  • Page 16: Safety Precautions

    Safety Precautions Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of a CJ-series Analog I/O Unit. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
  • Page 17 Safety Precautions Symbols The circle and slash symbol indicates operations that you must not do. The specific operation is shown in the circle and explained in text. This example indicates prohibiting disassembly. The triangle symbol indicates precautions (including warnings). The specific operation is shown in the triangle and explained in text. This example indicates a precaution for electric shock.
  • Page 18 Safety Precautions WARNING During Power Supply Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. Do not attempt to take any Unit apart. In particular, high-voltage parts are present in the Power Supply Unit while power is supplied or immediately after power is turned OFF.
  • Page 19 Safety Precautions WARNING Fail-safe Measures Unintended outputs may occur when an error occurs in variable memory or in memory used for CJ-series Units. As a countermeasure for such prob- lems, external safety measures must be provided to ensure safe operation of the system.
  • Page 20 Safety Precautions Caution Application Do not touch any Unit when power is being supplied or immediately after the power supply is turned OFF. Doing so may result in burn injury. Wiring Be sure that all terminal screws and cable connector screws are tightened to the torque specified in the relevant manuals.

  • Page 21: Precautions For Safe Use

    Precautions for Safe Use Precautions for Safe Use Disassembly and Dropping • Do not attempt to disassemble, repair, or modify any Units. Doing so may result in malfunction or fire. • Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit malfunc- tion or burning.
  • Page 22 Precautions for Safe Use • Do not apply voltages or connect loads to the Output Units or slaves in excess of the maximum rat- ings. • Surge current occurs when the power supply is turned ON. When selecting fuses or breakers for external circuits, consider the above precaution and allow sufficient margin in shut-off performance.
  • Page 23 Precautions for Safe Use • Connecting cables or wiring the system • Connecting or disconnecting the connectors The Power Supply Unit may continue to supply power to the rest of the Controller for a few seconds after the power supply turns OFF. The PWR indicator is lit during this time. Confirm that the PWR indicator is not lit before you perform any of the above.
  • Page 24 CAT slaves are cut off. During that period, the slave outputs behave according to the slave settings. The time that communications are cut off depends on the EtherCAT network configuration. If the EtherCAT network configuration contains only OMRON EtherCAT slaves, communications are cut off for a maximum of 45 seconds.
  • Page 25 Precautions for Safe Use • If the Fail-soft Operation parameter is set to stop operation, process data communications will stop for all slaves when an EtherCAT communications error is detected in a slave. For this reason, if Servo Drives are connected, the Servos for all axes will be turned OFF. Make sure that the Fail-soft Operation parameter setting results in safe operation when a device error occurs.
  • Page 26 Precautions for Safe Use • Apply power for at least five minutes before changing the Battery. Install a new Battery within five minutes (at 25°C) of turning OFF the power supply. If power is not supplied for at least 5 minutes, the saved data may be lost.

  • Page 27: Precautions For Correct Use

    Precautions for Correct Use Precautions for Correct Use Storage, Mounting, and Wiring • Do not operate or store the Controller in the following locations. Operation may stop or malfunctions may occur. • Locations subject to direct sunlight • Locations subject to temperatures or humidity outside the range specified in the specifications •...
  • Page 28 Precautions for Correct Use Error Processing • In applications that use the results of instructions that read the error status, consider the affect on the system when errors are detected and program error processing accordingly. For example, even the detection of a minor error, such as Battery replacement during operation, can affect the system depending on how the user program is written.
  • Page 29 Precautions for Correct Use Battery Replacement • Be sure to install a replacement Battery within two years of the production date shown on the Battery label. • Turn ON the power after replacing the Battery for a CPU Unit that has been unused for a long time. Leaving the CPU Unit unused again without turning ON the power even once after the Battery is replaced may result in a shorter Battery life.
  • Page 30 Precautions for Correct Use SD Memory Cards • Insert the SD Memory Card all the way. • Do not turn OFF the power supply to the Controller during SD Memory Card access. The files may be corrupted. If there is a corrupted file in the SD Memory Card, the file is automatically deleted by the restoration function when the power supply is turned ON.
