After successfully updating of the 750/760 firmware, the relay will not be in service and will require setpoint programming.
To communicate with the relay, the Slave Address, Baud Rate, and Parity will have to me manually programmed. When
communications is established, the saved setpoints must be reloaded back into the relay. See the following section for
details on loading saved setpoint files.
c) LOADING SETPOINTS FROM A FILE
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 Upgrad-
ing Setpoint Files to a New Revision on page 4–14 for instructions on changing the revision number of a
setpoint file.
The following procedure demonstrates how to load setpoints from a file:
1. Select the File > Open menu item.
2. 750/760PC will launch the Open window and list all filenames in the 750/760 default directory with the 750/760 exten-
sion. Select the setpoint file to download and click OK to continue.
