Installation Guide

1. Preparation

1. Disconnect Power: Ensure the main power supply to the gate opener control unit is disconnected before starting.
2. Identify Mounting Location: Determine the optimal position for the magnetic limit switch and magnets on the gate and its structure. The switch should be mounted on the fixed part of the gate structure, and the magnets on the moving gate leaf.
3. Tools Required: Gather necessary tools including a drill, screwdriver set, measuring tape, and level.

2. Mounting the Magnetic Limit Switch

1. Position the MC775 limit switch unit on the gate's fixed support structure. Ensure it is level and securely fastened using the provided mounting brackets and screws.
2. The switch should be positioned such that the magnets, when mounted on the gate leaf, will pass directly over the sensor area of the switch at the desired open and closed positions.

3. Mounting the Magnets

1. Mount one magnet on the gate leaf at the position where the gate should fully open. This magnet will trigger the "open" limit.
2. Mount the second magnet on the gate leaf at the position where the gate should fully close. This magnet will trigger the "close" limit.
3. Ensure the magnets are aligned with the sensor area of the limit switch and are within the effective sensing range (typically a few millimeters to a centimeter, refer to control unit manual for exact specifications).

4. Wiring the Limit Switch to the Control Unit

Refer to the specific wiring diagram in your ROGER TECHNOLOGY control unit manual (H70/103AC, H70/104AC, B70/1DC, B70/1DCHP) for precise connection points. Generally, the magnetic limit switch will connect to dedicated "OPEN LIMIT" and "CLOSE LIMIT" terminals on the control board.

• Connect the wires from the MC775 switch to the corresponding terminals on the control unit. Pay close attention to polarity if specified.
• Secure all connections and ensure no bare wires are exposed.

5. Initial Testing and Adjustment

1. Reconnect Power: Carefully reconnect the main power supply to the control unit.
2. Test Gate Movement: Operate the gate manually or via the control unit to observe the interaction between the magnets and the limit switch.
3. Adjust Magnet Positions: If the gate does not stop at the desired open or closed positions, adjust the magnet positions slightly until the correct stopping points are achieved. The magnets should trigger the switch precisely at the full open and full closed positions.
4. Verify Functionality: Perform several full open and close cycles to ensure consistent and reliable operation of the limit switches.

Operation

Once installed and configured, the MC775 Magnetic Limit Switch Kit operates automatically in conjunction with your ROGER TECHNOLOGY control unit. The magnets mounted on the gate leaf will activate the switch when the gate reaches its fully open or fully closed position, signaling the control unit to stop the motor. This ensures precise and repeatable gate positioning.

• The "open" magnet triggers the switch to signal the gate is fully open.
• The "close" magnet triggers the switch to signal the gate is fully closed.
• The control unit interprets these signals to manage motor operation and prevent over-travel.

Maintenance

The MC775 Magnetic Limit Switch Kit is designed for low maintenance. However, periodic checks are recommended to ensure optimal performance and longevity.

• Visual Inspection (Monthly): Check the limit switch and magnets for any signs of physical damage, corrosion, or loose mounting.
• Cleanliness: Ensure the area around the limit switch and magnets is free from dirt, debris, or obstructions that could interfere with their operation.
• Wiring Check (Annually): Inspect the wiring connections to the control unit for any signs of wear, fraying, or loose terminals.
• Functionality Test (Quarterly): Manually operate the gate to its full open and closed positions to confirm that the limit switches are activating correctly and stopping the gate precisely.
