Set the inputtype that matches the sensor that is used. In the product specifications, thereare models with thermocouple/resistance thermometer inputs (multi-input)and models with analog input. The settings differ depending on the model.Check to make sure which model you are using.3-2-1Input TypeThe following example shows how to set a K thermocouple for −20.0 to500.0°C.Operating Procedure1. Press the O key for at least three seconds to move from the operationlevel to the initial setting level.Operation LevelC250Initial Setting Levelin-tInput type2. Press the U key to enter the set value of the desired sensor.When you use a K thermocouple (−20.0 to 500.0°C), enter 6 as the setvalue.5in-t636Hint: The key operation is fixed two seconds after the change, or by pressing the O or M key.Section 3-2Setting the Input TypeList of Input TypesInput typeControllers Platinum resistancewith Therthermometermocouple/ResistanceThermometer MultiinputThermocoupleSpecifications Set valuePt100012−199.9 to 500.0 (°C)/−199.9 to 900.0 (°F)0.0 to 100.0 (°C)/0.0 to 210.0 (°F)JPt10034−199.9 to 500.0 (°C)/−199.9 to 900.0 (°F)0.0 to 100.0 (°C)/0.0 to 210.0 (°F)K56−200 to 1,300 (°C)/−300 to 2,300 (°F)−20.0 to 500.0 (°C)/0.0 to 900.0 (°F)J78−100 to 850 (°C)/−100 to 1,500 (°F)−20.0 to 400.0 (°C)/0.0 to 750.0 (°F)T910−200 to 400 (°C)/−300 to 700 (°F)−199.9 to 400.0 (°C)/−199.9 to 700.0 (°F)EL11120 to 600 (°C)/0 to 1,100 (°F)−100 to 850 (°C)/−100 to 1,500 (°F)U1314−200 to 400 (°C)/−300 to 700 (°F)−199.9 to 400.0 (°C)/−199.9 to 700.0 (°F)NR1516−200 to 1,300 (°C)/−300 to 2,300 (°F)0 to 1,700 (°C)/0 to 3,000 (°F)SB17180 to 1,700 (°C)/0 to 3,000 (°F)100 to 1,800 (°C)/300 to 3,200 (°F)19200 to 90 (°C)/0 to 190 (°F)0 to 120 (°C)/0 to 240 (°F)115 to 165°C140 to 260°C21220 to 165 (°C)/0 to 320 (°F)0 to 260 (°C)/0 to 500 (°F)0 to 50 mV23Either of the following ranges, by scaling:−1,999 to 9,999−199.9 to 999.9Infrared temperature 10 to 70°Csensor ES1B60 to 120°CAnalog inputInput temperature setting range−200 to 850 (°C)/−300 to 1,500 (°F)• The default is 5.• If a platinum resistance thermometer is mistakenly connected while a setting for other than a platinum resistance thermometer is in effect, S.ERRwill be displayed.

When this parameter is set to pid, 2-PID control is selected, and when set to onof, ON/OFFcontrol, is selected.
The default is onof.2-PID ControlPID control is set by AT (auto-tuning), ST (self-tuning), or manual setting.For PID control, set the PID constants in the “proportional band” (P), “integraltime” (I), and “derivative time” (D) parameters.ON/OFF Control3-53-5-1In ON/OFF control, the control output is turned ON when the process value islower than the current set point, and the control output is turned OFF whenthe process value is higher than the current set point (reverse operation).Setting Output SpecificationsControl Periodscpc-cpControl period(heat)Control period(cool)• Set the output periods (control periods).
Though a shorter period providesbetter control performance, it is recommended that the control period beset to 20 seconds or longer for a relay output to preserve the service lifeof the relay. After the settings have been made in the initial setup, readjustthe control period, as required, by means such as trial operation.• Set the control periods in the “control period (heat)” and “control period(cool)” parameters in the initial setting level.
The default is 20 seconds.• The “control period (cool)” parameter is used only for heating/cooling control.• When control output 1 is used as a current output, “control period (heat)”cannot be used.38Section 3-5Setting Output Specifications3-5-2Direct and Reverse Operation• “Direct operation” increases the manipulated variable whenever the process value increases. “Reverse operation” decreases the manipulatedvariable whenever the process value increases.orevManipulated variableManipulated variable100%100%0%0%LowSet ValuetemperatureHightemperatureDirect operationLowSet ValuetemperatureHightemperatureReverse operationFor example, when the process value (PV) is lower than the set point (SP)in a heating control system, the manipulated variable increases accordingto the difference between the PV and SP.
Accordingly, reverse operation isused in a heating control system. Direct operation is used in a cooling control system, in which the operation is the opposite of a heating control system.• Direct/reverse operation is set in the “direct/reverse operation” parameterin the initial setting level. The default is or-r (reverse operation).Operating ProcedureIn this example, the input type, temperature unit, direct/reverse operation, andcontrol period (heat) parameters are checked.Input type = s (K thermocouple)Temperature unit = c (°C)Direct/reverse operation = or-r (reverse operation)Control period (heat) = 20 (seconds)1.
