Section VIII Fault causes and treatment
Fault codes and treatment as following table：
Problems and treatment methods
Just happened undervoltage, overvoltage or
overheating, instantaneous stop terminals are open,
such failures, now has been normal, this time to
prepare lights, reset to start the motor.
External terminal
momentary
open circuit
Short-circuit connection with the external
Instantaneous stop terminal⑦and public terminal⑩,
or connecting to other protective devices normally
closed contact.
Start too often or the motor power do not match
with the soft starter.
Starting times
too longer than
60 seconds
Starting parameter settings is inadequate or the load is
too heavy, the power capacity is not enough, etc.
Check the input or main circuit failure, whether the
bypass contactor is stuck in the closed position and
whether the SCR is in open circuit and so on.
Check the input or main circuit failure, whether the
bypass contactor is stuck in the closed position and
whether the SCR is in open circuit and so on.
Check whther the input three-phase power supply
and the load motor is normal.
Whether the load is too heavy or motor power does
not match with soft starter.
Running overload
protection
Whether the load is too heavy or setting items P6,
PP parameters set incorrectly.
Supply voltage is
too low
Check the input voltage or setting item P7
parameter set incorrectly.
Supply voltage is
too high
Check the input voltage or setting item P8
parameter set incorrectly.
Modify the settings, or pressing the Enter key on
power to restore the factory values.
Check whether overloading or thyristor short circuit.
Automatic re-start
wiring error
Check whether the outside the control start and stop
terminal is connected to 2-wire mode.
External stop
terminal wiring
error
When you allow external control mode, the external
control stop terminal is in the open state, which can
not start the motor.
Check the motor shaft and load faults.
