  • Page 7: Disposal Of Bender Devices

    LINETRAXX® RCMA423 Disposal of Bender devices Abide by the national regulations and laws governing the disposal of this device. For more information on the disposal of Bender devices, refer to www.bender.de > service & support. 1.10 Safety If the device is used outside the Federal Republic of Germany, the applicable local standards and regulations must be complied with.
  • Page 8: Function

    Function Function Intended use The AC/DC sensitive residual current monitor RCMA423 is designed for use in earthed systems (TN and TT systems) where DC and AC fault currents may occur. These are in particular loads containing six-pulse rectifiers or one way rectifiers with smoothing, such as converters, battery chargers, construction site equipment with frequency-controlled drives.
  • Page 9: Connection Monitoring

    2.3.5 Functional faults If an internal functional fault occurs, all three LEDs flash. An error code will appear on the display (E01…E32). In such a case please contact the Bender Service. 2.3.6 Set the number of reload cycles If faults occur only temporarily, but recurrently, in the system being monitored, with the fault memory M deactivated, the alarm relays would switch synchronously to the error status.
  • Page 10: Residual Current Monitoring In Window Discriminator Mode

    Function If the residual current increases above or falls below the response value the response time t expires. After the expiry of the response time an alarm is signalled. A set response delay t (0…10 s) adds up to the device- on1/2 related operating time t and delays alarm signalling (total delay time t...
