contains data pertaining to the following types of relay settings:
•
Device Definition
•
Relay Setup
•
System Setup
•
Protection
•
Control
•
Inputs/Outputs
Factory default values are supplied and can be restored after any changes.
The EnerVista SR3 Setup displays relay setpoints with the same hierarchy as the front
panel display.
Back up a copy of the in-service settings for each commissioned 345 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 EnerVista SR3 Setup 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 EnerVista SR3 Setup to the Relay, above.
2.
Select the desired device from the site list.
3.
Select the Online > Read Device Settings from Device 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 will request the name and
destination path of the setpoint file. The corresponding file extension will be
automatically assigned. Press Receive to complete the process. A new entry will be
added to the tree, in the File pane, showing path and file name for the setpoint file.
The EnerVista SR3 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.
