Temperature Controller - Staveb AG

5-22 Parameter Functions and Definitionswithin the range defined by the upper and lower limit values in the Set PointUpper Limit and Set Point Lower Limit parameters. If an attempt is made toenter a SP value outside the upper or lower limit from the keypad the set pointdisplay will flash at the configured maximum upper- or lower-limit value.If the temperature input type or temperature units are changed, the set pointupper limit and set point lower limit are forcibly changed by the controller tothe upper and lower limits of the newly configured sensor.For a temperature input, the decimal point position is dependent on thecurrently selected sensor. For an analog input, it is dependent on the DecimalPoint parameter setting.Table 5.WParameter Configurable Range Units Default ValueSet PointUpper LimitSet PointLower LimitSet point lower limit +1 to sensor range EU 1300upper limitPlatinum resistance thermometer EU 850Sensor range lower limit to set pointupper limit –1EU –200Related ParametersInput Type (p. 5-20), °C/°F Selection (p. 5-21) (Initial Setting function group)PID/ON/OFFFunction: This parameter allows you to configure the controller for either the2-PID control or ON/OFF control method.The auto-tuning (AT) and self-tuning (ST) functions can only be used in the2-PID control method.Table 5.XSelectionspid: 2-PIDonof: ON/OFFDefault SelectiononofRelated Parameters• AT Execute/Cancel (p. 5-11), Manual Reset (p. 5-16), Hysteresis(OUT1) (p. 5-17) (Adjustment function group)• ST Stable Range (Advanced Setting function group) (p. 5-34)Publication 900-UM003C-EN-E - January 2004
