MISCELLANEOUS CONTROLS AND
INDICATORS
Fuse Panel
The Fuse Panel (1, Figure 3-14 and Figure 3-15) is located
behind the cab seat, on the cab fuse and relay panel
assembly. It contains up to 20 fuses that protect the various
electrical components of the crane.
Buzzer
The buzzer (2), located behind the cab seat, sounds when
the following conditions exist:
• the Ignition Switch is turned to RUN
• after the engine is started until the proper hydraulic
pressure is reached
• engine stop
• Emergency Stop Switch activated
• transmission service
• low brake pressure
• high hydraulic oil temperature
• high transmission oil temperature
• boom not synchronized
• low steer pressure condition (for CE units)
• hoist minimum wrap condition (for CE units).
Rated Capacity Limiter (RCL) Emergency
Override Switch (Non-CE Certified Cranes)
The RCL system, when programmed accurately, will lockout
the three craning functions—boom down, telescope extend,
and hoist up—when a lift is attempted at or above the crane's
capacity or when a two-block condition exists. Locking out
these three functions prevents the overload or two-block
condition from worsening.
The RCL emergency override switch (3, Figure 3-14) is a key
operated switch that is located inside the operator cab on the
panel assembly behind the seat. When actuated (turned
clockwise), the switch will override and prevent the RCL from
locking out the three craning functions (boom down,
telescope extend, and hoist up) should an overload or two-
block condition occur.
Overriding the RCL with this switch should only be done in
the case of an emergency or when servicing the boom.
WARNING
Loss of RCL Monitoring Hazard!
The RCL Emergency Override switch is to be used in
emergency situations only.
Do not operate the crane with the RCL overridden during
normal operations.
