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=1

0110000

TIP

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).
