In addition to this, any operating parameter that would cause a Check Engine or Stop Engine Condition will be displayed on the EFC’s Information Center Message Display and an audible alarm will be activated.DDC- DDEC v Application&Instalation Manual 1/228 DDEC V APPLICATION AND INSTALLATION MANUAL 5 DDEC FEATURES Section. Pressing the IDLE switch will return the engine to it’s normal idle speed.Įngine RPM, Oil Pressure, Temperature, and System Voltage are displayed continu- ously while the EFC is in operation. Pump Pressure can be decreased in 4 PSI increments using the DEC switch. Pump Pressure can be increased in 4 PSI increments using the INC switch.
Pump Pressure can be controlled to a predetermined PSI by pressing the PRESET switch. The PRESSURE LED will be on to indicate that the EFC can be operated in the PSI Mode. THROTTLE READY LEDs (safety interlocks for pump operation have been established) must all be illuminated before any PSI adjustments can be made. The EFC must be on and the PUMP ENGAGED, OKAY TO PUMP Pressing the IDLE switch will return the engine RPM to it’s normal curb idle speed. Engine speed can be decreased in 25 RPM increments using the DEC switch. (Įngine speed can be increased in 25 RPM increments using the INC switch. The RPM LED will be on to indicate that the EFC will operate in the RPM mode.Įngine speed can be controlled to a predetermined RPM by pressing the PRESET switch. The EFC must be on and the Throttle Ready LED (interlocks necessary for increased throttle operations are active) must be illuminated before any RPM adjustments can be made.
