The Alignment mode is activated by pushing the RESET push-button for at least 0.5 s at power on.
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 “3” is
displayed (Maximum alignment). Place both units in the center 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
cylindrical “Test Piece” having a suitable size for the resolution of the device used (see paragraph “Checks after
first installation” of the instruction manual).
5 ) Switch the device off and on to normal operating mode.
