Symptom Cause Action
Main or close range sensitivity is too high. Reduce Main or Close range sensitivity.
Relay response time is too short. Increase Relay response time.
The metal object or baggage is too large.
The sensor may not discriminate between
large objects and vehicles. Take measures to
prevent large groups of people from entering the
area.
Main or Close range sensitivity is too low. Increase Main or Close range sensitivity.
Relay response time is too long. Shorter Relay response time
The detection range may be too short. Increase the detection range.
"Application" selection is incorrect.
Check that selected “Application” matches
the installation condition.
Main or Close range sensitivity is too low. Increase Main or Close range sensitivity.
Sensitivity boost timer is disabled. EnableSensitivity boost timer
Sensitivity boost timer is set too short. Set Sensitivity boost timer longer.
Main or Close range sensitivity is too high. Reduce Main or Close range sensitivity.
The detection range is too long.
At the front edge of the detection area, a vehicle
in the opposite lane may be detected. Adjust the
detection range so that the front edge of the
detection area does not reach the opposite
lane.
The angle of the sensor (detection area)
is not correct.
Adjust the angle (detection area) of the sensor
to be parallel to the barrier arm.
A vehicle in the opposite lane is approaching
slowly.
A vehicle approaching slowly in the opposite
lane is likely to be detected.
Main or Close range sensitivity is too high. Reduce Main or Close range sensitivity.
The detection range is too long. Reduce the detection range.
Installation position of the sensor is too close
to the barrier arm.
Install the sensor 300mm (12in.) away
from the barrier arm.
The angle of the sensor (detection area) is not
correct.
Adjust the angle (detection area) of
the sensor to be parallel to the barrier arm.
The barrier arm has a curtain attached. Remove the curtain.
If you still can't solve the problem even after following the instructions above, contact our technical support or sales representative or sales office.
Please contact your dealer for the warranty period.
The sensor detects a pedestrian with large
baggage or a metal object passing through
the detection area.
Sensor's response is too slow. It should
detect earlier (start detecting at a further
distance).
A vehicle is not detected when re-backing up
into the detection area.
A vehicle in the opposite lane is detected.
(Application : Barrier Protection / Activation)
The barrier arm is detected.
The barrier arm re
peatedly opens and closes.
