• The PLC will turn OFF all outputs when its self-diagnosis function detects

any error or when a severe failure alarm (FALS) instruction is executed.
As a countermeasure for such errors, external safety measures must be
provided to ensure safety in the system.

• The PLC outputs may remain ON or OFF due to deposition or burning of

the output relays or destruction of the output transistors. As a counter-
measure for such problems, external safety measures must be provided
to ensure safety in the system.

• When the 24-VDC output (service power supply to the PLC) is overloaded

or short-circuited, the voltage may drop and result in the outputs being
turned OFF. As a countermeasure for such problems, external safety
measures must be provided to ensure safety in the system.

!Caution

Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Otherwise, the input signals may not be
readable.

!Caution

Confirm safety at the destination node before transferring a program to
another node or changing contents of the I/O memory area. Doing either of
these without confirming safety may result in injury.

!Caution

Do not operate the control system in the following locations:

• Locations subject to direct sunlight.

• Locations subject to temperatures or humidity outside the range specified

in the specifications.

• Locations subject to condensation as the result of severe changes in tem-

perature.

• Locations subject to corrosive or flammable gases.

• Locations subject to dust (especially iron dust) or salts.

• Locations subject to exposure to water, oil, or chemicals.

• Locations subject to shock or vibration.

!Caution

Take appropriate and sufficient countermeasures when installing systems in
the following locations:

• Locations subject to static electricity or other forms of noise.

• Locations subject to strong electromagnetic fields.

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.

!Caution

The operating environment of the PLC System can have a large effect on the
longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi-
tions at installation and remains within the specified conditions during the life
of the system.
