RCL Display
The RCL display (5 Figure 4-3) is for the Rated Capacity
Limiter (RCL), see operating instructions and screen
displays in this manual.
The RCL provides the equipment operator with the
information required for the equipment to perform safely
within its design parameters. The RCL displays information
on length and angle of boom, platform height, and platform
reach.
The RCL continuously monitors these parameters and
provides the operator with an updated readout of the
equipment status. If an operational limitation condition is
approached, the RCL warns the operator with an alarm and
locks out the equipment functions that can aggravate the
situation.
