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.

(Attention, observe the documentation!)
Warning of an electrical hazard
Intended use
- Measurement of current, voltage, power and frequency in the specified measuring ranges.
- Indoor use non condensing, non corrosive.
- Mounting on DIN rail or screwing on.
- Failure to comply with these instructions will void all guarantee and warranty.
Description
Depending on type the measurement modes analogue signal (2×) 0/2 to 10 V
and/or (2×) 0/4 to 20 mA AC/DC are supported. As individually adjustable
threshold values are reached, two galvanically isolated alarm outputs enable
the device to perform switch-on or switch-off operations.
Using the configuration software “Digalox® Manager” the device can be
configured, e.g. thresholds for alarm output, hysteresis, and more.
Depending on the model, measured values can be transmitted via XBEE radio
technology or RS485 Modbus interface. In addition, the device features a
counting function with data retention. This enables operating-hours-counters
or time-counters for exceeding and falling below threshold values, as well as
single pulse counting (MPP) or double pulse counting (MPPV). The device can be
mounted on DIN rails as well as on other backgrounds through corresponding
holes in the housing.

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.
Please note that the display value selected in “Digalox® Manager” is active in
the device only until the power supply is interrupted.
In further operation, the first four display values are provided or the one selected via connections J4-J6 and the three following display values.
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.
