Serviceable Fault Indication Screen
The Serviceable Fault Indication Screen appears if the JLG Control
System has sensed a fault that may require service attention by a
technician. As on the default screen, the display shows an indica-
tion of the fuel level, battery voltage, and engine rpm. In the
lower right hand corner, the numeric fault code with a safety alert
symbol is displayed. Multiple faults will display in succession.
Check the Service Manual for the specific fault code. In addition,
the locked/unlocked status of the jib is displayed on the lower
left corner of the screen.
NOTE: The fault indication can be shown regardless of the information
displayed above the orange line.
