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.
2. 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.
ROBWAY recommends that the over-ride key-switch
be switched off (ie, normal position) at all times and
the over-ride key held by the site-supervisor.

modes.
