15.4.2 Application
The protection and control IEDs may have a complex configuration with many
included functions. To make the testing procedure easier, the IEDs include the feature
that allows individual blocking of all functions except the function(s) the shall be
tested.
This means that it is possible to see when a function is activated or trips. It also enables
the user to follow the operation of several related functions to check correct
functionality and to check parts of the configuration, and so on.
15.4.3 Setting guidelines
There are two possible ways to place the IED in the TestMode = On ” state. This means
that if the IED is set to normal operation ( TestMode = Off ), but the functions are still
shown being in the test mode, the input signal INPUT on the TESTMODE function
block must be activated in the configuration.
Forcing of binary output signals is only possible when the IED is in test mode.
