The Protections-Advanced-Warnings menu includes the control threshold submenu in which the
parameters can be entered:

Defines whether the line-to-line voltages to be verified are those from
the internal sockets ( Measurement module) or from Ekip Synchrocheck ,
if present.

NOTE: if Ekip Synchrocheck is set, monitoring will refer to one
single voltage
