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 logic for distance or overcurrent
protection ZCPSCH
M13868-2 v7
Prepare the IED for verification of settings as outlined in 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
tSendMin
minimum time.
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.
