4Operating Environment Precautions
xiii
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
• The PC 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 coun-
termeasure for such errors, external safety measures must be provided to en-
sure safety in the system.
• The PC outputs may remain ON or OFF due to deposition or burning of the
output relays or destruction of the output transistors. As a countermeasure 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 PC) 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 Tighten the screws on the terminal block of the AC Power Supply Unit to the
torque specified in the operation manual. The loose screws may result in burning
or malfunction.
Caution When using the C200HW-PA209R Power Supply Unit with an 8-slot or 10-slot
CPU Backplane or Expansion I/O Backplane, be sure to use only Backplanes
with “-V1” at the end of the model number. Using an 8-slot or 10-slot Backplane
without “-V1” at the end of the model number may result in malfunction due to
deterioration of the base or pattern burnout. The 3-slot and 5-slot Backplanes do
not come in “-V1” models, and models without “-V1” can be used.
4 Operating Environment Precautions
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 tempera-
ture.
• 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.
