carefully and pay full attention to safety to handle the product correctly.

The instructions given in this manual are concerned with this product. For the safety instructions of the

programmable controller system, please read the CPU module user's manual.

In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".

Note that the CAUTION level may lead to a serious consequence according to the circumstances.

Always follow the instructions of both levels because they are important to personal safety.

Please keep this manual in a safe place for future reference and also pass this manual on to the end user.

[Design Precautions]

DANGER

Provide a safety circuit outside the C Controller module to ensure that the entire system will operate

safely even if an external power failure or C Controller module failure occurs.

Failure to do so could result in accidents due to erroneous output or operation.

(1) For an emergency stop circuit, protection circuit and interlock circuit that is designed for

incompatible actions such as forward/reverse rotation or for damage prevention such as the

upper/lower limit setting in positioning, any of them must be provided outside the C Controller

module.

(2) When the C Controller module detects the following conditions, it will disable the output (Y) from

the user program and writing to buffer memory in the case of both (a) and (b) and turn off all

outputs for (b).

Whether to hold or clear all the outputs is set by a parameter.

(a) The overcurrent protector or overvoltage protector of the power supply module is activated.

(b) An error such as a watchdog timer error is detected by the self-diagnostic function of the C

Controller module.

If an error occurs in I/O control parts and the C Controller module cannot detect the error, all the

outputs may turn ON.

Provide a fail-safe circuit or a preventive mechanism outside the C Controller module so that

machines will operate safely in such a case. For fail-safe circuit examples, refer to "Chapter 5

SETTINGS AND PROCEDURES BEFORE OPERATION" in this manual.

(3) Output could be left on or off when there is a fault in an output module relay or transistor.

So build an external monitoring circuit that will monitor any output signal that could cause serious

accidents.

DANGER Indicates that incorrect handling may cause hazardous conditions,

resulting in death or severe injury.

CAUTION Indicates that incorrect handling may cause hazardous conditions,

resulting in minor or moderate personal injury or physical damage.

A- 2

[Design Precautions]

DANGER

If load current more than the rating or overcurrent due to a short circuit in the load has flowed in the

output module for a long time, it may cause a fire and smoke. Provide an external safety device

such as a fuse.

Create the circuit so that the external power supply will turn on after the C Controller system is

powered on.

Turning on the external power supply first could result in accidents due to erroneous output or

operation.

For each station's operating status in the event of a each station error, refer to the corresponding

each station manual.

Not doing so could result in erroneous output or operation.

When controlling a running C Controller module (data modification) by connecting a personal

computer to the C Controller module, create an interlock circuit on user programs so that the whole

system functions safely all the time.

This must be also done when performing any other controls (e.g. operating status change (status

control)) or operations instructed from the computer.

In these controls, especially the one performed from an external device to a C Controller module in a

remote location, some C Controller side problem may not be resolved immediately due to failure of

data communications.

To prevent this, create an interlock circuit on user programs and establish corrective procedures for

communication failure between the external device and the C Controller module.

When setting up the system, do not allow any empty slot on the base unit.

If any slot is left empty, be sure to use a blank cover (QG60).

Otherwise, in the short circuit test or when an overcurrent or overvoltage is accidentally applied to

the external I/O section, internal parts of the module may be flied.

CAUTION

Do not install the control wires or communication cables together with the main circuit or power

wires, or bring them close to each other.

Keep a distance of 100 mm (3.94 inch) or more between them.

Not doing so could result in malfunctions due to noise.

When controlling a lamp, heater or solenoid valve using an output module, large current

(approximately ten times greater than in normal conditions) may flow when the output is turned ON

from OFF.

Take preventive measures such as replacing the module with the one having sufficient rated current.

A- 3

[Installation Precautions]

CAUTION

Use the C Controller module in an environment that meets the general specifications shown in this

manual.

Using this C Controller module in an environment outside the range of the general specifications

could result in an electric shock, fire, erroneous operation, and damage to or deterioration of the

product.

While pressing the installation lever located at the bottom of module, insert the module fixing tab into

the fixing hole in the base unit until it stops. Then, mount the module with the fixing hole as a

supporting point.

Incorrect loading of the module can cause a malfunction, failure or drop.

When using the C Controller module in the environment of frequent vibrations, tighten the module

with screws.

Tighten the screws in the specified torque range.

Undertightening can cause a drop, short circuit or malfunction.

Overtightening can cause a drop, short circuit or malfunction due to damage to the screw or module.

Connect extension cables to the connectors of the base unit and the extension module correctly.

After connection, check them for looseness.

Poor contact could cause an input or output failure.

Be sure to set the CompactFlashTM card by pressing it into the CompactFlashTM card slot.

Confirm it is completely set.

Poor contact may lead to malfunctions.

Completely turn off the externally supplied power used in the system before mounting or removing

the module.

Not doing so could result in damage to the product.

Do not directly touch the module's conductive parts.

Doing so could cause an operation failure or give damage to the module.

A- 4

[Wiring Precautions]

DANGER

Completely turn off the externally supplied power used in the system when wiring.

Failure to do so could result in an electric shock or damage to the product.

Before energizing or operating the system after wiring, be sure attach the terminal cover supplied

with the product.

Failure to do so could result in an electric shock.

CAUTION

Be sure to ground the FG and LG terminals to the protective ground conductor.

Not doing so could result in an electric shock or erroneous operation.

Prevent foreign matter such as dust or wiring debris from entering the module.

Failure to do so could cause fires, damage, or erroneous operation.

When wiring, check the rated voltage and terminal layout.

Connecting a power supply of a different voltage rating or incorrect wiring may result in a fire or

failure.

Connect the Ethernet and/or RS-232 cables to the corresponding connectors of the C Controller

module properly.

Tighten the terminal screws with the specified torque.

If the terminal screws are loose, it could result in short circuits, fire or erroneous operation.

Tightening them too much may cause damages to the screws and/or the module, resulting in fallout,

short circuits or malfunction.

Be sure to place the communication and power cables into a duct or fasten them using clamps.

Failure to do so may damage the module or cables by pulling a dangling cable inadvertently or cause

the module to malfunction due to poor contact.

When disconnecting the communication and power cables from the module, do not pull a cable part

by hand.

For a cable with connectors, hold the connector by hand and disconnect it from the module.

Loosen screws on the part connected to the module before disconnecting a cable.

Pulling a cable that is still connected to the module may cause a malfunction or damage the module

or the cable.

Do not connect the outputs of multiple power supply modules in parallel.

Doing so can heat the power supply modules, causing fires or failures.

Crimp, pressure weld, or solder external connectors properly with the tools specified by the maker.

Refer to the I/O Module User's Manual for the tools.

Incomplete connection can cause a short circuit, fire or failure.

Doing so may cause an electric shock.

Correctly connect the battery.

Also, do not charge, disassemble, heat, place in fire, short circuit, or solder the battery.

Mishandling of the battery can cause overheating or cracks which could result in injury and/or fires.

Be sure to shut off all phases of the external power supply before retightening the terminal screws

and module fixing screws or cleaning.

Failure to do so may result in an electric shock.

If a terminal screw is loose, it may cause a short circuit or malfunction.

If too tight, it may cause damage to the screws and/or module, resulting in an accidental drop of the

module, short circuit or malfunctions.

When controlling a running C Controller module (data modification) by connecting a personal

computer to the C Controller module, create an interlock circuit on user programs so that the whole

system functions safely all the time.

This must be also done when performing any other controls (e.g. operating status change (status

control)) or operations instructed from the computer.

In these controls, especially the one performed from an external device to a C Controller module in a

remote location, some C Controller side problem may not be resolved immediately due to failure of
