D/S JOY. OUT OF RANGE HIGH
The D/S Joystick reference volt- age is >
8.1V.
- Resistive joysticks.
- If the reference voltage is > 7.7V then the reference
voltage is out of tolerance of a short to battery has
occurred.

D/S JOY. CENTER TAP BAD
The D/S Joystick center tap volt- age is <
3.08V or > 3.83V.
- Resistive joysticks.
- There is a +/- .1V range. around these values due to
resistor tolerances

LIFT PRESSURE SENSOR - OUT OF RANGE
LOW
Pressure transducer sensor voltage output
< 0.4V for 240ms
Check sensor hardware and wiring

LIFT PRESSURE SENSOR - OUT OF RANGE
HIGH
Pressure transducer sensor voltage output
> 4.5V for 240ms
Check sensor hardware and wiring

LIFT PRESSURE SENSOR - NOT DETECTING
CHANGE
Lift down is commanded and pressure does
not change by 20psi within 10seconds. This
is only evaluated when rod-side pressure
starts out below a threshold value
Check sensor hardware and wiring
23127

LIFT CYLINDER - OVER PRESSURE
At the end of a lift up event if pressure is
greater than 2200 psi for 3seconds
Check lift cylinder seal across piston, fault detects a
hardware failure
