Pump control unit located in the power cord and compatible with multiple pump units
First Claim
1. A system for controlling a pump, comprising a pump and a control unit connected to the pump by a three phase electrical power supply cable, wherein:
- the control unit is, irrespective of a power rating of the pump, detachably connectable to the pump via the electrical power supply cable,the control unit is compatible with pumps having different power ratings,an electronic controller is arranged in the pump, the electronic controller including a soft starter unit for starting the pump and a microcontroller unit for monitoring at least one of the pump'"'"'s operating conditions,the pump and the control unit are adapted to communicate with each other and transmit data/signals over the electrical power supply cable, comprising control and/or monitoring information/data for managing the system,the pump and the control unit pair automatically such that the control unit receives signals or transmits signals adapted to a specific power rating of the pump paired to the control unit,the control unit is connected to the electronic controller of the pump and located along the electrical power supply cable between a power supply and the pump, andthe pump is maintained operational by the electronic controller arranged in the pump when the control unit is bypassed.

Abstract
Disclosed is a system for controlling a pump, such as a submersible pump intended for pumping water, including a pump and a separate electronic control unit connected to the pump by an electrical cable. The control unit is adapted to be detachably connected to the pump. The control unit is adapted to allow the pump'"'"'s power supply to pass through the control unit. An electronic controller is arranged in the pump for controlling at least one of the pump'"'"'s functions and/or monitoring at least one of the pump'"'"'s operating conditions. The pump and the control unit are adapted to communicate with each other and transmitting signals, including necessary control and/or monitoring information/data, between each other.
