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/Clear/Clear counters/
SMBRREC(79,0->1)
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 must be done via the Disturbance Handling
in PCM600.
6.7.2.5 Completing the test
Continue to test another function or end the testing by setting the parameter
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No under Main menu/
Tests/Function test modes/Control/SMBRREC(79,0->1)/X:SMBRREC for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter Blocked to Yes, for each individual function that has been tested.
6.7.3 Interlocking
Prepare the IED for verification of settings as outlined in
5.1 "Preparing the IED to
verify settings".
Values of the logical signals are available on the local HMI under Main menu/
Tests/Function status/Control/<Function>/<1:Function>. 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.
6.7.4 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.
