Signal Description
Start/Stop: input signal to start or stop the pump. With the supplied cover
connector the START/STOP (+) signal is connected to the +24 Vdc pin and the
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").
Interlock: input signal to control the pump rotation. With the supplied cover
connector the interlock (+) signal is connected to the +24 Vdc pin and the
interlock (-) signal to the GROUND pin.
Speed setting: PWM input signal to set the pump speed. The PWM signal
characteristics must be the following:
