Technical Manual
Outputs WARNING and URES_WARNING indicate questionable quality data of
system measurements for selected U3P and URES, respectively.
Depending on the connected U3P channels to the voltage switch, the
Primary voltage settings between the source U3P must match.
Respectively, depending on the connected URES channels, the
Primary voltage settings between the source URES must match.
Setting validation for the primary voltages fails unless they are all
stored simultaneously to the protection relay.
