1. The transfer date of a setting file written to a D30 is logged in the relay and can be viewed via EnerVista UR Setup or
the front panel display. Likewise, the transfer date of a setting file saved to a local PC is logged in EnerVista UR Setup.
2. Comparing the dates stored in the relay and on the settings file at any time in the future will indicate if any changes
have been made to the relay configuration since the settings file was saved.
