Installation
The unit can be installed as follows:
•
Installation in switchgear cabinet on 35 mm mounting rail according to EN 60715 for protection against
fire, external environmental conditions and mechanical effects.
•
With screws M4 for installation on walls or panel. (additional latch is not included in delivery)
•
Connection according to connection plan or type plate.
Failure to comply with the information in this instruction manual will not guarantee the function of the device.
A circuit-breaker or switch must be situated within easy reach of the
unit and fused. Installation excess current protection should be ≤ 10 A.

Commissioning
LED Power is on = device ready for operation
LED Power flashing = parameterization mode
LED 4...20 mA flashes 3 times in parameterization mode = value accepted
LED 4...20 mA flashing = parameterisation error (with 22 mA/12 V Full-scale output outside the setting
rang, with 0 mA/0 V zero outside the setting range)
LED 4...20 mA is on = current output 4...20 mA
7.1 Parameter mode (Power LED flashing)
To enter the parameterization mode, press the button Zero for 10s when applying the control voltage until the
power LED starts to flash. To exit parameterization mode prematurely, press the Full-scale and zero buttons
at the same time. The parameterization mode is automatically exited after 10 minutes. The set values remain
stored even when the control voltage is switched off.
7.2 Adjustment zero point (0
– 40% of the adjustment range)
Set the resistance potentiometer to the desired zero point and press the zero button.
Acceptance of the value is acknowledged by flashing the LED 4…20mA 3 times, otherwise repeat
adjustment.
7.3 Adjustment Full-scale (60
– 100% of adjustment range)
Set the resistance potentiometer to the desired Full-scale and press the Full-scale button.
Acceptance of the value is acknowledged by flashing the LED 4…20mA 3 times, otherwise repeat
adjustment.
7.4 Current/ voltage output
To switch the current output to 4…20 mA, press and hold the Full-scale button for approx. 5s until the yellow
LED 4…20 mA lights up.
To switch the current output to 0…20 mA, press and hold the zero button for approx.. 5s until the yellow LED
4…20 mA goes out.
The voltage output is always s
et to 0…10 V independent of the current output.
7.5 Factory setting
The current output is factory set to 0…20 mA.
