2 2 T RIGGER CLOS ED TOO LONG WHI LE IN NEU-
TRAL
Trigger switch in the platform control box was closed for
more than ten seconds while the joystick (accelerator) was
in the neutral position (centered).
In Platform Mode, the Trigger Digital Input was Energized
for 10,000mS AND
Drive was In-Active AND Lift was In-
Active. Retained until the Trigger Digital Input is momen-
tarily De-energized.
Drive, Steer, & Lift Prevented.
Release switch or repair the
switch / wiring to clear the diffi-
culty.
Help messages with the 2-3 flash code indicate difficulty with the ground controls.
2 3 FUNCTI ON PROBLEM – LI FT PERMANENTLY
SELECTED
Lift switch (up or down) in the ground control box was
closed during power-up.
In Ground Mode, [Lift Up Digital Input is Energized or Lift
Down Digital Input is Energized] AND
Power-up is Active.
Retained until the respective Digital Input is momentarily
De-energized.
Lift Prevented
Release or repair the switch to
clear the message.
2 3 GROUND LIFT UP/DOWN ACTIVE TOGETHER In ground mode, the control system has detected the lift up
and down are active simultaneously.
In Ground Mode, Ground Lift Up Digital Input is Energized
and Ground Lift Down Digital Input is Energized. Retained
until both the Digital Inputs are momentarily De-energized.
Lift Prevented
Check the lift switch and asso-
ciated wiring in the ground
control box.
2 3 N O DATA FRO M T ILT SENS OR – NOT CON-
NECTED OR FAULTY
No signal from the tilt sensor mounted inside the ground
control box.
Transitions on the Tilt X OR Tilt Y signals not detected for
2000mS. Retained until transitions on both are sensed.
Vehicle assumed Tilted (+20.0’ X, +20.0’ Y); Drive Stowed
Demand limited as in Worst-Case Slope Descent Func-
tionality for both Forward and Reverse
Drive will be slow in the Forward direction.
Check wiring and plug con-
nections at the tilt sensor and
at the ground control board.
2 3 T ILT SENS OR NOT CALIBR ATED T he Til t Sensor ’s Calibratio n EEPROM is set to the sig na-
ture implanted by the In-Circuit Test Fixture. Retained until
Calibration EEPROM is over-written by a valid calibration.
Vehicle assumed Tilted (+20.0’ X, +20.0’ Y); Drive Stowed
Demand limited as in Worst-Case Slope Descent Func-
tionality for both Forward and Reverse
Drive will be slow in the forward direction.
Calibrate the Tilt Sensor using
the calibration procedure to
clear the message.
2 3 FUNCTION PROBLEM -- BRAKE RELEASE PER-
MANENTLY SELECTED
The ground control box lift switch was closed up or down,
during power-up in ground mode.
Check if the lift switch is
obstructed or jammed. Check
the lift switch signal and wiring
to the ground board. Replace
ground board.
