SL-V-M-NO6-E
6-3 Center Indicator
Center indicators are present on both the transmitters and receivers.
Center indicator (Upper) : indicates whether interruption is present in the top beam axis or not.
(clear or blocked)
Center indicator (Middle) :
indicates whether the middle axis beams are interrupted or not. The
SL-V08H(S) and SL-V04L do not have this indicator.
Center indicator (Lower) : indicates whether interruption is present in the bottom beam axis or
not. (clear or blocked)
In case of series connection, the indicators on each unit independently indicate according to their own situation.
See "Series Connection" (page 2-6)
Applying the fixed blanking function to a beam reverses the clear and blocked results for that beam.
See "Fixed Blanking" (page 2-48)
