PXR3 Instruction Manual - Coulton Instrumentation

Input signal code (Setting range: 0 to 16)[Description]• This parameter is used for selecting input signals. Inputsignal varies depending on the sensors (2 types below).Set a code that corresponds to the sensor you use.Type I : Thermocouples (9 kinds of signals)Resistance bulbs (1 kind of signal)Type II : Voltage, current• Input signals can be selected within the same type. It isimpossible to select input signals of a different type.• For type II, when changing from the voltage input to thecurrent input, connect the supplied resistance of 250 Ωbetween terminals w and e .When changing from the current input to the voltage input,remove the resistance of 250 Ω connected to the inputterminals.[Note]After changing the codes, power off the PXR, and thenpower it on again.• Input signals and codesq Input signals code tableTypeInput signalResistance bulb (RTD)• Pt 100Thermocouple• J• K• RI • B• S• T• E• N• PL-IIII1 to 5 V, 4 to 20mA DCCode12345678121316[Setting example] Changing from thermocouple K to thermocouple T in Type IDisplayPV indicationSV indicationPV indication1.2.3.4.5.6.Press and hold the SEL key for three seconds.will be displayed.Press the key to display .Press the SEL key once.The current setting ( ) will be displayed.Operating procedurePress the or key to flicker and to display .Press the SEL key once. will be displayed and the thermocouple T will be registered for. After that, the controller will operate with the kind of input signals being thermocouple T.(Repeat the procedure from 3 to 5 to check the set value.)If you want to display the operation status, press and hold the SEL key for two seconds.The SV will be displayed on the display area.If unoperated state continues, the PV will be displayed.35
