The user can release the function(s) to be tested. This is done in order to set only the
tested function(s) in operation and prevent other functions from operating. The user can
release the tested function(s) by setting the corresponding parameter under BlockFunc-
tions to NO in the local HMI. When testing a function in this blocking feature, remem-
ber 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 and so on. Before starting a new test mode session the user should scroll through
every function to ensure that only the function to be tested (and the interconnected ones)
are set to NO. A function is also blocked if the BLOCK input signal on the correspond-
ing function block is active, which depends on the configuration. The user should there-
fore ensure that the logical status of the BLOCK input signal is equal to 0 for the tested
function. The user could also individually block event blocks to ensure that no events
are reported to remote station during the test.
