ALIGNMENT AND OPERATION
BEAM ALIGNMENT
①With the cover detached, face the sensor lenses towards
the reflector.
Adjust the angle of the sensor unit vertically and
horizontally by looking through the view finder placed
between the sensor lenses.
Adjust it until the center of the reflector can be seen in the
middle of the view finder.
②Supply power to the sensor.
When the sensor and reflector are properly installed at the
same height, alarm LED will remain OFF.
③After confirming that the alarm LED is OFF, place the
attenuation sheet on the optics of the sensor and check if
the attenuation LED is OFF.
Please note that there are two types of attenuation sheets.
(indoor use and outdoor use)
④If the attenuation LED lights, make adjustment again
until it turns OFF.
⑤Fine tuning should be done by monitoring the output
voltage using a volt meter.
(See the table below.) until obtaining the peak voltage.
Monitor output voltage
2.6V or more
1.4 to 2.6V
less than 1.4V
・The above voltage shows the monitor output when
Note :
the lenses are covered by the attenuation sheet.
・Using the attenuation sheet and a voltmeter ensures
optimum performance of the sensor.
⑥Remove the attenuation sheet after aligning the reflector
beam (and retain for future use) before fitting the front
cover.
OPERATION CHECK
・After installing the sensor and making the alignment
adjustment, check the operation of the sensor, with its
cover attached, by looking at the alarm LED on the sensor.
①Make sure that the alarm LED is OFF.
②When the infrared beam is interrupted, the alarm LED
lights.
It indicates that the operation is normal.
The relay operates during the interruption time for a
minimum of 2 seconds.
③Walk through the infrared beam between the sensor and
the reflector and make sure that the alarm LED lights up
and then goes off.

RESPONSE TIME
Adjust response time as follows. The unit does not detect a passing object faster than the response time setting. If the
response time is set longer, the unit does not detect human beings. Adjust to a little longer response time in a site where large
objects such as birds, newspaper, or falling leaves may pass through the beam path.
