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 turns
ON if even one single beam is interrupted SAFE
, 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 to paragraph 3.2.6 “
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 paragraph 7.1 on the
Instruction Manual).
Once the curtain has been aligned and correctly fastened, the display signal is useful both to check the alignment and
show a change in the environmental conditions (occurrence of dust, light disturbance and so on) via signal level
monitoring.
