5. Increase the supply currents or voltage in next 1 minute cycle such that the active or reactive
energy values are greater than the
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.
11.14.2.2 Completing the test
continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
11.15 Station communication
11.15.1 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.
11.16 Remote communication
11.16.1 Binary signal transfer
Prepare the IED for verification of settings as outlined in section
settings".
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
Line distance protection REL670
