4. Postavljanje i instalacija

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

4.1 Montaža

1. Osigurajte damper shaft is clean and free of obstructions.
2. Gurnite aktuator na damper 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 Ožičenje

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 prije primjene struje.

5. Uputstvo za upotrebu

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. Održavanje

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

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