Possible Causes
|
Suggested solution
|
|
01
|
Input
phase
loss
|
1. The start command is
issued, and one or more phases of the soft start are not energized. 2. The main board of the circuit board is faulty. |
1. Check whether the main
circuit has electricity 2. Check whether the SCR of the input circuit is open, and whether the pulse signal line is in poor contact. 3. Seek help from the manufacturer. |
|
02
|
Output
phase
loss
|
1. Whether the SCR is
short-circuited. 2. One or more phases of the motor wire are open. 3. The main board of the circuit board is faulty. |
1. Check whether the SCR
is short-circuited. 2. Check whether the motor wire is open. 3. Seek help from the manufacturer. |
|
03
|
Running
overload
|
1. The load is too heavy.
2. Improper parameter settings. |
1. Replace the soft starter
with more power. 2. Adjust the parameters. |
|
04
|
Underload
|
1. The load is too small.
2. Improper parameter settings. |
1. Adjust the parameters.
|
|
05
|
Soft
overheating
|
1. The temperature switch
is faulty. 2. The fan does not rotate. 3. The working time of soft start is too long. |
1. Check whether the
temperature switch is faulty. 2. Check whether the fan is working normally. 3. Stop the machine and let the soft start cool down. |
|
06
|
Over
-pressure
|
1. The input power supply
voltage is too high. 2. Improper parameter settings |
1. Check the power supply
voltage. 2. Adjust the parameters. |
|
07
|
Under
-voltage
|
1. The input power supply
voltage is too low. 2. Improper parameter settings. |
1. Check the power supply
voltage. 2. Adjust the parameters. |
|
08
|
Running
overcurrent
|
1. The load is too heavy.
2. Improper parameter settings. |
1. Replace the soft starter
with more power. 2. Adjust the parameters. |
|
09
|
Starting
overcurrent
|
1. The load is too heavy.
2. Improper parameter settings |
1. Replace the soft starter
with more power. 2. Adjust the parameters. |
|
10
|
External
fault
|
1. The external fault
terminal has input. |
1. Check whether there is
input at the external termina |
|
11
|
Phase
sequence
failure
|
1. The input power phase
sequence is inconsistent with the setting. |
1. Adjust the power phase
sequence. 2. Adjust the parameters. |
