  • Page 278: Periodic Maintenance And Inspection

    6 Inspection and Maintenance Periodic Maintenance and Inspection Daily or periodic inspections are required in order to maintain the Controller's functions in peak operat- ing condition. 6-1-1 Periodic Inspection Although the major components in NJ-series Controllers have an extremely long life time, they can deteriorate under improper environmental conditions.

  • Page 279: Unit Replacement Precautions

    • 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 280: 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 281 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 Real-Time Clock Stopped event.
  • Page 282 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 283: 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.
  • Page 380 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.
  • Page 381 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 383 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.

  • Page 384: Emc Directive Measures For Relay Outputs

    Appendices EMC Directive Measures for Relay Outputs The NJ-series Controllers conform to the Common Emission Standards (EN 61131-2) of the EMC Directives. However, noise generated by relay output switching may not satisfy these Standards when the Controller is incorporated into a system. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the Controller.
  • Page 385 Appendices Current Circuit Characteristic Required element The varistor method prevents the Varistor method imposition of high voltage between the contacts by using the constant voltage characteristic of the varis- tor. There is a delay in the resetting time. Power supply If the supply voltage is 24 or 48 V, insert the varistor in parallel with the load.
