ABB RED670 User Manual

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.
11.10.4 Single command, 16 signals SINGLECMD
SEMOD172444-5 v3
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
M11755-2 v8
Prepare the IED for verification of settings outlined in Section
"Preparing the IED
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.
11.11 Scheme communication
SEMOD53569-1 v1
11.11.1 Scheme communication logic for distance or overcurrent
protection ZCPSCH
M13868-2 v7
Prepare the IED for verification of settings outlined in Section
"Preparing the IED
to verify settings".
Check the scheme logic during the secondary injection test of the impedance or
overcurrent protection functions.
