This device is intended to control the functionality of two water pumps. Two main boards, The Control Board and The Power Board achieve the “The Automatic Pump Controller”.
The Controller Board performs several operation modes of water pumps: the manual mode, automatic mode for one pump or automatic mode for two pumps.
The protection of pumps against supercharges and missing of water is also provided. This control board is build around a “PIC16C84” processor and all the inputs and outputs to the system environment are optically isolated in order to have protection against the strong perturbation and noises specific of this application.
The Power Board contains all necessary components to connect and drive the pumps motors; the execution elements (opto-triacs 16A) to drive two electrical motors (740watts, three phases), the supply sources, power connectors and fuses.
