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
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.

Station communication
11.13.1
Multiple command and transmit MULTICMDRCV / MULTICMDSND
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
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:
•
The I/O-circuit board is supervised as an I/O module. For example it generates FAIL if the board is
not inserted. I/O-modules not configured are not supervised.
•
The communication is supervised and the signal COMFAIL is generated if a communication error is
detected.
Status for inputs and outputs as well as self-supervision status are available from the local HMI under
•
Self-supervision status: Main menu /Diagnostics /Internal events
•
Status for inputs and outputs: Main menu /Test /Function status , browse to the function group of
interest.
•
Remote communication related signals: Main menu /Test /Function status /Communication /
