Troubleshooting - BEA LZR-FLATSCAN W Manual

TROUBLESHOOTING

In case of unwanted reactions of the window, verify whether the problem is caused by the sensor or the control.
To do so, activate service mode (no safety) and cycle the window. If the window opens and/or closes, check the
sensor. If not, verify the control or the wiring.

75.0050.01 LZR-FLATSCAN W 20230908
Unwanted detections
(due to environment or
external conditions)
Inverted power supply
Faulty cable
Faulty sensor
Test error
The service mode is
activated.
Standby mode is activated.
Wrong DIP switch position.
Sensor is password-protected
The sensor encounters a memory
problem.
DIP switch setting awaiting
confirmation.
The sensor signals an
internal fault.
Power supply is out of limit.
Internal temperature is too high.
Communication error
Something close to the sensor is
masking
part of the detection field.
Teach-in error
Make sure the flexible cable does not cause
detections.
Has there been changes in the environment?
New objects?
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)
Launch a new teach-in.
Switch DIP 2 to off (critical environment).
Check wiring (green +, brown -).
Replace cable.
Replace sensor.
Check wiring between red and blue wires.
Press the push button during at least 3
seconds to exit the service mode.
Check wiring between red and blue wires.
Adjust the required DIP switches to ON.
Enter the access code. If you have forgotten
the acceess code, cut and restore the power
supply to access the sensor without an access
code within 1 minute.
Replace sensor.
Corfirm the DIP switch setting: long push on
the push button.
Cut and restore power supply.
If orange LED flashes again, replace sensor.
Check power supply (voltage).
Reduce the cable length or change cable.
Protect the sensor from any heat source (sun,
hot air, etc).
Check internal wiring between interface card
and laser head.
Make sure the laser window is not scratched.
If it is, replace sensor.
Remove all masking elements (insects, spider
web, window protection).
Verify if the laser window is dirty and clean
it carefully with a damp and clean microfiber
cloth if necessary (attention: the surface of
the laser window is delicate)
Check whether all teach-in requirements
are fulfilled (see page 8) and launch a new
teach-in.
Adjust the tilt angle of the laser curtain and
launch a new teach-in.
