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.
Soft start: this input is used to provide a "soft start" to the pump; in
this condition the ramp-up time could be up to 45 min.
