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

CAUTION

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to

serious consequences. Observe the precautions of both levels because they are important for personal and system safety. Make sure that the end users read this manual and then keep the manual in a safe place for future reference.

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.

[Design Precautions]

WARNING

Do not write any data to the "system area" of the buffer memory in the intelligent function module. Also, do not use any "use prohibited" signals as an output signal from the programmable controller CPU to the intelligent function module. Doing so may cause malfunction of the programmable controller system.

CAUTION

Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm (3.94 inches) or more between them. Failure to do so may result in malfunction due to noise.

A - 1

[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. Incorrect mounting may cause malfunction, failure or drop of the module. Fix the module to the base unit with a fixing bracket. (Q68TD-G-H02 only) When using the programmable controller in an environment of frequent vibrations, fix the module with a module fixing screw. (Q68TD-G-H01 only) Tighten the screw within the specified torque range. Undertightening can cause drop of the screw, short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may result in damage to the product. A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module supporting the online module change function is used. Note that there are restrictions on the modules that can be replaced online, and each module has its predetermined replacement procedure. For details, refer to the relevant chapter in this manual.

Do not directly touch any conductive parts and electronic components of the module. Doing so can cause malfunction or failure of the module.

[Wiring Precautions]

CAUTION

Individually ground the shielded cables of the programmable controller with a ground resistance of

Ω or less. Failure to do so may result in electric shock or malfunction.

100

Connectors for external devices must be crimped or pressed with the tool specified by the manufacturer, or must be correctly soldered. Incomplete connections may cause short circuit, fire, or malfunction.

Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.

A - 2

[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.

When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable with connector, hold the connector part of the cable. Pulling the cable connected to the module may result in malfunction or damage to the module or cable.

Keep a distance of 100mm (3.94 inches) or more between a thermocouple and the main circuit line or AC control lines. Also, keep the thermocouple away from a circuit that includes harmonics, such as a high-voltage circuit and a load circuit of an inverter.

Do not place the module near a device that generates magnetic noise.

A - 3

[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. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

CAUTION

Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.

Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may cause the module to fail or malfunction. A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module supporting the online module change function is used. Note that there are restrictions on the modules that can be replaced online, and each module has its predetermined replacement procedure. For details, refer to the relevant chapter in this manual.

After the first use of the product, do not mount/remove the module to/from the base unit more than 50 times (IEC 61131-2 compliant). Exceeding the limit of 50 times may cause malfunction.

Before handling the module, touch a grounded metal object to discharge the static electricity from the human body. Failure to do so may cause the module to fail or malfunction.

[Disposal Precautions]

CAUTION

When disposing of this product, treat it as industrial waste.

OVERVIEW

1.1 Features

(1) Channels isolated

Q68TD-G-H02(H01) is channel isolated modules.

(2) 8 channels of temperatures measured by one module

One Q68TD-G-H02(H01) module can measure temperatures of 8 channels. It can also convert the detected temperature values into scaling values (ratios (%)).

(3) Setting of conversion enable/disable

Conversion enable/disable setting for each channel is possible. Disabling conversion for unused channels prevents unnecessary disconnection detection or monitor of disconnection state on unused channels.

(4) Use of thermocouples conforming to JIS or IEC standards

Eight types of thermocouple (K, E, J, T, B, R, S, N) conforming to JIS or IEC standards can be used. A thermocouple type can be selected for each channel.

(5) Disconnection detection function (Q68TD-G-H02 only)

Disconnection status of thermocouple or compensating lead wire can be detected for each channel by Disconnection detection flag. Disconnection status can also be detected from the measured temperature value by setting "Up scale", "Down scale" or "Given value" for the Conversion setting for disconnection detection.

(6) Disconnection monitor function (Q68TD-G-H01 only)

Disconnection status of thermocouple or compensating lead wire can be checked on each channel by Disconnection state monitor flag. Disconnection status can also be checked from the measured temperature value by setting "Up scale", "Down scale" or "Given value" for the Conversion setting for disconnection detection.

(7) Selection of sampling processing, time average processing, count

average processing, moving average processing, and primary delay filter

As a conversion processing method, sampling processing, time average processing, count average processing, moving average or primary delay filter can be selected for each channel.

1 - 2

(8) Cold junction temperature compensation by cold junction temperature

compensation resistor (RTD)

Cold junction temperature compensation is possible by connecting the supplied cold junction temperature compensation resistor (RTD) and enabling the cold junction temperature compensation. Resistance temperature detector Pt100 is used for cold junction temperature compensation resistor (RTD).

1.1 Features

OVERVIEW

(9) Error compensation by offset/gain value setting

Error compensation can be made by setting offset and gain values on each channel. As the offset and gain values, you can make selection from user range setting and factory default setting.

(10)Warning output function

(a) Process alarm warning output

(b) Rate alarm warning output

A warning can be output when the input range set by the user is exceeded. Upper limit value and lower limit value can be set for each channel, and a setting to have a difference (hysteresis) between warning output and warning clear is also possible.

By setting a changing rate, a warning can be output when the changing rate is exceeded.

OVERVIEW

SYSTEM

CONFIGURATION

(11)Online module change

The module can be changed without stopping the system. Furthermore, the following operations can be processed by using sequence programs.

• Transferring the offset/gain set values to the replacement Q68TD-G-H02 (H01)

• Transferring the offset/and gain set values to another Q68TD-G-H02 (H01) mounted on the other slot

(12)Easy settings using GX Configurator-TI

Using GX Configurator-TI which is sold separately, sequence programs can be reduced since settings of the Q68TD-G-H02 (H01) can be made on the screen. Also, the set status or operating status of the module can be checked easily.

* 1 To satisfy with the accuracy, a warm-up (power distribution) period of 30 minutes is required. * 2 Calculate the accuracy in the following method.

(Accuracy) = (conversion accuracy) + (temperature characteristic) (operating ambient temperature variation) + (cold junction temperature compensation accuracy) An operating ambient temperature variation indicates a deviation of the operating ambient

temperature from the 25 5 range. Example: When using the thermocouple B (refer to Section 3.1 (2)) with the operating ambient

temperature of 35 and the measured temperature of 1000 , the accuracy is as follows.

( 2.5 )+( 0.4 )(35-30 )+( 1 )= 5.5

* 3 The conversion speed indicates the maximum time from when the input temperature changes till

when the measured temperature value of buffer memory is batch-updated.

* 4 The sampling period indicates the period batch-updating the measured temperature value in one

channel.

* 5 When disconnection state is detected, output values are selected from "Up scale", "Down scale" or

Given scale". (Refer to Section 3.2.2)

* 6 The Q68TD-G-H01 does not have the disconnection detection function. However, the

disconnection monitor function is available to select a measured temperature value on a disconnection occurrence from either "Up scale", "Down scale", or "Given value". (Refer to Section

3.2.3) It takes up to 11s to check a disconnection state.
