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. 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.

7.5.4
Selecting IED blocked or IED test and blocked mode
The IED blocked mode and the IED test and blocked mode can be activated using the
LHMI. The Home button flashes green when the device is in the IED blocked or IED
test and blocked mode. By default, the test mode can only be changed from the LHMI.
Activation by remote client is possible, see the technical manual.
The test mode can be used for simulated testing of functions and outputs without
providing current inputs. The IED blocked mode can be used to block the physical
outputs to the process.
