Overheating occurs during starting, light is on, and soft starter stops working:
Frequent starting, resulting in excessive temperature, resulting in overheating protection action of soft starter. (soft starter starting times should be controlled at less than 6 hours per hour, especially heavy load must pay attention)
In the starting process, the protection element moves, so that the contactor can not bypass, soft starter work for a long time, resulting in protective action. (check peripheral circuit)
Overload starting time is too long to overheat protection. (starting, as much as possible to reduce the load)
(4) the parameter setting of soft starter is unreasonable. Too long, too low starting voltage. (raise the starting voltage)
The cooling fan of the soft starter is damaged and can not work properly. (replacing fan)
