Selecting internal fault test

The internal fault may be tested by using the LHMI. When enabling the test, the
internal relay fault output contact is activated, the green Ready LED will be blinking
and internal fault test indication is shown on the LHMI. See Technical Manual for
internal relay fault output contact location.
Differing from real internal fault situation, the other output contacts
are not released and locked during the test. In other words, protection
functions can operate and trip the outputs when the internal fault is
tested.
