Installation and start-up

If this is the first time you are configuring the instrument, below are the steps to follow during a first installation. Read all the manual sections to have a full and clear view of the characteristics of the instrument. Do not forget to read the installation precautions in section 17.

1. Install the instrument at the DIN rail
2. Read how to operate the instrument (see section 10)
3. Connect the input, the output and the power terminals (see section 9).
4. Configure the input and output signals
   • and choose a predefined configuration code (see section 8)
   • introduce the code at the instrument (see section 13.1)
5. If needed, customize the input and output signal ranges (see section 13.4)
6. If needed, configure the display reading (see section 13.5), the key ‘UP’ ( ) ‘force’ menu (see section 13.6), and the key ‘LE’ ( ) ‘messages’ function (see section 13.7),
7. If needed, block access to the ‘configuration menu’ (see section 13.8)

Typical applications

To measure electrical signals in AC and DC and provide a standard process signal in 4/20 mA or 0/10 Vdc. Accepts signals from current shunts, signals from DC batteries of 12 Vdc, 24 Vdc, 48 Vdc, …, signals from tachometric dynamos of ±60 Vdc, power lines of 230 Vac, 115 Vac, 48 Vac, 24 Vdc, AC leak currents of down to 5 mAac and below, 50 and 60 Hz frequency signals from AC power lines, signals from X/5 and X/1 current transformers.

SOS mode

The instrument includes a configurable ‘SOS mode’ function that provides a way to manually configure a fixed output signal. This output signal remains fixed, independent of the input signal value or sensor state. This function allows to perform urgent maintenance or repair tasks at the input section of the system, for example replacing sensors, shunts, or deactivating power lines, while the instrument still provides a controlled signal that allows for the process to continue its activity, under human surveillance. When the maintenance or repair task has been performed, the instrument can be taken back to the standard working mode, where the output signal is proportional to the input.

When manually activated, the ‘SOS mode’ generates the output signal configured, and the front display remains flashing with the message ‘SoS’. All other systems are disabled, which means that:

• no error messages will be shown on the display
• no key ‘UP’ ( ) ‘fast access’ menu is accessible
• no key ‘LE’ ( ) ‘messages’ function is accessible
• no ‘Eco’ mode activates

Only key ‘SQ’ ( ) is accessible, to access the ‘configuration menu’ (eventually this access can be password locked) to deactivate the ‘SOS mode’. Deactivation of ‘SOS mode’ must be performed manually by configuring the function to ‘oFF’.

To configure the ‘SOS mode’ function, see section 13.8.

Messages

The instrument includes a configurable ‘messages’ function that provides advanced system information on the display, available to the operator with a single click at the front key ‘LE’ ( ). This information is helpful during start-up, installation, system verification, routine maintenance and troubleshooting, as messages and values provide information on the actual input and output signal value, and the actual percentage of the input signal compared to the full-scale and scaled process values.

This information is available at any time and is displayed sequentially when requested. Access to this information reduces maintenance time, improves time invested in failure location, and helps for an easy resolution of the problem. Additionally, each instrument can be assigned a custom label code of up to 8 characters (see Table 1), that can be displayed at the front display or the messages sequence, making system identification of each instrument an easy task.

To configure the ‘messages’ function, see section 13.7.

Table 1 | Available label codes (‘Label’ parameter)

Labelling examples (‘Label’ parameter): for an application with multiple engine control, where voltage and frequency are being measured for three engines, and converted to 4/20 mA for retransmission to PLC or SCADA. Six DR- I4E converters are being used, to measure 0/300 Vac and 45/55 Hz. Each DR-I4E can be configured with the following label for easy identification:

• Label for engine 1 frequency measurement: Eng1.hZ
• Label for engine 2 frequency measurement: Eng2.hZ
• Label for engine 3 frequency measurement: Eng3.hZ
• Label for engine 1 voltage measurement: Eng1.Vac
• Label for engine 2 voltage measurement: Eng2.Vac
• Label for engine 3 voltage measurement: Eng3.Vac

How to operate the instrument

Configuration system
The instrument is fully configurable from the 3 push button keypad and the 4 red digit LED display at the front of the instrument (see Table 5).

Table 5 | CONFIGURATION SYSTEM

‘Normal mode’ of operation

AT POWER-UP
When the power supply is connected, the instrument applies the following sequence:

• the ‘display’ shows the firmware code ‘A6.xx’.
• the ‘display’ shows the configured ‘units’ and ‘input range’ (for example: ‘Vac’ and ‘600V’).
• the instrument is now in ‘normal mode’ of operation and the ‘display’ shows the ‘information’ configured in section 13.5.

FROM ‘NORMAL MODE’ OF OPERATION
From the ‘normal mode’ of operation, the operator can access the following functions:

• key ‘SQ’ ( ) gives access to the ‘configuration menu’ (see section 10.3).
• key ‘UP’ ( ) gives access to the ‘force’ menu (see section 10.4).
• key ‘LE’ ( ) activates the ‘messages’ function (see section 10.5).

‘ECO’ FUNCTION (‘DISPLAY’ POWERED OFF)
The ‘Eco’ function powers off the display under the following conditions:

• the instrument is in ‘normal mode’ of operation.
• there is no interaction from the operator for 60 seconds.

The decimal point remains active (flashing), indicating that the instrument is working correctly. This is a configurable function, enabled by default. To configure the ‘Eco’ function, see section 13.8.

How to operate the ‘Configuration menu’

HOW TO ENTER THE ‘CONFIGURATION MENU’
With the instrument in ‘normal mode’ of operation (see section 10.2), press the ‘SQ’ ( ) key and maintain for 1 second. The horizontal leds light from bottom to top. When the upper LED lights, the instrument enters into the ‘configuration menu’.

When entering the ‘configuration menu’, the first menu entry ‘Function code’ (codE) is displayed. See section 14 for a full view of the ‘configuration menu’.

• If the ‘SQ’ ( ) key is released before entering into the ‘configuration menu’, the horizontal leds light downwards from top to bottom, and the instrument returns to ‘normal mode’ of operation.

HOW TO OPERATE INSIDE THE ‘CONFIGURATION MENU’
Inside the ‘configuration menu’, use the front keypad to move through menu entries, and parameters, and select configuration values:

• Key ‘SQ’ ( ) functions as the ‘ENTER’ key. It selects the menu entry currently displayed. At numerical value entries, it validates the number displayed.
• Key ‘UP’ ( ) moves vertically through the different menu entries. At numerical value entries, it modifies the selected digit by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
• Key ‘LE’ ( ) functions as the ‘ESCAPE’ key. It leaves the selected menu entry, and eventually, will leave the ‘configuration menu’. When leaving the ‘configuration menu’, the changed parameters are activated. At numerical value entries, the ‘LE’ ( ) key allows to selection of the active digit. To modify a numeric value press the ‘UP’ ( ) key to increase the value ‘+1’. Press the ‘SQ’ ( ) key to validate the value.

WHEN EXITING THE ‘CONFIGURATION MENU’

• When exiting the ‘configuration menu’ without changes (either by ‘rollback’ activation or because there are no changes in the configuration), the horizontal leds light down from top to bottom, and the instrument returns to ‘normal mode’ of operation.
• When exiting the ‘configuration menu’ with changes, the display leds light a round shape while the new configuration is stored. When the round shape is finished, a start-up is applied (see section 10.2). After start-up, the new configuration is active and the instrument is in ‘normal mode’ of operation.

‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 60 seconds, the instrument exits the ‘configuration menu’ discarding changes, and returns to ‘normal mode’ of operation.

• When the operator is inside the ‘configuration menu’, the output signal will remain overranged at the maximum signal. Additional configurations are available at the ‘On error’ parameter (see section 13.8).
• When the operator exits the ‘configuration menu’, the output signal is temporarily set to the minimum value for a time <5 seconds, while the instrument restarts.

How to operate the ‘Force’ menu

HOW TO ENTER THE ‘FORCE’ MENU

• With the instrument in ‘normal mode’ of operation (see section 10.2), press and hold the ‘UP’ ( ) key for 1 second. The horizontal leds light from bottom to top. When the upper LED lights, the instrument enters into the ‘force’ menu.
• If the ‘UP’ ( ) key is released before entering into the ‘force’ menu, the horizontal leds light downwards from top to bottom, and the instrument returns to ‘normal mode’ of operation.

HOW TO OPERATE INSIDE THE ‘FORCE’ MENU
The available functions inside the ‘force’ menu can be configured (see section 13.6). By default, ‘Force High’, ‘Force Low’ and ‘Force Set’ are available. Inside the ‘force’ menu:

• press the ‘UP’ ( ) key to move to the next function.
• press the ‘SQ’ ( ) key to activate the selected function.

When the function is active, the display will remain flashing. Press the ‘SQ’ ( ) key to deactivate the function (display stops flashing), or wait for the rollback to activate.

Table 7 | Example of ‘Force’ menu with all functions set to ‘on’

See section 13.6 for a list and a description of available functions.

DESCRIPTION OF ‘FORCE’ FUNCTIONS

• The ‘force’ functions allow to manually force the output signal to the low and high levels of the output signal selected. These functions allow us to easily validate the correct function of remote elements connected to the instrument output, such as PLC, HMIs, SCADAs, etc.
• The ‘force low’ function sets the output signal to the minimum value of the selected range (4 mA or 0 Vdc or the value configured at the ‘output_ low’ parameter).
• The ‘force high’ function sets the output signal to the maximum value of the selected range (20 mA or 10 Vdc or the value configured at the ‘output_high’ parameter).
• The ‘force set’ function sets the output signal to a value between 0 and 100% of the maximum selected range (4 to 20 mA or 0 to 10 Vdc or the range configured at the ‘output_low’ and ‘output_high’ parameters).
• When entering the ‘force set’ function, the display reads ‘50’ (the output is forced to 50% of the configured range). Use keys ‘UP’ ( ) and ‘LE’ ( ) to move up to 100% or down to 0% of the configured range.

HOW TO EXIT ‘FORCE’ MENU
To exit the ‘force’ menu, press the ‘LE’ ( ) key, or press the key ‘UP’ ( ) key until the parameter ‘—’ appears, and select by pressing the ‘SQ’ ( ) key, or wait without pressing any key until the automatic ‘rollback’ activates.

When exiting the ‘force’ menu, the horizontal leds light down from top to bottom, and the instrument returns to ‘normal mode’ of operation.

‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 60 seconds, the instrument exits the ‘force’ menu and returns to the ‘normal mode’ of operation.

How to activate the ‘Messages’ function

HOW TO ACTIVATE ‘MESSAGES’ FUNCTION

• With the instrument in ‘normal mode’ of operation (see section 10.2), press the ‘LE’ ( ) key to activate the ‘messages’ function. The ‘messages’ function displays information about the instrument. The information available is configurable (see section 13.7).
• The ‘messages’ function ends when all the information has been displayed or the front keys ‘UP’ ( ) or ‘SQ’ ( ) are pressed. The ‘display’ returns to the ‘normal mode’ of operation.

Fast and advanced configurations

FAST CONFIGURATION

• The fastest way to configure the instrument is to activate one of the predefined configuration codes (see section 8).
• Access the ‘configuration menu’ and enter the ‘Function code’ (codE) menu entry. The code displayed is the current active input-output range. Select the new code and validate. Selecting a code automatically exits the ‘configuration menu’ and activates the new configuration.
  • *There are different codes for 4/20 mA and 0/10 Vdc output signals.

To customize the input and output signals, see the ‘Advanced scaling’ section of the ‘configuration menu’ (see section 13.4).

ADVANCED CONFIGURATION
Additional configuration parameters are available in the ‘configuration menu’. The operator can customize the input and output signal ranges, the message seen on display, the functions available at the ‘force’ menu, the messages associated with the ‘LE’ ( ) key, activate filters, password function, etc.

See section 13 for a detailed explanation of the ‘configuration menu’.

Configuration menu

Function codes

• The fastest way to configure the instrument is to select a predefined configuration code (see Table 2). At the ‘Configuration code’ (codE) parameter use keys ‘UP’ ( ) and ‘LE’ ( ) to move up and down through the list of codes. Locate the desired code, and press ‘SQ’ ( ). The instrument shows the ‘codE’ parameter. Press ‘LE’ ( ) to exit the ‘configuration menu’. The instrument stores the new configuration, applies a ‘power-up’ routine and returns to the ‘normal mode’ of operation (see section 10.2).
• Selecting a ‘reserved’ code or ‘—’ returns to the previous menu without changes.
• When entering the ‘Function code’ (codE) parameter, the active ‘configuration code’ is displayed. If the actual configuration does not match any of the configuration codes, code ‘uSEr’ is displayed.
• There are different codes for 4/20 mA output (codes from 010 to 099) and 0/10 Vdc output (codes from 110 to 199) (see section 8).
• Bipolar voltage and bipolar current inputs can be configured at the ‘Advanced scaling’ section of the ‘configuration menu’ (see section 13.4).

Input range
At the ‘Input range’ (InP) menu entry select the input signal range to activate.

If you have already selected a configuration code (see section 13.1), the input range has been already selected and there is no need to manually configure again at the ‘Input range’ (InP) menu entry.

Enter the ‘AC voltages’ (VAc) parameter for a list of voltage AC input ranges, ‘DC voltages’ (Vdc) for a list of voltage DC input ranges, ‘AC currents’ (AAc) for a list of AC current input ranges, ‘DC currents’ (Adc) for a list of DC current input ranges, ‘Frequency Vac’ (Frq.V) for AC voltage frequency or ‘Frequency Aac’ (Frq.A) for AC current frequency measurement.

• AC voltage ranges available are 600 Vac, 300 Vac, 150 Vac, 60 Vac, 30 Vac, 2 Vac, 1 Vac, 500 mVac, 300 mVac and 200 mVac.
• DC voltage ranges available are 600 Vdc, 300 Vdc, 150 Vdc, 60 Vdc, 30 Vdc, 2 Vdc, 1 Vdc, 500 mVdc, 300 mVdc and 200 mVdc.
• AC current ranges available are 5 Aac, 2 Aac, 500 mAac, 75 mAac, 50 mAac, 20 mAac, 10 mAac and 5 mAac.
• DC current ranges available are 5 Adc, 2 Adc, 500 mAdc, 75 mAdc, 50 mAdc, 20 mAdc, 10 mAdc and 5 mAdc.
• frequency from AC voltages. Single range up to 100 Hz. Measured from the AC voltage signal.
• frequency from AC currents. Single range up to 100 Hz. Measured from the AC current signal.

Input signal ranges are also accessible as predefined ‘configuration codes’ (see Table 2). The predefined ‘configuration codes’ include some additional input - output ranges that are not available at the ‘Input range’ (InP) list of ranges.

All DC input ranges activate the unipolar range by default.

Example:
select the ‘60 Vdc’ input range activates the ‘0/60 Vdc=4/20 mA’ or ‘0/60 Vdc=0/10 Vdc’ configuration. To customize to a smaller range (for example 0/45 Vdc) or a bipolar range (for example ±45 Vdc) see section 13.4. To manually select the output signal see section 13.3. To customize the output range for a smaller range (for example±45 Vdc=6/15 mA or ±45 Vdc=1/5 Vdc) see section 13.4.

Output range

• At the ‘Output range’ (out) menu entry, select the output signal range to 4/20 mA (value ‘420’) or to 0/10 Vdc (value ‘010’).
• The output signal range selected can be later customized to operate in a reduced range of signals (see section 13.4).

Advanced scaling
At the ‘Advanced scaling’ (Ad.S c) menu, the input and output signal ranges can be customized. The parameters inside this menu represent the real input and output signal ranges configured at the instrument. When selecting a predefined configuration code, these parameters are configured according to the code selected. The parameters listed below, are accessible for manual configuration:

• at the ‘Input low signal’ (In. Lo) parameter configure the low input signal value.
• at the ‘Input high signal’ (In.hI) parameter configure the high input signal value.
• at the ‘Output low signal’ (ou. Lo) parameter configure the low output signal value.
• at the ‘Output high signal’ (ou.hI ) parameter configure the high output signal value.

These four parameters define the relation between the input and the output signal (see Table 19) and can be modified independently, to match the specific input-output relation for your application (see Table 20).

Table 19 | EXAMPLE FOR CODE ‘034’ (0/300 VDC=4/20 mA)

Selecting the predefined code ‘034’ configures a range of 0/300 Vdc=4/20 mA, and the values configured are as indicated below:

Additionally, a process value can be scaled using the last three parameters of the ‘Advanced Scaling’ (Ad. Sc) menu entry. The scaled process value can be accessed through the ‘display information’ function (see section 13.5) or the ‘messages’ function (see section 13.7).

• at the ‘Process low’ (Pr. Lo) parameter, configure the process value associated with the low input signal value.
• at the ‘Process high’ (Pr.hI) parameter, configure the process value associated with the high input signal value.
• at the ‘Process decimal point’ (Pr.dP) parameter, configure the decimal point position for the process value.

Example:
a 0/60 mVdc signal from a shunt is associated with a 0/150.0 Adc process value. Configure the process value to ‘0’ and ‘150.0’ (‘Process low’ = ‘0’, ‘Process high’=‘1500’, ‘Process decimal point’=’xxx.x’).

Table 20 | EXAMPLE FOR BIPOLAR RANGE

To configure a ±45 Vdc=1/9 Vdc application, select code 137 (0/60 Vdc=0/10 Vdc) and then configure the parameters below:

Display information

At the ‘Display information’ (dISP) menu select one parameter to read on display when the instrument is in ‘normal mode’ of operation. If you need access to more than one information, see the ‘messages’ function (see section 13.7) associated with the front key ‘LE’ ( ).

• select ‘Input signal value’ (InP.S) to read the input signal value and the measurement units (for example: ‘Inp Vdc 28.5’).
• select ‘Output signal value’ (out.S) to read the output signal value and the measurement units (for example: ‘Out mA 12.40’).
• select ‘Label’ (LAbL) to read the value configured at the ‘label’ parameter (see section 13.8).
• select ‘Process value’ (Proc) to read the process value as scaled at the process parameters (see section 13.4) (for example: ‘Proc 1500’).
• select ‘Percentage’ (Prct) to read the percentage of signal, where ‘0’ is the value assigned to the ‘input signal low’ parameter, and ‘100’ is the value assigned to the ‘input signal high’ parameter (see section 13.4) (for example: ‘Prct 23.5’).

Key ‘UP’ (‘force’ menu)
The key ‘UP’ ( ) at the front of the instrument gives access to a configurable list of functions (see section 10.4).

At the ‘Key UP (‘force’ menu)’ (K.uP) menu select which functions will be available when pressing the front key ‘UP’ ( ). Select ‘on’ to activate the desired functions.

• configure ‘Force Low’ (F.Lo) to ‘on’ to activate the ‘Force low’ function menu entry.
• configure ‘Force High’ (F.hI) to ‘on’ to activate the ‘Force high’ function menu entry.
• configure ‘Force Set’ (F.SEt) to ‘on’ to activate the ‘Force set’ function menu entry.

The functions configured to ‘on’ are available in the ‘force’ menu. See section 10.4 for a description of each function and how to operate them.

Key ‘LE’ (‘messages’ function)
The key ‘LE’ ( ) at the front of the instrument gives access to a configurable set of information messages.

At the ‘Key LE (messages function)’ (K.LE) menu, select the information to be displayed when the front key ‘LE’ ( ) is pressed (see section 10.5). Select ‘on’ to activate each information.

• configure ‘Input signal value’ (InP.S) to ‘on’ to see the actual input signal value and units (for example: ‘Inp Vac 48.7’)
• configure ‘Output signal value’ (out.S) to ‘on’ to see the actual output signal value and units (for example: ‘Out mA 08.3’)
• configure ‘Label’ (LAbL) to ‘on’ to read the value configured at the ‘label’ parameter (see section 13.8).
• configure ‘Process value’ (Proc) to ‘on’ to read the process value as configured at the process parameters (see section 13.4) (for example: ‘Proc 1500’).
• configure ‘Percentage’ (Prct) to ‘on’ to see the actual percentage of signal, where ‘0’ is the value assigned to the ‘input signal low’ parameter, and ‘100’ is the value assigned to the ‘input signal high’ parameter (see section 13.4) (for example: ‘Prct 23.5’).

When more than one parameter is set to ‘on’, values will be displayed sequentially, in the same order as they are listed in the menu, with a middle dash ‘-’ between them. When all information has been displayed, the instrument returns to the ‘normal mode’ of operation.

‘Tools’ menu
The ‘Tools’ (tool) menu groups several functions.

• at the ‘Eco mode’ (Eco) parameter, define the time to wait before the display is powered off (while in ‘normal mode’ of operation). The default value is 60 seconds. Configure ‘0’ to disable the function and maintain the display always on.

• at the ‘SOS mode’ (SoS) parameter select ‘on’ to activate the output signal to a predefined value. Select the value from 0 to 100% of the active output range (4/20 mA or 0/10 Vdc). To deactivate the ‘SOS mode’ select ‘oFF’. See section 6 for more information on the ‘SOS mode’.

• at the ‘Label’ (LAbL) parameter, define an alphanumerical value to be displayed on the display, when the instrument is in ‘normal mode’ of operation, or at the ‘messages’ function when the key ‘LE’ (3) is pressed. The label can be used to identify the instrument with its internal factory code. If more than four characters are needed, configure the ‘Label 2’ (LbL.2) parameter. The total label value is the characters at ‘label’ followed by the characters at ‘label2’. For additional information and a list of available characters, see section 7.

• at the ‘On error’ (on. Er) parameter, configure the behaviour of the output signal, in case of hardware error at the input (see section 16).

• select ‘Output to high’ (to. hI) to force the output signal to over range to maximum value

• select ‘Output to low’ (to. Lo) to force the output signal to under range to minimum value

• select ‘Standard output’ (Stdr) to over range output signal to the maximum value in case of the input signal over range, and to under range output signal to the minimum value in case of input signal ununder range at the ‘On ‘SQ’’ (on. Sq) parameter, configure the behaviour of the output signal when the operator is inside ‘configuration menu’ (see section 10.3).

• • select ‘Output to high’ (to.hI) to force the output signal to overrange to maximum value
  • select ‘Output to low’ (to.Lo) to force the output signal to underrange to minimum value

• select ‘Hold output’ (hoLd) to hold the output signal while the operator remains inside ‘configuration menu’.

• at the ‘Power filter’ (P.FLt) parameter, select a filter for specific power frequency rejection. The filter selection has an effect on the response times (see section 12). Applies only to DC signal ranges. AC signal ranges automatically configure this parameter to ‘50 and 60 Hz filter’ and this value can not be changed.

  • select ‘No filter’ (nonE) to disable frequency rejection filters. This enables the fastest response time.
  • select ‘50 Hz filter’ (50.hZ) to enable rejection to 50 Hz frequency.
  • select ‘60 Hz filter’ (60.hZ) to enable rejection to 60 Hz frequency.
  • select ‘50 and 60 Hz filter’ (both) to enable rejection to both 50 Hz and 60 Hz frequencies. This is the slowest response time.

• at the ‘Average filter’ (AVr) parameter, configure the recursive filter to be applied to measured input signal. The filter can be used to reduce oscillations on noisy signals. Configure the filter strength between ‘0’ and ‘100’. The filter is stronger with higher values. Increasing the strength of the filter slows the response speed of the instrument. Value ‘0’ disables the filter.

• at the ‘Dead band’ (d.bnd) parameter set a value between ‘0.0’ % and ‘100.0’ %. This is a percentage of the ‘input signal high’ parameter configured at the ‘Advanced scaling’ section. Input signals below this value, are treated as a ‘0’. This parameter applies to all measuring ranges. For bipolar ranges, the dead-band is bipolar and centered at ‘0’.
  example : instrument configured with code ‘012’ (0/300 Vac = 4/20 mA) and ‘input signal high’ parameter modified to 250 Vac for an effective input – output relation of ‘0/250 Vac = 4/20 mA’. Configure the ‘Dead band’ parameter to ‘1.0’ to set a dead band value of 2.5 Vac. All signals below 2.5 Vac will be treated as 0 Vac, and the output will be 4 mA.

• the ‘Version’ (VEr) parameter informs about the firmware version running in the instrument.

• at the ‘Password’ (PASS) parameter define a 4 digit code to block access to the ‘configuration menu’. Activate the password to prevent access to the instrument configuration by non authorized personnel. To activate the ‘Password’ function select ‘on’, enter the code and validate. The password will be requested when entering the ‘configuration menu’. The password does not block access to the ‘force’ menu. To deactivate the password, set the password parameter to ‘oFF’.

• at the ‘Factory reset’ (FAct) parameter select ‘yes’ to activate the default factory configuration (see section 15 for a list of factory default parameters).
