Apply single-phase voltages to the inputs. H means a voltage of 100% UBaseLBus
and L means a voltage of 30% UBaseLine. Verify that correct output signals are
generated.
1. Connect the analog signals to the voltage inputs, in pair of two for U1 and
U2. (Inputs U3P - BB1, BB2, LN1, LN2)
2. Activate the binary signals according to the used alternative. Verify the
measuring voltage on the synchronizing check function SESRSYN. Normally
it can be good to verify synchronizing check with the same voltages and
phase angles on both voltages. The voltages should be verified to be available
when selected and not available when another input is activated so connect
only one voltage transformer reference at each time.
3. Record the voltage selection tests in a matrix table showing read values and
AUTOSYOK/MANSYOK signals to document the test performed.
15.11.1.5 Completing the test
Continue to test another function or end the test by changing the Test mode setting
to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.
15.11.2 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.
15.11.3 Interlocking
Prepare the IED for verification of settings outlined in section "Overview" and
section "Preparing for test" in this chapter.
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
