4…3 BASIC CONFIGURATION LEVEL3.1 Set Up Input (Process Variable)Information.• Universal inputs – mV, mA, V, THC, RTD and resistance.• Internal cold junction compensation.• Linearization – of temperature sensors to allow use of non-linearizing transmitters or any electrical input.• Programmable fault levels and actions.• Digital filter – to reduces the effect of noise on inputs.Example A – setting up:• a current input of 4 to 20 mA• displaying a range of 0 to 200psi• a fault detection level 10% above 200psi (engineering/display range) and 10% below 0psi (engineering/display range)• in the event of a fault being detected and/or the fault detection level being exceeded the process variable is driven downscale.Example B – setting up:• a Type K thermocouple• displaying temperature in °F• displaying a range of 0 to 2000°F• a fault detection level 10% above 2000°F (engineering/display range) and 10% below 0°F (engineering/display range)• in the event of a fault being detected and/or the fault detection level being exceeded the process variable is driven upscale.InputTypeLinearizerType5/23/2√RTDTHC NTHC BTHC ETHC LTHC JTHC TTHC STHC RTHC KNoneTemp.
