Troubleshooting:
Sensor does not detect the object.
•
Check the sensor’s alignment.
• Readjust the sensor’s response time.
Alarm LED will not turn ON when the beam
is interrupted
•
Clean the sensor and reflector with a damp
(not wet) cloth.
• Adjust the reflector and/or sensor for proper
alignment.
Alarm LED turns ON
when object is
detected, but there is no output
•
Check wiring between the sensor and local
alarm device.
Alarm LED is continuously ON
•
Check the sensor’s alignment.
• Check for any objects between the sensor
and reflector that may be causing false
alarms.
Alarm output becomes erratic in bad
weather
•
Check the sensor’s alignment.
• Readjust the sensor’s response time.
Frequent false alarms from leaves, birds,
or other objects
•
Readjust the sensor’s response time.
• Change the sensor’s location.

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.
