LOW when the state
changes
No or incorrect supply voltage
1. Check supply voltage, compare with
type plate
2. Check terminal assignment
Output is set to HIGH
Incorrect monitoring resistor in sensor
1 or 2, or sensor short circuit
1. Check non-activated sensor;
resistance = 1k2 ±5%
2. Measured resistance deviates signifi-
cantly
Ä
Replace sensor
Cable break
1. Check activated sensor; resistance
< 400 ohms
2. Measured resistance deviates signifi-
cantly
Ä
Replace sensor
If supply voltage is correctly connected and
sensor is OK: control unit is faulty
