The hysteresis is added to the extreme value of the rangelimit to allow the measurement slightly to exceed the limit value before it isconsidered as out of range.3.11.2.8 Deadband supervisionEach input has an independent deadband supervision. The deadband supervisionfunction reports the measured value according to integrated changes over a timeperiod.GUID-63CA9A0F-24D8-4BA8-A667-88632DF53284 V1 ENFigure 26: Integral deadband supervisionThe deadband value used in the integral calculation is configured with the Valuedeadband setting. The value represents the percentage of the difference betweenthe maximum and minimum limits in the units of 0.001 percent * seconds. Thereporting delay of the integral algorithms in seconds is calculated with the formula:t s Y( ) (= ×∆ ×Value maximum - Value minimum) deadband / 10001000%GUID-CC447162-C1B4-4E74-A253-828F388266EB V1 EN (Equation )Section 3 1YHT530004D05 DBasic functions90 615 seriesTechnical Manual
