7. Test Run and Application
Please do some examinations before test running as following:
Whether the rated power of soft starter is matched with the Motor.
Whether the insulation of motor meets requirement.
Whether the main circuit connection of input and output is correct.
Whether all the screws of terminals are twisted tightly.
7.1 Power on to test running
After Power on, please do not disassemble the soft starter cover that is dangerous!
Power on, soft starter displays "READY", and the Ready is light, then you can press "RUN" key to start.
Set
FP
be same as motor nameplate rated current.
After started the motor, you should examine whether the motor running direction is correct, or whether runs
normally. If not, you can press "STOP" key or cut off the power to stop running.
If the soft starter starting state is not satisfied. Please see the detailed explanation at 7.2: the starting mode and
application
If the start torque is not enough, you can change the starting voltage (when the starting mode is voltage control)
or the certain current value (when the mode is current control) to improve start torque.
Do not open the face cover in case of electric shock.
If there is any abnormal voice, smoke or taste, please cut off power as soon as fast, and check the reason.
When the starter power on or be in starting, the error lamp is lighting and screen displays "Err??", at this time,
you can check diagram 7.1 to find out reason .
Press "STOP" key or external stop button can reset the error state.
Note
: When ambient temperature is less than -10
℃
, the starter should be power on to preheat for 30 minute, and
then to start.
Error
Code
Explanation
Reason and the solution way
Error 0
The fault is removed
Any faults are removed, such as low-voltage, over-voltage, over-heat. Now
the Ready-lamp is lighting and you can start the motor.
Error 1
The external
instantaneous stop
terminal is open
Please connect the external instantaneous stop terminal (terminal
⑦
) with
the public terminal (terminal
⑩
).
Error 2
The soft starter is over
heat
The starter is started too frequently, or the starter power is not matched with
the motor.
Error 3
The starting time is over
long, which is longer
than 60s.
The starting parameter is set wrong, or the load is over and the power capacity
is not enough.
Error 4
Input phase failure
Please check whether the input circuit connections, bypass contactor and the
controlled silicon is open or whether the thyristor wire is not connected..
Error 5
Output phase-failure
Please check whether the output circuit connection, bypass contactor and the
controlled silicon are short circuit, or whether the thyristor wire is connected
well.
Error 6
Three-phase unbalance Please check the input three-phase power or the motor is abnormal.
Error 7
Starting over current
Overload, or the motor is not matched with the soft starter.
