RCL SETUP
The RCL setup is where the lifting configuration of the crane
is entered into the system. The RCL setup is required before
the crane can be operated.
When the crane ignition switch is turned on the RCL powers
up and displays the National Crane logo screen for a few
seconds followed by Screen 1 in the RCL setup sequence.
Screen 1
Is a basket attached to the boom or the tip of the jib nose?
Select 1 or 2.
- The ESC function here takes you to the Main Menu.
- If a basket is selected and the machine is shut
down, the RCL will restart without having to
complete the setup sequence. This is to enable
basket with radio remote operation.
Boom Configuration
If the crane is not equipped with a jib the following set up
screens will not appear. The system will detect that no jib has
been installed on the crane and by-pass these screens.
Select the RCL setup icon on the main menu to begin RCL
setup (Figure 7-2).
