FAQs

The bypass of the soft starter cannot be closed

The user finishes using the soft starter but the bypass contactor does not pull closed. The causes may be as follows: (1) In the starting process, an error action is caused due to the relatively low value setting of the protection device. ( Just re-adjust the protective device) (2) In the debugging, the parameters of the soft starter are improperly set. (3) The control line is in bad connection. (Check the control circuit) (4) The control panel of the soft starter fails. (Contact with the factory of the soft starter)

The non-full-phase fault of the soft starter

In the debugging process of the soft starter, there reports a non-full-phase fault, with failure indicator lighted but the motor no responding. The cause of the malfunction may be as follows: (1) The soft starter intrigues protection action due to the non-full-phase fault of the power supply.(check the power supply) (2) No load is connected to the output terminal of the soft starter (The soft starter will not work properly until the output terminal is connected to a load. ) (3) F2 should be set to 0 using multiple control mode. (4) The internal controllable silicon trigger line of the soft starter is in bad connection or the control board is in fault. (Contact with manufacturer)

The switch jumps off when the soft starter starts

The switch jumps off occasionally during the start. The reasons can be as follows: (1) The setting value of the long time delay of the air switch is too small or the model of the air doesn’t match the motor. (Enlarge the parameter of the air switch or choose new type of air switch). (2) The starting voltage parameter of the soft starter is too high or the starting time is too long. (Lower the starting voltage properly or shorten the starting time. ) (3) The soft starter tends to issue wrong instructions and induce early bypass due to the relatively big fluctuation of the power grid voltage in the start process. (It is suggested that users do not start high power motors at the same time.) (4) Full load start (Try to reduce load when starting. )
