SAFETY PRECAUTIONS

(Read these precautions before use.)

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. When using the programmable controller in an environment of frequent vibrations, fix the module with a screw. 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.

A - 2

[Wiring Precautions]

CAUTION

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

Ω or less.

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

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 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.

A - 3

[Wiring Precautions]

CAUTION

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.

[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.

A - 4

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.

Do not touch any terminal while power is on. Failure to do so may cause malfunction.

Shut off the external power supply (all phases) used in the system before cleaning the module or retightening the module fixing screws. Failure to do so may 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.

OVERVIEW

1.1 Features

(1) Isolated channels

The Q68RD3-G is a channel isolated module.

(2) Temperature measurement of eight channels available in one module

The Q68RD3-G can measure temperature of eight channels in one module. The module can also convert the detected measured temperature values into scaling values (ratios (%)).

(3) Conversion enable/disable setting

Conversion enable/disable setting is possible for each channel. Disabling conversion for unused channels prevents unnecessary disconnection detection.

(4) Use of 3-wire RTDs conforming to standards

3-wire RTDs listed in the table below can be used.

Also, RTD type and measurement range can be set for each channel using GX Developer.

(5) Disconnection detection

Disconnection status of RTD 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) Selection of sampling processing, time average processing, count

average processing, moving average processing, and primary delay filter

A temperature conversion system: sampling processing, time average processing, count average processing, moving average or primary delay filter can be selected for each channel.

(7) Error compensation by offset/gain value setting

Error compensation is available by setting offset/gain values for each channel. Offset/gain values can be selected from user range setting and factory default setting.

(8) Warning output function

(a) Process alarm warning output

A warning can be output when the measured temperature value exceeds the input range set by user. 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 available.

(b) Rate alarm warning output

A warning can be output when the measured temperature value exceeds the rate of temperature change set by user.

(9) 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 Q68RD3-G

• Transferring the offset/and gain set values to another Q68RD3-G mounted on the other slot

(10)Easy settings using GX Configurator-TI

Using GX Configurator-TI which is sold separately, sequence programs can be reduced since settings of the Q68RD3-G can be made on the screen. Also, the set status or operating status of the module can be checked easily.

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

(1) Measured temperature values within the scaling range set in the CH

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

(Un\G78 to Un\G93), and the result is stored.

(2) 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

[Example] To scale a temperature to percent

When the CH1 measured temperature value of 360 (measured temperature value =

3600) is scaled at the following settings:

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)

Scaling value =

(100 - 0)

3600 - (-1000)

5000 - (-1000)

+ 0 =

76.666666

= 77[%]

Fractional portion is rounded off.

Stores into buffer memory address 50.

+ scaling width lower limit value

POINT

(1) If the upper limit value is less than the lower limit value in the settings of the

CH Scaling range upper/lower limit values (Un\G62 to Un\G77) or the CH Scaling width upper/lower limit values (Un\G78 to Un\G93), it will not result in an error and the scaling value calculated with the expression above will be output.

(2) When the measured temperature is out of the range set in the Scaling range

upper/lower limit values, the value set in the Scaling width upper limit value or lower limit value is stored into this buffer memory.

This section describes 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 configuring a highly-reliable system and making full use of the capabilities of Q68RD3-G. Precautions for external wiring are described below.

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

signals of the Q68RD3-G to avoid the influence of the AC side surges and inductions.

(2) Always place a RTD at least 100mm (3.94 inch) 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.

4.6 Offset/Gain Setting

PROCEDURES AND SETTINGS BEFORE SYSTEM OPERATION

POINT

(1) Perform offset/gain setting in the actual operating status. (2) Offset/gain values are stored in the Flash memory of the Q68RD3-G by

turning ON User range write request (YA). These values are not erased even at power-off. To prevent unnecessary write to the Flash memory, an error (error code: 162) occurs when values are written 26 times continuously.

(3) Set the offset/gain values within the range where the following conditions are

satisfied.

(Gain value) - (Offset value) > 0.1[ ] Set the offset/gain temperature setting values within the range where the following conditions are satisfied.

(Gain temperature setting value) - (Offset temperature setting value) > 0.1[ ]

(4) When User range write request (YA) is turned ON, consistency checks, for

offset value and gain value, and for offset temperature setting value and gain temperature setting value, are executed. If an error occurs on any channel, offset/gain values are not written to the module. Check the value in the Error code (Un\G19) and take a corrective action. Then, perform offset/gain setting again.

(5) Offset/gain setting can be performed on multiple channels at the same time.

However, set the offset/gain channels separately. If the offset/gain channels are set at the same time, an error (error code: 500) occurs.

(6) It takes approximately 7 seconds before Channel change completion flag

(XB) turns ON after turning ON Channel change request (YB). During this period, input to channels targeted for offset/gain setting must be constant. In addition, if disconnection state is detected during this period, Channel

change completion flag (XB) turns ON earlier and an error (error code: 51 ) occurs at the same time. If this occurs, perform offset/gain setting again after connection is restored.

(7) If an error (error code: 51 ) described at (6) occurs while performing offset/

gain setting simultaneously on multiple channels, values are not set only for the disconnected channel but also normally-connected channels. Therefore, perform offset/gain setting again for all adjusting target channels after connection is restored.

(8) Module ready (X0) turns from OFF to ON when the offset/gain setting mode is

switched to the normal mode by the dedicated instruction (G(P).OFFGAN) or the setting in the Mode switching setting (Un\G158 and Un\G159). Note that initial setting processing will be executed if there is a sequence program that performs initial settings when Module ready (X0) turns ON.
