output and the red LED will stay OFF. If the light received doesn't exceed the maximum level,
perhaps due to a dirty lens, or doesn't fall below the minimum level, perhaps due to a background
reflection, then the red LED will flash and the weak signal output will turn ON. This condition will
continue until the normal light levels are received again by the sensor for one full cycle.

Pulse Frequency (S4)
(OFF=Pulse frequency 1, ON=Pulse frequency 2)
Setting two different pulse frequencies for two sensors prevents cross-talk between them
even for side-by-side mounting.
Selectable Switch Output (S5)
(OFF=Normally Open, On=Normally Closed)
Address preset to 00, can be changed via the master or
with a hand-held addressing device.
