Fig 39.
When auto idle function has been selected via the switch
on the Facia Switch Panel (FSP) the engine will return
automatically to the auto idle setting if no services have
been selected for 5 seconds (default). This time can be
varied between 5 and 30 seconds via the SET menu on the
EMS.
A second press of this switch will disable the function. If the
upper, travel and boom lower pilot switches have been
inactive for the pre-set time period, the auto idle function
will operate and the engine revs will drop to the auto idle
value. The EMS will display the message "LOW IDLE".
The engine revs can be increased by pressing the auto idle
switch on the facia panel, or by the change of state of the
pilot switches (i.e. if excavator/travel service is selected).
When released from auto idle the engine revs return to the
setting of the throttle dial. By default auto idle is off.
The auto idle function is permanently active in auto mode.
The auto idle switch FS10 is disabled when in auto mode.
Note: One-touch idle overides auto idle
