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.

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

the programmable controller system, refer to the user’s manual for the CPU module used.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".

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.

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.

[Design Precautions]

WARNING

• Configure safety circuits external to the programmable controller to ensure that the entire system

operates safely even when a fault occurs in the external power supply or the programmable

controller. Failure to do so may result in an accident due to an incorrect output or malfunction.

(1) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and

protective interlock circuit for forward/reverse operation or upper/lower limit positioning.

(2) When the programmable controller detects an abnormal condition, it stops the operation and

all outputs are:

(a) Turned off if the overcurrent or overvoltage protection of the power supply module is

activated.

(b) Held or turned off according to the parameter setting if the self-diagnostic function of the

CPU module detects an error such as a watchdog timer error.

Note, however, that AnS series modules on the system turn off all outputs in both cases.

All outputs may turn on if an error occurs in a part, such as an I/O control part, where the

CPU module cannot detect any error. To ensure safety operation in such a case, provide a

safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-

safe circuit example, refer to the user’s manual for the CPU module used.

(3) Outputs may remain on or off due to a failure of an output module relay or transistor.

Configure an external circuit for monitoring output signals that could cause a serious

accident.

WARNING

CAUTION

A - 2 A - 2

[Design Precautions]

WARNING

• In an output module, when a load current exceeding the rated current or an overcurrent caused

by a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this,

configure an external safety circuit, such as a fuse.

• Configure a circuit so that the programmable controller is turned on first and then the external

power supply.

If the external power supply is turned on first, an accident may occur due to an incorrect output

or malfunction.

• For the operating status of each station after a communication failure, refer to relevant manuals

for each network.

Incorrect output or malfunction due to a communication failure may result in an accident.

• When changing data of the running programmable controller from a peripheral connected to the

CPU module or from a personal computer connected to an intelligent function module, configure

an interlock circuit in the sequence program to ensure that the entire system will always operate

safely.

For other controls to a running programmable controller (such as program modification or

operating status change), read relevant manuals carefully and ensure the safety before the

operation.

Especially, in the case of a control from an external device to a remote programmable controller,

immediate action cannot be taken for a problem on the programmable controller due to a

communication failure.

To prevent this, configure an interlock circuit in the sequence program, and determine corrective

actions to be taken between the external device and CPU module in case of a communication

failure.

CAUTION

• Do not install the control lines or communication cables together with the main circuit lines or

power cables.

Keep a distance of 100mm or more between them.

Failure to do so may result in malfunction due to noise.

• When a device such as a lamp, heater, or solenoid valve is controlled through an output module,

a large current (approximately ten times greater than normal) may flow when the output is

turned from off to on. Take measures such as replacing the module with one having a sufficient

current rating.

A - 3 A - 3

[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) in the hole(s) in the base unit and press the

module until it snaps into place.

Incorrect interconnection 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.

• When using an extension cable, connect it to the extension cable connector of the base unit

securely.

Check the connection for looseness.

Poor contact may cause incorrect input or output.

• When using a memory card, fully insert it into the memory card slot.

Check that it is inserted completely.

Poor contact may cause malfunction.

• Shut off the external power supply for the system in all phases before mounting or removing the

module.

Failure to do so may result in damage to the product.

• Do not touch the module during turning on electricity and immediately after power supply

interception. There is fear of a burn.

• Do not directly touch any conductive parts and electronic components of the module.

Doing so can cause malfunction or failure of the module.
