If the numbers of channels connected to I3P1...I3P4 and
IRES1...IRES4 does not match with the number of connected
SWITCH_TOx inputs, the configuration of the function fails.
Outputs ALARM and IRES_ALARM indicate bad quality data of system measurements
for selected I3P and IRES, respectively.
Outputs WARNING and IRES_WARNING indicate questionable quality data of
system measurements for selected I3P and IRES, respectively.
Depending on the connected I3P channels to the current switch, the
Primary current settings between the source I3P must match.
Depending on the connected IRES channels, the Primary current
settings between the source IRES must match.
Setting validation for the primary current fails unless they are all
stored simultaneously to the protection relay.
