Fig 86.
Overload caution is used as a warning to the operator that
the machine is lifting a mass which is exceeding the safe
load capacity of the machine. An overload is indicated after
the overload pressure switch, ECU1 i/p 13 (A-27) has been
activated.
By default the overload override option is not enabled in A
(Auto), E (Economy) & P (Precision) modes until the
overload switch is selected. When selecting the overload
switch on the facia switch panel the EMS displays the
acknowledge message "OVERLOAD ON" and the staus
LED illuminates. A second press of the switch disables the
overload override function and the status LED is
extinguished.
When entering L (Lifting) Mode, the overload override
warning system is automatically activated. The status
indicator for FS6 illuminates. The operation of overload
switch will cancel the overload warning system.
If a overload condition is reached whilst the overload
function is selected, the EMS will display "OVERLOAD"
and the buzzer will sound.
