Signal description
START/STOP: input signal to start or stop the pump. With the
supplied mating 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 starts automatically as soon as the
controller recognises the input supply if the interlock is closed ("Plug
& Pump").
INTERLOCK: input signal to control pump rotation. With the
supplied mating 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 "soft start" the pump; in this
condition, the ramp-up time could be up to 20 min.
SPEED SETTING: PWM input signal to set pump speed. PWM signal
characteristics must be as follows:
TwisTorr 84 FS AG Navigator Controller User Manual / 87-901-038-01 (A)
frequency: 100 Hz +/-20 %
amplitude: 24 V max
duty cycle range: from 25 % to 75 %
corresponding to a pump speed between 1100Hz and 1350Hz
(see the diagram below).
