MBE 900 ENGINE 2007 OPERATOR'S GUIDE Engine brakes will supply braking power even when in Cruise Control. The MCM will control the amount of engine braking with respect to the Cruise Control set speed. The maximum amount of braking (low, medium, high) is selected with the dash switches. PERSONAL INJURY To avoid injury from engine shutdown in an unsafe situation, ensure the operator knows how to override the stop engine condition on a DDEC-equipped unit. Engine Protection The DDEC engine protection system monitors all engine sensors and electronic components, and recognizes system malfunctions. If a critical fault is detected, the AWL (Check Engine) and RSL (Stop Engine) illuminate.
The malfunction codes are logged into the MCM's memory. NOTICE: Engines equipped with the power-down/shutdown option have a system override button or switch to allow engine operation for a short period of time. Using the override button so the engine does not shutdown in 30 seconds but operates for an extended period may result in engine damage. The standard parameters which are monitored for engine protection are: low coolant level, high coolant temperature, low oil pressure, and high oil temperature.
California Engine Idle Limiting This system features a 30-second, stepped-power shutdown sequence or an immediate speed reduction without shutdown in the event a major engine malfunction occurs, such as low oil pressure, high oil or coolant temperature, or low coolant level. In order to meet the California Engine Idle Limiting Standard, an engine idle shutdown feature has been built into the DDEC VI Engine Control Strategy.
When the California Engine Idle Limiting feature is enabled, the engine will generally shut down after five minutes of continuous idling when the transmission is in neutral or park and the parking brake is set or after fifteen minutes when the transmission is in neutral or park and All information subject to change without notice.
