8.  DIAGNOSTIC FUNCTIONS AND LED INTERFACE ERROR SIGNALLING 

8.1.  Device status visualisation 

The operator can verify the device functioning status using the three LEDs present the receiver unit and 
the one present on the emitter unit. 
 
The meaning of the LEDs present of the receiver unit (RX) depends on the light grid operating mode. 
 

RECEIVING UNIT (RX)

Status 

 

-  No power supply. 
-  Microprocessor in the reset condition. 
 

 

-  Normal RX functioning 
 

 

-  Presence of object inside sensitive area or units misaligned. 
 

 

-  Short-circuit signalling on switching output 
 

 

-  Generic anomaly on RX unit 
 

 

-  Critical alignment of the TX and RX units or weak received signal.
