Receiver Emitter
Signals are clearly identified through symbols allowing immediate reading, independent of bars directions.
A short description of the signalling LEDs is necessary to avoid misunderstandings.
Two yellow LEDs ( LAST, SYNC) on SG4-B receiver, facilitate the alignment procedure.
Correct alignment procedure
The light curtain alignment can be effected only after having completed the mechanical installation and the
electrical connections. The following procedure has to be followed:
NOTE: SG4-B is equipped with a system which informs the user on the alignment obtained.
The alignment function can be activated when powering the device, by keeping the normally open
RESET/RESTART contact closed for at least 0.5 seconds.
