ALIGNMENT OF EMITTER AND RECEIVER (Fig. 4)
The last operation you have to perform is the emitter / receiver alignment.
Ensure that the stands of emitter and receiver are in a vertical position (placing a spirit level (
A
) on
the top end of each stand). Perform leveling fine adjustments by means of the hexagonal nuts of the
stand bottom (
B
).
Connect the light curtain / the light grid. (ref. Curtain technical manual).
For an exact alignment of emitter and receiver, loosen the three allen screws (
C
) that fix the rotation
flange and rotate the two columns until the barrier signal LEDS light on (ref. Technical manual).
