Up to four independent setting groups can be created for establishing the device's
function settings. During operation, the user can locally switch between setting groups
using the operator panel, binary inputs (if so configured), the operator and service in-
terface per PC, or via the system interface. For reasons of safety it is not possible to
change between setting groups during a power system fault.
A setting group includes the setting values for all functions that have been selected as
(QDEOHG during configuration (see Subsection 2.1.1.2). In relays 7SA522 four inde-
pendent setting groups(A to D) are available. Whereas setting values and options may
vary, the selected scope of functions is the same for all groups.
Setting groups enable the user to save the corresponding settings for each applica-
tion. When they are needed, settings may be loaded quickly. 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. Then, the
rest of this section is not applicable.
If multiple setting groups are desired, the setting group change option must be set to
*US &KJH 237,21 = (QDEOHG in the relay configuration (Subsection 2.1.1.2,
address ). For the setting of the function parameters, you can configure each of
the required setting groups A to D, one after the other. A maximum of 4 is possible.
Please refer to the SIPROTEC
