    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 an NJ-series Controller. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.

  • Page 16

    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 17

    Safety Precautions Warnings 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 18

    Safety Precautions 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. Provide measures in the communications system and user program to ensure safety in the overall system even if errors or malfunctions occur in data link communications or remote I/O communications.

  • Page 19

    Safety Precautions Cautions 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 20: 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 21

    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 22

    Precautions for Safe Use • Setting DIP switches or rotary switches • 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.

  • Page 23

    Precautions for Safe Use Debugging • Forced refreshing ignores the results of user program execution and refreshes I/O with the specified values. If forced refreshing is used for inputs for which I/O refreshing is not supported, the inputs will first take the specified values, but they will then be overwritten by the user program. This operation differs from the force-set/reset functionality of the CJ-series PLCs.

  • Page 24

    Precautions for Safe Use • After you transfer the user program, the CPU Unit is restarted and communications with the Ether- CAT slaves are cut off. During that period, the slave outputs behave according to the slave specifica- tions. The time that communications are cut off depends on the EtherCAT network configuration. Before you transfer the user program, confirm that the system will not be adversely affected.

  • Page 25: Restoring Data

    Precautions for Safe Use Restoring Data • You cannot back up, restore, or compare some or all of the settings for certain slaves and Units. Also, you cannot back up, restore, or compare data for disabled slaves or Units. After you restore data, suf- ficiently confirm that operation is correct before you start actual operation.

  • Page 27: Error Processing

    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 28: Battery Replacement

    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.

    • If you return a faulty Unit for repair, describe the problem in as much detail as possible, enclose this description with the Unit, and return the Unit to your OMRON representative. • For poor contact, take a clean cotton cloth, soak the cloth in industrial alcohol, and carefully wipe the contacts clean.

  • Page 238: Replacing The Battery

    6 Inspection and Maintenance Replacing the Battery The Battery in the NJ-series CPU Unit must be replaced periodically as preventative maintenance. (The Battery is a backup power supply for the CPU Unit's internal clock and the variables that are retained during power interruptions.) This section describes how to replace the Battery.

  • Page 239

    6 Inspection and Maintenance Low Battery Indicators If the Controller Setup has been set to detect a low-battery error, the ERROR indicator on the front of the CPU Unit will flash when the battery is nearly discharged. If the ERROR indicator flashes, connect the Sysmac Studio, and then check the CPU Unit's Battery connection if the Sysmac Studio shows a Low Battery Voltage, Battery-backup Memory Check Error, or Clock Oscillator Stopped event.

  • Page 240

    6 Inspection and Maintenance Replacement Procedure Use the following procedure to replace the battery when the previous battery has become completely discharged. Precautions for Safe Use We recommend replacing the battery with the power OFF to prevent the CPU Unit's sensitive internal components from being damaged by static electricity.

  • Page 241: Operation Without A Battery

    6 Inspection and Maintenance Additional Information The Low Battery Voltage event is cleared automatically the next time the Controller is turned ON after replacing the Battery. 6-2-2 Operation without a Battery NJ-series CPU Units do not support a battery-free operation function such as CJ-series CPU Units. If a Battery is not connected or the Battery voltage is too low, the following operation occurs.

    Appendices Load Short-circuit Protection and Line Disconnection Detection for CJ- series Basic I/O Units A-4-1 Load Short-circuit Protection and Line Disconnection Detection for CJ1W-OD202 This section describes the load short-circuit protection and line disconnection detection of the CJ1W- OD202 Output Units. As shown below, normally when the output bit (OUT) turns ON, the transistor will turn ON and then out- put current (Iout) will flow.

    Appendices Figure 3 Operation for Disconnected Line with Output Current below the Line Disconnection Detection Current A: Load not connected or load line broken. B: Current to load at or below line disconnection detection current. C: Rise of current to load too slow and error detected before the disconnection detection current was reached.

    Appendices  Programming Example In this example, CJ1W-OD202 is mounted in slot 0 of rack 0. This example shows how to change output Jxx_Ch0_Out00 to FALSE immediately if the Alarm Out- put Bit _CJB_IOUnitInfo[0,0,0] changes to TRUE and how to keep the output FALSE until the cause is removed and the bit is reset with RstOD202.

    Appendices A-4-2 Load Short-circuit Protection for CJ1W- OD204/OD212/OD232/MD232 As shown below, normally when the output bit turns ON (OUT), the transistor will turn ON and then out- put current (Iout) will flow. If the output current (Iout) exceeds the detection current (Ilim) when an over- load or short-circuit occurs, the output current (Iout) will be limited as shown in Figure 2.

  • Page 342

    Appendices  Restrictions If a short-circuit occurs in an external load, immediately turn OFF the corresponding output and remove the cause. An alarm output bit that corresponds to the external load output number is turned ON. There is an alarm output bit for every common. When an alarm output bit turns ON, use a self-holding bit for the alarm in the user program and turn OFF the corresponding output.

    Appendices EMC Directive Measures for Relay Outputs The NJ-series Controllers conform to the Common Emission Standards (EN 61000-6-4 or EN 61131-2) of the EMC Directives. However, noise generated by relay output switching may not satisfy these Stan- dards when the Controller is incorporated into a system. In such a case, a noise filter must be con- nected to the load side or other appropriate countermeasures must be provided external to the Controller.
