Pump alternating relays

This device, thanks to the use of a pressure switch inserted in the circuit, permits the control and inversion of the 2 pumps in the autoclave systems.
The system depends on the state of a float, which prevents its function in the absence of water.
It is possible to insert a second pressure switch (or emergency pressure switch) that allows for both pumps to operate when one is insufficient to maintain the pressure of the system in the required supply conditions.
Furthermore, in the event of a faulty pump the circuit recognizes the state and permits the activation of the other one thereby always allowing for water delivery.
Thanks to this device, it is possible to realize the control of the conventional autoclave system, with the sole addition of the contactor and the thermal part, at greatly reduced costs.

This device allows to make a control panel for autoclave by only adding contactors and thermic relays.
It consists of a base unit suitable for din guide and of a panel containing two switches for pump operation and seven led diodes that always show the autoclave status.
