Optical Setting of the Sensor

You can swivel the sensing field away from the door or towards the door by setting the detection an-
gle. The detection angle can be adjusted from 0° to + 25°.
Use the handle on the chassis (d) to set the detection angle.
To adjust the detection angle, use the M3 screw (g) at the top of the module holder.

Use the sensing range screw (f) to adjust the sensing range.
By turning the sensing range screw (f) with a screwdriver, the receiver lens is shifted and the sensing
range is set.
A bi-color status LED (p) assists in setting the exact sensing range over the ground.
If the sensor is not used for protection in complying with German standard DIN 18650, a higher
adjustment (no more than 80 cm) is possible.

If used as a means of protection in complying with German standard DIN 18650,
the detection angle and the sensing range have to be adjusted as follows:

Use the optional calibration tools (test card and square) for adjustment.
Sensing range adjustment of the Sensor:
1. Use the chassis lever to move the module to the first marked line on the module holder (see
Figure 5.2), and use the M3 screw to fasten (g).
2. Turn the sensing range adjustment screw (f) counterclockwise until its overturn protection is
activated (slight "clicking" noise). Now the maximum sensing range has been set.
3. Now place the test card on the test specimen so that the card lays 12.5 cm above the ground.
4. Turn the sensing range adjustment screw clockwise just until the LED display switches from red
to green (if necessary turn back to red and then clockwise to just to green).
The sensing range adjustment is thus completed.
