FOREWORD

The FLATS CAN 3D SW can be paired with another FLATS CAN 3D SW or a FLATS CAN SW. The installation steps are identical for both product versions. For optimum safety and to access all features (e.g. opening functions), the FLATS CAN 3D SW must be the primary sensor.

MOUNTING ON DOOR

For applications requiring a spacer, first mount spacer to door, and then mount mounting base to spacer.

1. Slide the base off the sensor.

2. Position the mounting base on the door. Use the positioning tabs to align the base correctly.
   When mounting the base, make sure the sensor will not interfere with door movement. If the sensor isn’t correctly positioned, it could be damaged during the opening/closing of the door. Things to observe: distance from pivot edge, distance from top of door, frame clearance, finger guard, door arm, etc.

3. Mark the pilot holes on the door. You can also use the inner surface of the mounting base to fasten the screws.

4. Remove the base and drill 1⁄8″ pilot holes.

5. Using a wire cutter, remove the positioning tabs from the base.

6. Fasten the 3 screws using a screwdriver. The base must be secure!

7. Drill through the 2 bases and the door using a 5⁄16″ drill bit in order to pass the primary-secondary cable. Soften the edges using sandpaper.

8. Pass the primary-secondary cable through the hole and then position the cable in the notch of the base and ensure it is secure.

9. Pass the cable through the hole on the back of the sensor and secure the sensor to the base by sliding it down.

10. Connect the black plug to the black connector. Ensure that all wires are secured within the notch to avoid damage from the cover.

11. Use a plug to close the secondary sensor.

12. Secure the lock screw to avoid vibrations during door movement.

WIRING TO DOOR CONTROLLER

BEA recommends using a FLATSCAN 3D SW as the primary sensor.

1. Determine the appropriate length for the door loop.
2. Cut the excess to avoid undesired detections caused by the flexible tube.
3. Pass the power cable through the flexible tube and connect the white plug to the white connector.
4. Create a loop with the wires of the power cable and pass them through the notch as indicated. Use the other part of the cable to block the wires.
5. Secure the door loop to the sensor, using the clamp. Secure the 2 screws to avoid pulling out the cable.
6. Tighten the other side of the flexible tube using the cable cap and pass through the remaining length of the power cable towards the door controller.

WIRING: CABLES

Cut the power cable to the correct length, strip the 10 wires, and connect all wires as indicated. Observe polarity.

1.  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.
2. Output status when sensor is operational (can be NO or NC; NO = default). See page 10.
3. Knowing-act door and control does not have secondary activation. Use a BR3-X (function 22) and LE21.
4. O3 is only operational when the gray wires of the FLATSCAN 3D SW are connected to activation on the door controller, from the primary sensor.

DIP SWITCH

TEACH-IN

Before launching a teach-in, make sure that:

• glass surfaces near the door are covered
• when a guide rail is involved in the application, an object should be placed between the full-open door and guide rail to create a larger reference point for the learn
• the door controller is set up first
• the door is closed (use Service Mode if needed, see page 13)
• the door controller is connected to all relay outputs and is fully reacting to them
• Output Configuration is set correctly (see page 10)
• the primary-secondary cable is connected between the modules
• the detection field is free of snow buildups, heavy rain, snowfall, fog, or other objects or people
• the laser window protection is removed (for FLATS CAN SW)

NOTE: A teach-in on the Primary configures both the Primary and the Secondary. A teach-in on the Secondary only configures the Secondary. In case the Primary and Secondary sensor are not aligned, first launch a teach-in on the Primary and then on the Secondary.

BEA recommends setting the sensor in Service Mode before performing a teach-in (see page 13).

1. Press the Primary sensor push-button briefly. The LED will begin quickly flashing red/green. When installing the sensor on a pair of doors, repeat this on the second Primary sensor.
2.  When both sensors flash green, position yourself in front of the door(s) and stretch out your arm in front of you. Make an up-and-down motion at the leading-edge to mark the limit of the detection zones. Once the LED begins flashing red, remove yourself from the detection zone. The LED will continue to flash red while calculating the width of the door leaves.
3. When the sensors flash green again, remain out of the detection field and cycle the doors open to allow the sensors to learn the environment. The sensors will flash red during the closing of the door(s).
4. Once the door is completely closed again and the LED is off, the teach-in is complete.

TESTING AND ADJUSTING

• Check the correct positioning of the safety fields by walk-testing according to ANSI 156.10 standards.
• If necessary, adjust the tilt angle of the laser curtain by turning the tilt angle adjustment screw (from 0° to 5°)

After changing the angle, the sensor position or the environment, always launch a teach-in and test the correct positioning of the detection fields. Verify that the sensor system complies with ANSI 156.10 per the AAADM walk test. Make appropriate adjustments to the sensor and/or door control, if necessary, to ensure that the system is ANSI 156.10 compliant.

VIRTUAL PUSH BUTTONS

Always verify compliance with ANSI 156.10, 156.19, and 156.38. If desired and in addition to ANSI 156.10, 156.19, and 156.38 Knowing Act requirement, you can add a Virtual Push Button option (max. 2 per sensor) within the second (C2) curtain simulating the performance of a knowing-act device. The Virtual Push Button(s) may be placed outside of the detection field but within a limit of maximum detection field range specifications. To operate, the two gray wires of the FLATSCAN 3D SW must be connected (as the primary sensor) to the activation on the door controller with the 10-wire cable provided.

1. When the green LED flashes, hold your hand in the desired position within C2 to learn the Virtual Push Button.
2.  When the LED flashes red to confirm the teach-in, remove yourself and hand.
3. When the LED flashes green again, you can either learn another Virtual Push Button or wait 10 seconds for the end of the teach-in.

FINAL STEPS

• CLOSING
  • Close the cover starting on the narrow side. Do not hesitate to push.
• OPENING
  • To remove the cover, position a flathead screwdriver in the notch and pull upward until the cover loosens.

DIP SWITCH SETTINGS (OPTIONAL)

In order to adapt these parameters by remote control, set the corresponding DIP switch to ON. Switch to CRITICAL when external disturbances are likely to cause unwanted detections (min. obj size, immunity, and uncovered zone are increased). Switch to OFF when there is no background (glass floor, Pedi-mat, etc). Switch to OFF when the pinch zone does not need to be secured or when objects can cause unwanted detections. After changing a DIP switch, the orange LED flashes. A LONG push on the push button confirms the settings. Afterward, a number of green flashes (x) indicates the number of connected modules.

REMOTE CONTROL SETTINGS (OPTIONAL)

HOW TO USE THE REMOTE CONTROL

• 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.
  SAVING AN ACCESS CODE

  • The access code is recommended for sensors installed close to each other.

• DELETING AN ACCESS CODE

  • Enter the existing code

• ADJUSTING ONE OR MORE PARAMETERS

• CHECKING A VALUE

• RESTORING TO FACTORY VALUES

DETECTION FIELDS

• DOOR LEAF SAFETY
• PINCH ZONE SAFETY
• UNCOVERED ZONE adjustable by remote control factory value: 4 in

SERVICE MODE

Service Mode deactivates all detection fields for 15 minutes and can be useful during an installation, a mechanical learn of the door, or maintenance work.

• To enter Service Mode, push and hold the button for at least 3 seconds. The LED will turn off.
• To exit Service Mode, push and hold again for at least 3 seconds.

Service Mode is deactivated automatically when a teach-in is launched.
