2.1.3.4 Settings
Two alternative setting groups, 1 and 2, are available for the relay. Either of these
setting groups can be used as the actual settings, one group at a time. Both the groups
have their related registers. Switching between the setting groups 1 and 2 enables
changing a whole group of settings at the same time. This can be done in the
following ways:
1. With command V150 via serial communication.
2. By means of an external binary input BI.
Values of the settings are altered with a personal computer provided with the Relay
Setting Tool.
Before the relay is connected to a system, one must assure that the relay has been
given correct settings. If there is any doubt about the settings, the setting values
should be read with the relay trip circuits disconnected or tested with current
injection. Refer to “Check lists”.

1)
At inverse-time characteristic the relay allows settings above the set limit.
However, applying settings above the limit might damage the relay.
2)
The stage can be set out of operation with SGF switches. This state is indicated
with the reading “999” when parameters are read over the SPA bus.
