Goals and Symptoms
64REF: Restricted Ground Fault is enabled but is showing as not recommended under the application screen.
Causes and Fixes
The 64REF function will be enabled when you are monitoring either a single ground current or a single neutral current. However after enabling the 64REF protection function and you navigate to the application screen the 64REF will be listed as not recommended for use
If you are seeing this you will need to change the one line diagram listed under CT-VT APS_SENSORS.
Once the one line is correctly configured you will be able to navigate to the application screen listed under the protection settings and 64REF will be displayed as normal.
