1
Check cable and connexion.
Check the polarity of the power supply.
1
1
Activate the LEDs by remote control.
1
Check wiring.
The BLUE and BLUE/WHITE cable have to be

1
Check the size of the fields.
2
Launch a teach-in.
1
Decrease the min. object size.
1
Step out of the field and/or remove the any
object(s) from the field and launch a teach in.
1
Activate the 3 red beams and check if the
position of the sensor is correct.
If not, adjust the hex screws.
2
Verify the field size.
3
Launch a teach-in.
1
Check the position of the sensor.
Check the mounting side setting.
2
If there is no background, set the mounting side
to value 3 to 5.
Launch a new teach-in.

1
Verify and clean the front screens
with a damp cloth.
1
Check the power supply voltage.
1
Verify the outside temperature where the sensor
is installed. Eventually protect the sensor from
sunlight using a cover.
1
Wait a few seconds.
If the LED remains ON, reset the power supply.
If the LED turns on again, replace the sensor.
1
Cut and restore power supply.
The remote control session is accessible again
during 30 minutes.
1
Verify or replace the batteries.
1
Point the remote control towards the sensor, but
with a slight angle. The RC should not be
pointed in a right angle in front of the sensor.
Avoid highly reflective material in proximity to
1
the sensor.
1
Cut and restore power supply.
No code is required to unlock during the first
minute after powering.
