Testing functionality by secondary injection
See the application manual for an illustration of typical
interconnections.
The two functions can be checked individually by carefully applying START, WAIT,
and INHIBIT signals.
It is also possible to verify the two functions together by using CB simulating
equipment for two CB circuits. There should be interconnections from the master to
the slave function, WFMASTER - WAIT, and UNSUCCL - INHIBIT, as shown in the
illustration referred to above.
Restoring equipment
After the tests, restore the equipment to normal or desired state. Check the following
items in particular:
1. Check the operation counters.
Reset the counters to zero, if that is the user's preference. The counter reset
function is found on the local HMI under Main menu/Reset/Reset counters/
AutoRecloser79,5(0–>1)/SMBRREC:x
2. Restore settings that may have been modified for the tests back to normal.
3. Disconnect the test switch, CB simulating arrangement and test circuits.
Reconnect any links or connection terminals, which may have been opened for
the tests.
4. Reset indications, alarms and disturbance recordings.
Clearing of the disturbance report can be done via the Disturbance Handling in
PCM600 or the local HMI.

Completing the test

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

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.
