6. Diagnostic
Transmitters and receivers are equipped with an integrated signal lamp
in the transparent end cap The signal lamp indicates the operating
status or, in the event of a fault, a fault code
If there are no faults during operation, the status indicator
on the transmitter goes out after 10 minutes
6.1 Indication of configuration when system starts
The transmitters and receivers indicate the set beam coding once after
5 seconds when the system starts A number of short light impulses are
output in the process, which correlates with the number of the beam
coding
On the receiver, the indicator is delayed until there is no
change in the ON state or OFF state of the OSSDs for
5 seconds
