The hysteresis is added to the extreme value of the range limit to allowthe measurement slightly to exceed the limit value before it is considered out of range.3.12.2.8 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 35: Integral deadband supervisionThe deadband value used in the integral calculation is configured with the Valuedeadband setting. The value represents the percentage of the difference between themaximum and minimum limits in the units of 0.001 percent * seconds. The reportingdelay of the integral algorithms in seconds is calculated with the formula:t s Y( )( )=− ⋅Value maximum Value minimum deadband s100000∆GUID-CC447162-C1B4-4E74-A253-828F388266EB V2 EN (Equation 3)1MRS758755 A Section 3Basic functionsREC615 and RER615 91Technical Manual
