Switching input/output
The device is equipped with a switching output IO1 and a switching input IO2.
• Using the switching input, the transmitter (pin 4) can be activated and deactivated. On deactivation, the
optical link is interrupted (OLK LED).
NOTICE
Deactivation of the transmitter can be used during a corridor change to avoid interference ef-
fects, e.g., with other optical sensors.
• If the received signal level drops (SIGNAL QUALITY), the intensity warning is activated via the switch-
ing output.
The intensity warning is activated as soon as no green LED illuminates on the SIGNAL QUALITY indi-
cator.
NOTICE
Data transmission remains active until the last orange LED of the SIGNAL QUALITY indicator
switches off. Data transmission is then deactivated.
The intensity warning remains active even after the last orange LED of the SIGNAL QUALITY
indicator switches off.

Connection cable shield
The shield of the connection cable is on the thread of the M12 con-
nector plug.
The thread of the M12 connector plug is part of the metallic hous-
ing. The housing is at the potential of the functional earth via pin 5.
