The purpose of scanning is to detect high thermosignal values in polar data which could suggest presence of a friction spot in a bearing or other moving engine part Every peak in thermovoltage signal that exceeds 100 of DC alarm level is counted even if no alarm situation is detected System status messages are also extracted from scanned logfiles It is possible to use autoscanning as a one time routine or as a monitoring task performed regularly at a certain time interval for instance parallel to BCom Logger One time scan routine extracts information from logfiles collected over a certain time period Monitoring routine checks regularly for newly created logfiles and for changes in a logfile currently being written by BCom Logger and adds this new information to existing autoscan results FE 3s motcom loganalyser 1 0 5 3 Sa File Options Help Online monitoring BCom met Logfile autoscan Friction spot diagram status ram e C log _Engine1 com Am Last scan Single file analysis Reset diagram Finished directory autoscan ES i is met Heem M i Multiple file analysis astserterg Reset diagram I Show complete friction spot data regardless of diagram reset time bes ee eege Le OL Send alarm e mails View diagrams D Online monitoring Scan results Engine _Engine1 Operating hours 0 166667 h Main Alarm DC 0 Main Alarm AC
