Lateral actuation only from the shown sensor side
3.3 Switching distance
The side allows for a maximum height misalignment (X) of sensor
and actuator of ± 8 mm (e.g. mounting tolerance or due to guard door
sagging). The axial misalignment (Y) is max. ± 18 mm.

Preferred actuation directions: from front or from side
In case of a lateral actuation, the switching distances are
reduced by approx. 3 mm.
3.4 Adjustment
The continuous signal of the yellow LED signals the actuator detection; the
flashing of the yellow LED after a delay signals that the safety sensor is
actuated in the hysteresis area.
Recommended Adjustment
Align the safety sensor and actuator at a distance of 0.5 x s
ao
.
The correct functionality of both safety channels must be checked by
means of the connected safety-monitoring module.
