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
be individually blocked to ensure that no events are reported to a remote station during
the test. This is done by setting the parameter
EvDisable
to
Yes
.
Any function is blocked if the corresponding setting in the local HMI
under
Main menu/Test/Function test modes
menu remains
On
, that
is, the parameter
Blocked
is set to
Yes
and the parameter
TestMode
under
Main menu/Test/IED test mode
remains active. All functions
that were blocked or released in a previous test mode session, that is,
