Fix the two units firmly using brackets.
Verify that the green LED (
) on the RX unit is ON and beams are not interrupted, then verify that the red LED
(
) turns ON if even one single beam is interrupted (condition where an object has been detected).
This verification shall be made with the special cylindrical “Test Piece” having a size suitable to the resolution of the
device used.
NOTE: Passing the Test Piece along the whole sensitive area and at any distance from the two units, the red LED
(
) shall be always ON and never change status.
A daily test is recommended.
DIAGNOSTIC FUNCTIONS
The operator can visualise the operating condition of the light curtains through the four LEDs positioned on the receiver
unit and two LEDs on the emitter unit.
The figure below shows all signalling LEDs modes: OFF, ON and BLINKING.
The operator is able to check the main causes of the system stop and failure, using the same LEDs used for visualising
the functions. For Receiver:

LED
OSSD error (yellow and red BLINKING)
Check OSSD connections; make sure that they are not in contact with one
another or with the supply cables, then Reset. If the failure continues
contact DATALOGIC AUTOMATION
Internal error (red ON
yellow BLINKING)
Switch OFF and switch ON the supply circuit; if the failure continues contact
DATALOGIC AUTOMATION
Optical error (red ON yellow BLINKING)
Reset. If the failure continues contact DATALOGIC AUTOMATION
Error status
No power supply
(LEDs OFF)
Check connections and input voltage correct value.
If the failure continues contact DATALOGIC AUTOMATION
