20 V-MAC Co-Pilot Operator's Manual CONDITION ENGINE DERATE ENGINE SHUTDOWN INDI- CATOR LIGHTS Engine Oil Temperature (EOT) Derate starts with 10% derate at 129°C (264.2°F) or more for 75% of a 4 second period. At 132°C (269.6°F) a 100% derate occurs. Engine shutdown if temperature rises to 135°C (275°F). Amber malfunction indicator lights when temperature is at 129°C (264.2°F). Red engine shutdown indicator lights when temperature is at 131°C (267.8°F). Afteretreatment Diesel Particulate Filter (DPF) Soot For Catalyzed ATS: Derate starts when soot trigger ratio is 1.4 and continues down to 20% derate. Amber malfunction indicator lights up when soot trigger ratio is 1.4. For Catalyzed ATS:
Torque is ramped down to 80% derate when soot trigger ratio is 1.7. Red engine shutdown indicator lights up when soot trigger ratio is 1.7. For Non-Catalyzed ATS: Derate starts when soot trigger ratio is 1.15. Amber malfunction indicator lights up when soot trigger ratio is 1.15. For Non-Catalyzed ATS: Torque is ramped down to 40% derate when soot trigger ratio is 1.20. Full derate occurs when soot trigger ratio is 1.22. Red engine shutdown indicator lights up when soot trigger ratio is at 1.22. Engine Turbocharger Wheel For MP8 engines, derate starts at 129,500 RPM. Full derate (100%) occurs at 130,500 RPM. No engine shutdown. No warning indicators. * - ATS (Aftertreatment System).
