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, 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.
In the “Downloads” area of www.digalox.com you can find the latest version of the instruction manual and the software “Digalox® Manager”.

Product overview

1. 2 optocoupler switch outputs
2. Jumper pins J1–J12
3. Supply voltage input
4. Interface (XBEE / RS485)

Configuration

Connect the device to a computer:
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 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.
