3.1 Wiring Diagram (CR03 Model)
The AC220V_CR03 model uses a three-wire one-control mode. Refer to the diagram below for correct wiring.
Image 3.1: Wiring diagram for CR03 models (AC220V, DC12V, DC24V). It illustrates the connection of the brown, blue, and yellow lines from the actuator to an external controller with a switch (SW).
Wiring Instructions:
- Connect the Brown line to one side of the power supply and the switch (SW).
- Connect the Blue line to the other side of the power supply.
- Connect the Yellow line to the switch (SW) to control the valve's state.
Operation based on SW state:
- When SW is closed, the valve opens. The internal automatic power-off function activates once fully open, and the valve remains in the fully open position.
- When SW is disconnected, the valve closes. The internal automatic power-off function activates once fully closed, and the valve remains in the fully closed position.
Warning: Ensure all electrical connections are secure and comply with local electrical codes. Incorrect wiring can damage the device or cause electrical hazards.
4. Operating Instructions
Once installed and wired correctly, the valve's operation is controlled by the external switch (SW) as described in the wiring section.
- To open the valve, close the control switch (SW). The valve will automatically open within 5-15 seconds and then power off, holding its open position.
- To close the valve, open (disconnect) the control switch (SW). The valve will automatically close within 5-15 seconds and then power off, holding its closed position.
The valve is designed for intermittent operation, consuming power only during the opening or closing cycle.
5. Maintenance
The JJCEQBPE Motorized Ball Valve is designed for low maintenance. Regular checks can ensure optimal performance and longevity.
- Visual Inspection: Periodically inspect the valve and connections for any signs of leaks, corrosion, or physical damage.
- Electrical Connections: Ensure all wiring connections remain secure and free from moisture or damage.
- Cleaning: If installed in a dusty or dirty environment, gently clean the exterior of the actuator and valve body with a damp cloth. Do not use abrasive cleaners or solvents.
- Operational Check: Occasionally cycle the valve (open and close) to ensure smooth operation.
Caution: Always disconnect power before performing any maintenance or inspection.
6. Troubleshooting
If you encounter issues with your motorized ball valve, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not open/close | No power; Incorrect wiring; Motor malfunction; Obstruction in valve | Check power supply; Verify wiring against diagram (Image 3.1); Inspect for obstructions; Contact support if motor is faulty. |
| Valve leaks | Improper installation; Damaged seals; Incorrect thread sealant | Ensure connections are tight and properly sealed; Inspect seals for damage; Reapply thread sealant if necessary. |
| Valve operates slowly | Low voltage; Internal friction | Verify power supply voltage matches valve requirements; Cycle valve a few times to see if operation improves. |
For issues not listed here or if solutions do not resolve the problem, please contact the manufacturer's support.
