Reason
1. Abnormal sensor
2. The parameter B01.00
setting value is too small
3. Water level is too low
4. Abnormal water level
switch
5. Wrong setting of water
level switch style parameter
1. Pressure transmitter
disconnected
2 . W r o n g p r e s s u r e
transmitter wiring
3. Pressure transmitter
short circuit
4. Pressure transmitter
breakdown
1. Acc/Dec time is too short
2. IGBT module fault
3. Malfunction caused by
interference
4. Grounding not properly
done
1. Acc time is too short
2. Low input voltage
3. Low power of controller
1. Dec time is too short
2. Load is too big
3. Controller undersized
1. Sudden change of load
2. Low input voltage
3. The power of controller
is small

Solution
•
Check the installation of pressure
transmitter
•
Check the parameter b01.00 (setting
value is too small)
•
Check the water system
•
Check the condition of the control
terminal S3
•
Check the parameter
correct
•
Check the cable between pressure
transmitter and controller
•
Check the sensor whether normal
•
Increase Acc/Dec time
•
Check external equipment and
eliminate interference
•
Check earth wiring
•
Contact Dayliff retailer
•
Prolong Acc time
•
Check the power supply
•
Select bigger power controller
•
Prolong Dec time
•
Increase braking time
•
Select bigger power controller
•
Check the load
•
Check the power supply
•
Select bigger capacity controller
