APECS®4000 

 APECS 4000 expands Woodward’s line of programmable engine gover nors to address the needs of the stationary and mobile equipment industry. Enhanced input and output capability, combined with a flexible configuration, permits APECS 4000 to easily adapt to a wide  variety of engine governing applications.

Features:

 • User selectable isochronous or droop governing 

 • Analog input suitable for many uses:-Pedal position sensor with idle verification switch-Remote speed adjustments-Trim potentiometer 

 • Two switched inputs allow user to:-Program up to four discrete speeds and set ramp rates between speeds, or-Manually increase or decrease speed at preset rates with variable speed control 

 • PTO enable switch to select between pedal input and speed switches in mobile applications 

 • User selectable engine protection switch input (high coolant temperature, low oil pressure) 

 • Compatible with Woodward proportional actuators.

• Auxiliary output configurable in several ways:-Engine shutdown-Crank disable-Remote status lamp-Autocrank-PTO enabled lamp 

 • User-friendly calibration tool:-Programmable PID gains-Programmable speed setpoints, ramp rates-Easy to calibrate using APECS start-up wizard-Graphical or numerical real time display 

 • Current protection limits current to the actuator to protect from overheating. 

 • Status lamp (LED) signals normal engine running condition and diagnostics including overspeed and underspeed .

 • Sealed, tamper-resistant enclosure, chemical resistant to most automotive oils and liquids.
