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 performed after having completed the mechanical installation and the electrical connections.
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. Both first (close to the connector) and last beams are used as
synchronization beams.
A. Activate the Alignment mode by pushing the external NO contact (ACKNOWLEDGE/RESET/ALIGN push-
button, pin 3 of the M12-12 pole connector on the receiver) at power on until the second LED (red) begins to
flash indicating the activation of the Alignment mode.
B. Keep the receiver in a steady position and adjust the transmitter until the third LED (yellow) turns off. This
condition shows the alignment of the first synchronisation beam.
C. Rotate the transmitter, pivoting around the lower optics axis, until the fourth LED (yellow) turns off. This
condition shows the alignment of the last synchronisation beam.
D. Slightly turn both units both ways to find the limits of the area of maximum alignment level (). Place
both units in the centre of this area.
E. Fix the two units firmly using brackets.
Check that the alignment level on the receiver is maximum when the beams are not interrupted. Then check that all
level LEDs turn off when one single beam is interrupted. This check shall be made with the special cylindrical "Test
Piece" having a suitable size for the resolution of the device used (see the paragraph "Checks after first installation" of
the instruction manual).
F. Switch the device off and on to normal operating mode.
The alignment level is also monitored during normal operation mode and visualized on the same display (see
paragraph "Display" of the instruction manual.
Once the AOPD has been aligned and correctly fastened, the signal on the display is useful both to check the
alignment and to show a change in the environmental conditions (presence of dust, light disturbance and so on).
