Themode will be changed to the calibration mode, and adj will be displayed.• The “move to calibration level” parameter may not be displayed when theuser is doing the calibration for the first time. If this happens, set the “initial/communications protect” parameter in the protect level to 0 beforemoving to the advanced function setting level.• The calibration mode is ended by turning the power OFF.• The parameter calibrations in the calibration mode are structured asshown below.Controllers with Thermocouple/Resistance Thermometer Multi-inputsAdvanced Function SettingLeveladjMoves automatically according to input type.30Platinum resistancethermometer0: Pt1001: Pt1002: Pt1003: JPt1004: JPt100Thermocouple or infraredtemperature sensor5: K7: J11: E12: L15: N19: K140F/60C20: K240F/120C21: K280F/140C22: K440F/220C23: 0 to 50 mVp390p280t 54t 24c 54p 10p 10t -6t -6t -6pb10pb10c 54pb 0pb 0c -6e20c454345444083e26b4543b9a5298845444083no020029be35b8stre220ba13bias1846: K8: J9, 10: T13, 14: U16: R17: S18: BAnalog inputbias35b8b9as2988Section 6-1Parameter StructureControllers with Analog InputsAdvanced FunctionSetting Leveladj30Moves automatically according to input type.Current inputVoltage input0: 4 to 20 mA1: 0 to 20 mA2: 1 to 5 V3: 0 to 5 V4: 0 to 10 Va 201v 52v10a1v 12v 1c8e7c7c314677sac0b1044ad9strnoWhen calibration has been performed after purchase, the user calibrationinformation shown in the following illustration will be displayed when moving tothe calibration level..adj30A dot is displayed.185Section 6-2User Calibration6-2User CalibrationThe E5CN/CN-U/AN/EN is correctly calibrated before it is shipped from thefactory, and normally need not be calibrated by the user.If, however, it must be calibrated by the user, use the parameters for calibrating temperature input and analog input.
OMRON, however, cannot ensure theresults of calibration by the user. Also, calibration data is overwritten with thelatest calibration results. The default calibration settings cannot be restoredafter user calibration. Perform user calibration with care.6-2-1Calibrating InputsThe input type selected in the parameter is used for calibration. The inputtypes are as follows:Controllers with Thermocouple/Resistance Thermometer Multi-inputs• Thermocouple:14 types• Infrared temperature sensor:4 types• Analog input:1 type• Platinum resistance thermometer: 5 typesControllers with Analog Inputs• Current input: 2 types• Voltage input: 3 types6-2-2Registering Calibration DataThe new calibration data for each item is temporarily registered.
It can be officially registered as calibration data only when all items have been calibratedto new values. Therefore, be sure to temporarily register all items when youperform the calibration. When the data is registered, it is also recorded thatuser calibration has been performed.Prepare separate measuring devices and equipment for calibration. Fordetails on how to handle measuring devices and equipment, refer to therespective instruction manuals.6-3Thermocouple Calibration (Thermocouple/ResistanceThermometer Input)• Calibrate according to the type of thermocouple: thermocouple 1 group(input types 5, 7, 11, 12, 15) and thermocouple 2 group (input types 6, 8,9, 10, 13, 14, 16, 17, 18, 19, 20, 21, 22).• When calibrating, do not cover the bottom of the Controller.
Also, do nottouch input terminals/pins (terminals 4 and 5 on the E5CN, pins 1 and 2on the E5CN-U, and pins 17 and 18 on the E5AN/EN) or compensatingconductors.186Section 6-3Thermocouple Calibration (Thermocouple/Resistance Thermometer Input)6-3-1PreparationsE5CN9Input power supply10STV−4Cold junctioncompensator+50°C/32°FCompensating conductorE5CN-U10Input power supply11STV−2Cold junctioncompensator+10°C/32°FCompensating conductor1E5AN/ENSTVInput power supply2− 17Cold junctioncompensator+ 180°C/32°FCompensating conductor• Set the cold junction compensator designed for compensation of internalthermocouples to 0°C.
Make sure that internal thermocouples are disabled (i.e., that tips are open).• In the above figure, STV indicates a standard DC current/voltage source.• Use the compensating conductor designed for the selected thermocouple. When thermocouples R, S, E, or B or an infrared temperature sensoris used, the cold junction compensator and the compensating conductorcan be substituted with the cold junction compensator and the compensating conductor for thermocouple K.■ Connecting the Cold Junction CompensatorCorrect process values cannot be obtained if you touch the contact ends ofthe compensating conductor during calibration of a thermocouple.
Accordingly, short-circuit (enable) or open (disable) the tip of the thermocouple insidethe cold junction compensator as shown in the figure below to create a contact or non-contact state for the cold junction compensator.Cold junction compensatorShort-circuitE5CNE5CN-UE5ANE5EN0°C/32°FCompensating conductorE5CNE5CN-UE5ANE5ENCold junction compensator0°C/32°FOpenCompensating conductor187Section 6-3Thermocouple Calibration (Thermocouple/Resistance Thermometer Input)In this example, calibration is shown for a Controller with a Thermocouple/Resistance Thermometer Multi-input, with thermocouple/infrared temperaturesensor set as the input type.1,2,3... 1.

Release the key andwait two seconds or press the M key.
This stores the temporarily registered calibration data to EEPROM. To cancel the saving of temporarilyregistered calibration data to EEPROM, press the M key (while no is displayed in the No. 2 display) without pressing the U key.13.
