Service
An 8-pin M12 plug for service is located on the rear of the housing (for

Status of the optical connection. The OPT LED flashes when the optical connection
is stabilized through correct alignment.
SIGNAL
The optical signal strength is displayed as an alignment aid during adjustment of the
optical data couplers. Additional inform ation see chapter 6.1.
LASER ERROR
If the permissible internal temperature is exceeded, this LED flashes. The transm is-
sion power is not reduced. If an internal activation error such as overcurrent is de-
tected, the laser is switched off, and an attempt is then made every second to
resume normal operation. Meanwhile, the LASER ERROR LED lights for
30 s ... 60 s, even if the process was a one-off, e.g., as the result of an EMC event.
