Troubleshooting
The indications provided by the leds on the Emitter and Receiver make it possible to trace
the cause of any system malfunction. As indicated in the “LIGHT SIGNALS” paragraph of
this manual, in the case of a fault, the system switches to stop status and the leds of each
unit indicate the type of fault that has occurred. (See the tables below). The numbers of
the leds are referred to Figure 23.
