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. Figure 17 Typical SEO Switch and Warning Lamps NOTE: The operator has the responsibility to take action to avoid engine damage. For fault codes and their meanings, see the DDEC VI MBE 900 Troubleshooting Guide (6SE580). 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). 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 engine will not require starting aids down to –15°C (5°F). Between (5°F) and (–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. 38 All information subject to change without notice.
