Selecting the 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 is flashing and
internal fault test indication is shown on the LHMI. See the technical manual for the
internal relay fault output contact location. The internal fault can only be activated by
using the LHMI.
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.
