Error search
Wrong output signal (current/voltage) OUT (terminal 1
– 2 – 3)
Cause
The device is not configured correctly
Remedy
Check commissioning
For selected output range 4-20 mA (2-10V) the current is < 3,8 mA ( the voltage is <1,9V)
Cause
Sensor short-circuit or sensor interruption
Remedy
Check sensor/wire at terminal 5-6-7
