TROUBLESHOOTING

The indications provided by the LEDs present on the Emitter and Receiver units make it
possible to trace the cause of a system malfunction.
As indicated in the "SIGNALS" chapter of this manual, in the case of a fault, the system is
blocked and the type of fault can be identified by the LEDs present on the Emitter and
Receiver units. (See the tables below).

Carefully locate the interfering
Emitter and take action in one
of the following ways:
Switch the position of the
Emitter and Receiver.
Move the interfering Emitter
to avoid this illuminating the
Receiver.
Shield the beams coming
from the interfering Emitter
using opaque protections.
