binary inputs and outputs of the IED under test.
To ensure correct results, make sure that the IED as well as the test
equipment are properly earthed before testing.

9.5 Releasing the function to be tested
Release or unblock the function to be tested. This is done to ensure that only the
function or the chain of functions to be tested are in operation and that other functions
are prevented from operating. Release the tested function(s) by setting the
corresponding
Blocked parameter under Function test modes to No in the local HMI.
When testing a function in this blocking feature, remember that not only the actual
function must be activated, but the whole sequence of interconnected functions (from
measuring inputs to binary output contacts), including logic must be activated. Before
starting a new test mode session, scroll through every function to ensure that only the
function to be tested (and the interconnected ones) have the parameters
Blocked and
eventually EvDisable set to No and Yes respectively. Remember that a function is also
blocked if the BLOCK input signal on the corresponding function block is active,
which depends on the configuration. Ensure that the logical status of the BLOCK
input signal is equal to 0 for the function to be tested. Event function blocks can also
