at certain days of the week, this setting can be used. Each button on the application represents a day of the week, starting from Sunday and ending in Saturday.

If days of the week is not required, please have them all activated.

Latch

The latch button on the front panel is to latch the output to be always closed and will override all interrupting cycle settings. The latch button is located on the front panel. When the latch button is pushed, the latch LED will stay solid for 4 minutes and then flash with in synchronization with the power LED.

Note: Do not use latch button until the GPS time has been acquired in GPS mode. Latch can be used anytime when JPL100 is in RTC mode.

Synchronizing TH100A to JPL100

Warning

If the JPL100 is connected to the rectifier, make sure the rectifier output is OFF before attempting to sync to avoid injuries to the operator and damage to the equipment.

The JPL100 can sync other interrupter units such as the TH100A which does not have GPS synchronization. In order to sync them together please follow the steps below.

1. Connect into each device via Android Application and ensure that all  devices have the same parameters. If they are not the same, please change them to  the desired setting. To make changing the parameters easier, use save and load function of the application.
2. Make sure all units are powered on and are cycling through its preset configurations.
3. Connect the devices together via a sync cable.
4. Connect to the JPL100 through the Android application.
5. Press the Sync button on the bottom of the application and it will prompt you to change the connection. Press “OK” when ready.

To make sure that the interrupters are synchronized properly, watch the latch status LED closely to make sure they blink at the same time. If the interrupters are successfully synchronized the latch LEDs on the interrupters should be synchronized  as well. If they are not synchronized, please repeat the above steps.

Synchronizing JR-1/ JR-2 to JPL100

The sync capability is also backwards compatible with older generation MCM interrupters such as the JR-1 and JR-2. In order to sync the JPL100 with the JR-1 and JR-2  please follow the steps below.

1. After the JPL100 has acquired GPS lock, configure the JPL100 to the desired  settings using the MCM Interrupter application.
2. Make sure that the JPL100 is cycling through its preset configurations.
3. Turn on the JR-1 or JR-2 and let it initialize for usage.
4. On the JR-1/ JR-2 set “START SET”, “STOP SET”, “ON CYCLE CLOSED”, and “OFF CYCLE OPEN” parameters to the same value as the JPL100. The JR-1 start relay condition must be set to ON.
5. Press “CLOCK SET” on the JR-1 and DO NOT PRESS ENTER!
6. Connect the sync cable from the JPL100 to JR-1/ JR-2. Use the sync  cable that came with the JPL100.
7. On the Android interrupter application, press Sync.
8. Make sure that the JR-1/ JR-2 display changes from “LOCh06” to “LOCh01” and will start cycling in sync with the JPL100.
9. Remove the sync cable.
10. If for any reason, the JR-1/ JR-2 is powered off, please perform the above steps again.
