Tips: The causes of soft starter SCR damage
1. When the motor starting, the overcurrent will breakdown the soft starter. It is recommended to check whether the power of soft starter matches the power of the motor and whether the motor is on-load starting.
2. The soft starter's cooling fan is damaged. It is recommended to replace the fan.
3. Start up frequently, and high temperature will damage SCR. It is recommended to control the number of times of starting.
4. The filter board is damaged, input default phase, it is recommended to replace the damaged components. There are many factors that cause this failure:

Check whether the power incoming line and the motor incoming line are loose.
Whether the output is connected with load, whether the load matches the motor.
Using a multimeter to check whether the module or SCR of the soft starter is breakdown, and whether the trigger gate resistance meets the normal requirements (typically around 20-30 ohms).
Whether the internal socket wiring is loose.

Soft Starter Works with a Bypass Contactor

Soft starter works with a bypass contactor saving energy by eliminating thyristor losses during the run. The bypass contactor shunts the current flowing through the soft starter switch circuit to reduce heat accumulation in the soft starter power electronics during motor operation. This provides maximum efficiency and prolongs the life of soft-start switching components because they only work during the start and stop cycles of the motor.

Soft Starter Bypass Output Failure: How to Continue Motor Operation

In this video, you are shown how to use an AC contactor in conjunction with a soft starter as a backup solution to start a motor when the soft starter's bypass output is not operational. The strategic combination of a soft starter and an external bypass contactor provides a fail-safe mechanism for motor starting and operation, especially when faced with challenges with the soft starter bypass output.

Delayed Soft Start of A Motor

In this video, we introduce how to use a soft starter together with a bypass contactor to achieve a delayed soft start of a motor.

The perfect 60hp soft starter

60hp soft starter works very well for starting my work tools. It seems like an excellent product for the way I use it. I often use it to start the motor and pump.
