The motor needs a minimum torque to start off; however, it draws a high current from the source for this purpose. The high in-rush current is a huge risk to the motor. It can affect its wiring, cause overheating, and decrease its efficiency. Using a hyper-engineering soft starter is one of the best solutions.

A soft starter is a device that reduces the high in-rush current by gently ramping up the motor to full speed. These starters are designed to provide a smooth start to the motor by reducing the impact of high in-rush current.

What model do you need?

When you are trying to determine the appropriate sure start model, you need to consider the type of compressor first. The RLA and LRA of the compressor are listed on the label of every AC unit or heat pump. If the RLA is between 8 to 15 amps, you can use the SS1B08-16SN model. If the RLA is between 16 to 32 amps, you can use the SS1B16-32SN model. If the RLA is between 15 to 16 amps, you need to verify the LRA value; if that value lies below 90, you can use SS1B08-16SN; however, if LRA is above 90, you would use the SS1B16-32SN model.

How to use hyper engineering soft start?

The important thing to remember in installing a soft starter is the direction of installation. You need to install the soft starter in a vertical direction and make sure to leave some space around the starter. If the soft starter is installed in the box, please note that the ventilation is good; you can dig two holes in the box for proper ventilation.

It is good to install a soft starter in a vibration-free environment and away from heat radiation sources. For the same reason, soft starters are not installed directly under the sunlight. There shouldn't be any conductive material near the soft starter. Installation of hyper engineering products should be performed by only a trained individual in Chicago, Il.

How to ensure that soft start is working correctly?

If there is an error in the installation of sure start, the LED light blinks; in such case, you must turn off the system instantly and request technical support to correct the wiring. If there is no blinking, use a FLUKE clamp meter to measure the inrush current. It may take 6-7 starts to fully optimize the starting current.

What if the soft starter stops working?

The soft starter may stop working when there is a voltage hike or too many starts per hour. Sometimes, SCR fails to operate due to an imbalance in voltage and current. Soft starters generate a warning if there is any fault in it. You can instantly switch off the starter and call your technician for help. If there is a problem with the wiring, it can be fixed instantly. In case the starter fails to operate, check the warranty period and contact the buyer for an exchange.
