Figure 16.4 DES Operation
Note: The use of the User Defined Shutdown input to the engine ECM to
override DES will be logged within engine ECM memory as an abnormal
engine shutdown event. This information may be used to refuse
warranty where excessive use of the DES override has occurred.
16.3.1.2 Delayed Engine Shutdown Configuration
Perkins EST can be used to enable / disable the Delayed engine Shutdown
feature. As default the feature is set to ‘Not Installed’ for all 1206F engines. It
is recommended that where possible the DES feature is enabled to provide
protection against high system temperature engine shutdown events.
The maximum DES run time is configured by setting the Perkins EST
parameter “Delayed Engine Shutdown Maximum Time”. This value can be
set to any value between 4 and 15 minutes with a default of 15min. This
value indicates the maximum time DES could run before shutting down the
engine. The system will however shutdown the engine in less time if cool and
the purge has been completed.
