LED indicators provide real-time fault alerts, ensuring quick troubleshooting.
Key Installation Guidelines
- Mount horizontally only (±5° tolerance) – *Never install vertically!*
- Rotate the terminal box 90° if needed for wiring convenience
- Use included gaskets & O-rings for leak-free sealing
- Tighten screws diagonally to prevent uneven pressure on flanges
⚠ Critical Pre-Startup Checks
1. Always ground the pump for electrical safety.
2. Connect an external power switch for easy control.
3. Open valves and purge air from pipes before first use.
4. Avoid overtightening screws to prevent flange damage.
Control Modes & Gear Adjustment
- Button 1 – Switches between Auto, Constant Speed, Proportional, Constant Pressure, and Temp Control modes.
- Button 2 – Adjusts gear settings (default: Gear 3).
- In Temperature Control Mode, press to cycle through Gears 4-10.
Fault Indications (LED Flashing Patterns)
| Flashes | Protection Mode | Action Required |
| 1 Flash | Overvoltage | Restart after voltage stabilizes |
| 2 Flashes | Undervoltage | Restart after voltage recovers |
| 3 Flashes | Overcurrent | Auto-restart after 8s (5 attempts) |
| 4 Flashes | Phase Loss | Check wiring, then restart |
| 5 Flashes | Locked Rotor | Auto-restart after 8s (5 attempts) |
| 6 Flashes | Light Load | Verify load compatibility |
| 7 Flashes | Overtemperature | Cool down before restarting |
