Releasing the function to be tested
M11413-2 v7
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
