Possible Causes
Electrical noise on power supply, Loose control wiring or poor grounding, Faulty speed sensor in motor, Interference from external automation signals
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing control wiring.
- Check grounding: Ensure the Kripsol pump and control panel are properly grounded and that ground connections are tight.
- Inspect control cables: Tighten all low-voltage control and communication terminals. Keep control cables separated from high-voltage power cables where possible.
- Test in standalone mode: Disconnect external automation and run the pump in local/manual mode. If speed stabilizes, the issue lies with the external controller or wiring.
- Sensor/drive fault: If fluctuations persist in standalone mode, the internal speed sensor or drive electronics may be faulty and require replacement.
