Online operating mode:
The LED “Phase On” of the master
does not light (when the external trig-
ger is activated).
• Check whether you are working on a 25/
26-pin connector or the spring-loaded
terminals of a C-BOX 100.
• Is the sensor connected to the external
trigger input EXT TRIG?
• Is the light barrier supplied with electrical
power?
• Is one of the two EXT TRIG terminals
(NPN output) supplied?
• Is one of the two EXT TRIG terminals
connected to ground (PNP output)?
• Do the LEDs (if available) of the light bar-
riers work trouble-free?
• Is the sensor/reflector system (if availa-
ble) aligned correctly?
Online operating mode:
The LED “Phase On” of the master fol-
lows the trigger, but the read system
remains functionless (no read proc-
ess).

the application conditions (operating
mode, etc.)?
Check the corresponding parameters in
the operating modes folder of the config-
uration software.
Serial online operating mode:
The reader is not triggered (no read
process).
• Check whether "serial online" is activat-
ed as the “online options” in the operat-
ing modes folder of the configuration
software.
• Are the start and stop strings assigned
correctly?
• Is the serial trigger source connected
correctly?
Online operating mode and serial

The reader does not respond correctly
to the signal end.

for read cycle” in the operating modes
folder of the configuration software.
