The Deragger II® is simple to integrate into existing starter sections. In this entry we will be demonstrating the integration of the Deragger II® into DOL starters. This will demonstrate how you can get anti ragging the easy way. Our slimline device (35mm) is perfect when space is not a premium and with its patented clean technology, is the perfect solution for this type of problem.
The device takes a run signal to start. This is taken from the A1-A2 coil of the existing line contactor. Remove the wires from the existing contactor and put them in the common and Input 1 on the Deragger II®. A volt free contact from the reset push button is wired into Input 3.
The Deragger II®’s patented anti ragging technology relies on a reversing contactor to assist with the cleaning operation of three phase pumps. This should, ideally be mounted next to the existing line contactor. We recommend Schneider contactors due to the slim profile.
The contactors are connected as shown below remembering to feed the cables through the power module:
Next the overload is removed and the existing fault wires (N/O, N/C) are wire into output 3 and 4 of the Deragger II®. This is how to interface the unit with the panel’s trip circuitry and any telemetry that may be present.
The unit is now installed and ready to commission.
