Troubleshooting and remedies
Fault indication Possible cause Remedy
Green “Power” LED does
not light up
No or incorrect supply voltage 1. Check supply voltage, compare with
type plate
2. Check terminal assignment
If supply voltage is correctly connected:
control unit is faulty
Ä
Replace control unit
Green “Sensor” LED
does not light up
and
signal output M1 is set
to LOW
Incorrect monitoring resistor on the
sensor
Ä
Connect sensor to monitoring resis-
tor 1k2 or 8k2
Sensor incorrectly connected
Ä
Check terminal assignment
Ä
Sensor with 1k2 connected to Y1
and Y2?
Ä
Sensor with 8k2 connected to Y1
and Y3?
If monitoring resistor is correct: sensor is
faulty
Ä
Replace sensor
