Operational Fault - Envelope Violation Fault Screen
The Envelope Violation Fault Screen appears if the JLG Control
System has sensed that the boom is encroaching the edge of the
forward or backward operating envelope (hydraulics are sus-
pended). This screen will remain until the operator operates one
of the controls highlighted on the screen to correct the condition.
In the lower right hand corner, a check mark in a green circle indi-
cates no serviceable faults are present. If a serviceable fault is
present, the numeric fault code with a safety alert symbol is dis-
played. Multiple faults will display in succession. Check the Ser-
vice Manual for the specific fault code. This screen will show
when the Boom Control System Light is illuminated.
