2315 1, 15 J2-26 Engage Starter output will be
deactivated and engine start will
not be permit ted if the PLA T FORM
STATION is acti ve and CABIN
MODE was the last valid operating
mode.
Changeover to PLATFORM MODE
will not
be permitted. If PLAFORM
MODE is already the valid
operating state and the UGM has
not detected any chassis tilt
condition, then inhibit the Lift
function until the Boom Retracted
switch is HIGH. Once the Boom
Retracted switch i s HIGH, the UGM
will permit the Lift Down
Function to operate and inhibit the
Telescope Out function. Once the
UGM detects the boom angle is
below 10°, the Telescope Out
function will be permitted and the
Lift function permitted up to a boom
angle of 10°. If the UGM detects a
chassis tilt condition with a tilt
sensor angle reading of ABSO-
LUTE TRIP POINT 1 or higher but
less than ABSOLUTE TRIP POINT
2, the above retrieval sequence will
be permitted at derated function
speeds. If the UGM detects a
chassis tilt condition with a tilt
sensor angle reading of
ABSOLUTE TRIP POINT 2 or
higher, Telescope Out will be
immediately inhibited.
The PLATFORM STA TION is active
and one or both inputs J7-7 and
J7-20 are LOW.
J7-7 and J7-
20 become
HIGH.

Changeover to PLATFORM MODE
will not
be permitted. If
PLATFORM MODE is the last valid
operating mode, the UGM will
assume the platform is attached.
The PLATFORM STA TION is active
and the UGM has not detected the
platform electrically attached.
The UGM
