Settings
There are two alternative setting groups available, setting groups 1 and 2. Either of
these setting groups can be used as the actual settings, one at a time. Both groups
have their related registers. By switching between the setting groups, a whole group
of settings can be changed at the same time. This can be done in any of the following
ways:
Group configuration:
• via the HMI
• entering parameter V150 via serial communication
Group selection:
• switching between group 1 and group 2 is accomplished by means of a digital
input
Note!
Switching between setting groups through group selection has higher priority than
through group configuration.
The setting values can be altered via the HMI or with a PC provided with the Relay
Setting Tool.
Before the relay is connected to a system it must be assured that the relay has been
given the correct settings. If there is any doubt, the setting values should be read with
the relay trip circuits disconnected or tested with current injection; refer to section
Check lists for additional information.
