Completing the test

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

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.

Interlocking

Prepare the IED for verification of settings outlined in Section
to verify settings".
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.

Transformer energizing control XENCPOW

Prepare the IED for verification of settings outlined in Section
to verify settings".

Verifying the signals and settings

The voltage injection can be done using a common test equipment.
Verifying the high and low voltage settings
UHighLimit
1. Supply the IED with rated voltage value.
2. Decrease the voltage slowly and wait for 300 ms until the ULOW signal
appears.
3. Compare the voltage value with the set voltage low limit value.
