Engine Shutdown; Electromagnetic Interference (Emi) - Doosan DX140R Shop Manual

Engine Shutdown

General Information
Allow the engine to idle 3 to 5 minutes before shutting it off after
a full-load operation. This allows adequate cool down of pistons,
cylinders, bearings, and turbocharger components.
Turn the ignition starter switch to the OFF position. If the engine
does not shut down, refer to "Troubleshooting Symptoms" on
page-195 in appropriate Operation and Maintenance manual.

Electromagnetic Interference (EMI)

General Information
Some engine applications utilize accessories (CB radios, mobile
transmitters, etc.) that generate and use radio frequency energy
that, if not installed and used properly, can cause
electromagnetic interference (EMI) conditions to exist between
the accessory and Cummins electronic controlled fuel system.
Cummins is not liable for any performance problems with either
the fuel system or the accessory due to EMI.
EMI is not considered by Cummins to be an engine failure and
therefore is not warrantable.
System EMI Susceptibility
Your Cummins product has been designed and tested for
minimum sensitivity to incoming electromagnetic energy.
Testing has shown that there is no engine performance
degradation at relatively high energy levels; however, if very
high energy levels are encountered, then some noncritical
diagnostic fault code logging can occur.
The fuel system EMI susceptibility level will protect your engine
from most, if not all, electromagnetic energy-emitting devices
that meet the Federal Communications Commission legal
requirements.
