3. Produktüberschreitungview

The Belimo LMB24-3-T is a direct-mount, non-spring return damper actuator designed for modulating control of air dampers in HVAC systems. It operates on 24VAC/DC power and provides a 0-95 degree rotation with a 45 in-lb (5 Nm) torque output. Its floating signal input allows for precise positioning.

Abbildung 1: Belimo LMB24-SR Damper Actuator. This image displays the Belimo LMB24-SR non-spring return damper actuator. The actuator is orange and grey, showing its direct mount mechanism and electrical connection block. Visible text on the actuator includes 'BELIMO', 'Made in Switzerland', 'LMB24-SR', '5Nm 45in-lb', '24VAC/DC', '150s', '2VA 1W', 'Input 2... 10V', 'NEMA2 IP54', and certification marks like UL and CE. A wiring diagram is clearly visible on the black connection block, detailing connections for COM I, RD, WH Y, OG U, PK C1, and GY C2.

4. Einrichtung und Installation

Follow these general steps for proper installation. Refer to specific wiring diagrams for your application.

4.1 Montage

1. Stellen Sie sicher, dass damper shaft is clean and free of obstructions.
2. Schieben Sie den Aktuator auf dieamper shaft. The direct mount design allows for easy attachment.
3. Secure the actuator firmly to the damper shaft using the provided hardware. Ensure the actuator is aligned correctly with the damper blade's movement.

4.2 Verkabelung

The actuator requires a 24VAC/DC power supply. The floating signal input allows for control based on the duration of the control signal. Refer to the wiring diagram on the actuator (as shown in Figure 1) for specific terminal connections.

Typical Wiring (refer to actuator label for exact pinout):

• 1 BK (Black): COM I (Common Input)
• 2 RD (Red): ~+ (Power Supply +)
• 3 WH (White): Y ~+ (Control Signal Input)
• 5 OG (Orange): U (Feedback Signal Output)
• 6 PK (Pink): C1 (Auxiliary Contact 1)
• 7 GY (Grey): C2 (Auxiliary Contact 2)

Ensure all connections are secure and insulated. Verify correct voltage vor dem Einschalten.

5. Bedienungsanleitung

The LMB24-3-T operates with a floating control signal. This means the actuator's position is determined by the duration of the control signal applied to the 'Y' input (White wire) relative to the common. The actuator will rotate to its fully open or closed position based on the signal direction and duration.

• Applying a signal to 'Y' will cause the actuator to rotate in one direction.
• Reversing the polarity of the signal (or applying a signal to an alternative input if available) will cause rotation in the opposite direction.
• Removing the signal will cause the actuator to hold its last position.
• The actuator has a mechanical stop for setting the minimum and maximum rotation limits within the 0-95 degree range.

6. Wartung

The Belimo LMB24-3-T actuator is designed for maintenance-free operation. However, periodic inspection is recommended to ensure optimal performance:

• Jährliche Inspektion: Check for any loose connections or signs of wear on the wiring.
• Reinigung: Keep the exterior of the actuator clean and free of dust or debris. Do not use abrasive cleaners or solvents.
• DampBedienung: Periodically verify that the damper operates smoothly and without excessive resistance, which could strain the actuator.
