Loading setpoints
from a file
CAUTION:
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 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 3 Series 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 3 Series
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
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 error of the following type 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.
Uninstalling files and
clearing data
The unit can be decommissioned by turning off the power to the unit and disconnecting
the wires to it. Files can be cleared before uninstalling the EnerVista software or
350 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
•
EVENTS RECORDS > CLEAR
•
TRANSIENT RECORDS > CLEAR
