1- Rigging Mode - RaycoWylie i3500 Instruction Manual

4.4.7 Bypass/ Rigging (cont'd)
4.4.7.1 Rigging Mode (Maintenance/ Erection Mode)
It is often necessary with many cranes, when stowing or erecting the machine
to go outside the working ''envelope'' for which the crane manufacturer provides
ratings. For example, the boom stowed position may be outside the maximum
load radius or minimum boom angle specified on any load chart.
For this reason, RaycoWylie systems provide a Maintenance/ Erection mode,
where the boom may be lowered to or raised from the horizontal position without
the external alarm continuously sounding or the motion cut (if fitted) operating.
It is important to note the following points when in rigging mode:
• There are No lock-outs (except for the ATB)
• The ATB switch is still monitored.
• No audible alarms
• The Amber Light is on
• The speeds of the movement are not limited.
• A flashing rigging message is shown on the display.
• The rigging mode can be accessed when the SWL is zero.
The rigging mode is automatically exited when:
• The system is powered off or
• The SWL is greater than zero.
