If you suspect a sensor error or problem with a sensor, compare the indicated physical value of the
sensor on the display screen with the real value, i.e. length, angle, etc.
The voltages given are internal calculation values only; you will not be able to actually measure them
anywhere on the electronics! Typical values to be expected are:
Pressure transducers (piston and rod), 500mV @ 0 PSI; 4500mV @ maximum PSI
Length sensor, 500mV @ retracted boom length; voltage extended depends on the various
boom lengths.
Angle sensor, 4500mV at 0; 2500mV at 45; or 500mV at 90
Please refer to table below for more values.
Voltage Values
displayed [mV] +/- 10mV
Pressure Transducers
300 bar, type 314
If the displayed value does differ from the actual value, please refer to the following sections to find
the cause of the problem:
If the displayed angle is incorrect, please go to section Angle Sensing.
If the displayed length is incorrect, please go to section Length Sensing
If the displayed pressures are incorrect, please go to section Pressure Sensing
