the programm mode and go back to the normal operating
mode. All settings are saved to the internal memory on
leaving programming mode.
12.4 Service mode
The operation mode display H9 is flashing red.
The service mode is used for loading of the default settings.
All channel settings are saved to the internal non volatile
memory on leaving programming mode. Cutting off power
supply at just this time can result in storing incomplete data.
When the device is put to operation next time, service mode
is entered automatically.
In this case you have to press the button S2 (RESET)
1
to
load the factory default settings. These are for all channels:
- light mode operation
- basic transmit level low
- ALC delay disabled
- range low
- timer on-delay disabled
-
timer off-delay disabled
In some cases manual loading of the factory settings can be
desirable. For that purpose push the button S2 (RESET)
1
from the normal mode. During the lamp test, push the button
S2 again. The operating mode display H9 starts flashing
red (Service mode).
Press the button S2 (RESET)
1
once again. The amplifier
is loading the default settings and changes to the normal
mode automaticly.
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.

Do not wire the Master OUT terminal of the last
device with the Slave IN terminal of the first device.
