Travel Accumulator Alert—This alert is active if the Travel Accumulator exceeds the Travel Accumulator Alert Point.
The Travel Accumulator Alert is set when the Travel Accumulator value exceeds the Travel Accumulator Alert Point.
It is cleared after you reset the Travel Accumulation to a value less than the alert point.
Travel Accumulator Alert Enable—When enabled Travel Accumulator Alert Enable activates checking of the
difference between the Travel Accumulator value and the Travel Accumulator Alert Point.
Travel Accumulator Alert Point—Travel Accumulator Alert Point (TVL_ACCUM_ALRT_PT [77.4]) is the value of the
Travel Accumulator, in percent (%) of ranged travel, which, when exceeded, sets the Travel Accumulator Alert.
Travel Accumulator Deadband—Travel Accumulator Deadband (TVL_ACCUM_DB [77.5]) is the area around the
travel reference point, in percent (%) of ranged travel, that was established at the last increment of the
accumulator. This area must be exceeded before a change in travel can be accumulated. See figure 4‐5.
