845 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL
The 845 displays relay setpoints with the same hierarchy as the front panel display.
Back up a copy of the in-service settings for each commissioned unit, so as to revert to the
commissioned settings after inadvertent, unauthorized, or temporary setting changes are
made, after the settings default due to firmware upgrade, or when the unit has to be
replaced. This section describes how to backup settings to a file and how to use that file to
restore settings to the original relay or to a replacement relay.
Setpoints must be saved to a file on the local PC before performing any firmware
upgrades. Saving setpoints is also highly recommended before making any setpoint
changes or creating new setpoint files.
The setpoint files in the window are accessed in the Files Window. Use the following
procedure to download and save setpoint files to a local PC.
1. Ensure that the site and corresponding device(s) have been properly defined and
configured as shown in Connecting to the Relay, above.
2. Select the desired device from the site list.
3. Select the Read Device Settings from the online menu item, or right-click on the
device and select Read Device Settings to obtain settings information from the
device.
4. After a few seconds of data retrieval, the software requests the name and destination
path of the setpoint file. The corresponding file extension is automatically assigned.
Press Receive to complete the process. A new entry is added to the tree, in the File
pane, showing path and file name for the setpoint file.
The EnerVista 8 Series Setup software provides the capability to review and manage a
large group of setpoint files. Use the following procedure to add an existing file to the list.
1. In the offline pane, right-click on Files and select the Add Existing Settings File item
as shown:
2. The Open dialog box will appear, prompting the user to select a previously saved
setpoint file. As for any other MS Windows® application, browse for the file to be
added then click Open. The new file and complete path will be added to the file list.
