Fault diagnosis memory of civil engineering heavy equipment excavator

摘要

The present invention relates to a fault diagnosing storage device for a civil engineering heavy equipment, and more particularly, to a controller for an excavator which self-diagnoses various sensors, functional parts and combinations on a line in accordance with an electrical signal, It has a function to categorize the fault diagnosis result to the monitor unit which is transmitted to the controller and store it in the memory, so that it is possible to cope with the fast and accurate maintenance service in case of non-reproducible failure due to contact failure of the electric line or external noise. Fault diagnosis memory of a heavy construction equipment excavator.
