Adjusting Electronic Joysticks
If the meter-in dead band of a joystick function is too fast or
too slow or its maximum function speed is slower or faster
than design specifications, adjustments can be made using
the Grove CAN-link service software providing the following
have been performed:
• All function pressures have been set correctly following
the procedures in the Hydraulic System, page 2-1.
• Correct function speeds cannot be attained by
adjustments made through the crane control system
(CCS) control screens.
• Correct function control cannot be attained by
adjustments made through the CCS control screen
selectable curves.
To adjust the meter-in dead band and maximum function
speed of a joystick, a Windows-based PC, CAN-link service
software (9999102409), and a connection cable (80059224)
are required. The CAN-Link service software and connection
cable are available through Manitowoc Crane Care to those
service technicians who have attended the Grove New
Technology training course.
FAULT CODES
The crane control system (CCS) monitors the engine,
transmission, and crane functions to ensure they are
functioning properly. If a malfunction is detected within any of
these areas, the crane control system display will illuminate
the engine system warning icon for engine and transmission
faults, or the crane error icon for any crane function faults.
Both of these icons are located on the main menu screen of
the CCS display.
To access the main menu screen of the CCS display, select
the lower left button of the jog-dial (1, Figure 3-12). Note: the
jog-dial icon (2, Figure 3-12) must be present on the crane
control display to select the main menu with the jog-dial. The
main menu can also be accessed by selecting the main
menu button (3, Figure 3-12).
Select the engine system warning icon (4, Figure 3-13) to
view engine and transmission errors (5, Figure 3-13) or
select the crane error icon (6, Figure 3-14) to view crane
control system errors (7, Figure 3-14).
A list of all fault codes and their definitions are available
through Manitowoc Crane Care to those service technicians
who have attended the Grove New Technology training
course.
