GROUP 1 OUTLINE
The NEW CAPO (Computer Aided Power Optimization) system controls engine and pump mutual power at an optimum and less fuel consuming state for the selected work by mode selection, auto- deceleration, power boost function, etc It monitors machine conditions, for instance, engine speed, coolant temperature, hydraulic oil temperature, and hydraulic oil pressure, etc
It consists of a MCU, a cluster, an ECM, EPPR valves, and other components The MCU and the
cluster protect themselves from over-current and high voltage input, and diagnose malfunctions caused
by short or open circuit in electric system, and display error codes on the cluster
