Outputs ALARM and URES_ALARM indicate bad quality data of system measurements

for selected U3P and URES, respectively.

Outputs WARNING and URES_WARNING indicate questionable quality data of system

measurements for selected U3P and URES, respectively.

Technical Manual

If the numbers of channels connected to U3P1...U3P4 and URES1...URES4

does not match with the number of connected SWITCH_TOx inputs, the

configuration of the function fails.

Depending on the connected U3P channels to the voltage switch,

Primary voltage settings between the source U3P must match.

Respectively, depending on the connected URES channels, the

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.
