continue to test another function or end the test by changing the
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
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.
11.10.5

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.

Scheme communication

11.11.1 Scheme communication logic for distance or overcurrent
protection ZCPSCH
Prepare the IED for verification of settings as outlined in section
section
Check the scheme logic during the secondary injection test of the impedance or overcurrent
protection functions.
Activation of the different zones verifies that the CS signal is issued from the intended zones.
The CS signal from the independent tripping zone must have a
Check the tripping function by activating the CR and CRG inputs with the overreaching zone
used to achieve the CACC signal.
It is sufficient to activate the zones with only one type of fault with the secondary injection.
11.11.1.1

Testing permissive underreaching

1. Activate the receive (CR) signal in the IED.
2. Apply healthy normal load conditions to the IED for at least two seconds.
3. Apply a fault condition within the permissive zone.
