SERIES 60 ON-HIGHWAY ENGINE OPERATOR'S GUIDE Engine Protection NOTICE: The DDEC engine protection system monitors all engine sensors and electronic components, and recognizes system malfunctions. If a critical fault is detected, the AWL and RSL illuminate. The malfunction codes are logged into the ECU's memory. 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. Idle Shutdown Timer This feature is an optional 1 100 minute idle shutdown system. Its purpose is to conserve fuel by eliminating excessive idling and allowing a turbocharger cool-down period. To activate the shutdown, the transmission must be in neutral with the vehicle parking brakes set and the engine in idle or fast-idle mode. 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.
Cruise Control PERSONAL INJURY Cruise Control is available with any DDEC engine. Cruise Control will operate in either Engine or Vehicle Speed Mode and maintain a targeted speed (MPH or RPM) by increasing or decreasing fueling. The targeted speed can be selected and adjusted with dash-mounted switches. See Figure 5. 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.
