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
parameter under Function test modes to
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
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
