9.15.2 Debug Functionality
The JLG Analyzer can be used to override the cab
joystick commands and hydraulic pump commands. This
feature can be accessed under DIAGNOSTICS/DEBUG
menu.
a. Cab Joystick Simulation
In the event of joystick failure, the analyzer can be used
to initiate signals that replicate joystick commands. Only
one functional direction is enabled at a time and when the
analyzer is being used, all commands from the cab
joystick are disregarded.
The Analyzer allows the following functions to be
simulated: Lift Up, Lift Down, Tele In, Tele Out, Fork Tilt
Up, or Fork Tilt Down. After selecting the function, use the
UP and DOWN arrow keys to provide the COMMAND
VALUE. The command range corresponds to that of the
joystick: 0-100%.
Note: Simulation of the joystick S1 button is not required
and Coordinated mode is prohibited.
b. Hydraulic Pump Override
The analyzer can be used to provide increased pump
flow for troubleshooting purposes. Use the UP arrow key
to increase pump flow. Use the DOWN arrow key to
decrease pump flow.
Note: A time limit of 5 minutes is imposed on this
feature. Unattended full volume pump flow can degrade
the oil and components. Therefore, after five minutes,
boom motion is disabled and the pump command is set
to 0% until power is cycled.
Machine power must be recycled for boom and pump
controls to be re-enabled.
