Alignment procedure
The alignment between the active and the passive unit is necessary to obtain the correct functioning of the AOPD. A
good alignment prevents outputs instability due to dust or vibration.
The alignment is perfect if the optical axes of the beams of the active unit coincide with the optical axes of the
corresponding mirrors on the passive unit.
The alignment is performed after having completed the mechanical installation and the electrical connections.
The Alignment mode is activated by pushing the external NC contact (RESET/ACKNOWLDGE/RESET MODE push-
button) for at least 0.5 s at power on.
A display helps the user control and check the status of the AOPD, in Alignment mode, in normal operation mode and
when troubleshooting. The display consists in four LEDs and a 7-segment display on the active unit.
