Operation Manual
Document all the recorded data from the protection relay before
resetting the tripping and relay lockout functions.

Relay parametrization

Protection relay parameters are set via the LHMI or PCM600.
Setting parameters need to be calculated according to the electrical network
conditions and the electrical characteristics of the protected equipment. The
protection relay's settings need to be verified before the protection relay is
connected to a system.
Document all changes to parameter settings.
For more information, see the PCM600 documentation.

Settings for relay functionality

Function settings can be edited one by one by navigating to the individual setting
values, for example via the LHMI. The values in other setting groups should be
known before editing a certain setting value.
After completing the editing of setting group values, the new values are activated.
The user can either commit the edited values or discard them. Setting values can
also be copied from one setting group to another.

Settings for different operating conditions

Protection relay settings can be designed for various operation conditions by
defining different setting values to different setting groups. The active setting
group can be changed by the relay application or manually via the LHMI or
PCM600.
