Computerized profiler control (CPC) systemThe computerized profiler control (CPC) system is an essential part of the machine. The controls of the CPC have many of the basic machine functions. The major functions of the CPC are listed below:
Propulsion of the machine
Rotor control
Steering of rear tracks
Engine underspeed (antistall) controlThe CPC also has several minor control functions. The control functions are listed below:
Backup alarm
Water spray system
Parking brake monitoring
CPC system diagnostics
CPC system calibrations
Engine shutdownThe CPC System provides electronic control of profiler functions. The system includes various inputs and outputs. The inputs and outputs are listed below:
Switches
Sensors
Electronic control module (ECM)
Solenoid valves
Backup alarm
relaysThe functions of the ECM are listed below:
Speed control
Direction control
Load control
Steering control
Rotor control
Water spray controlIn addition, the ECM provides fault detection, diagnostic display, calibration, backup alarm control, and engine shutdown. The ECM receives sensor signals such as operator input and engine speed. From this input information, the ECM makes decisions. The ECM acts on the decisions by adjusting the electrical current to the appropriate electrical devices such as solenoid valves and relays.
