6.
Next 1 minute cycle reduce the current or voltage below previous value.
7.
Check after 1 minute whether the MAXPAFD and MAXPRFD outputs are retaining the old
maximum value.
8.
Similarly the testing can be done for MAXPAFD and MAXPRFD outputs by changing the power
inputs directions through direction settings.
Verification of EAFALM & ERFALM outputs
1.
Repeat the above test steps 1 to 2.
2.
Set
tEnergy
setting as 1 minute and supply the IED with two-phase currents and voltages at
their rated value till 1 minute.
3.
Ensure that the active and reactive energy values are less than the
EALim
and
ERLim
setting
default values respectively.
4.
Check that EAFALM and ERFALM are low.
5.
Increase the supply currents or voltage in next 1 minute cycle such that the active or reactive
energy values are greater than the
EALim
and
ERLim
setting default values respectively.
6.
Check that EAFALM and ERFALM are high after 1 minute.
7.
Similarly the testing can be done for EARALM and ERRALM outputs by changing the power
inputs directions through direction settings.

Completing the test
M13906-301 v5
Continue to test another function or end the test by changing the
TESTMODE
setting to
Off
. Restore
connections and settings to the original values, if changed for testing purposes.

Multiple command and transmit MULTICMDRCV /
MULTICMDSND
SEMOD172432-5 v3
The multiple command and transmit function (MULTICMDRCV / MULTICMDSND) is only applicable
for horizontal communication.
Test of the multiple command function block and multiple transmit is recommended to be performed
in a system, that is, either in a complete delivery system as an acceptance test (FAT/SAT) or as parts
of that system, because the command function blocks are connected in a delivery-specific way
between bays and the station level and transmit.
Command and transmit function blocks included in the operation of different built-in functions must
be tested at the same time as their corresponding functions.

Binary signal transfer
M14951-2 v6
Prepare the IED for verification of settings as outlined in section
.
To perform a test of the binary signal transfer functions, the hardware (LDCM) and binary input and
output signals to transfer must be configured as required by the application.
There are two types of internal self-supervision of the binary signal transfer:
