Restoring equipment M12400-190 v6After the tests, restore the equipment to normal or desired state. Check thefollowing items in particular:1. Check the operation counters.Reset the counters to zero, if that is the user's preference. The counter resetfunction is found on the local HMI under Main menu/Reset/Reset counters/AutoRecloser79,5(0–>1)/SMBRREC(79,5(0–>1)):x2. Restore settings that may have been modified for the tests back to normal.3. Disconnect the test switch, circuit breaker simulating arrangement and testcircuits.Reconnect any links or connection terminals, which may have been openedfor the tests.4. Reset indications, alarms and disturbance recordings.Clearing of the disturbance report can be done via the Disturbance Handlingin PCM600 or the local HMI.10.9.2.5 Completing the test M12400-218 v5Continue to test another function or end the test by changing the TESTMODEsetting to Off. Restore connections and settings to their original values, if they werechanged for testing purposes.10.9.3 Apparatus control APC M13385-2 v6The apparatus control function consists of four types of function blocks, which areconnected in a delivery-specific way between bays and to the station level. For thatreason, test the total function in a system, that is, either in a complete deliverysystem as an acceptance test (FAT/SAT) or as parts of that system.If a block/unblock command is sent from remote to function, whilethe IED is shut down, this command will not be recognized afterthe start up, thus the command that was sent prior to the shut downis used. In such cases, where there is a mismatch, the user isadvised to make a complete cycle of block/unblock operations toalign the statuses.10.9.4 Single command, 16 signals SINGLECMD SEMOD172444-5 v3For the single command function block, it is necessary to configure the outputsignal to corresponding binary output of the IED. The operation of the singlecommand function (SINGLECMD) is then checked from the local HMI byapplying the commands with Mode = Off, Steady or Pulse, and by observing thelogic statuses of the corresponding binary output.
