SYMPTOMS
POSSIBLE CAUSES
CORRECTIVE ACTION
Red LED flashing quickly after an assisted
setup.
The sensor ‘sees’ the door movement and
can not finish its setup.
Adjust the position of the IR curtains.
Orange LED permanently ON after an
assisted setup.
The sensor encounters a signal saturation.
Use the wide-field prism and/or slightly increase the IR curtains angle
(turning the screw counterclockwise).
Red LED permanently ON after an assisted
setup.
The sensor fails the IR test.
Cut and restore the power supply.
Launch a new assisted setup.
If the LED still stays ON, replace the sensor.
Orange LED ON
The sensor encounters a signal saturation.
Use the wide-field prism and/or slightly increase the IR curtains angle
(turning the screw counterclockwise).
Launch an assisted setup.
Orange LED flashes
The sensor signals an internal fault.
Cut and restore the power supply.
If the orange LED lights up again, replace faulty sensor.
Red LED ON
The sensor detects a presence.
Wait the time set in “maximum duration of presence detection” setting
or launch an assisted setup (with the remote control or right push
button).
Unwanted presence detection
The sensor is not placed properly
and/or the front face is not properly fixed.
Fasten the sensor firmly and/or
check whether the front face prism is placed into the foreseen slides
(see section 6) and not in the sensor cover.
Door keeps recycling open-closed.
The sensor is disturbed by the door motion
because it sees the door or because of
vibrations.
Green LED signals a motion detection : increase the radar angle
Red LED signals infrared detection : increase the IR curtains angle
(turning the screw counterclockwise).
The door is not closing.
LED OFF
On-Off switch at door control is in wrong
position or is faulty.
Check to insure that On-Off switch for door is in the ON or
AUTOMATIC position.
Improper output configuration on the sensor. Check the output configuration setting on each sensor.
Faulty sensor monitoring of the door
controller.
Check if the monitoring mode is ON or PULSE depending on the door
controller. Check the wiring.
After a power on, there is no LED-signal,
even during a motion detection.
The motion output is active and the presence
output is fixed.
The sensor’s monitoring input is not correctly
supplied.
Check the wiring and the power supply (voltage and polarity) of the
monitoring input.
Disable the monitoring of the sensor if the door operator cannot monitor
the sensor.
The door closes slowly.
LED OFF
Faulty sensor monitoring of the door
controller.
Check if the monitoring mode is ON or PULSE depending on the door
controller. Check the wiring.
The presence detection is disturbed by the
rain (red LED)
Increase the immunity of the curtains (immunity 3 up to 5)
The radar detection is disturbed by the rain
(green LED).
Check whether the unidirectional mode is selected and the MTF
function is disabled. Increase the radar immunity.
The sensor does not unlock when access
code is entered.
Improper code being entered.
Cut and restore power supply. No code is required to unlock during the
first minute after powering. Press on “unlock”, then on “lock” and
introduce a new access code.
The sensor does not respond to the remote
control.
1. Batteries in the remote control are dead or
not installed properly.
2. Remote control badly pointed.
1. Check to insure that the batteries are installed correctly or replace
batteries.
2. Point the remote control towards the sensor.
