Signal Description
Start/Stop : input signal to start or stop the pump. With the supplied cover

START/STOP (-) signal to the GROUND pin: in this condition the pump
automatically starts as soon as the controller recognises the input supply
("Plug & Pump").

connector the interlock (+) signal is connected to the +24 Vdc pin and the
interlock (-) signal to the GROUND pin.
