for more information on this submenu.
The critical load control prevents the
engine from stalling at high power
requirements.
ECOS registers the currently available
motor output and the hydraulic
performance currently required by the
power units.
If the required hydraulic performance is
above the current motor output (e.g.
when conducting an additional crane
movement), the critical load control
automatically reduces the hydraulic
performance of the power units.
The swing gear is not influenced by the
critical load control.
The critical load control is switched on
together with the ignition. You should
only switch off the critical load control if
it is faulty (engine stalls or individual
power units can no longer be
controlled).
• Switching off: press button F7 until
the dot turns black
• Switching on: press F7 button (1)
until the dot (2) turns green.
