Location:

See Pressure Sensor Location on page 35.

The pressure sensor is an electronic oscillator that
changes its output frequency according to the air
pressure present on its diaphragm. Air pressure
is delivered to the pressure sensor through the
pressure sensor hose which also connects to the air
dome. The air dome is designed to build air pressure
as water

fi

lls the tub.

Pressure sensor frequency can be read between
pins 1 and 2 of the pressure sensor. The pressure
sensor requires a 5 VDC between pin 2 (brown) and
pin 3 (tan) to operate. The output is taken between
pin 1 (brown) and pin 2 (grey).
