Problem

Possible cause

Troubleshooting

No LED display

No voltage supply

Apply voltage 

Power LED flashes 

and sensor does not 

switch

• Undervoltage

• Overvoltage

Correct the voltage  

(→ 11 Technical data)

Power LED off and 

signal LED flashes

Internal or external fault

• Undamp / damp

• Power off / on

• Replace the unit

• Check wiring / connections

• Check external electronics (e�g� 

G150xS or PLC)

13  Maintenance, repair and disposal

If used correctly no maintenance and repair measures are necessary� 

Only the manufacturer is allowed to repair the unit� 

After use dispose of the unit in an environmentally friendly way in accordance with 

the applicable national regulations�
