6.2.4.

Used in Calibration mode to cancel incorrectly entered data or to escape out of various menus
6.2.6.
Tare Key
The RCI-1550 allows the operator to TARE out the weight of the hook, rope and accessories of the
selected winch if required. This is a toggle function that turns on or off depending on its current
state and is a function of the currently winch selected.
If the TARE indicator is illuminated then the displayed load is the total weight minus the accessory
weight. When TARE is next pressed, the displayed load reverts to the total. If the TARE indicator
is off then the actual load shown in the load window at the time of pressing the TARE button will be
stored in the system as the tare load.
Please note that when the TARE function is active,
the %SWL is still determined by the total load,
irrespective of what is currently displayed.
All tared weights are removed on system start-up.
6.2.7.
Rigging Key
Rigging mode is operator selectable via the MENU button and scrolling to Rigging Mode,
alternatively the rigging key on the front panel can be used to initiate rigging.
There are two forms of Rigging mode.
 General Rigging mode, where motion-cut is over-ridden (if fitted) to luff down and hook up
and tele-out. This mode is ONLY intended for use during crane lay-down or setup.
If after this function is initiated, the boom is raised more than 10 degrees, this function will
reset to normal crane operation. This is necessary to ensure overall safe crane operation.
 Temporary/ATB Rigging mode, which is essentially the same as normal rigging mode with
the exception that it over-rides motion cuts for only a limited period or time. This mode is
intended to allow the operator to over-ride the display in special circumstances (eg. need to
raise through ATB switch to gain some height etc.).
This operator selectable mode is provided to enable crane hoist rope reeving which would otherwise
cause alarms and motion-cut (if fitted). When selected, the display automatically chooses whether full
rigging mode or temporary rigging mode is enabled. Full rigging mode will only be enabled when the
crane is NOT positioned in a legal lifting position.
Rigging mode will be cancelled when the operator presses the cancel button. If errors become active
in rigging mode they will not be displayed but the audible will sound. The ACK button can be used to
silence them for approximately 5 minutes (according to the setting for the Acknowledge Timeout).
If normal crane operation is overridden the LCD will display a message indicating “Temporary Over-
Ride” is occurring. The override will end if the operator presses cancel or 10 seconds have expired.
If an attempt is made to enter rigging mode but there is a load on the hook which exceeds the rigging
threshold, or the boom length exceeds the rigging length threshold, then a message stating this will be
displayed. The main menu will subsequently be displayed after approx. 3 seconds.
