Light control

Installation steps (critical doors and floors / without door function):

For increased functional security when installing in front of the door, the reception signals 
(reference values) must be programmed into the light curtain when the door is open and the 
area to be protected is clear.

• 

The LIGI is installed as explained in the operating instructions, i.e. the transmitter is 
connected as indicated in the table above (bottom row).

•  When the door is open and the area to be protected is clear, the sync connection 

between the transmitter and receiver is connected/hot-wired with 10-30 V DC 
using a short filament for a very short period of time (less than 1s). Everything 
else will now happen automatically.

• 

If the previous step has been carried out correctly, the green LED on the receiver will 
be continuously on and the red LED will flash. The reference values will then be pro-
grammed. It is essential to keep the area to be protected clear during this time. This 
programming process will take 10s and the red LED will then go out.
