J1 - IN-OUT
This connector carries all the input and output signals for re-
mote control the TV 81 Navigator.
It is a 15-pin D type connector; the available signals are de-
tailed in the table, the following paragraphs describe the signal
characteristics and use.

Signal description
START/STOP: input signal to start or stop the pump. With the
supplied cover connector, the START/STOP (+) signal is con-
nected to the +24 Vdc pin and the START/STOP (-) signal to
the GROUND pin: in this condition, the pump starts automati-
cally 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 cover connector, the INTERLOCK (+) signal is con-
nected 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:
•
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).
