Adjusting the Pattern Depth
Setting the Sensitivity
Normally set to “M.” 
“H” increases the sensitivity and “L” lowers the sensitivity.
Setting the Presence timer
1st Row from door provide 
the presence detection. 
(1) Select the presence timer. 
(2) Turn the power off and on again. Otherwise it may leave
door open for the duration of the presence time set.
(3) After making sure that the door closes, wait for 10
seconds before entering the detection area to set the 
Presence timer.
Setting the Frequency Function 
(Interference Prevention)
Four different frequencies 
can be set by adjusting 
the Dipswitch 3 and 4.
 Note 
When two or more sensors are installed close to each other, 
it is possible that they interfere. When that happens, 
 change the Frequency.
Setting the immunity mode
Set the Dipswitch5 if the 
sensor is used in a region 
with snow or a lot of insects.

 between -4
 to 4 (1 per click)
 by Adjustment Screw.

TROUBLESHOOTING
Inform the following items to the building owner/operator
1. When turning the power on, always walk-test the sensor pattern to ensure proper operation.
2. Always keep the detection window clean. If dirty, wipe the window with a damp cloth. (Do not use any cleaner or solvent.)
3. Do not wash the sensor with water.
4. Do not disassemble, rebuild or repair the sensor yourself; otherwise electric shock may occur.
5. Contact your installer or the sales engineer if you want to change the settings.
6. Do not place an object that moves or emits light in the detection area. (Ex. Plant, illumination, etc.)
7. Do not paint the Detection Window.
Contact your installer or the sales engineer if:
 - you need to change the settings or replace the sensor.
 - the trouble still persists after checking and remedying as described above.

condition change in the detection area.
Adjust to stated voltage. 
Check the wiring and the connector.
Wipe the detection window with a damp cloth. (Do not 
use any cleaner or solvent.) 
Set the Sensitivity Switch “H.”
Set the Sensitivity Switch “L.”
Remove the object.
Remove the object.
Secure the header. Or set the Sensitivity Switch “L.”
Install in a place keeping the waterdrops off. OR
use a rain-cover (Optional).
Set the different frequency position each other.
Adjust the detection area to deep (outside).
Turn the power off and on again.
Trouble Possible Cause Solution
There was a puddle left by rain or snow. 
The floor has gotten wet.
The exhaust of the car and the fog penetrate into the 
detection area.
This sensor is equipped with the anti-malfunction. 
However, pay attention when installing as malfunction
