When the test handle is inserted into the test switch, all current circuits on
the transformer side are short-circuited and all voltage circuits are opened,
except for terminal 1 and 12, which are used for dc supply of the terminal.
The testing equipment connected to the test handle is automatically con-
nected to the terminal.
You can plug the test handle into the test switch or withdraw it from the
test switch to the intermediate position. In this position, the trip circuits
are blocked, but the voltage and current circuits are connected to the relay.
You can plug the test handle into the test switch or remove it from the test
switch completely by releasing the top and bottom latches.
4.4 Functional test All included functions are tested according to the test instructions in each
function description. You can block functions individually during the test,
so that only the function that is to be tested is active. In this way, you can
test slower back-up measuring functions without the interference of faster
measuring functions. You can also test the terminal without changing the
configuration and the setting of the terminal.
The functions are blocked on the built-in MMI at:
Test
TestMode
BlockFunctions
The setting is only valid at test mode. If the functions are blocked in this
menu, they are blocked only while the terminal is in test mode. When
using this blocking feature, remember that for testing a function, you must
activate not only the function, but the whole sequence of functions that are
interconnected in a sequence (from measuring inputs to binary output
contacts) including logic, and so on.
4.5 Test termination When the whole test is finished, reconfigure the terminal into normal
operating mode on the built-in MMI at:
Test
Test Mode
Operation
Set Test/Mode/Operation = Off, and save the test mode setting. The yel-
low LED goes out.
