Functions
2.1 General
Parameter 104 FAULT VALUE is used to specify whether the oscillographic fault recording should record
Instant. values or RMS values. If RMS values are stored, the available recording time increases by
the factor 10.
The parameter 145 df/dt Protect. establishes for the frequency change protection whether this is to
contain two or four stages or is Disabled.
Up to 8 SYNC function groups are available for the synchronizing function. They are enabled in addresses 016x
(x = 1 ... 8). Parameters 161 SYNC function 1 to 168 SYNC function 8 are used in addition to preselect
the mode of operation:
1ph Sync check corresponds to the classical synchronizing function with in each case single-phase connec-
tion of the voltages to be compared.
3ph Sync check corresponds to the classical synchronizing function with in each case multi-phase connec-
tion of the voltages to be compared.
NOTE
i i
A mixed parametrization of single-phase and three-phase synchrocheck between function groups is inad-
missible and leads to an error indication.
1,5chan.Synchr with the 7VE61 or 2chan.Synchr. with the 7VE63 corresponds to operation as a parallel
device. Connection is multiphase, processing of data command issuing is done 1
2-channel with the 7VE63.
NOTE

i
A mixed parametrization of three-phase synchrocheck and 1
possible due to the identical connection.
If a function is not needed,Disabled is set. A synchronizing function group thus rendered ineffective is
excluded in the menu item Synchronization, all other groups are displayed. The maximum number of the
existing synchronising function groups is established by the device variant (see section "Function description
of the synchronizing function").
