- Ensure the valve is in its fully closed or fully open position before mounting.
- Align the actuator's shaft coupling with the valve stem.
- Secure the actuator to the valve using the appropriate mounting hardware. Refer to the specific valve's documentation for torque specifications.
- Verify that the actuator can move freely through its full range of motion without obstruction.
ഇലക്ട്രിക്കൽ വയറിംഗ്
The GRX24-MFT-T operates on 24V AC/DC. Refer to the wiring diagram provided with the actuator or on the product label for specific connections. Ensure all wiring complies with local electrical codes.
- വൈദ്യുതി വിതരണം: Connect the 24V AC/DC power supply to the designated terminals.
- നിയന്ത്രണ സിഗ്നൽ: Connect the control signal (e.g., 0-10V, 2-10V, 4-20mA) to the appropriate input terminals.
- Feedback Signal: If feedback is required, connect the feedback output (e.g., 0-10V, 2-10V) to the control system.
- ഗ്രൗണ്ടിംഗ്: Ensure proper grounding to prevent electrical hazards and interference.
For detailed wiring diagrams and MFT configuration options, consult the official Belimo GRX24-MFT-T technical documentation or the Belimo webസൈറ്റ്.
പ്രവർത്തന നിർദ്ദേശങ്ങൾ
പ്രാരംഭ പവർ-അപ്പ്
- After completing installation and wiring, apply power to the actuator.
- The actuator will typically perform a self-calibration or move to a default position. Observe its initial movement.
യാന്ത്രിക പ്രവർത്തനം
The GRX24-MFT-T actuator operates automatically based on the control signal received from the building management system (BMS) or controller. It will modulate the valve position to maintain the desired flow or pressure.
Manual Override (if applicable)
Some models may include a manual override feature. If present, follow these steps:
- Disconnect power to the actuator before engaging manual override.
- Engage the manual override mechanism (e.g., push button, lever, or crank).
- Manually adjust the valve position as needed.
- Disengage the manual override and restore power for automatic operation.
മെയിൻ്റനൻസ്
The Belimo GRX24-MFT-T actuator is designed for maintenance-free operation under normal conditions. However, periodic checks are recommended to ensure optimal performance and longevity.
- വിഷ്വൽ പരിശോധന: Periodically inspect the actuator for any signs of physical damage, corrosion, or loose connections.
- വയറിംഗ് സമഗ്രത: Check electrical connections for tightness and ensure insulation is intact.
- മൗണ്ടിംഗ് സെക്യൂരിറ്റി: Verify that the actuator remains securely mounted to the valve.
- പരിസ്ഥിതി വ്യവസ്ഥകൾ: Ensure the operating environment remains within the specified limits (e.g., temperature, humidity).
Do not attempt to open the actuator housing, as this may void the warranty and expose internal components to damage.
