Trip Relay Assign
The 825-P allows mapping of only protection trip elements to the Trip output relay.
Settings are presented as bit-enumerated strings. The second line of the display
identifies a given bit’s associated function. To assign a function to the Trip relay,
simply program a value “1” in the bit location for each element you desire to assign
using the TRIP A through TRIP D settings. The front panel display appears as
follows:
TRIPA=10110000

Make sure the Trip relay terminals (95, 96 and 98) are
labeled to correspond with the relay behavior setting
(Fail-Safe or Non-Fail-Safe).
