Settings Group Selection

For different applications you can save the respective function settings in so-called Settings groups, and if
necessary enable them quickly.
The relay provides 2 groups of settings – Group number (Gn) 1 to 2. At any time, only one group of settings
can be active - SYSTEM CONFIG > Active Group setting. During operation, you can switch between
settings groups. The source of the switchover can be selected via a parameter.
You can switchover the settings groups via the following alternatives:
•
Via the relay fascia directly on the device
•
Via an online Reydisp Evolution connection to the device
•
Via binary inputs
•
Via a communication connection to the substation automation technology
The communication protocols IEC 60870-5-103, Modbus TCP can be used for switching the settings groups.
A settings group includes all switchable settings of the device. Except for a few exceptions (for example,
general device settings such as rated frequency), all device settings can be switched.
