850 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL
• Attempting to enter and save a setting value which exceeds the range gives a
warning dialog box. (note the value is not replaced with the maximum value of the
setting). The user must correct the setting value and save to proceed.
Example: The Phase CT Primary value has a setting range of 1 to 12000, but the user
enters 12001 and tries to save it. Quick Setup displays a warning dialog. Pressing OK
leaves the setting value at 12001, but not 12000 (max. value) as is the case with other
views.
To upgrade the 850 firmware, follow the procedures listed in this section. Upon successful
completion of this procedure, the 850 will have new firmware installed with the factory
default setpoints.The latest firmware files are available from the GE Grid Solutions website
at http://www.gegridsolutions.com.
EnerVista 8 Series Setup software prevents incompatible firmware from being loaded into
an 850 relay.
Note that uploading firmware on a Wi-Fi interface is not allowed.
Note that uploading firmware to a relay having a Communications card must be done
with "Port 4 operation" configured as independent.
Before upgrading firmware, it is very important to save the current 850 settings to a file on
your PC. After the firmware has been upgraded, it will be necessary to load this file back
into the 850. Refer to Downloading and Saving Setpoints Files for details on saving relay
setpoints to a file.
