W191 Series Intelligent Controller for Water Pump User Manual
Reason
4. bad earth
1. Speed up or slow down too
fast
2. The voltage of the grid is low
3. There are impurities in the
pump
4. Water pump plugging
1. Abnormal input voltage
2. Slow down too fast
3. Large load inertia
4. Instant power outage and then
call the impact
1. Low input voltage
1. Acc. time is too short;
2. Restart the rotating motor;
3. Low input voltage;
4. Load is too heavy
1. Low input voltage;
2. Wrong
setting
parameter;
3. 3.Motor locked-rotor or too
low load mutation;
4. The power of motor is too
small
1. Open-phase occurred at output
side of main circuit
1. Sudden over-current;
2. Input/output side has short
circuit;
3. Cooling fans of controller
blocked or damaged;
4. Ambient temperature is too
high;
