6.1.2 Setting Groups
Purpose of Setting
Groups A setting group is a collection of setting values to be used for a particular application.
In the 7SA522 relay, four independent setting groups (A to D) are possible. The user
can switch between setting groups locally, via binary inputs (if so configured), via the
operator or service interface using a personal computer, or via the system interface.
A setting group includes the setting values for all functions that have been selected as
(QDEOHG
during configuration (see Chapter 5). Whilst setting values may vary among
the four setting groups, the selected functions of each setting group remain the same.
Multiple setting groups allows a specific relay to be used for more than one application.
While all setting groups are stored in the relay, only one setting group may be active
at a given time.
If multiple setting groups are not required, Group A is the default selection, and the
rest of this sub-section is of no importance.
If multiple setting groups are desired, address
*US&KJH237,21
must have
been set to
(QDEOHG
in the relay configuration. Refer to Chapter 5. Each of these sets
(A to D) is adjusted one after the other.
Copying Setting
Groups In most cases, only a few settings will vary from setting group to setting group. For this
reason, an option exists to copy stored setting values from one setting group to anoth-
er setting group using DIGSI
