In addition the LGB receiver displays the signal quality by LEDs:

All light beams are free and have good signal quality.

All light beams are free but partially with bad signal quality.
flashing (5 Hz)
One light beam is occupied but otherwise good signal quality.
Flashing (10 Hz) One light beam is occupied but otherwise bad signal quality.
on
Several light beams occupied.
In the case of improvement of the Light beam alignment between the TST LGB units the signal quality rises.
With good quality, the fault F 601 acknowledges itself automatically and the start up procedure may be con-
tinued.
6.2 Light beam adjustment
After successful alignment the light beam adjustment is performed during the calibration of the door end
positions automatically.
During the light beam adjustment, the TST LGB learns to recognize the reference positions of each light
beam. For this purpose, the door is closed slowly in automatic mode.
ATTENTION
The light beam adjustment must take place under the supervision of a trained mechanic.
During the adjustment, the monitored zone must be free.
If light curtain units are exchanged, a new light beam adjustment is requested.
