Signal description
START/STOP: input signal to start or stop the
pump. Without the supplied cover connector, if you
want to stop the turbo-pump from outside, you
have to connect the START/STOP (+) signal to the
+24 Vdc pin and the START/STOP (-) signal to the
GROUND pin (this is the default configuration of
the cover connector).
INTERLOCK: input signal to control the pump ro-
tation. With the supplied cover connector the IN-
TERLOCK (+) signal is connected to the +24 Vdc
pin and the INTERLOCK (-)signal to the GROUND
pin: in this condition the pump is stopped.
