4. Persediaan dan Pemasangan

4.1 Pemasangan

• Mount the valve in an accessible location for maintenance and inspection.
• Ensure adequate clearance for wiring and actuator removal.
• The valve can be mounted in any orientation, but it is recommended to avoid mounting with the actuator below the valve body to prevent condensation issues.

4.2 Piping Connections

• Ensure the piping system is clean and free of debris before installing the valve.
• Connect the valve to the piping using appropriate fittings for 1.25-inch connections.
• Apply pipe sealant or Teflon tape to threaded connections to prevent leaks.
• Observe flow direction indicators on the valve body, if present, for correct installation in mixing or diverting applications.

4.3 Pendawaian Elektrik

Awas: Disconnect power before performing any wiring procedures.

• The actuator requires a 24V AC/DC power supply. Connect the power wires to the designated terminals on the actuator.
• Connect the 2-10V DC control signal wires to the appropriate input terminals.
• Ensure all wiring complies with local electrical codes and standards.
• Refer to the wiring diagram provided with the product for specific terminal assignments.

5. Arahan Operasi

The Belimo B330+AFRB24-SR valve operates based on a 2-10V DC proportional control signal. The actuator modulates the valve position in response to this signal.

• Control Signal (2-10V DC):
  • A 2V signal typically corresponds to the minimum flow position (e.g., port A fully open, port B fully closed for mixing).
  • A 10V signal typically corresponds to the maximum flow position (e.g., port B fully open, port A fully closed for mixing).
  • Jilid pertengahantage signals (e.g., 6V) will position the valve proportionally between these extremes.
• Spring Return Function: In the event of power loss, the spring return mechanism will automatically move the valve to a pre-defined safe position (e.g., fully open or fully closed on a specific port, depending on configuration).
• Pembatalan Manual: Some actuators may include a manual override lever or button. Consult the actuator's specific documentation for details on manual operation.

6. Penyelenggaraan

The Belimo B330+AFRB24-SR valve and actuator are designed for long-term, maintenance-free operation under normal conditions. However, periodic checks are recommended.

6.1 Pemeriksaan Rutin

• Pemeriksaan Visual: Periodically inspect the valve and actuator for any signs of leaks, corrosion, or physical damage.
• Actuator Operation: Observe the actuator's movement to ensure it responds smoothly and accurately to the control signal.
• Sambungan: Check electrical and piping connections for tightness and integrity.

6.2 Pembersihan

Clean the exterior of the valve and actuator with a damp cloth. Do not use abrasive cleaners or solvents that could damage the materials.
