7 ALIGNMENT PROCEDURE
The good alignment between the active and the passive unit of the ESPE is necessary to obtain the correct
behavior of the light curtain. A good alignment avoids a not steady light curtain status (OSSDs flicker on

off
and vice versa) due to dust or vibration.
The alignment is perfect if the optic axes of the active
unit’s beams coincide with the optic axes of the
corresponding mirrors on the passive unit.
It is important to define the means of symbol drawn on optic side of light curtain.
The direction of arrows associated to the two yellow LEDs are correlated to the first and the last
emitter/receiver couple, referring the position of M12 connector. Signals are clearly identified through
symbols allowing their immediate reading, independent of bars directions; a short description of LEDs
signals proves nevertheless necessary so as to avoid misunderstandings.

Figure 53
Figure 54 shows that the first couple emitter/receiver is the nearest to M12 connector; the last couple
emitter/receiver is the farther to M12 connector.
The standard installation described hereinafter is the one shown in Figure 54 for a SG4-RB4 model, i.e. with
the bar assembled with the connectors pointing down. In SG4-RB2 models, obviously, the first and the last
couple coincide.

One-digit display can inform the user about the level of alignment of the array of beams.
In alignment mode the internal and external lamps blink as quickly as the alignment level increases.
