    PRECAUTIONS This section provides general precautions for using the C200H-PID0j PID Control Unit and related devices. The information contained in this section is important for the safe and reliable application of the C200H-PID0j PID Control Unit. You must read this section and understand the information contained before attempting to set up or operate the C200H-PID0j PID Control Unit.

  • Page 7: Intended Audience

    It is extremely important that a PC and all PC Units be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PC system to the above-mentioned applications.

  • Page 8: Operating Environment Precautions

    Application Precautions 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.
  • Page 9 Application Precautions Caution Failure to abide by the following precautions could lead to faulty operation of the PC or the system, or could damage the PC or PC Units. Always heed these pre- cautions. Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes.
  • Page 10 Application Precautions Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any static built-up. Not doing so may result in malfunction or dam- age.
