5. Setup and Installation
Follow these steps for proper installation of the JD-5 Motor Overload Protector Relay:
- Power Disconnection: Ensure all power to the motor and control circuit is completely disconnected and locked out before beginning installation.
- Mounting: Mount the JD-5 relay securely in a suitable enclosure or panel, ensuring adequate ventilation. The device has mounting brackets on the sides.
- Wiring Connections: Connect the motor power lines through the designated terminals on the relay. Refer to the wiring diagram printed on the device or in the detailed manual for specific connections. Ensure all connections are tight and secure. The device supports both AC380V and AC220V operation.
- Current Setting: Adjust the current setting knob (labeled "电流整定" - Current Setting) to match the rated current of the motor being protected. This is typically found on the motor's nameplate.
- Delay Time Setting: Adjust the delay time knob (labeled "延时整定" - Delay Setting) according to the motor's starting characteristics. A longer delay may be needed for motors with high inrush currents during startup.
- Verification: Double-check all wiring connections and settings before restoring power.

6. Operating Instructions
Once installed and configured, the JD-5 relay operates automatically to protect the motor. Observe the indicator lights for operational status:
- "运行" (Run) Indicator: Illuminates when the motor is operating normally.
- "过载" (Overload) Indicator: Flashes or illuminates steadily when an overload condition is detected. The relay will trip after the set delay time.
- "断相" (Phase Loss) Indicator: Illuminates when a phase loss condition is detected. The relay will trip immediately.
In case of a trip, identify and resolve the fault condition before resetting the relay and restarting the motor.
7. Maintenance
The JD-5 Motor Overload Protector Relay requires minimal maintenance. Regular checks include:
- Visual Inspection: Periodically inspect the relay for any signs of physical damage, loose connections, or excessive dust accumulation.
- Cleaning: If necessary, gently clean the exterior of the device with a dry, soft cloth. Do not use liquid cleaners.
- Connection Check: Ensure all wiring terminals remain tight and secure to prevent intermittent operation or arcing.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Relay trips frequently | Motor overload, incorrect current setting, motor fault, or insufficient delay time. | Check motor load, verify current setting matches motor nameplate, inspect motor for issues, or slightly increase delay time if tripping during startup. |
| "断相" (Phase Loss) indicator on | Loss of one or more phases in the power supply, loose wiring connection. | Check power supply phases, inspect all wiring connections to the relay and motor for tightness. |
| Relay does not trip on overload | Current setting too high, faulty relay. | Reduce current setting to match motor rating. If problem persists, the relay may be faulty and require replacement. |
| No indicators light up | No power to the relay, incorrect wiring. | Verify power supply to the relay and check all wiring connections according to the diagram. |
