Siemens Soft Starter 3RW44 can self-reset can be fault

Not all faults can be self-reset. The faults that can be self-reset are as follows (The method of self-reset is to set the corresponding parameters in the menu of the LCD screen) :

1) Motor thermal model overload. The method to achieve self-reset is to select "Settings" -> "Response..." -> "Hot load Motor Model - Overload" -> "Trip Restart"

2) Power element overheating. The method to achieve self-reset is to select "Settings" -> "Response..." -> Thyristor Overload -> Trip Restart

3) The temperature sensor is overloaded. The method to achieve self-reset is to select "Settings" -> "Response..." -> Temperature Sensor-Overload -> Trip Restart

4) The temperature sensor is short-circuited. The method to achieve self-reset is to select "Settings" -> "Response..." -> Temperature Sensor-Overload -> Trip Restart

5) The temperature sensor wire is broken. The method to achieve self-reset is to select "Settings" -> "Response..." -> Temperature Sensor-Overload -> Trip Restart

6)PIO error. No parameters to set

After the parameters are set, the soft starter can reset itself when the fault is removed automatically or manually.
