We use it for our 3 SG50’s. It has helped us for maintaining our AVR’s, Tuning the Big End Bearing Sensors and searching for alarms that don’t show up on the 901/902 computer screens. Also, it will let us generate a much more comprehensive list of events that we can send in if we are having issues that we can not find, via the log files you can export with it.
I think there is a manual for WECSplorer available online from Wartsila that would give you some more info.
