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:
frequency: 100 Hz +/-20 %
amplitude: 0 - 24 V max
duty cycle range: from 25 % to 75
%
corresponding to a pump speed from 272 Hz (25 %) to 714 Hz
(75 %) linearly.
