4. Activate the initialization procedure by pressing the button (3). The detection
distance must not be interrupted during initialization!
 During initialization, the following is displayed on the adjustment device:

Troubleshooting during initialization
 If the standardized signal value is not within 100 % ±3 % or if the detection
indication displayed deviates by more than 10 % from the effective detection
distance, repeat the initialization process from step 4.
 If initialization fails, the following is displayed:
Initialization
failed
Remedy the error and repeat the initialization process. Possible causes for
failed initialization:
Signal Possible cause
Not stable Moving obstacle
Too high Strong reflection
Too low  Detection distance too large
 Reflector too small
 Reflector aligned incorrectly
 Reflector covered
