Activating The Test Mode - ABB Relion 670 Series Commissioning Manual

1MRK 506 371-UUS E
Verify that analog input signals from the analog input module are measured and recorded
correctly by injecting currents and voltages required by the specific IED.
To make testing even more effective, use PCM600. PCM600 includes the Signal monitoring tool,
which is useful in reading the individual currents and voltages, their amplitudes and phase angles.
In addition, PCM600 contains the Disturbance handling tool. The content of reports generated by
the Disturbance handling tool can be configured which makes the work more efficient. For
example, the tool may be configured to only show time tagged events and to exclude analog
information and so on.
Check the disturbance report settings to ensure that the indications are correct.
For information about the functions to test, for example signal or parameter names, see the
technical manual. The correct initiation of the disturbance recorder is made on pickup and/or
release or trip from a function. Also check that the wanted recordings of analog (real and
calculated) and binary signals are achieved.
During testing, observe that the right testing method, that corresponds to the actual parameters
set in the activated parameter setting group, is used.
Set and configure the function(s) before testing. Most functions are highly flexible and permit a
choice of functional and tripping modes. The various modes are checked at the factory as part of
the design verification. In certain cases, only modes with a high probability of coming into
operation need to be checked when commissioned to verify the configuration and settings.

Activating the test mode

Put the IED into the test mode before testing. The test mode blocks all protection functions and
some of the control functions in the IED, and the individual functions to be tested can be
unblocked to prevent unwanted operation caused by other functions. In this way, it is possible to
test slower back-up measuring functions without the interference from faster measuring
functions. The test switch should then be connected to the IED.Test mode is indicated when the
yellow PickupLED flashes.
It is important that the IED function to be tested is put into test mode, even if the MU is sending
data marked as "test". The IED will interpret these data as valid if it is not in test mode.

Parameters can be entered into different setting groups. Make sure to test
functions for the same parameter setting group. If needed, repeat the tests for all
different setting groups used. The difference between testing the first parameter
setting group and the remaining is that there is no need for testing the
connections.
