Test Plug Construction
Emitter Female Plug Connector
Using Female Plug Connector FF-
SBZ1721137, connect pins A4 and A5 to
supply voltage and the ground pin to earth
ground.
Emitter Board Visual Test
1. Clean the front lens window of the emitter.
2. Place your eye against the emitter front lens window and observe the presence of a low
energy red light (a spot) in the middle of each beam (except synchronization).
3. If you can observe the presence of this red light, the emitter is working correctly. If you
cannot, replace the faulty emitter board.
