IMPORTANT If a parameter is changed, it will be highlighted in red. This indicates that a
change has been made and this data must be uploaded into the base relay.
Once saved to the relay, the relay may request a reboot (restart) depending
on the setting changed.
Once all the settings for the 857-RAA have been completed, all these new
setting values must be uploaded into the relay by using the depressing the Write
All Settings to the Device icon within the SetPointPS software interface. See
publication 857-PM001. The alarm (start) and trip status information for each
channel enabled must be reviewed and mapped to an output device through
the Output Matrix in the 857 relay. See publication
the Output Matrix configuration.
