Fault Description
Both Platform and Ground modes are
selected simultaneously.
Both Footswitches are closed for more then
one second.
Both Steer Left and Steer Right inputs are
closed simultaneously.
The Footswitch was closed for more then
seven seconds.
A drive function was selected with Foot-
switch open.
A steer function was selected with Foot-
switch open.
The D/S Joystick reference volt- age is low.
The D/S Joystick reference volt- age is >
8.1V.
The D/S Joystick center tap volt- age is <
3.08V or > 3.83V.
The L/S Joystick reference volt- age is low.
The L/S Joystick reference volt- age is >
8.1V.
The L/S Joystick center tap volt- age is <
3.08V or > 3.83V.
A lift / swing function was selected with
Footswitch open.
The Footswitch was closed during Platform
selection.
A boom function was selected with Foot-
switch open.
The Footswitch was closed during engine
start.
Pressure transducer sensor voltage output
< 0.4V for 240ms
Pressure transducer sensor voltage output
> 4.5V for 240ms
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
At the end of a lift up event if pressure is
greater than 2200 psi for 3seconds

- Can be reported during power- up.
- Can be reported during power- up.
- Resistive joysticks, these faults do not occur.
- Resistive joysticks.
- If the reference voltage is > 7.7V then the reference
voltage is out of tolerance of a short to battery has
occurred.
- Resistive joysticks.
- There is a +/- .1V range. around these values due to
resistor tolerances
