The standard installation described hereinafter is the one shown in Fig. 24,
i.e.
with the bar assembled
with the connectors pointing down.
5.1. Correct alignment procedure
The light curtain alignment can be effected only after having completed the mechanical installation and
the electrical connections as described above. Check alignment results with given table.
NOTE
: To enter alignment mode select the function as described in chapter 6.6.

align.
A
Keep the receiver in a steady position and set the emitter until the yellow LED (
SYNC) is
OFF. This condition shows the effective alignment of the first beam (synchronisation beam).
B
Rotate the emitter, pivoting on the lower optics axis, until the yellow LED (
LAST) is OFF.
NOTE:Ensure that the green LED (
NORMAL OP.) is steady ON.
C
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 (4) and then place
both units in the centre of this area.
D
Fix the two units firmly using brackets.
Verify that the green LED (
) on the RX unit is ON and beams are not interrupted, then
verify that the red LED SAFE (BREAK)
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 2.2.6 ”Controls after first installation”).
E
Switch OFF and ON the device in standard operating mode.
The alignment level is monitored also during device normal operation mode via display (see
chapter 7.2).
