3.17 OUTRIGGER LIMIT SWITCHES
A mechanical limit switch at each outrigger senses the
outrigger has been set. The control system reports status
of each outrigger through the analyzer and also displays a
solid lit LED at the ground control when set. All outriggers
must be set prior to leveling. In addition, unset outriggers
are reported to the controls system, and the machine
functions will be cut back in the event two outriggers are
unset or if one outrigger is unset and the machine is tilted
(>2.0°).
Adjustment
Adjust the limit switch position so the switch is activated
when the outriggers are fully retracted (pin to the left side
of the slot) as shown below and the switch resets when
the outriggers are down and set (pin to the right side of
the slot).
