Troubleshooting

Symptom
Sensor detection is not correctly conveyed
to a system device.
The operation indicator blinks in red and
blue alternately during calibration
(calibration error).
A vehicle entering the detection area is
occasionally not detected or never detected.
The sensor does not revert back to
non-detection status when a vehicle leaves
the detection area, or takes long to change
status.
A vehicle was detected, but it changed to
non-detection.
The sensor detects a vehicle outside of
the detection area.
The sensor detects a pedestrian passing
through the sensor's detection area.
The sensor detects a pedestrian with large
baggage or a metal object passing through
the sensor's detection area.
Sensor detection is too slow.
Detection is required from a farther location.
A vehicle returning immediately after
leaving is not detected.
Cause
The supply voltage may not be correct.
The power supply polarity is wrong (a wrong polarity
does not cause a failure but the product will not work).
The relay output wiring may not be correct.
Output contact type is incorrect.
A pedestrian or an object in the detection
area is detected.
The direction of the sensor (detection area)
is not correct.
The supply voltage may not be correct.
Calibration is not properly performed.
The direction of the sensor (detection area)
is not correct.
The sensor may be affected by the background.
The detection range may be too short.
Detection sensitivity is too slow.
Human cancellation is high.
There is a pedestrian, bicycle, large package,
tall weeds, etc. in the detection area.
There is an object attached to the sensor
surface such as chewing gum.
Calibration is not properly performed.
The direction of the sensor (detection area)
is not correct.
Installation location and settings of
the sensor are incorrect.
A vehicle is parked partially in the detection area.
Off-delay timer is too long.
The detection range may be too short.
The direction of the sensor (detection area)
is not correct.
Installation location and settings of
the sensor are incorrect.
A vehicle is parked partially in the detection area.
Off-delay timer is too short.
Detection sensitivity is too high.
The detection range is too long.
The direction of the sensor (detection area)
is not correct.
Detection sensitivity is too high.
Human cancellation is low.
More than one pedestrian is passing.
Detection sensitivity is too high.
Human cancellation is low.
The metal object or baggage is too large.
Detection sensitivity is too slow.
Human cancellation is high.
The detection range may be too short.
"Application" selection is incorrect.
Sensitivity is too low.
Sensitivity boost is disabled.
Sensitivity boost timer is set too short.

Action
Connect to a 12–24VAC/DC power supply.
Connect to a 12–24VAC/DC power supply.
Wire positive/negative contacts of
the sensor power source correctly.
Wire the relay output correctly.
Select the correct output contact type for the system device.
Remove the pedestrian or object (e.g. flag,
banner, weeds) in front of the sensor. If it
cannot be removed, reduce the detection range.
Adjust the sensor's direction so that it is not affected
by nearby vehicles, walls (fences), or gate bars.
Connect to a 12–24VAC/DC power supply.
Connect to a 12–24VAC/DC power supply.
Adjust the sensor's direction (detection area)
to face the correct direction.
Increase the detection range.
Increase the detection sensitivity.
Lower the human cancellation.
Reduce the non-detection sensitivity.
Remove these objects from the detection area. If they
cannot be removed, reduce the detection range.
Remove the object.
Adjust the sensor's direction (detection area)
to face the correct direction.
Select the "Application" and "Angle" according to
the installation location, and adjust the parameters.
Guide the vehicle so that it is parked within
the detection area.

prevent people from entering the area.
Reduce the detection sensitivity.
Increase the human cancellation.
The sensor may not discriminate between
large objects and vehicles. Take measures to
prevent people from entering the area.
Increase the detection sensitivity.
