The operator can check the status of the AOPD using four LEDs on the receiver and two LEDs on the transmitter.
The meaning of the LEDs on the receiver (RX) depends on the AOPD operating mode.
LEDs on the transmitter

Yellow LED (EMISSION): when on, the unit is transmitting correctly.

Green LED (POWER ON): when on, the unit is correctly powered.
LEDs on the receiver
Alignment mode
In this mode, the OSSD outputs are off (

Green LED (

Red LED ( ): on when the transmitter and the emitter are not aligned or an object is in the detection zone.

Yellow LED ( LAST): on when the last optical beam of the transmitter is correctly aligned with the
corresponding optical beam of the receiver (top of the device).

Yellow LED ( FIRST): on when the first optical beam of the transmitter is correctly aligned with the
corresponding optical beam of the receiver (bottom of the device).
Normal operation mode

Green LED (

Red LED ( ): on when an object is in the detection zone and the OSSD outputs are off.

Yellow LED (LAST): continuously on when the AOPD is in INTERLOCK mode. In order to reset the AOPD,
the TEST/RESET button must be pushed after the object has been removed from the detection zone. This
occurs only when the Manual Reset function is activated.
