Critical load control

The critical load control prevents the engine from stalling at low engine
speeds.
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 connecting an additional crane movement), the critical load con-
trol automatically reduces the hydraulic performance of the power units.
Here, the control lever movement is taken into account so that the power
unit speeds remain equal.
The slewing 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).
