TROUBLESHOOTING
The sensor power is off.
Check the wiring and the power supply.
The door opens
and closes
constantly.
The sensor does not
unlock and the red
LED flashes quickly.
The sensor does
not respond to the
remote control.
The infrared power emission
is too low according to the
mounting height.
The sensor is disturbed
by the door motion or
vibrations caused by the
door motion.
The sensor needs an access
code to unlock.
The remote control
batteries are weak or
improperly installed.
Step out of the detection field and launch a
new setup.
Possible target size too large.
Check the batteries and change them
if necessary.
Make sure the detection mode is unidirectional.
Increase the detection filter value.
The door remains
closed and the LED
is OFF.
The infrared sensor
does not react.
Make sure the sensor is anchored properly.
Make sure the detection mode is unidirectional.
Change the sensor angle and/or radar angle.
Increase the detection filter value.
Reduce the field size.
Enter the correct access code.
If you do not know the access code, refer to
page 3 and delete an unknown code.
Change the antenna angle.
Decrease the field size.
Increase the detection filter value.
The door opens for
no apparent reason.
The sensor detects raindrops
or vibrations.
In highly reflective
environments, the sensor
detects objects outside of its
detection field.
The vehicle detection
filter is used, but
pedestrians are still
detected.
The chosen value is not
optimal for the application.
Increase the detection filter value.
Change the sensor angle.
Increase the mounting height.
The sensor is not installed
properly.
Fasten the sensor firmly.
Fasten the sensor firmly.
Sporadic presence
detections for no
reason.
The presence detection is
disturbed by rain or external
environment.
The sensor is not installed
properly.
Set the AIR-curtain immunity to value 3. Refer
to page 7.
The setup lasts more
than 30 seconds.
Another sensor causes
interferences.
Make sure the detection field is clear and
launch a new setup.
The red LED is
permanently ON
after a setup.
The sensor has failed the
AIR-setup.
Step out of the detection field and launch a
new setup.
The remote control is
poorly aimed.
Aim the remote control towards the sensor.
The sensor is not powered.
Check the power supply of the sensor.
Refer to page 7 and select a different frequency
for each sensor.
The setup is disturbed.
Lower the mounting height
The door never closes
and the red LED
is on.
Objects in the AIR detection
area.
Move objects or reduce automatic learn time.
Wait for learn time to expire and/or Launch a
setup.
