SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION". WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
[Installation Precautions] CAUTION Use the programmable controller in an environment that meets the general specifications in the user's manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product. To mount the module, while pressing the module mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place.
[Wiring Precautions] CAUTION A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before system operation. Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor contact.
[Startup and Maintenance Precautions] WARNING Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. Shut off the external power supply (all phases) used in the system before cleaning the module or retightening the terminal screws, connector screws, or module fixing screws. Failure to do so may result in electric shock or cause the module to fail or malfunction. Undertightening can cause drop of the screw, short circuit or malfunction.

4 4.6 SETUP AND PROCEDURES BEFORE OPERATION Offset/Gain Setting Execute offset/gain settings in the following procedure. When the factory shipped setting is used, offset/gain setting is not necessary. If the utility package is installed, execute the offset/gain setting according to the procedure in Section 5.6.2. (1) Setting procedure START With the intelligent function module swich setting, set the input type setting value to a type for executing error compensation.
SETUP AND PROCEDURES BEFORE OPERATION * 1 When inputting a value using such as a standard DC voltage generator, or using without cold junction temperature compensation on actual use, set it to "without cold junction compensation". * 2 The mode switching (normal mode to offset/gain setting mode to normal mode) method is indicated below. Table 4.5 Mode switching method Mode switching method Refer to (2)(a) in this Dedicated instruction (G(P).
4 SETUP AND PROCEDURES BEFORE OPERATION POINT (1) Execute the offset/gain settings in the actual operating status. (2) Offset value and gain value are stored in the Flash memory of the Q68TD-GH02(H01) by turning ON the user range write request (YA), and the values are not erased at power-off. To prevent unnecessary write to Flash memory, an error (error code 162) occures if writing is performed 26 times continuously.
SETUP AND PROCEDURES BEFORE OPERATION 1 (a) The program in dotted area of (a) is common to (a),(b) and (c). In this example, the I/O numbers for the Q68TD-G-H02(H01) are X/Y0 to X/YF. Table 4.
4 SETUP AND PROCEDURES BEFORE OPERATION (a) When switching the mode using dedicated instruction (G(P).OFFGAN) The following program example is for switching to the offset/gain setting mode with the dedicated instruction (G(P).OFFGAN) and changing the channel for the offset/gain setting, then writing the offset/gain values to the Q68TD-G-H02(H01) and then switching to the normal mode. Dedicated instruction (G.OFFGAN) *1 Stores offset/gain setting target channel. Copies data of D1 into D2.
