GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
USING THE RATED CAPACITY LIMITER
DISPLAY MODULE (RDM)
NOTE: Refer to Rated Capacity Limiter Display Module
(RDM), page 3-21 for additional information.
The Rated Capacity Limiter (RCL) is an electro-mechanical
sensing system designed to alert the crane operator of
impending capacity when the system has been accurately
programmed. When an overload condition is sensed, the
system provides the operator with a visual and audible
warning, and locks out the controller functions to prevent
raising and lowering the boom, extending the boom, or
raising the main or auxiliary (optional) hoist ropes.
The RCL Setup Screen (Figure 4-177) appears on the RDM
when the ignition key is set to the On position.
From the RCL Setup Screen, the operator can program the
RCL either by entering a rigging code number from the Load
Chart Manual or by entering the crane configuration using
the setup wizard
Enter Rigging Code
For a complete rigging code input, operator must enter,
confirm and accept the rigging code and the reeving.
There are two ways of entering the current rigging mode.
• Either enter the individual components (1, Figure 4-178)
to (8) one after the other.
• Or enter the RCL code (9) and the reeving (8).
The newly entered rigging mode must then be confirmed
• with (10)
The following section describes the input procedure based
on the individual components. If you want to enter the rigging
mode based on the RCL code, refer to Entering the RCL
Code, page 4-163.
Entering Individual Components
With this type of input, select all the components of the
rigging mode one after the other.
When re-entering the rigging mode completely, you can
prevent already entered components from changing by
making entries in the following order:
- Counterweight (2, Figure 4-179)
- Boom system (1)
- Outrigger span (3)
DANGER
Electronic equipment on this crane is intended as an aid
to the operator. Under no condition should it be relied on
to replace the use of Load Charts and operating
instructions.
Sole reliance on these electronic aids in place of good
operating practices can cause an accident.
DANGER
Overload/Tipover hazard!
The RCL is an operator aid. If it is programmed
incorrectly, the system may not warn the operator of
impending overload and may not activate function
lockouts.
Ensure the RCL is properly programmed to correspond to
the actual crane configuration being used.
