Section 10
Testing functionality by secondary injection
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.
10.9.2.5
Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Off. Restore
connections and settings to the original values, if changed for testing purposes.
10.9.3
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.

Function revision history
10.9.5
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 Mode = Off,
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.
10.9.6
Interlocking
Prepare the IED for verification of settings as outlined in section
section
Values of the logical signals are available on the local HMI under Main menu /Tests /Function
status /Control /Apparatus control /Interlocking . The Signal Monitoring in PCM600 shows the
same signals that are available on the local HMI.
The interlocking function consists of a bay-level part and a station-level part. The interlocking is
delivery specific and is realized by bay-to-bay communication over the station bus. For that reason,
test the function in a system, that is, either in a complete delivery system as an acceptance test (FAT/
SAT) or as parts of that system.
130
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.
