Common Alarm Codes And Solutions
Alarm code Alarm Description Possible reasons Solutions
A-01 Water shortage protection
1. low inlet flow. 2. The power of drive is
bigger than that of
pump, Water pressure
below 0.5bar. 3. U1-01 value is set
too big.
1. Increase inlet
flow. 2. Modify U1-00
value to be 2. 3. Modify U1-01
value to a small
number. A-02 High water pressure protection
1. Actual pressure
exceeds 15bar
2. Transducer
malfunction,the
readout exceeds
15bar.
1. Modify U1-06
value to a
bigger number. 2. Replace the
failed
transducer . A-03 Low water pressure protection
1. Pressure below
0.5bar under the
normal running
status. 2. Pressure below
0.5bar ,the pump
rotates reversely. 3. Water consumption
is bigger than outlet
flow. 4. U1-08 value is set
too high.
1. Eliminate the air
in the pump. 2. Adjust the
rotation
direction. 3. Increase the
inlet flow
4. Replace with
bigger size
pump or reduce
water
consumption. 5. Change the U1- 08 value to a
small number. A-04 Low current protection
1. Incoming water
shortage. 2. The power of drive is
bigger than that of
pump. 3. U1-04 Value is set
too high
1. Increase
incoming water
2. U1-00 value is
modified as 2. 3. U1-04 value is
modified as a
small number. Fault Information And Trouble Shooting
Fault Code Fault Type Possible Reasons Solutions
E-01 Output Short circuit
1. Output short circuit or
connected to ground
2. Too heavy overload
1. Wiring inspection
2. Ask manufacturer for
help
E-02 Over current in speed
acceleration
1. Acceleration time is too
short. 2. Torque boost is too high
or V/F curve is not
applicable
1. Increase acceleration
time
2. Lower torque
boost,Increase voltage
to adjust V/F curve. E-03 Over current in speed
deceleration
Deceleration time is too short Increase deceleration time
E-04 Over current in running
Abrupt load change Reduce the fluctuation of
load
E-05 Software over current The same as E-01,E-02,E-03 The same as E-01,E-02,E- 03

has aging problems. E-08 Over voltage in speed
acceleration
1. Too high input voltage
2. Frequently switch on and
off
Inspect the power and
voltage
E-09 Over voltage in speed
deceleration
1. Deacceleration time is
too short. 2. Abnormal input voltage
1. Increase deceleration
time
2. Inspect the power
voltage
3. Use new brake resistor
