15KW Soft Starters Details

Tips: Soft starter protection functions
Soft starter has overload protection, open-phase protection, overheating protection, measurement loop parameters and other functions.

Overload protection: Soft starter introduces a current control loop, so it can trace and detect motor current changes at any time. By increasing the overload current setting and inverse time control mode, it can achieve the overload protection function. When the motor overload, it will turns off the thyristor and send an alarm signal.
Open-phase protection: While working, the soft starter detects changes in three-phase line current at any time, once the break occurs, it will make a reaction of open-phase protection.
Overheat protection: Through the soft starter internal thermal relay to detect the temperature of the thyristor radiator, once the radiator temperature exceeds the allowable value, the soft starter will automatically turns off the thyristor and send an alarm signal.
Measuring loop parameters function: When the motor is working, the detector in the soft starter monitors the running state of the motor all the time, and sends the monitored parameters to the CPU for processing. The CPU will analyze, store and display the monitoring parameters. So the motor soft starter also has the function of measuring loop parameters.
Other functions: Through the combination of electronic circuits, the soft starter can also achieve various interlock protection in the system.

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.

Durable soft starter

We've had this soft starter for almost three years now. Sometimes it pops up "output lost" error and unable to stop the motor. Or motor stops without pressing stop. We did check that. All wires and connections are firm and intact. I wonder if the problem is be in the control pad in cover. Still, I'm happy with it after three years of use and plan to go back for a new one.

1. Regarding this unit getting "output lost" error, can you provide us with photos or a video for confirmation? You can also press the YES button through the operation panel, and then scroll up and down to find the fault record information at the back. And please provide us with photos of the fault information. You can send us the large video file via wetransfer.com.
2. You can replace the control board with a new one, but you need to provide us with a picture of the nameplate label of the soft starter to confirm the specific model.

A question about soft starter

I bought a soft start last month. If possible, hook up a time delay timer to be able to turn off the motor and motor starter with your soft starter. How can I install a timer to turn off my machine's motor without completely shutting off the power to the starter and instead let the soft starter turn off the motor after the desired run time.

Our suggestion is that you can use a timer to control the start/stop signal of the soft starter. When the time counted by the timer is up, the stop signal of the soft starter will be triggered, and the soft starter will stop running, thereby stopping the motor.

Soft starter don't release power to the by pass contactor

I just hook up a.control panel. For a 20 hp pump with a soft starter. And the pump start to working but 30 seconds ..stop..I noticed the soft starter don't release power to the by pass contactor. Can you help me? Please.

You could first check whether the wiring of the soft starter is normal, please refer to the following video to check the wiring, including setting parameters, see on: https://www.youtube.com/watch?v=GkSo1DOBHlM
If the problem persists, please provide us a video for reference, which should include showing how your soft starter is wired.

Good 20 hp soft starter

Great! The motor starts smoothly, the noise of starter is very small, safe and secure.
