7 PRESSURE SENSING

The System measures the pressure of the boom lift cylinder for both rod- and piston-side. Both
sensors are contained within one box that also contains the electronics needed for amplification and
creation of the CAN-Bus signal.

Block Diagram:

The signal runs from the pressure transducer as
digital information on the CAN-Bus to the central
unit.

Pressure Sensing Error

First, verify the pressure displayed through the

console by using the sensor output screen.

Press the info
button twice

Pressure transducers are

functioning correctly.

Does the

displayed value

differ from the

actual value?

The readout should

read 500mV (+/-

25mV) and 0 PSI.

If the reading is slightly off, small variations can be adjusted;
see section Service Screen For Sensor Calibration.

Ensure that the pressure lines

are drained and disconnected.

Replace pressure transducers.

YES
