7.6.7 Calibrating the safety light curtain
To adjust the range and sensitivity of the Safety Light Curtain:
1. Ensure the area between the Safety Light Curtain transmitter and receiver is free from
obstructions.
2. Ensure the light beam paths are not broken and the Personnel Sensor is disabled so that the
sash does not Auto-Close whilst the Safety Light Curtain is being calibrated.
Note: If it is not possible to disable the Personnel Sensor, remove the motor / clutch
connector from the Auto Sash Control Unit. This activates the Sash Control Alarm
after the selected time delay and the reset button must be pressed once the Safety
Light Curtain has been calibrated.
3. Remove the cover from the Safety Light Curtain Control Box.
