d) Creating a New Setpoint File
The enerVista 745 Setup software allows the user to create new setpoint files
independent of a connected device. These can be uploaded to a relay at a later date.
The following procedure illustrates how to create new setpoint files.
1. In the File pane, right click on ‘File’ and select the New Settings File item. The
enerVista 745 Setup software displays the following box will appear, allowing for
the configuration of the setpoint file for the correct firmware version. It is
important to define the correct firmware version to ensure that setpoints not
available in a particular version are not downloaded into the relay.
2. Select the Software Revision for the new setpoint file.
3. Configure the Installed Options as shown.
4. For future reference, enter some useful information in the Description box to
facilitate the identification of the device and the purpose of the file.
5. To select a file name and path for the new file, click the button beside the File
Name box.
6. Select the file name and path to store the file, or select any displayed file name
to update an existing file. All 745 setpoint files should have the extension ‘745’
(for example, ‘motor1.745’).
7. Click Save and OK to complete the process. Once this step is completed, the
new file, with a complete path, will be added to the enerVista 745 Setup
software environment.
e) Upgrading Setpoint Files to a New Revision
It is often necessary to upgrade the revision code for a previously saved setpoint file
after the 745 firmware has been upgraded (for example, this is required for
firmware upgrades). This is illustrated in the following procedure.
1. Establish communications with the 745 relay.
