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.
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.
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.
