  • Page 5: Safety Instructions

    Observe the associated safety instructions! 1.3 Intended use The AC/DC sensitive residual current monitoring module RCMB102 is used for monitoring residual currents in charging stations for electric vehicles where direct and/or alternating residual currents are likely to occur the value of which is constantly greater than zero. This also applies to the detection of leakage currents.

  • Page 6: Warranty And Liability

    1.4 Warranty and liability Bender devices are designed and built in accordance with the state of the art and accepted rules in respect of technical safety. However, the use of such devices may introduce risks to the life and limb of the user or third parties and/or result in damage to Bender devices or other property.

  • Page 7: Function

    The control input (X10) will also be queried. Depending on the sequence of the HIGH/LOW levels applied, the RCMB102 can be reset with or without a self test, calibration and activation of the test winding (test current supply).

  • Page 8: Starting Sequence

    2.3 Starting sequence Once the residual current monitoring module is connected to the power supply, the automatic starting sequence begins. The residual current monitoring module RCMB102 is supplied by an external power supply. Note: Users must ensure that the supply voltages +U...

  • Page 10: Analogue Voltage Output X1

    Function 2.4 Analogue voltage output X1 The r.m.s. value of the currently measured residual current is available at X1 as a proportional output voltage. If the residual current monitoring module detects values outside the measuring range, the analogue output X1 will be set to 4.85 V. As soon as the residual current drops below 10 mA, the output X1 will still remain at 4.85 V for approx.

  • Page 11: Reset Function

    Function 2.6.2 Reset function A reset of the residual current monitoring module can be carried out at any time via the control input X10. For activating the reset function, a LOW level is to be applied across the control input X10 for at least T1 >...

  • Page 13 Function The signalling sequence at the control input X10, illustrated in the preceding diagram, results in a self test as a reset and subsequent calibration. The self test includes a test of the supply voltage before and after zero point measurement. If the supply voltage is outside the tolerance, calibration will be repeated.
