Error03
Soft starting time is too long
Too low current limit makes the starting time too long (more than 60s)
The starting parameter setting is inappropriate or the load is too heavy, current capacity is
insufficient, etc.
Error04
Input phase loss
Check input or main circuit fault, bypass contactor stuck in closed position and SCR open
circuit
Error05
Output phase loss
Display and description Problems and solutions
Error06
Three-phase imbalance
Check whether the input three-phase power supply and the load motor are normal.
Error07
Starting over-current
Check whether the load is too heavy or the motor power does not match the soft starter
Error08
Over-load
protection of
operation
During starting:
①
Check and correct the reasons of the overload, check whether the current limit multiple
is not too low;
②
Check whether the boost time during starting is not too long;
③
Check
whether the appropriate motor overload category is used;
④
Check whether the
parameter setting current is set correctly.
During the connection and operation:
Check and correct the reasons of over-load
Error09
Too low power voltage
Check whether input power voltage or the parameter setting of setting item F7 is improper
Error10
Too high power voltage
Check whether input power voltage or the parameter setting of setting item F8 is improper
Error11
Setting parameter errors Modify the setting parameters or hold down the[YES] button, power on and restore the
factory settings
Error12
Load short-circuit fault
Check whether the load or SCR is short-circuited or the load is too large
Error13
Thyristor short-circuit fault Check whether the thyristor is short-circuited or the temperature control switch is
damaged
Error14
Stop terminal wiring error When the external connection mode is allowed, the external control stop terminal is in an
open state, so that the motor cannot be started.
Error15
Motor load fault Check the reasons of under-load, and make correction
Check whether the setting is in accordance with the operating condition
Remark:
1. Some fault phenomena are related to each other. For example, when the Error02 soft starter is reported to be
overheated, it may be related to starting over-current or load short-circuit. Therefore, when checking the fault,
comprehensive consideration should be given to accurately determine the fault point.
2. When the soft starter starts the motor successfully, it means it is already running. If it displays "running..." at this time.
When the motor stops running, check that the DIP switch is in bypass mode.
