Troubleshooting

Symptom
Operation indicator does not turn On.
Sensor detection is not correctly conveyed
to a system device.
The operation indicator blinks in red and
yellow alternately during calibration
(unstable error).
The operation indicator blinks in red and
blue alternately during calibration (high
reflection 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 pedestrian entering
the detection area.
Cause
Power may not be supplied.
The supply voltage may not be correct.
The relay output wiring is incorrect.
Output contact type is incorrect.
There is some movement while the
calibration in progress.
A person or an object in the detection area
is detected.
The height of the unit is too low and the
ground is being detected.
The ground is detected because the pole
on which the sensor is installed or the
ground is tilted.
The angle of the sensor (detection area)
is not correct.
There is slide gate or swing gate in the
detection area.
Power may not be supplied.
The supply voltage may not be correct.
Calibration is not properly performed.
The angle of the sensor (detection area) is
not correct.
The sensor may be affected by the
background.
The detection range may be too short.
Main or Close range sensitivity is too low.
Relay response time is too long.
Fine tuning presence is too 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 angle of the sensor (detection area) is
not correct.
Installation location and settings of
the sensor are incorrect.
Hold timer is too long.
Fine tuning presence may be too low.
The detection range may be too short.
The angle of the sensor (detection area) is
not correct.
Installation location and settings of
the sensor are incorrect.
Hold timer is too short.
Main or Close range sensitivity is too high.
Relay response time is too short.
More than one pedestrian passing.

Action
Connect to a 12 to 24VAC/DC power supply.
Connect to a 12 to 24VAC/DC power supply.
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) from the detection area and
perform calibration again.
The ground in the detection area is uneven,
such as grating. Step back people or
remove objects in the detection area. If the
object cannot be removed, shorten the
detection range.
Install the sensor so that the bottom of the
main unit is 500mm(5in.) above the ground.
If the pole is tilted against the ground, the
sensor may not operate properly. Please
install the sensor on a pole standing up
straight.
Adjust the sensor's angle so that it is not
affected by nearby vehicles, walls (fences),
or barrier arms.
Adjust the sensor's angle (detection area)
15 degree away from the gate.
Connect to a 12 to 24VAC/DC power supply.
Connect to a 12 to 24VAC/DC power supply.
Perform calibration correctly.
Adjust the sensor's angle (detection area)
to face the correct angle.
Perform calibration again.
Increase the detection range.
Increase Main or Close range sensitivity.
Shorter Relay response time.
Reduce Fine tuning presence.
Remove these objects from the detection
area. If they cannot be removed, reduce the
detection range.
Remove the object.
Perform calibration properly.
Adjust the sensor's angle (detection area)
to face the correct angle.
Select the "Application" according to the
installation location, and adjust the
Set Hold timer shorter.
Increase Fine tuning presence.
Increase the detection range.
Adjust the sensor (detection area) angle for
correct detection.
Select the "Application" and "Angle"
according to the installation location, and
adjust the parameters.
Increase Hold timer.
Reduce Main or Close range sensitivity.
Set Relay response time longer.
The sensor may detect a crowd. Take
measures to from entering the from
entering the area.
