INSTALLATION TIPS

BEA-LZR-FLATSCAN-W-Safety-Sensor-for-Automated-
Windows-fig-7

Remove the laser window protection before teach-in and commissioning.
Avoid vibrations.
Do not cover the laser window.
Avoid moving objects and light sources in the detection field.
Avoid the presence of smoke and fog in the detection field.
Avoid condensation.
Avoid exposure to sudden and extreme temperature changes.
Ensure power to the sensor in areas where the temperature can reach below -10 °C.

MAINTENANCE TIPS

BEA-LZR-FLATSCAN-W-Safety-Sensor-for-Automated-
Windows-fig-9

When needed, wipe the laser window only with a soft, clean, and damp microfiber cloth.
Do not use dry or dirty towels or aggressive products to clean the laser window.
Avoid direct exposure to high-pressure cleaning.
The warranty is invalid if unauthorized repairs are made or attempted by unauthorized personnel.

SAFETY TIPS

The door control unit and the header cover profile must be correctly grounded.
Only trained and qualified personnel are recommended to install and set up the sensor.
Always test for proper operation before leaving the premises.
Do not remove the laser window protection if building works are still in progress on site.

HOW TO USE THE REMOTE CONTROL

BEA-LZR-FLATSCAN-W-Safety-Sensor-for-
Automated-Windows-fig-10

After unlocking, the red LED flashes, and the sensor can be adjusted by remote control.
If the red LED flashes quickly after unlocking, you need to enter an access code from 1 to 4 digits.
If you do not know the access code, cycle the power.
During 1 minute, you can access the sensor without introducing any access code.
To end an adjustment session, always lock the sensor.
It is recommended to use a different access code for each sensor in order to avoid changing settings on both sensors at the same time.

SAVING AN ACCESS CODE

The access code is recommended for sensors installed close to each other . BEA-LZR-FLATSCAN-W-Safety-Sensor-for-Automated-Windows-

OPENING AND CLOSING THE SENSOR

BEA-LZR-FLATSCAN-W-Safety-Sensor-for-
Automated-Windows-fig-12

To open, insert your finger in the hole and then pull it towards you in one movement.
Close the cover starting on the narrow side (1). Do not hesitate to push (2).
To open the sensor after it has been mounted, position a screwdriver in the notch and pull upwards until the cover comes loose.
When closing, be sure to secure the cover to avoid vibrations.

WIRING

Create a loop with the wires of the power cable and pass them through the notch as indicated.
Block the cable behind the notches. You can use the flexible cable to guide the cable.
Cut the power cable to the right length, strip the 8 wires, and connect all wires as indicated.
The polarity of the power supply must be respected!
Typical compliance with safety standards requires the test output to be connected and monitored via the controller.

If only VAC power is available, a 12V transformer paired with a rectifier must be used. Do not use a 24V transformer and rectifier as this will cause damage to the product.
Output status when the sensor is operational (can be NO or NC). See page 10, OUTPUT CONFIGURATION.
If TEST is not used, apply 12 – 24 VDC to TEST wires (red and blue) to bypass.

ADJUSTING CURTAIN ANGLE

BEA-LZR-FLATSCAN-W-Safety-Sensor-for-Automated-Windows-
fig-16 If necessary, adjust the tilt angle of the laser curtain by turning the tilt angle adjustment screw.

DIP SWITCH SETTINGS

DIP 1| BACKGROUND ANALYSIS| ON| OFF| ON : The sensor analyses the background located in the detection field.

OFF : The sensor works with an uncovered zone of min. 2 cm.

---|---|---|---|---
DIP 2| IMMUNITY| standard| critical| Switch to CRITICAL when external disturbances are likely to cause unwanted detections (increased immunity).
DIP 3| OBJECT SIZE| 3 ⁄ 4 “| 2 1 ⁄ 3 “| See MIN. OBJECT SIZE setting
DIP 4| PINCH ZONE| ON| OFF| See OPTIONAL PINCH ZONE DIMENSIONS setting

After changing a DIP switch, the orange LED flashes. A LONG push on the push button confirms the settings.

TEACH-IN

Before launching a teach-in, make sure that:

the detection field is free of objects
the laser window protection cap is removed
glass surfaces near the detection zone are covered

To launch a teach-in, press the push button briefly or use the remote control (see below).
The LED will flash red/green. Wait until it slowly flashes green.
Position yourself in front of the detection field and strech out your arm in the bottom corner opposite to the sensor in order to define the limit of the detection zone.
The LED flashes red while calculating the detection zone. Once the LED is off, the teach-in is complete.

FREE SHAPE TEACH-IN

You can also set the detection field by launching a “free shape” teach-in.
The shape and limit of the detection field are defined by a slow hand movement.
You have 30 seconds to define the detection field with your hand.

VIRTUAL PUSH BUTTONS (VPB)

After either one of the previous teach-ins, you can add virtual push buttons (max. 10) in the detection field. They can be used as activation zones to open or close the window automatically:

When the green LED flashes, hold your hand in the desired position to learn the virtual push button.
When the LED flashes red to confirm the teach-in, remove your hand.
When the LED flashes green you can either learn another virtual push button or wait 10 seconds until the end of the teach-in.

HOW TO REMOVE VPBs:

Perform a VPB teach-in without putting your hand in the field.
Perform a factory reset on the sensor.
Both of these options will remove ALL established virtual push buttons. You will have to perform new teach-ins for any that you wish to remain for your application.
Launch a new teach-in each time the sensor position is changed or objects are added to or changed in the detection zone.

REMOTE CONTROL SETTINGS (OPTIONAL)

SERVICE MODE

Service mode deactivates the safety detection for 15 minutes and can be useful during an installation, a mechanical teach-in of the window, or maintenance work.
To enter service mode, press the red button for at least 3 seconds. The LED will be OFF when the sensor is in service mode.
To exit the service mode, press again for at least 3 seconds.
Service mode will automatically deactivate when a teach-in is launched.

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.
