7.1 LIGHT CURTAIN ALIGNMENT PROCEDURE
The light curtain alignment can be performed only after having completed the mechanical installation and the
electrical connections as described above. Compare alignment results with those given in the following table.
To enter alignment mode, see paragraph 6.9
– “”.
In alignment mode the OSSDs of the light curtain are in OFF state

1. Keep the active unit in a steady position and set the passive unit until the yellow LED ( FIRST) is
OFF. This condition shows the alignment of the first emitter/receiver couple.
2. Rotate the passive unit, pivoting on the lower optics axis, until the yellow LED ( LAST) is OFF.
Note: Ensure that the green LED ( NORMAL OPERATION) is steady ON.
3. Delimit the area in which the green LED ( ) is steady through some micro adjustments - for the
first and then for the second unit - so to have the maximum alignment (3) and then place both units
in the centre of this area.
4. Fix the two units firmly using brackets. Verify that the green LED ( ) on the active unit is ON and
beams are not interrupted, then verify that the red LED SAFE ( ) turns ON if even one single
beam is interrupted (condition where an object has been detected). This verification shall be made
with the special cylindrical “Test Piece” having a size suitable to the resolution of the device used
(refer paragraph 3.2.6
– “Controls after first installation”).
5. Switch OFF and ON the device in normal operating mode.
