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 confirm 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, in
this condition the pump automatically starts as soon as the controller
recognises the input supply ("Plug & Pump"). These pins must be
always connected to +24V and ground to allow pump running.
SPEED SETTING: PWM input signal to set the pump speed. The
PWM signal characteristics must be the following:
