VPB bad teach-in.
Learning position outside the
curtain.
Relearn the VPB in the correct area.
Learning position is far away
from the sensor, or learning
object is too small.
Select a position near the sensor, or relearn the
VPB with a more significant object.
VPB can not trigger door
opening.
Approach the VPB from the
side.
Reach forward from the front to trigger the button.
The size of VPB is set too small.
Appropriately increase the VPB size.
The output delay time is set
too long.
Set a appropriate output delay time.
The learning position of the
VPB is incorrect.
Relearn the VPB in the appropriate position.
The output reset is incorrect.
Set correct output reset.
The door triggers
opening but can not
close as expected.
If the red LED is ON, a object
trigger the safety area.
Remove the object in the curtain, or start the
safety area teach-in.
If the green LED is ON, VPB is
set and trigger the long push
function.
Quick push VPB or set a correct long push time.
The RED LED is
ON sporadically or
permanently and the
door does not react
as expected.
Bad teach-in.
Launch a new safety field teach-in.
Unwanted detections
(due to environment or
external conditions).
1
Make sure the laser curtain at the correct position.
2
Verify if the laser window is dirty and clean it
carefully with a damp and clean microfibre cloth if
necessary (attention: the surface of the laser window
is delicate).
3
Switch DIP 2 to off (critical environment).
The sensor does not react
at power-on.
Inverted power supply.
Check wiring (green +, brown -).
Faulty cable.
Replace cable.
Faulty sensor.
Replace sensor.
The sensor does not react
when powered.
Test error.
Check voltage between red and blue wires.
The service mode is
activated.
Exit the service mode.
It is not possible to adjust
a setting with the remote
control.
Wrong DIP-switch position.
Adjust the required DIP-switches to ON.
The sensor is password
protected.
Enter the right password. If you forgot the code,
cut and restore the power supply to access the sen-
sor without entering a password during 1 minute.
TROUBLESHOOTING
In case of unwanted reactions of the door, verify whether the sensor or the controller causes the problem.
To do so, activate the service mode (no safety) and launch a door cycle. If the door cycle is complete successfully,
check the sensor. If not, verify the door controller or the wiring.
