Cautions

1. Environment temperature range: -10℃~+40℃. Controller’s power will be reduced if ambient temperature exceeds 40℃.

2. Prevent rain drops, moist environment, oil fog, salt erosion, corrosive gas, etc..

3. Prevent direct sunlight, keep away from radiation source.

4. Prevent violent vibration or sudden impact.

5. Lower than 1000m installation altitude. The controller’s power will be reduced when the altitude is higher than 1000m.

be careful

• When moving the controller please lift by its base and don’t lift by the panel. Otherwise may cause the main unit fall off which may result in personal injury.

• Install the controller on the fireproofing material (such as metal) to prevent fire.

• When power off, should not install the controller until the power indicator light was extinguished, which can ensure the device has been discharged completely.

• Disconnect all power line before opening front cover of unit. Wait at least 5 minute until DC Bus capacitors discharge.

• Set b07.14=1, take a factory reset

Pressure Vibration,

Stabilize Slow

1. PID value unmatched;

2. Acc. /Dec. time too fast;

3. Big delay on pressure feedback

• Tune PI value b02.03, b02.04;

• Tune Acc./Dec. time b05.03, b05.04;

• Avoid use too long transducer wires


Motor Noise

1. Motor abnormal;

2. Motor installation is not stable;

3. Low carry-frequency

• Check motor;

• Proper turn up carrier frequency b05.08

High Water Pressure and Low Water Level (HP+LL)

1. Abnormal sensor;

2. The parameter b01.00 setting value is too small;

3. Water level of pool is too low;

4. Abnormal water level switch;

5. Wrong setting of water level switch style parameter

l Check the installation of pressure transmitter;

l Check the parameter b01.00 (setting value too small)

l Check the water system

l Check the situation of the control terminal S3

l Check the parameter b05.00

E022

Sensor Fault

1. Pressure transmitter disconnected;

2. Wrong pressure transmitter wiring;

3. Pressure transmitter short circuit;

4. Pressure transmitter break down

l  Check the cable between pressure transmitter and controller;

l Check the sensor whether is normal


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.

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.
