3 Basic IED functions
3.1 Parameter setting groups (ACGR)
Prepare the IED for verification of settings as outlined in section 1 "Overview" and section 2
"Preparing for test" in this chapter.
3.1.1 Verifying the settings
Procedure
1. Check the configuration of binary inputs that control the selection of
the active setting group.
2. Browse the ‘ActiveGroup’ menu to achieve information about the ac-
tive setting group.
The ActiveGroup menu is located in the local HMI under:
Test\Function status\Setting groups
3. Connect the appropriate dc voltage to the corresponding binary in-
put of the IED and observe the information presented on the HMI dis-
play.
The displayed information must always correspond to the activated input.
4. Check that the corresponding output indicates the active group.
Operating procedures for the PC aided methods of changing the active
setting groups are described in the corresponding PCM documents and
instructions for the operators within the SCS are included in the SCS doc-
umentation.
3.1.2 Completing the test
Continue to test another function or end the test by changing the test mode setting to off.
