Applying Settings

The relay settings for the particular application must be applied before any secondary testing occurs. If relay
settings are not available, then the relay with default settings can be used for precommissioning tests.
Note that the tripping and alarm contacts for any function must be programmed correctly before any scheme
tests are carried out.
The relay features multiple settings groups. Only one of the settings groups is active at a time. In the applica-
tions where more than one settings group is to be used, it can be necessary to test the relay in more than one
configuration.
When using the settings groups, it is not important for the relay to operate in the settings apart from the
current display mode. The relay operates in the Active Settings Group and the visible edit/view settings group
can be altered. This allows the settings in one group to be altered from the relay fascia while the protection
continues to operate on a different unaffected group. The Active Settings Group and the Edit Settings Group
are selected in the Menu.
If the relay is allowed to trip during testing, the instruments display is interrupted and replaced by the Trip
Alert screen which displays the fault-data information.
After applying a settings change to the relay, which may involve a change to the indication and output
contacts, press the TEST/RESET▶ key to ensure that any existing indication and output is correctly cleared.
