Engine shutdown
There is risk of post boiling and of damage to the
turbocharger if the engine is switched off with-
out cooling. The power must not be switched off
before the engine has stopped.
If the engine is equipped with a battery master
switch and an SCR system, the SCR system must
run for a while after the engine has been switched
off to allow it to cool down. During this period
the power must not be cut using the battery mas-
ter switch.
The battery voltage must remain on for a few
seconds after the 15 voltage is switched off so
that the control units can store the values and
switch to standby mode.
10 prohibited engine shutdowns will cause a
torque reduction (70% of fuel volume). Reset the
engine by switching it off correctly once.
1. Run the engine without a load for a few min-
utes if it has been run continuously with a
heavy load.
2. Switch off the engine.
