6.1.3 Supervision of spools
If a valve spool movement is greater than the
equivalent lever or joystick movement on the
controller, a safety function is tripped, and all
crane movements stops.
This occurs if a control lever on the valve is
moved while the remote control is engaged.
6.1.4 APO Automatic power off
APO is a function which automatically switches
off the power to the control system. It consists of:
1. Timeout controlled power off. (30 minutes
by default).
2. Parking brake controlled power off.
Through the vehicle’s parking brake, APO
offers a safety function which ensures that
the control system is off when the vehicle
is moving. When parking brake is released,
the control system receives a signal and
shuts OFF.
For emergency operation
During 5 seconds, it is possible to activate
the control system by pushing the ON/OFF
button on the user panel.
6.1.5 ADO Automatic dump function
If a lever is not moved for 3 seconds, this
function diverts the oil to the tank, thereby
preventing the oil from overheating. The next
lever movement stops the dumping and it func-
tions as normal.
