• A master auto recloser is set with Priority = High.
• A slave auto recloser is set with Priority = Low.
The two auto reclosers can be checked individually by carefully applying RI , WAIT, and INHIBIT signals.
It is also possible to verify the two functions together by using circuit breaker simulating equipment for
two circuit breaker 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(79,5(0–>1)):x
2. Restore settings that may have been modified for the tests back to normal.
3. Disconnect the test switch, circuit breaker 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.
11.10.2.5 Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
11.10.3 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.

Commissioning manual
See the application manual for an illustration of typical interconnections.
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.
