What fault does ABB soft starter show EF32?

What is ABB soft starter fault codes EF32.

The ABB PSE series soft start is a three-phase controller with a compact design and a wide range of applications.It is mostly used in water pump motors,and the faults that occur are often failure to display the start and no response,alarm when starting,self stop during operation,and failure to close the bypass.

Repair strategy:The soft start fault alarm can generally be resolved by referring to the instruction manual.If the fault caused by external factors is eliminated and there is still a fault,it can only be sent for repair.EF generally refers to external faults,but the periphery is normal,and only the control part and host can be checked.EF32 is undercurrent,one or more phases undercurrent.

(1) Check whether the wiring between the incoming power supply and the motor is loose;

(2) Whether the output is connected to the load, and whether the load matches the motor;

(3) Use a multimeter to detect whether there is a breakdown in the module or thyristor of the soft starter, and whether their trigger gate resistance meets the requirements under normal conditions (generally about 20-30 euros);

(4) Whether the internal wiring socket is loose.
