Operation diagram and truth table valid for an amplifier
during its multiplex activated mode (trigger signal ON).
During standby mode (trigger signal OFF) the amplifier
status is like "no-object-present", e.g. light received.

Under normal operating conditions, the yellow level indi-
cationLED has to be on steadily (bright).

A multiplexed system consists
of 1 master amplifier which
initialises the multiplex cycle
with a trigger signal, and up to
10 slave amplifiers connected
together in a loop via the trig-
ger signal. Pin 9 (trigger signal
output of the last slave ampli-
fier is connected to the trigger
input of the master. Each
photoelectric switch has its
own amplifier with a relay out-
put. A multiplexed system
allows the use of up to 11
long range photoelectric
switches
mounted near one
another, without having false
output signals due to optical
crosstalk.
