1 ) Keep the active unit in a steady position and adjust the passive unit until the yellow LED ( FIRST) turns off.
This condition shows the alignment of the first transmitter/receiver couple.
2 ) Rotate the passive unit, pivoting around the lower optics axis, until the yellow LED ( LAST) turns off.
NB: Make sure that the green LED ( ) is on and steady.
3 ) Slightly turn both units both ways to find the limits of the area in which the green LED ( ) is steady and
“4” is
displayed (Maximum alignment). Place both units in the centre of this area.
4 ) Fix the two units firmly using brackets.
Check that the green LED ( ) on the active unit is on when the beams are not interrupted. Then check that
the red LED ( ) turns on when one single beam is interrupted. This check shall be made with the special
cyli
ndrical “Test Piece” having a suitable size for the resolution of the device used (see paragraph
3.3
– “Checks after first installation”).
5 ) Switch the device off and on to normal operating mode.
The alignment level is also monitored during normal operating mode and visualized on the display.
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). The
behaviour is summarized in the next table.
