Troubleshooting Measures
Door will not open even if a
person comes close to it.
Off
Green
For no reason, the door
opens and closes
(ghosting)
A rain cover (sold separately) protects the sensor from snow and rain when installed outside.
Blue
Insert the sensor
connector correctly until it
clicks.
Supply the correct voltage
to the sensor.
(12~24V AC/DC)
Remove the moving object
from the detection area.
Reduce the radar sensitivity
volume to an appropriate value
according to the manual.
Activate the snow mode
setting
Set the presence timer
setting to 30 or 60 seconds.
Remove the highly reflective object
from the detection area or lower the
IR sensitivity volume.
Voltage failure
Defective wiring
There is a moving object
in the detection area
The radar sensitivity volume has
been set too high relative to the
installation environment.
Dust, frost, water droplets
are on the lens
Defective wiring
Excessive reflections in the infrared
detection area
Red
There is a moving object in the radar
detection area.
Remove the moving objects.

13. Spot finder
(not provided)
A spot finder can be used to accurately locate the position of the infrared detection area and is a useful tool during the commissioning of this sensor.
MODEL : WC-IR/BL
Green + Red
Infrared reflectivity is too low
Adjust the mounting height or IR
sensitivity. If necessary, deactivate
low reflection setting(Menu:141)
An automatic doors
keeps open.
Set the frequency setting of both
sensors to be different (Menu: 041)
Detection area overlaps
with that of another sensor
Sensitivity value is too low
Increase the radar sensitivity volume
to an appropriate value.
Loose connector
Recheck wiring

After completing installation, walk into the detection area of the sensor. If you feel that the detection
area is incorrect, then adjust it as per section 8. The infrared spot finder SF100 is recommended to
accurately set the infrared detection area.The IR sensitivity volume can also be increased/
decreased if detection problems persist.
If the device detects when there is nothing in the infrared detection area,
turn the sensitivity volume counter-clockwise.
