6–12 489 GENERATOR MANAGEMENT RELAY – INSTRUCTION MANUAL
CHAPTER 6: ACTUAL VALUES
Note
The various trip pickup actual values reflect the Input Name as programmed in the first line
of the message. The various digital and analog input functions are shown only if the
function has been assigned as an input.
The trip pickup messages may be very useful during testing. They will indicate if a trip
feature has been enabled, if it is inactive (not picked up), timing out (picked up and timing),
active trip (still picked up, timed out, and causing a trip), or latched tip (no longer picked up,
but had timed out and caused a trip that is latched). These values may also be particularly
useful as data transmitted to a master device for monitoring.
