TROUBLESHOOTING / e-Shovel OUTLINE ICF (Information Controller) saves the input signals from various sensors and switches of the machine as data. Various input signals are recorded as “list of daily report data”, “list of frequency distribution data”, “list of total operating hours”, “list of alarm” and “list of failure” in ICF. The recorded data is downloaded to the personal computer and is uploaded to the center server via LAN, so that the data can be used as “e-Service”. The machine equipped with the optional satellite communication terminal sends the data to center server by using satellite communication. (As for the satellite communication system, refer to T5-3-24.) T5-3-1
