3.3 Adjustment
The LED in the end cap of the safety sensor can be used as adjustment
tool.
The yellow flashing LED of a sensor signals if an adjustment of the
switching distance is required. Reduce the distance between the sensor
and the actuator, until the LED in the end cap of the safety sensor is
continuously lit yellow. In this position, a reliable switching position
of the sensor is obtained. (also refer to "Operating Principle of the
Diagnostic Outputs").
The proper functionality must always be checked by means of the
connected safety-monitoring module.
3.4 Switch distance
The graphs show the switch-on and switch-off points of the sensor
due to the approach of the actuator. The maximum misalignment of
the actuator with regard to the sensor centre is 7 mm. A concealed
mounting of the sensor and the actuator will reduce the switching
distance.
