The soft starter manufacturer points out that there are four main reasons for the phenomenon of air jump switch when starting the soft starter:
1. In the starting process, due to the large fluctuation of grid voltage, it is easy to cause the soft starter to send out wrong instructions and bypass in advance. (Users are advised not to start high-power motors at the same time.)
2. Start at full load when starting. (Try to reduce the load when starting)
3. The setting value of air switch with long delay is too small or the selection of air switch does not match the motor. (Enlarge the parameters of the air switch properly or re-select the air switch)
4. The starting voltage parameter of soft starter is set too high or the starting time is too long. (Adjust the starting voltage down or shorten the starting time according to the load)
