Completing The Test - ABB RET670 Commissioning Manual

1MRK 504 154-UUS B
1. Repeat the above test steps 1 to 2.
2. Set
their rated value till 1 minute.
3. Check the MAXPAFD and MAXPRFD outputs after 1 minute and compare it with last 1 minute
average power values.
4. Increase either three phase current or voltage above the last 1 minute value.
5. After 1 minute check the MAXPAFD and MAXPRFD whether it is showing the last 1 minute
average power value as maximum.
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
their rated value till 1 minute.
3. Ensure that the active and reactive energy values are less than the
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
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.

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.
10.15 Station communication
10.15.1 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.
