4.2 View of bypass jumpers

The bypass jumpers bypass the electronics, directly activating the pump control contactors without any

regulating control.

They are used in an emergency, when the electronic board is out of use and it is necessary to ensure

pump operation.

OPEN position = The pump contactors are deactivated.

CLOSE position = The pump contactors are permanently activated and no regulating control is carried

out (to be used only in emergency situations).

SOFTWARE position = pump contactors controlled by the electronic board.

The default position of the jumpers is SOFTWARE.
