Diagnostic
If a fault occurs on either the
emitter or receiver the Alarm
LED will turn ON.
Receiver fault
During normal operation the
receiver is monitored for
faults.
If the wires are short-circuited
the "Code A, Green LED"
flashes at a rate of 2 Hz.
If the wires are broken the
"Code A, Green LED" flashes
at a rate of 4 Hz.
Emitter fault
During normal operation the
emitter is monitored for
faults.
If the wires are short-circuited
the "Code B, Yellow LED"
flashes at a rate of 2 Hz.
If the wires are broken the
"Code B, Yellow LED" flashes
at a rate of 4 Hz.
Alignment
If the alignment DIP switch
is set the Yellow Signal LED
Flashes according to the
signal quality.
Low frequency means weak
signal.
Steady indication means
maximum signal. On long
distance it is not possible to
get a steady signal but the
alignment is optimal when
the led flashes with the high-
est frequency.
On short distance the emit-
ter power can be reduced
using the potentiometer and
then get better readings in
the alignment LED.
NB! In alignment mode the
output is off.
Code A or B
When two master/slave net-
works are mounted close to
each other it is recommend-
ed to select one set to Code
A and the other to Code B
to avoid crosstalk.
Trigger fault
If the triggerwire is interrupted
the Alarm LED will turn on.
Master / Slave
Select the first amplifier in the
loop to be master and the rest
to be slave. See wiring dia-
gram

initialized automatically by the
master each 350 ms or,
immediately after the last
slave amplifier in the loop has
been activated, if the trigger
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.
