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 ‘System
Configuration Menu’.
The currently Active Group and the group currently Viewed are shown at the top of the display in the Settings
display screen. If the View Group is not shown at the top of the display, this indicates that the setting is common
to all groups. CT/VT ratio, I/O mapping and other settings which are directly related to hardware are common to
all groups.
If the relay is allowed to trip during testing then the instruments display will be interrupted and replaced by the
‘Trip Alert’ screen which displays fault data information. If this normal operation interferes with testing then this
function can be temporarily disabled for the duration of testing by use of the Trip Alert Enabled/Disabled setting in
the System Config Menu.
After applying a settings change to the relay, which may involve a change to the indication and output contacts,
the
TEST/RESET
key should be pressed to ensure any existing indication and output is correctly cleared.
