SAFETY PRECAUTIONS

(Read these precautions before using.)

When using Mitsubishi equipment, thoroughly read this manual and the

associated manuals introduced in this manual. Also pay careful attention to

safety and handle the module properly.

These SAFETY PRECAUTIONS classify the safety precautions into two

categories: “DANGER” and “CAUTION”.

DANGER

CAUTION

Procedures which may lead to a dangerous condition and

cause death or serious injury, if not carried out properly.

Procedures which may lead to a dangerous condition and

cause superficial to medium injury, or physical damage

only, if not carried out properly.

Depending on circumstances, procedures indicated by CAUTION may also

be linked to serious results.

In any case, it is important to follow the directions for usage.

Store this manual in a safe place so that you can take it out and read it

whenever necessary. Always forward it to the end user.

[DESIGN PRECAUTIONS]

DANGER

Do not write data into the "system area" of the buffer memory of intelligent

function modules. Also, do not use any "prohibited to use" signals as an

output signal to an intelligent function module from the PLC CPU.

Writing data into the "system area" or outputting a signal for "prohibited to

use" may cause a PLC system malfunction.

CAUTION

Do not bunch the control wires or communication cables with the main

circuit or power wires, or install them close to each other.

They should be installed 100 mm(3.94 inch) or more from each other.

Not doing so could result in noise that may cause malfunction.

A - 2

[INSTALLATION PRECAUTIONS]

CAUTION

Use the PLC in an environment that meets the general specifications

contained in the CPU user's manual.

Using this PLC in an environment outside the range of the general

specifications may cause electric shock, fire, malfunction, and damage to

or deterioration of the product.

When installing the module, securely insert the module fixing tabs into the

mounting holes of the base module while pressing the installation lever

located at the bottom of the module downward.

Improper installation may result in malfunction, breakdown or the module

coming loose and dropping. Securely fix the module with screws if it is

subject to vibration during use.

Tighten the screws within the range of specified torque.

If the screws are loose, it may cause the module to fallout, short circuits, or

malfunction.

If the screws are tightened too much, it may cause damage to the screw

and/or the module, resulting in fallout, short circuits or malfunction.

Switch all phases of the external power supply off when mounting or

removing the module.

Not ding so may cause electric shock or damage to the module.

Do not directly touch the conductive area or electronic components of the

module. Doing so may cause malfunction or failure in the module.

[WIRING PRECAUTIONS]

CAUTION

Always ground the FG terminal for the PLC.

There is a risk of electric shock or malfunction.

When turning on the power and operating the module after wiring is

completed, always attach the terminal cover that comes with the product.

There is a risk of electric shock if the terminal cover is not attached.

Tighten the terminal screws within the range of specified torque.

If the terminal screws are loose, it may result in short circuits or malfunction.If

the terminal screws are tightened too much, it may cause damage to the screw

and/or the module, resulting in short circuits or malfunction.

Be careful not to let foreign matter such as sawdust or wire chips get inside

the module.They may cause fires, failure or malfunction.

A - 3

[WIRING PRECAUTIONS]

CAUTION

The top surface of the module is covered with protective film to prevent

foreign objects such as cable offcuts from entering the module when wiring.

Do not remove this film until the wiring is complete.

Before operating the system, be sure to remove the film to provide

adequate ventilation.

Always place the thermocouple at least 100mm (3.94inch) away from the

main circuit cables and AC control lines. Fully keep it away from high-

voltage cables and circuits which include harmonics, such as an inverter's

load circuit. Not doing so will make the module more susceptible to noises,

surges and inductions.

*1: 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 5range.

Example: When the thermocouple used is B, the operating ambient temperature is 35 , and

the measured temperature is 1000 , the accuracy is:

( 2.5) + ( 0.4 ) (5 ) + ( 1) = 5.5

*2: The conversion speed is a period from when a temperature is input and converted into a

corresponding digital value until the value is stored into the buffer memory. When two or more

channels are used, the conversion speed is "40ms number of conversion enabled channels".

*3: At wire break detection, the temperature measurement value right before wire break occurrence is held.

*1: 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 5range.

Example: When the thermocouple used is B, the operating ambient temperature is 35 , and

the measured temperature is 1000 , the accuracy is:

( 3.5 ) + ( 0.4 ) (5 ) + ( 1) = 6.5

*2: A period until a thermocouple input value/micro voltage input value is converted into a temperature

measurement value/micro voltage conversion value.

*3: A period until a thermocouple input value/micro voltage input value is converted into a

temperature measurement value/micro voltage conversion value and the resultant value is stored

into the buffer memory.

The conversion speed is a delay time that occurs during sampling processing. It is independent of

averaging processing.

Example: When two channels are enabled for conversion

(Conversion speed) = (sampling period) 3

= (20ms 2 channels) 3

= 120ms
