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.
