4.3 Maintenance
OPT100 DGA Monitor does not require visits to the installation site for preventive maintenance.
There are no consumables or components that must be replaced according to a fixed schedule.
You can check the status of the DGA monitor and update its configuration remotely through
the browser-based user interface. Software of the DGA monitor can be updated remotely as
well.
Indications of the DGA monitor's status are also available to your SCADA system through the
communication interfaces (for example, Modbus). If a problem with the DGA monitor is
indicated, check the user interface.
4.4 Updating DGA Monitor Software
• Software update file for DGA monitor
Software update does not delete the data stored on the DGA monitor.
Configuration settings are also retained where possible, but you should check
them after the update.
Updated software may include improvements to the measurement algorithm.
These updates are only applied to new measurement cycles after the update,
which may cause some discontinuity in the measured gas levels even if the
concentration of gases in the measured oil has not changed. Vaisala recommends
starting autocalibration manually after a software update.
