Frequently Asked Questions
Q1: Pump stops with "PID feedback loss" fault despite new pressure
sensor?
Check sensor wiring using shielded cable away from power lines.
Adjust PID parameters: increase proportional gain to 3.0-3.5,
extend integral time to 10-15s. Enable PID feedback loss protection
delay (3s). Consider adding signal isolator for unstable grids.
Q2: Overtemperature fault in Dubai hotel AC application?
Improve ventilation and relocate inverter away from heat sources.
Clean heat sink from dust accumulation. Enable controllable cooling
fan function. Install exhaust fan if needed for better heat
dissipation.
Q3: Mixer jolts violently during startup despite soft start?
Switch to "constant torque load" macro and adjust acceleration time
to 5-8s. Enable motor noise smoothing function. Check mechanical
transmission components for issues.
Q4: Inverter won't start after thunderstorm with no fault code?
Likely surge protection circuit damage from lightning. Check
internal fuse and replace if needed. Install 2P surge protector at
power input and ensure proper grounding (≤4Ω resistance).
Q5: Random pump switching and pressure fluctuations in cascade
control?
Set reasonable pressure difference band (0.2-0.3MPa) and pump start
delay (10-15s). Enable pump rotation function. Relocate pressure
sensor 3-5m from pump outlet for stable feedback.
