Stop Engine Override Switch - Detroit Diesel MBE 900 Operator's Manual

The engine will only operate at
reduced rpm until the battery voltage
reaches a point where the MCM will
no longer function and the engine
shuts down.
Should the AWL (Check Engine)
come on for any reason, the vehicle
can still be operated and the driver can
proceed to the required destination.
This condition should be reported
to an authorized Detroit Diesel
distributor or dealer.
NOTICE:
When the RSL (Stop Engine) comes
on, the computer has detected a
major malfunction in the engine that
requires immediate attention. It is
the operator's responsibility to
shut down the engine to avoid
serious damage.
The engine can be configured to
give a warning only, to ramp down
(reduce power) or to shut down.
Ramp down will reduce engine rpm
to a pre-determined speed, but will
not shut down the engine. With
the 30-second shutdown option, the
engine will begin a 30-second, stepped
power-down sequence until it shuts
down completely.
A "Stop Engine Override" can be
procured in case the vehicle is to
operate in a critical location.
All information subject to change without notice. (Rev. 04/08)

Stop Engine Override Switch

This feature allows the operator to
override the automatic stop engine
sequence.
This is done by pressing the Stop
Engine Override Switch every 15 to 20
seconds to prevent engine shutdown
from occurring.
NOTE:
The Stop Engine Override Switch and
the Diagnostic Request Switch are the
same.
NOTE:
Holding down the Stop Engine
Override Switch will not prevent the
engine shutdown sequence. You
must continue to reset the automatic
shutdown system by pressing the Stop
Engine Override Switch at intervals of
approximately 15 to 20 seconds.
It takes 30 seconds from the time the
automatic shutdown sequence begins
until engine shutdown. Therefore,
the operator must press the override
switch just prior to engine shutdown
and continue to do so until the vehicle
can be brought to a stop in a safe
location.
