Self calibration
On self calibration the controller set up the correct gain for the connected light grid set,
determines the profile length and executes an error test. During self calibration the
monitoring area has to be uninterrupted (Exception: see automatic blanking).

Procedure:
Procedure:
1. Supply voltage must not be turned on.
The device has to be turned off.
2. No beam is interrupted.
3. Set DIP-switch 3 to position "on".
4. Power-on the device.
5. Take notice of the LEDs:
The green LED D should illuminate permanently.
No red Error-LED is flashing or light up permanently.
6. Set DIP-switch 3 back to position "off" while the system
stays powered up => D the controller stores the calculated values to the
EEPROM and turns back to normal operating mode.
If you don't want to store the new values, turn off the supply voltage while the
DIP-switch 3 is still in position "on".

Tip:
For use in elevators do the self calibration while the doors are open.
Otherwise the light curtain could switch during the elevator ride.

Could be accepted
Possible causes:
• Distance between receiver and transmitter is too
off
large
=> reduce distance or use transmitter with option
„increased power".
• Individual beams covered or polluted.
• Difference between the intensity of the brightest
and the darkest beam is too large.

Individual beams are detected as defective.
The system will only run in emergency operation!
