Tilt; Critical Vehicle Interlock Scenarios; Outriggers - JLG T350 Troubleshooting Manual

INTRODUCTION
A.11 TILT
X and Y axis tilt are combined through a calculation to form the tilt value used by the control system. The machine is consid-
ered "Tilted" whenever this calculated tilt value is above 2 degrees from calibrated level, zero tilt.
An outrigger is considered set when the pivot pin slides up and closes the outrigger limit switch.
The ground control panel outrigger LEDs blink whenever they are set, but the machine is tilted. Once the outriggers are set
and the machine is not tilted, the outrigger LEDs remain on, steady.
The platform outrigger LED blinks till all four outriggers are set, then lights steady. The platform tilt LED lights whenever the
machine is tilted.
Orientation
The Ground Module shall be mounted such that the Tilt Sensor's X-Axis responds to Side-to-Side tilt of the vehicle, while the
Y-Axis responds to Front-to-Back tilt of the vehicle. The following table is offered to clarify orientation.
A.12 CRITICAL VEHICLE INTERLOCK SCENARIOS
The following scenarios have been identified that require unique vehicle interlocks. For readability, the circumstances
involved with entering and leaving these situations have been isolated here.
RETRIEVAL-A
Retrieval-A forces the user to stow the boom if the Tilt Warning is ignored and critical stability situations are reached. This
scenario is INACTIVE at Power-up.
It becomes ACTIVE when the machine is ELEVATED (transport switch OPEN) AND CRITICALLY TILTED 4.5 degrees or more.
It is INACTIVE otherwise.
RETRIEVAL-B
Retrieval-B forces the user to stow the boom if the Outrigger Unset Warning is ignored and critical stability situations are
reached. This scenario is INACTIVE at Power-up.
It becomes ACTIVE under the following circumstances. It is INACTIVE otherwise.
·The vehicle is Elevated AND One Outrigger is Unset AND the vehicle is TILTED
·The vehicle is Elevated AND Two Outriggers are UNSET.
A.13 OUTRIGGERS
Some machine software may refer to the Outriggers (O/R) as Lifting Jacks (L/J).
