(1) Replace the cover to automatically start the operation check and walk test function (for 5 min) after 1 min of LED blinking.
(2) Check that the LED lights on both detection side (left and right) within the set detection area.
(3) Readjust the detection area if necessary.
(4) Anti-masking performs learning function for 3 min after cover is replaced. For this to be successful, do not have any object within
10cm of the lens during this period.
(5) Check also operation of connected devices, when applicable.
MAINTENANCE
1. Clean the device with a soft, damp cloth and wipe off water drops. Use water with weak neutral detergent to clean stubborn dirt.
Do not use substances such as thinner or benzene.
2. Perform operation check on a regular basis.
(1) No power supply (including broken wiring), or the
power supply voltage is low.
(2) The detection area is blocked by an object (which may
include glass).
(3) Unsuitable detection area settings (including
detection distance).
(4) Approximately 1 minute has not passed since turning
the power ON.
(1) Check the power wiring, and power supply voltage.

(1) Wiring failure, broken wire, or short-circuit.
(2) Check that connected devices are operating correctly.
(1) Connect wiring correctly.
(2) Investigate with reference to the instruction manuals
of the connected devices.
(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 reflected 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) Ensure appropriate power supply voltage.
(2) Identify the problem object, and remove it.
(3) Change the mounting location or remove the noise
source.
