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.

Apparatus control APC
M13385-2 v7
The apparatus control function consists of four types of function blocks, which are connected
in a delivery-specific way between bays and to the station level. For that reason, test the total
function in a system, that is, either in a complete delivery system as an acceptance test (FAT/
SAT) or as parts of that system.
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.
The complete apparatus control function is not included in this product.
9.6.4
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.

Prepare the IED for verification of settings outlined in Section
This function is functionality tested together with other protection functions (line differential
protection, earth-fault overcurrent protection, and so on) within the IED. It is recommended
that the function is tested together with the autorecloser function, when built into the IED or
when a separate external unit is used for reclosing purposes.

3 phase operating mode
SEMOD54375-106 v10
1.
Check that
AutoLock and TripLockout are both set to Off.
2.
Initiate a three-phase fault.
An adequate time interval between the faults should be considered, to overcome a
reclaim time caused by the possible activation of the autorecloser function SMBRREC.
