Example of X130 (RTD) analog input deadband supervisionTemperature sensor Pt100 is used in the temperature range of 15...180 °C. Valueunit “Degrees Celsius” is used and the set values Value minimum and Valuemaximum are set to 15 and 180, respectively.Value deadband = 7500 (7,5% of the total measuring range 165)AI_VAL# = AI_DB# = 85If AI_VAL# changes to 90, the reporting delay is:t s s( ) ( ) /% ,= − ×− × ≈180 15 7500 100090 85 100 2 5GUID-F47EF6B6-9A14-44A2-AD19-BC067E4A7D78 V1 EN (Equation )Table 53:Settings for X130 (RTD) analog input deadband supervisionFunction Setting Maximum/minimum (=range)X130 (RTD) analog input Value deadband Value maximum / Value minimum(=20000)Since the function can be utilized in various measurement modes,the default values are set to the extremes; thus, it is very importantto set correct limit values to suit the application before thedeadband supervision works properly.3.11.2.9 RTD temperature vs. resistanceTable 54:Temperature vs. resistanceTemp°CPlatinum TCR 0.00385 Nickel TCR 0.00618 Copper TCR0.00427Pt 100 Pt 250 Ni 100 Ni 120 Ni 250 Cu 10-40 84.27 210.675 79.1 94.92 197.75 7.49-30 88.22 220.55 84.1 100.92 210.25 --20 92.16 230.4 89.3 107.16 223.25 8.263-10 96.09 240.225 94.6 113.52 236.5 -0 100 250 100 120 250 9.03510 103.9 259.75 105.6 126.72 264 -20 107.79 269.475 111.2 133.44 278 9.80730 111.67 279.175 117.1 140.52 292.75 -40 115.54 288.85 123 147.6 307.5 10.5850 119.4 298.5 129.1 154.92 322.75 -60 123.24 308.1 135.3 162.36 338.25 11.35270 127.07 317.675 141.7 170.04 354.25 -Table continues on next page1YHT530004D05 D Section 3Basic functions615 series 91Technical Manual
