Stop Engine Override Option; Cold Weather Operation - Detroit Diesel MBE 900 Operator's Manual

OPERATING INSTRUCTIONS FOR STARTING THE ENGINE
□ Complete fault codes are
transmitted and can be read
using DDDL 7.0 or latest version.
□ If the fault is serious enough to
impair normal operation, the
electronic engine system switches
over to limp home mode. The
limp home speed is dependent
on MCM parameters and could
be idle speed or 1000 rpm. This
allows you to move the vehicle to
a service location.
For fault codes and their meanings,
see the DDEC VI MBE 900
Troubleshooting Guide (6SE580).
Stop Engine Override
Option
The Stop Engine Override Option is
used for a momentary override. The
MCM will record the number of times
the override is activated after a fault
occurs.
Momentary Override – A Stop
Engine Override (SEO) switch is used
to override the shutdown sequence
(see Figure 17). This override resets
the 60 second (30 seconds for oil
pressure) shutdown timer, restoring
power to the level when the RSL (Stop
Engine) was illuminated. The switch
must be recycled after five seconds to
obtain a subsequent override.

The operator has the responsibility to
take action to avoid engine damage.

Cold Weather Operation

Special precautions must be taken
during cold weather. To protect your
engine, special cold weather handling
is required for fuel, engine oil, coolant,
and batteries. For detailed information
on the grid heater and optional fuel
filter heater, refer to the MBE 900
Service Manual (6SE9007).
The engine will not require starting
aids down to –15°C (5°F). Between
–15°C (5°F) and –25°C (–13°F) a
grid heater is required. Temperatures
below –25°C (–13°F) will require a
grid heater, block heater, and oil pan
heater. An optional fuel heater is
available.
