Cautions

Dangers

1. Do not disassemble or modify, otherwise it may cause electric shock, fire, or injury.

2. Do not open the cover during power-on.

3. Do not put wires, thin rods, filaments, and other items into or fall into the controller to avoid short circuit or electric shock hazard.

4. Do not splash water or other liquids.


Warnings

1. Do not perform voltage withstand test on the internal components of the controller;

2. Never connect the power cord to the output terminals U, V, W;

3. If the circuit board components inside the controller are affected or damaged by static electricity, please do not touch them casually;

4. The motor and controller should match the power supply specifications, otherwise it may cause abnormal operation or even burn out the equipment;

5. If there is severe vibration, noise, heat or odor during the initial operation, turn off the power immediately and contact the supplier or service center;

7. Do not expose the product directly to outdoor environments such as sunlight, frost, snow, etc., to avoid deformation or electric shock damage.



Troubleshooting


Fault phenomenon

Cause of failure

Countermeasures

Failed to sleep

1. There is water leakage in the outlet pipe;

2. Poor sealing of the check valve;

3. The pressure tank is damaged;

4. Too much environmental electromagnetic interference;

5. Parameter setting error

•  Check the water outlet pipeline and increase b04.04 appropriately;

•  Check the check valve;

•  Replace the pressure tank;

•  The sensor adopts shielded wire, and the shielding layer is grounded;

•  Confirm parameter b04.00=1


Inaccurate display pressure

1. Sensor/pressure gauge deviation;

2. Improper parameter setting;

3. The pressure feedback line is too long

•  Use standard pressure gauge;

•  Calibration parameters b01.05, b01.08;

•  Avoid using too long pressure signal line


Full frequency operation, no constant pressure control

1. No pressure feedback;

2. The parameter setting is wrong;

3. The water pump is too small

•  Check the pressure sensor and wiring;

•  Check whether b05.02=1 is set incorrectly;

•  Check if there is an external switch to turn on S2-COM;

•  Set b07.14=1 to reset parameters


Pressure turbulence, take long time to be steady

1. The PID value is inappropriate;

2. The acceleration and deceleration time is too short;

3. There is a long delay in pressure feedback

•  Properly adjust the PI values b02.03 and b02.04;

•  Properly adjust the acceleration and deceleration time b05.03, b05.04;

•  Avoid using too long pressure signal line


The motor is noisy

1. The motor is abnormal;

2. The motor installation is not stable;

3. The frequency converter carrier is low

•  Check the motor;

•  Properly increase the inverter carrier frequency b05.08



After-sales service

1. The warranty is limited to the inverter itself. Within 12 months from the date of purchase, the inverter will provide free maintenance services if the product is damaged due to malfunctions caused by the product itself within 12 months from the date of purchase.

2. During the warranty period, if something happens, our company will charge a certain amount of maintenance fee depending on the situation.

A. Failure to strictly follow the "Instruction Manual" or exceed the standard requirements in an environment that does not meet the requirements of the "Instruction Manual".

B. Failure caused by self-repair or modification without permission.

C. Faults caused when the inverter is used for abnormal functions.

D. The inverter is damaged due to incorrect wiring.

E. Damage caused by improper storage, fall or other external factors after purchase.

F. Failures caused by natural disasters such as abnormal voltage, lightning, fire, water mist, metal dust, gas corrosion, earthquakes, storms, or disaster-related causes.

G. Tear off the product identification (such as nameplate, etc.) without authorization; the serial number of the body does not match the warranty card.

3. If you have any questions, please contact the agent or contact our company directly.
