DANGER!
Risk of personal injury or property damage due to electric current!
Voltage conducting parts may cause personal injury or damage to equipment.
• The electric device may only be connected by appropriately qualified personnel.
5.3 Diagnostics
Causes for Triggering the Contamination Warning (blinking LED):
Display LED
Diagnosis/Cause
Elimination
Continuous blinking
at approx. 2.5 Hz
Contamination
Carefully clean the optic cover and the reflector with a
cloth.
Aged emitter diode
Replace the sensor.
Unreliable working range
Check distance to the sensor (see
).
Continuous blinking
at approx. 5 Hz
Short-circuit
Check electrical wiring and eliminate the short-circuit.
Hardware error
Replace the sensor.
