Operating Instructions
8-channel light barrier multiplexer
IMX-A840
GB
12.5 Error after self test
The operation mode display H9 is flashing red.
After turning on, the device starts a self test. If there is an
internal error, the multiplexer displays this with the flashing
red LED H9 and goes inoperative. Now you have to consult
the manufacturer.
13. Master-Slave operation
The master-slave operation allows synchronized action of
multiple 8-channel devices, including manual and automatic
series. Therefore, the same channel number is active on
each device in the chain at the certain time (see
picture 8
).
With a suitable arrangement of sensor pairs, the influence
between the multiplexer can be prevented.
i
Do not wire the Master OUT terminal of the last
device with the Slave IN terminal of the first device.
