Page 6 Doing so may occasionally result in minor injury due to electric shock. Do not touch the terminals or the electronic components or pat- terns on the PCB within 1 minute after turning OFF the power sup- ply. Doing so may occasionally result in minor injury due to electric shock.
Page 7: Precautions For Safe Use
Digital Controllers are mounted closely side by side or one on top of the other. If this type of mounting is used, use forced cooling, e.g., use a fan to blow air onto the Digital Controllers.
Page 8: Precautions For Correct Use
To prevent inductive noise, separate the wiring for the product's terminal block and connector from high-voltage, high-current power lines. Do not run the wiring parallel to or in the same cable as power lines. The influence of noise can also be reduced by using separate wiring ducts or shield lines.

When performing communications with a host computer, a unit number must be set for each Controller to allow the host computer to recognize it. Any number from 0 to 99 can be set. The unit number is set to 1 by default. When using multiple Controllers, make sure that no Controllers have the same unit number or communica- tions will not take place correctly.

• Calibration is ended by turning OFF the power. • The parameters for input calibration are shown below. (The last digit of Display No. 1 shows the input number. The example below shows 1 for input 1. For input 2, the display would show p390.2.) (Aging Timer) Input Type (See note.)
Page 344 9.1 Parameters for User Calibration If user calibration was performed on any of inputs 1 to 4 or outputs 1 to 6 following purchase of the Controller, user calibration information will be displayed as shown below when you move to Calibration Level.
Page 345: User Calibration
Section 9 User Calibration 9.2 User Calibration The E5AR-T/ER-T is calibrated before shipment from the factory and thus there is normally no need for the user to perform calibration. If user calibration is necessary, use the calibration functions for temperature inputs, analog inputs, and outputs that are provided in the Controller.
Page 346: Thermocouple Input Calibration
• Thermocouples are calibrated in two groups according to thermocouple type: Group 1 (input types 2, 4, 7, 8, 10, 14) and Group 2 (input types 3, 5, 6, 9, 11, 12, 13). • Do not obstruct the bottom of the Controller during calibration. Also, do not touch the input terminals or compensating leads.

Page 348 9. Wait until the count on Display No. 2 is sufficiently stable and then press the D Key. This tentatively registers the calibration data at this point. 10. Press the M Key. The display at the left will appear. This display will not str.i1 appear if all of the required data has not been tentatively registered.

Page 355: Inspecting Indicator Accuracy
• After calibrating an input, always inspect the indicator accuracy to verify that the input was calibrated correctly. • Operate the E5AR-T/ER-T in the PV/SP state. • Check the indicator at three points: the upper limit, lower limit, and mid-range limit of the indicator range. ■ Thermocouples ● Preparations Connect the required devices as shown below.
