TRIGGER CLOSED TOO
LONG WHILE IN NEU-
TRAL
The trigger switch was closed for
more than five seconds while
the joystick was centered.
•
Check if the trigger switch is obstructed or jammed.
•
Check the trigger switch signal and wiring to the platform board. The trig-
ger input (24V) is from platform board terminal J1-1, and its output (24V
when closed) is to platform board terminal J1-8.
•
Replace platform board.

FUNCTION PROBLEM - DRIVE &
LIFT BOTH OPEN
The drive and lift inputs are both de-ener-
gized in Platform Mode.
•
Check if either function is active, if Yes;
•
Repair the wiring or switch to clear the message.

231
FUNCTION PROBLEM -
LIFT PERMANENTLY
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. The lift switch
input (24V) is from ground board terminal J2-4, and its outputs (24V
when closed) are to ground board terminals J2-6, J2-7 (up and down).
•
Replace ground board.
232
GROUND LIFT UP /
DOWN ACTIVE
TOGETHER
The lift up / down inputs are
closed simultaneously.
•
Check if the lift switch is obstructed or jammed.
•
Check the lift switch signal and wiring to the ground board. The lift switch
input (24V) is from ground board terminal J2-4, and its outputs (24V
when closed) are to ground board terminals J2-6 (up), J2-7 (down).
•
Replace ground board.
233
FUNCTION PROBLEM -
BRAKE RELEASE PERMA-
NENTLY SELECTED
The manual brake release switch
was closed during power-up.
•
Check if the brake release switch is obstructed or jammed.
•
Check the brake release switch signal and wiring to the ground board. The
brake release switch input (24V) is from ground board terminal J1-19,
and its output (24V when closed) is to ground board terminal J1-20.
•
If the brakes are released, the machine can be pushed or moved without
drive motor power.
•
Replace ground board.

ELEV ANGLE SENSOR
FAULTY - VOLTAGE OUT
OF RANGE
The elevation angle sensor
input voltage is outside the
acceptable range of 0.10V -
4.50V.
•
Check that the platform elevation sensor is securely mounted and
undamaged.
•
Check voltage as displayed on ANALYZER -> DIAGNOSTICS -> ELEV SEN-
SOR -> ANGLE SNSR. Backprobe ground board J1-15. If this voltage dis-
agrees with the ANGLE SNSR voltage, replace the ground board.
•
Backprobe the elevation angle sensor connector. Terminal A should be
4.7V, terminal C should be 0V.
•
Check the elevation angle sensor signal and wiring to the ground board.
The elevation angle sensor input is from ground board terminal J1-14
(4.7V), its output (0.1 - 1.2V when stowed) is to ground board terminal
J1-15, and its ground is to ground board terminal J1-16.
•
Replace the ground board.
252
ELEV ANGLE SENSOR
HAS NOT BEEN CALI-
BRATED
The elevation angle sensor has
not been calibrated.
•
Calibrate the elevation angle sensor to clear fault. See Section 5.5.
