Safety instructions

• Read instruction manual carefully before operating the device! Keep for later reference.
• Mounting and installation must be carried out by suitably qualified and competent persons only.
• When working on the device hazardous voltages must not be connected to the device! The terminals J1-J12 are not isolated from the measuring circuit.
• The device must not be used as the only protective device or protective shutdown.
• The device is not intended to protect persons or facilities against harm. Specific devices must be used to guarantee safety (protection relays, cut-off switches, etc.).
• When connecting switches to the terminals J1-J8, only switches must be used whose isolation voltage is at least twice the maximum occurring measurement voltage. For example, when measuring 30 V DC switches must be isolated for at least 60 V.
• Do not open the housing!
• Do not use the device in the presence of explosive or flammable substances!
• All cables carrying hazardous voltages must be secured with external separators.

Meaning of symbols

General warning sign (Attention, observe the documentation!)
Warning of an electrical hazard

Intended use

• Measurement of current and voltage in the specified measuring ranges for process signals
• Indoor use non condensing, non corrosive.
• Panel mounting.
• In operation, supply the device preferably via screw terminals with 12 to 24 V AC/DC instead of via USB.
• Failure to comply with these instructions will void all guarantee and warranty.

Description

The measurement types analogue signal 0/2 to 10 V and 0/4 to 20 mA DC are supported. The multi display with RGB backlight is able to display up to four parameters simultaneously. Thresholds can be associated with individual warning colours. The unit can be switched between display values via an external switch.
Minimum and maximum values are recorded and can be displayed and reset via jumper or an external switch. Measured values are recorded over a timespan of 36 seconds up to 14 days. The time base as well as the display of the measuring history can be switched by an external switch. The measured values remain stored as long as the device is supplied with voltage.
The following parameters can be adjusted using the configuration software “Digalox® Manager”: scale endpoint, scale caption, display style (pointer, tachometer, bar graph, and more), splash image, backlight colour, thresholds for alarm output, threshold warning colour (light, blink), hysteresis, and more. Recorded measurement values can be read and a continuous transmission of the actual measuring value can be enabled. Using the software, values can be viewed and exported as CSV. Depending on the model, measured values can be transmitted via USB, XBEE radio technology or RS485 Modbus interface. In addition, the devices feature a counting function with data retention. This enables operating-hourscounters or time-counters for exceeding and falling below threshold values, as well as single pulse counting.
In the “Downloads” area of www.digalox.com you can find the latest version of the instruction manual and the software “Digalox® Manager”.

Mounting

Carefully insert the device into the panel cut-out. Insert the mounting bracket from the back and push towards the panel until the device sits tight. Make sure the mounting bracket is snapped into the side of the housing. To ensure IP65 protection (dust and water jet) when mounting in a front panel, use optional gasket (separately available).

Electrical connections

Legend
Voltage source, e.g. active sensor or sensor with voltage supply
Current source, e.g. active sensor or sensor with voltage supply
WARNING: The device may only be operated in one of the connection options shown above! Use an ultra-fast-acting fuse (FF) at the current measurement input.
If two sensors are used, both must be active. If one sensor is inactive, there must not be anything connected to the corresponding low measuring input, otherwise incorrect values will be measured.

Configuration

Connect the device to a computer:

| USB: Connect the device and the computer using a USB cable. The device driver is installed automatically if the computer is connected to the Internet.
---|---
| XBEE: Insert the XBEE stick into the computer. The device driver is installed automatically if the computer is connected to the Internet. In order to reset the XBEE settings, short-circuit terminal J8.
| RS485: Short-circuit  terminal  J8.  Disconnect  the  device  from  the Modbus network and connect it to the computer using an RS485 USB adapter. After completing the configuration, open J8 again.

Start the “Digalox® Manager” software and connect it to the device. Settings can then be made on the various tabs and saved in the device.
After restart, the device always shows the first display value or the one that is selected by the jumpers J4-J6 (see table “display value”),
in case of a multi display style additionally the following display values.
Table display value (factory preset, can be changed by software)

| Display value| Display| Selection
---|---|---|---
1| 10 V DC scaled| 10 V % J1|
2| 2-10 V DC scaled| 2-10 V %|
3| 20 mA DC scaled| 20 mA %|
4| 4-20 mA DC scaled| 4-20 mA %|

Other settings

The following functions can be activated independently during operation by short-circuiting connectors J1-J3, e.g. using a jumper or switch:

| J1: Graphical historic data display
The unit  displays the stored values within the set time base as a graphical trend. The time  base  can  be  set  to  days  (7,  14), hours (1, 3, 6, 12, 24, 48, 72), minutes (3, 15, 30) or seconds (36).
The  time  base  can  be  changed  by alternately opening and closing J1 (interval < 2 sec). When first opening and closing J1 the current time base is displayed. For each subsequent opening and closing the time base changes to the next setting. In order to save the setting permanently, the software “Digalox®  Manager” has to be used.
---|---
| J2: Min-Max display
The  display  shows  the  maximum  and minimum  values  recorded  since  the last reset. The values can be reset by opening and closing connection J2 shortly (interval < 2 sec). The display shows “Minmax reset”.
| J3: Auto-scaling
The device automatically changes the upper scale  caption  depending  on  the current measuring value, e.g. between 10, 100 and the set upper scale caption.

Maintenance

Periodically check all external cable connections.

Cleaning

Observe the safety instructions before cleaning the device. Clean the device with a dry lint-free soft cloth. Do not use solvents.
