Adjusting the Response Time:
The sensor’s response time can be adjusted by turning the response time adjustment knob.
Response time can be adjusted according to how quickly an object breaks the sensor beam.
NOTE: A faster response time increases the chance of a false alarm. A slower response time
increases the chance of missing a broken beam.

Adjusting the Alignment:
The sensor can be adjusted ± 5° vertically and ± 90° horizontally once the unit is mounted and
power is connected.
1.
Remove the sensor cover and look into one of the alignment viewfinders (located between
the two lenses) at a 45° angle.
2.
Adjust the horizontal and vertical angles of the lens until the reflector is clearly seen in the
viewfinder.
3.
Replace the sensor cover.

Fine-Tuning the Sensor:
Once the sensor is mounted and aligned, the sensor can be
fine-tuned using the voltage output jack.
1.
Set the range of a volt-ohm meter (VOM) to 1~10 VDC.
2.
Insert the red (+) probe into the (+) terminal and the black
(–) probe into the (–) terminal.
3.
Measure the voltage (see table).
4.
Adjust the horizontal and vertical angles until the VOM
indicates the highest voltage.
NOTE: Do not interrupt the beam while adjusting alignment.
