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

Table 3.3 Function list

This function allows temperature data to be imported by connecting a thermocouple.

Temperature data are 16-bit signed binary (-2700 to 18200) and stored into buffer memory. (1) Sampling processing

A temperature input value is converted one by one on each channel and a measured

temperature value is output after every conversion. Then the value is stored into buffer

memory.

(2) Averaging processing

This processing averages a measured temperature value for each channel and the

averaged value is stored into buffer memory.

Averaging processing contains three methods as described below. (a) Time average (b) Count average (c) Moving average

(3) Primary delay filter

Measured temperature values are smoothed by a preset time constant. This function specifies whether temperature conversion is enabled or disabled on each

channel.

This function sets the type of thermocouple on each channel. Section 4.5

This function checks the disconnection of the connected thermocouple on each conversion-

enabled channel.

This function is to select a value to be stored in the CH Measured temperature value

(Un\G11 to Un\G18) from "Up scale", "Down scale" or "Given scale" when disconnection is

detected.

This function checks the disconnection of the connected thermocouple on each conversion-

enabled channel.

This function is to select a value to be stored in the CH Measured temperature value

(Un\G11 to Un\G18) from "Up scale", "Down scale" or "Given scale" when disconnection is

detected. This function determines whether to use cold junction temperature compensation.

Use this function to measure temperature in higher accuracy than the cold junction

temperature compensation accuracy ( 1 ) by the cold junction temperature

compensation resistor (RTD) that is included with the Q68TD-G-H02 (H01).

The cold junction temperature compensation accuracy can be improved by disabling the

cold junction temperature compensation and providing a precision ice bath externally.

This function detects a disconnection of connected cold junction temperature compensation

resistor (RTD).

Process alarm

A warning is output when the measured temperature value is equal to or more than the

process alarm upper upper limit value, or equal to or less than the process alarm lower

lower limit value.

(2)

Rate alarm

A warning is output when the measured temperature value changes in a rate by which

the measured temperature value reaches the rate alarm upper limit value or more, or

the rate alarm lower limit value or less.

(a) Sampling period

The Q68TD-G-H02(H01) measures the temperature from CH1 to CH8 every 40ms per channel. The sampling period indicates the period (320ms) batch-updating the measured temperature value in one channel in the case of that the sampling processing is specified with the Averaging processing selection (Un\G24 and Un\G25). Regardless of the number of conversion-enabled channels, the measured temperature values are stored in the buffer memory every 320ms.

(b) Conversion speed

The conversion speed indicates the maximum time required before the measured temperature values are stored into the buffer memory. The following figure shows the timing of storing the measured temperature values of Q68TD-G-H02 and Q68TD-G-H01 respectively.

(3) Averaging processing

Averaging processing requires at least 2 times of conversion processing excluding the maximum and the minimum values. After the first averaging processing is completed, the corresponding bit for a channel where processing has been completed of the Conversion completion flag (Un\G10) turns ON (changes to "1").

(a) Time average

Conversion is executed for a period of set time, and the total value, which excludes the maximum and the minimum values, is averaged and stored in the buffer memory. The number of processing times within the set time is below.

Number of processing times (times) = set time sampling period (320ms)

Setting range of time average is 1280 to 5000ms.

If a value outside the setting range is set, an error (error code: 20 ) occurs.

[Example] When six channels, channels 1, 2, 3, 4, 5, 6, are enabled for conversion and the set time is 2000ms, measurement is executed for six times and the average value is output.

2000 320 =6.25 (times)...... Drop the fractional part

(b) Count average

Conversion is executed for a preset number of times, and the total value excluding the maximum and the minimum values is averaged and stored in the buffer memory. The processing time is below.

Processing time = set count

Setting range of count average is 4 to 500 times.

If a value outside the setting range is set, an error (error code: 30 ) occurs.

[Example] When six channels, channels 1, 2, 3, 4, 5, 6, are enabled for conversion and the count averaging is set to 5 times, the average value is output for every 1600(ms). 5

3.2.5 Cold junction temperature compensation resistor disconnection detection function

This function detects disconnection of cold junction compensation resistor (RTD). When a cold junction compensation resistor (RTD) connected with a relay terminal block is disconnected, an error (error code 800) occurs. Consequently, the Error flag (XF) turns on and the “ERR” LED blinks to notify the error.

(1) Condition for detecting disconnection of cold junction compensation

resistor (RTD)

Disconnection of the cold junction temperature compensation can be detected only when the switch setting 4 of the intelligent function modules is set to “with cold junction compensation”. The following shows the conditions in which the disconnection of the cold junction temperature compensation resistor (RTD) can be detected.

(2) Operation for detecting disconnection of cold junction compensation

resistor (RTD)

When disconnection of cold junction temperature compensation resistor (RTD) is detected, conversion for every conversion-enabled channel stops. The measured temperature value for cold junction temperature compensation resistor (RTD) disconnection remains the same as the measured value prior to the disconnection detection.

(3) Operation and processing for restoring disconnection of cold junction

compensation resistor (RTD)

Conversion processing does not restart even after the disconnection of the cold junction temperature compensation resistor (RTD) is restored. To restart the conversion processing, turn off the Error clear request (YF).

3.4.17 CH[ ] Scaling value (Un\G50 to Un\G57)

The result of scaling measured temperature values is stored.

(1) Data storage

Measured temperature values within the scaling range set in CH Scaling range upper/lower limit values (Un\G62 to Un\G77) are scaled to the scaling width set in

CH Scaling width upper/lower limit values (Un\G78 to Un\G93), and then the result is stored.

(2) How to calculate the scaling value.

The following is how to calculate the scaling value.

Scaling value =

(scaling width upper limit value - scaling width lower limit value)

measured temperature value - scaling range lower limit value

scaling range upper limit value - scaling range lower limit value

Figure 3.34 How to caluculate the scaling value

[Setting example] To scale a temperature to percent (for the use of thermocouple K)

(a) Setting value

• Scaling range: -100 to 500 (lower limit value = -1000, upper limit value = 5000)

• Scaling width: 0 to 100% (lower limit value = 0, upper limit value = 100)

(b) Input value

4.4 Wiring

The following explains the wiring precautions and module connection example.

4.4.1 Wiring precautions

External wiring that is less susceptible to noise is required as a condition of enabling a highly reliable system and making full use of the capabilities of the Q68TD-G-H02(H01).

(1) Use separate cables for the AC control circuit and the external input

signals of the Q68TD-G-H02(H01) to avoid the influence of the AC side surges and inductions.

(2) Always place the thermocouple at least 100mm away from the main

circuit cables and AC control circuit lines. Fully keep it away from highvoltage cables and circuits, which include high frequency waves, such as an inverter's load circuit. Not doing so will cause the module more susceptible to noises, surges and inductions.

(3) The following wiring is required for the product to comply with the EMC

and Low Voltage Directives.
