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.
The beam used to synchronise the two units is the one closest to the connector. FIRST is the optics connected with
this beam and LAST is the optics connected to the last beam when starting from FIRST.
The alignment is performed after having completed the mechanical installation and the electrical connections.
1. Activate the Alignment mode by pushing the external NO contact (ACKNOWLEDGE/RESET push-button) for
at least 0.5 s at power-on.
2. Keep the receiver in a steady position and adjust the transmitter until the yellow LED (
condition shows the alignment of the first synchronisation beam.
3. Rotate the transmitter, pivoting around the lower optics axis, until the yellow LED (
NB: Make sure that the green LED (
4. Slightly turn both units both ways to find the limits of the area in which the green LED (
is displayed (Maximum alignment). Place both units in the centre of this area.
5. Fix the two units firmly using brackets.
6. Check that the green LED (

7. Switch the device off and on to normal operating mode.
NB: The OSSD outputs are off in alignment mode.
