Alignment procedure
The alignment between the transmitter and the receiver is necessary to obtain the correct functioning of the AOPD. A
good alignment prevents outputs instability caused by dust or vibrations.
The alignment is perfect if the optical axes of the first and the last beams of the transmitter coincide with the optical
axes of the corresponding elements of the receiver. Two yellow LED indicators ( LAST, FIRST) facilitate the
alignment procedure. The operator can verify the operating condition of the AOPD through four LEDs on the receiver
and two LEDs on the transmitter.
The alignment is performed after having completed the mechanical installation and the electrical connections.

Disconnect the power supply.

Press the RESET button and keep it pressed (open the contact).

Re-connect the power supply.

Release the RESET button.

Check the LEDs at the bottom of the transmitter: if the green one (POWER ON) and the yellow one (EMISSION)
are ON, the unit is running correctly.
NB: The OSSD outputs are off in alignment mode.

Check which one of the following conditions is present on the receiver:
1. Red LED (
2. Green LED (
too.

Proceed with the following steps to change from condition 1 to condition 2:
A Keep the receiver in a steady position and adjust the transmitter until the lower yellow LED ( FIRST) turns
on. This condition shows the alignment of the first lower beam.
B Rotate the transmitter, pivoting around the lower optics axis, until the upper yellow LED ( LAST) turns on.
The red LED (
NB. Make sure that the green LED (
C Slightly turn both units both ways to find the limits of the area in which the green LED (
both units in the center of this area.

Fix the two units firmly using pins and brackets.

Disconnect the power supply.

Re-connect the power supply.

Check that the green LED on the receiver is on when the beams are not interrupted. Then check that the green
LED ( ) turns off and the red LED (
