SAFETY PRECAUTIONS
(Read these precautions before use.)
Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full
attention to safety in order to handle the product correctly.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be
impaired.
This manual classifies the safety precautions into two categories: [ WARNING] and [ CAUTION].
Depending on the circumstances, procedures indicated by [ CAUTION] may also cause severe injury.
It is important to follow all precautions for personal safety.
Store this manual in a safe place so that it can be read whenever necessary. Always forward it to the end user.
[DESIGN PRECAUTIONS]
WARNING
●Make sure to set up the following safety circuits outside the PLC to ensure safe system operation
even during external power supply problems or PLC failure. Otherwise, malfunctions may cause
serious accidents.
- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock
circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to
prevent damage to the equipment at the upper and lower positioning limits.)
- Note that when the CPU module detects an error, such as a watchdog timer error, during self-
diagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU
module occurs in an input/output control block, output control may be disabled. External circuits
and mechanisms should be designed to ensure safe machinery operation in such a case.
- Note that the output current of the 24 V DC service power supply varies depending on the model
and the absence/presence of extension modules. If an overload occurs, the voltage automatically
drops, inputs in the PLC are disabled, and all outputs are turned off. External circuits and
mechanisms should be designed to ensure safe machine operation in such a case.
- Note that when an error occurs in a relay, transistor or triac of an output circuit, the output might
stay on or off. For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery operation in such a case.
●Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the PLC in operation.
Read the manual thoroughly and ensure complete safety before executing other controls (for program
change, parameter change, forcible output and operation status change) of the PLC in operation.
Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.
●In an output circuit, when a load current exceeding the current rating 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.
●For the operating status of each station after a communication failure of the network, refer to relevant
manuals for the network. Incorrect output or malfunction may result in an accident.
WARNING 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 injury or property damage.

CAUTION
●When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on. Take
proper measures so that the flowing current does not exceed the value corresponding to the
maximum load specification of the resistance load.
●After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of this variation in time.
●Simultaneously turn on and off the power supplies of the CPU module and extension modules.
●If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned
off. When the power supply is restored, it will automatically restart (when the RUN/STOP/RESET
switch is on RUN side).
