11.4 Connecting the test equipment to the IED
M11744-2 v7
Connect the test equipment according to the IED specific connection diagram and the needed
input and output signals for the function under test. An example of a connection is shown in
figure 30 .
Connect the current and voltage terminals. Pay attention to the current polarity. Make sure
that the connection of input and output current terminals and the connection of the residual
current conductor is correct. Check that the input and output logical signals in the logic
diagram for the function under test are connected to the corresponding 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.

11.5 Releasing the function to be tested
M11413-2 v6
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
