TROUBLESHOOTING

Solve possible problems according to the following table.
restored by this means, contact either the dealer from whom you bought the unit or TAKEX.
Trouble
The sensor does not
detect anything
The sensor sometimes
does not detect
anything
The sensor generates
an alarm, although
there are no people
within detection area
The operation LED is
on, but connected
devices are not
operating.
1. When cleaning, after wiping with a damp soft cloth, wipe off water droplets.
Periodic checks
If very dirty, lightly wipe with a diluted neutral detergent using a soft cloth, then wipe so that no
detergent remains.
Do not use solvents such as thinners or benzene. (Doing so may lead to deformation, discoloration, or
deterioration of plastic parts.)
2. Periodically (approximately weekly) confirm operation.
Check
(1) The power supply is not connected
(including broken wiring), or the power
supply voltage is low.
(2) The detection area is shielded by an object
(which may include glass).
(3) Unsuitable detection area settings
(including detection distance).
(4) Has not approximately 1 minute passed
since turning the power ON (has the
operation LED stopped blinking?)
(1) Unsuitable detection area settings
(including detection distance).
(2) The detection lens is covered with dust or
water droplets.
(3) Unsuitable detection or pulse count
settings.
(1) Unstable power supply voltage.
(2) Something is moving within the detection
area, or there are sudden changes in
temperature.
(3) A source of electrical noise (broadcasting
station, amateur radio station, etc.) is
nearby.
(4) Direct or refl ected light such as sunlight or
headlights sometimes shines onto the
sensor itself or into the detection area.
(5) The sensor is mounted on an angle (the
horizontal zone is tilted).
(6) Cars or motorcycles are sometimes detected
at the edge of the detection area.
(1) Wiring failure, broken wire, or short.
(2) Check that connected devices are operating
correctly.
If normal operations cannot be
Corrective Action
(1) Check the power wiring, and ensure
appropriate power supply voltage.
(2) Remove obstacles.
(3) Readjust detection area.
(4) Wait approximately 1 minute.
(1) Readjust detection area.
(2) After wiping with a damp soft cloth, wipe
off water droplets.
(3) Ensure appropriate detection and pulse
count settings.
(1) Ensure appropriate power supply voltage.
(2) Remove the problem object.
(3) Change the mounting location or remove
the noise source.
(4) Change the mounting location, or location
of the refl ective item.
Readjust detection area.
Use the area masking sheet to hide zones
for which detection is not required.
(5) Ensure the sensor is not mounted at an
angle.
(6) Reduce the set distance. Readjust detection
area.
(1) Connect wiring correctly.
(2) Investigate with reference to the
instruction manuals for the connected
devices.
