Releasing the function(s) to be tested

The user can release the function(s) to be tested. This is done in order to set only the tested func-
tion(s) in operation and prevent other functions from operating. The user can release the tested
function(s) by setting the corresponding parameter under BlockFunctions to NO in the local
HMI. When testing a function in this blocking feature, remember that not only the actual func-
tion must be activated, but the whole sequence of interconnected functions (from measuring in-
puts 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 sig-
nal on the corresponding function block is active, which depends on the configuration. The user
should therefore 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.
Note!
The function is blocked if the corresponding setting under the BlockFunctions menu remains on
and the TEST-INPUT signal remains active. All functions that where blocked or released from
previous test mode session are still valid when a new test mode session is entered.
Procedure
1.
Browse to the 'BlockFunctions' menu.
The BlockFunctions menu is located in the local HMI under:
Test/TestMode/BlockFunctions
2.
Browse to the function that should be released.
Use the left and right arrow buttons. Press 'E' when the desired function
has been found.
3.
Select 'No'.
4.
Press 'C' twice to leave the menu.
The 'Save TestGroup?' dialog appears.
5.
Choose 'Yes' leave the menu.

Checking the disturbance report settings

The terminal must be set in testmode (Operation=ON) to activate the disturbance report settings.
The user can select how the disturbances are indicated on the local HMI during the test. The user
can for example select if the disturbance summary should be stored, scrolled on the local HMI
or if LED information should be stored. Scroll to the disturbance report settings which are locat-
ed in the local HMI under:
