Page 7: Disposal Of Bender Devices
LINETRAXX® RCM420 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 Intended use The AC and pulsed DC sensitive residual current monitor RCM420 (Type A) from Bender is designed for fault and residual current monitoring in earthed power supply systems (TN/TT systems) where an alarm is to be activated in the event of a fault, but disconnection must be prevented. In addition, the device can be used to monitor single conductors, such as PE conductors, N-PE connections and PE-PAS connections. -
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... -

= X1:X2 = 100:10 = 10. The correction factor can be set via the SEt/n menu. The correction factor is factory set to 1 and relates to normal operation with one Bender measuring current transformer only (X = 600:1). Commissioning Prior to commissioning, check proper connection of the residual current monitor. -
