Section 10
Testing functionality by secondary injection
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.
10.10.2.5

Completing the test

Continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
10.10.3

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.
10.10.4

Single command, 16 signals SINGLECMD

For the single command function block, it is necessary to configure the output signal to
corresponding binary output of the IED. The operation of the single command function
(SINGLECMD) is then checked from the local HMI by applying the commands with
Steady or Pulse , and by observing the logic statuses of the corresponding binary output.
Command control functions included in the operation of different built-in functions must be
tested at the same time as their corresponding functions.
10.10.5

Interlocking

Prepare the IED for verification of settings as outlined in section
section
182
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.
