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 Normal 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.
