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, which is normally activated, will be deactivated.
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.
Ensure that the Test mode is activated.
Select Testing and Commissioning > Internal fault test > Test on to activate the
internal fault test.
