An error message will occur when attempting to download a setpoint file with a
revision number that does not match the relay firmware. If the firmware has been
upgraded since saving the setpoint file, see Upgrading Setpoint Files to a New Revision,
above, for instructions on changing the revision number of a setpoint file.
The following procedure illustrates how to load setpoints from a file. Before loading a
setpoints file, it must first be added to the EnerVista SR3 Setup environment as described
in the section, Adding Setpoints Files to the Environment.
1.
Select the previously saved setpoints file from the File pane of the EnerVista SR3 Setup
software main window.
2.
Select the Offline > Edit Settings File Properties menu item and verify that the
corresponding file is fully compatible with the hardware and firmware version of the
target relay. If the versions are not identical, see Upgrading Setpoint Files to a New
Revision, above, for details on changing the setpoints file version.
3.
Right-click on the selected file and select the Write Settings File to Device item.
4.
Select the target relay from the list of devices shown and click Send. If there is an
incompatibility, an "Incompatible Device" error will occur:
If there are no incompatibilities between the target device and the settings file, the data
will be transferred to the relay. An indication of the percentage completed will be shown in
the bottom of the main window.
The unit can be decommissioned by turning off the power to the unit and disconnecting
the wires to it. Files can be cleared after uninstalling the EnerVista software or 345 device,
for example to comply with data security regulations. On the computer, settings files can
be identified by the .sr3 extension.
To clear the current settings file do the following:
1.
Create a default settings file.
2.
Write the default settings file to the relay.
3.
Delete all other files with the .sr3 extension.
4.
Delete any other data files , which can be in standard formats, such as COMTRADE or
.csv.
You cannot directly erase the flash memory, but all records and settings in that memory
can be deleted. Do this using these commands:
ACTUAL VALUES > RECORDS
•
EVENT RECORDS > CLEAR
•
TRANSIENT RECORDS > CLEAR
To upgrade the 345 firmware, follow the procedures listed in this section. Upon successful
completion of this procedure, the 345 will have new firmware installed with the factory
default setpoints.The latest firmware files are available from the GE Multilin website at
http:// www.GEmultilin.com.
EnerVista SR3 Setup software prevents incompatible firmware from being loaded into a
345 relay.
