Continue to test another function or end the test by changing the
TestMode setting to Off.
Restore connections and settings to their original values, if they were changed for testing
purposes.

Apparatus control APC
M13385-2 v4
The apparatus control function consists of four types of function blocks, which are connected
in a delivery-specific way between bays and to the station level. For that reason, test the total
function in a system, that is, either in a complete delivery system as an acceptance test (FAT/
SAT) or as parts of that system.
If a block/unblock command is sent from remote to function, while the IED is
shut down, this command will not be recognized after the start up, thus the
command that was sent prior to the shut down is used. In such cases, where
there is a mismatch, the user is advised to make a complete cycle of block/
unblock operations to align the statuses.

Tap changer control and supervision TCMYLTC, TCLYLTC
SEMOD175185-3 v12
Prepare the IED for verification of settings as outlined in section
in this chapter.
The automatic voltage control for tap changer, single control TR1ATCC is based on a
transformer configuration that consists of one tap changer on a single two-winding power
transformer.
