FUNCTION ENABLE
INTERLOCK –
ENABLE SWITCH
NOT SELECTED
FIRST 2227 1 The requested function will be
ignored.
If the PLATFORM STATION is
active and a platform is configured
as ENABLED and a platform is
detected as attached and a
hydraulic function request is detect
at the platform station before the
function enable signal was
received.
The hydraulic
function
request is no
longer active.
FUNCTION ENABLE
INTERLOCK – NOT
SELECTED IN TIME 2228 1 Turn OFF the functions enabled
indicator at the platform station.
Ignore all function requests from
the platform station while the
FUNCTIONS ENABLED state is
active.
If the PLATFORM STATION is
active and a platform is configured
as ENABLED and a platform is
detected as attached and if a
function request is not received
within the 7 second period from the
time the FUNCTION ENABLE state
is activated.
The function
enable switch
is released.
ENGINE START
PREVENTED –
FUNCTION ENABLE
SWITCH ENGAGED 2229 1 The engine start signal will be
ignored. J2-26 Engage Starter will
be deactivated and inhibited.
When the PLATFORM STATION is
active and the engine start signal is
detected at the platform and the
UGM detects the function enable
switch is engaged.
The function
enable switch
is released.
PLATFORM
JOYSTICK – OUT
OF RANGE HIGH 2230 1 Hydraulic functions
(Lift and Telescope) associated to
the dual-axis platform joystick are
inhibited.
The platform module detects the
input voltage for dual-axis joystick is
out of range on the high side and
reports the issue to the UGM.
Power cycle.
PLATFORM
JOYSTICK –
CENTER TAP BAD 2231 1 Hydraulic functions
(Lift and Telescope) associated to
the dual-axis platform joystick are
inhibited.
The platform module detects center
tap dual-axis joystick voltage is out
of range and reports the issue to
the UGM.
Power cycle.
FUNCTION ENABLE
RELAY – INVALID
SIGNAL 2233 1 Deactivate and inhibit platform
module output J2-19 Function
Enable Relay.
Deactivate and inhibit UGM output
J2-26 Engage Starter.
Suppress the “FUNCTION

Signal does not change states from
HIGH to LOW during the power-up
test sequence.

OPERATING MODE
INTERLOCK –
SHIFTER NOT IN
NEUTRAL 239 1 J2-26 Engage Starter output will be
deactivated and engine start will
not be permitted if the PLATFORM
STATION is active and CABIN
MODE was the last valid operating
mode.
Changeover to PLATFORM MODE
will not be permitted.
The PLATFORM STATION is active
and CABIN MODE was the last
valid operating mode and a platform
is detected as attached and the
drive direction inputs are not
detected as follows: (J4-4 Neutral-
HIGH, J7-22 Forward-LOW, J4-18
LOW).
A valid drive
direction of
Neutral exists
(J4-4 is the
only HIGH
shifter input).
