2.2 Description of function
The residual current monitoring module detects the residual current caused by leakage and residual
currents in the conductors passed through the measuring current transformer. The residual current
monitoring module measures AC and DC currents. Disconnection when the DC component of the
residual current reaches a preset value.
A signal in proportion to the DC component is available at the analogue voltage output X1. The
second output (X12) provides a switching signal when values are outside the permissible measuring
range or in case of high or soaring residual currents.
The control input (X10) will also be queried. Depending on the sequence of the HIGH/LOW levels
applied, the RCMB103 can be reset with or without a self test, calibration and activation of the test
winding (test current supply).

Function

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 RCMB103 is supplied by an external power supply.
Supply voltage fluctuations may influence the residual current measurement. To exclude this effect
(particularly during calibration), the starting sequence is as follows:
Supply voltage measurement
1. Once a supply voltage +Us≥ of 5 V is applied, the starting sequence begins .
2. The residual current monitoring module disables the open collector switching output X12
(HIGH level).
Calibration
3. When a supply voltage of +Us ≥11 V is reached, calibration (offset measurement) is started by
the module. It must be ensured that no residual current is flowing.
4. Once calibration is complete, the supply voltage measurement will be repeated. Where the
condition +Us ≥11 V cannot be fulfilled, calibration will be repeated. After successful calibra-
tion, the residual current monitoring module enables the switching output X12 (LOW level).
Test current supply
5. The test winding is supplied with test current for 2 s (two-stage test current). The resulting
measured value is available at X1 and the corresponding switching state is applied to output
X12.
When the current is supplied to the test winding, X1 drops to LOW level. X12 will only be enabled
when a HIGH level is applied at X10.
Other features
6. When the test winding is supplied with current, the behaviour of the residual current module is
determined by the control input X10:
Note:
Users must ensure that the supply voltages +Usund -Usat X2 / X11 are strictly
observed. Otherwise the signals at the outputs X1 and X12 may be outside the
tolerance range!

2.4 Analogue voltage output X1
A signal in proportion to the DC component is available at the analogue voltage output X1.
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 3.5 mA, the output X1 will
still remain at 4.85 V for approx. 1.2 s before the currently measured value will be displayed.
Therefore, the shutdown can be reliably evaluated by the charging control electronics.
Output voltages < 150 mV or > 4.85 V signal a short-circuit, an interruption or a possible fault of the
residual current module. For details about fault detection, refer to page 16.
2.5 Switching output X12
When values are outside the measuring range ( IΔn ≥ 6 mA ) or a fault is detected by the monitoring
module, the switching output X12 will be disabled and signalled by the open collector output X12.
Fig. 2.2: Open collector
Only when the measured value of the residual current falls below 3.5 mA DC for a period of 1.2 s, the
switching output X12 will be enabled again by activating the transistor (LOW level at X12).
In order to check the switching capacity of the open collector output X12, a functional test according
to chapter 2.6.5 can be initiated via the control input X10.
2.6 Control input X10
2.6.1 Cyclical self test
Before each charging cycle, a self test has to be activated (reset with subsequent calibration) by the
charging control electronics via the input X10. This requirement can only be met when sufficient
supply voltage +Us/ -Usis available (> 11 V).
The sequence of the measurement is described in chapter 2.6.4. During the calibration process, also
the digital output X12 switches. The cyclical self test is used to check the measuring function of the
device. This is a measure to ensure that the protective function is guaranteed.

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 > 530 ms.
In this case, the residual current measurement process has to be interrupted.
Fig. 2.3: Reset
The residual current measurement remains active during the period T1. The residual current
measured at the point of time t2 remains stored until the residual current measurement is restarted
after applying a HIGH level at X10 for the period T3 > 5 ms.
2.6.3 Impulse duration for activating a reset
When a LOW level is applied at the control input X10 of the residual current monitoring module for
T < 530 ms, no reset will be carried out. The outputs X1 and X12 will remain unaffected. The residual
current measurement will stay active.
Fig. 2.4: Impulse duration for activating a reset
When the condition is met that a LOW level is applied at the control input X10 for at least
T1 = 530 ms, disturbing pulses will not cause a reset of the residual current monitoring module.

RCMB103_D00044_00_M_XXEN/08.2013
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.
Reset
For activating the reset function, a LOW level is to be applied across the control input X10 for at least
530 ms. The residual current measurement remains active during the time T1. After T1 has elapsed,
the residual current value measured at the time t2 is stored by the residual current monitoring
module . From the time T1 has elapsed until the time residual current measurement is restarted
(when T9 has elapsed), residual current measurement is inactive.
Calibration
A calibration is carried out when T1 has elapsed and a control impulse (HIGH for 50…100 μs) is
applied at the control input X10.
Calibration starts within 10…11 ms (T3). The RCMB disables the open collector switching output X12
(HIGH) and carries out an offset measurement. The DC component of a residual current, still flowing,
results in an incorrect calibration.
The calibration process approx. takes 4.6 s (T4). Once the calibration process is complete, the
switching output X12 (LOW) will be enabled.
Test current supply
After calibration the test winding is supplied with current for 2 s. The measured values resulting from
the two test currents will be provided proportionally at X1 and the corresponding switching states
are applied to X1 (details chapter 2.3).
Repeating calibration
Once the test winding is supplied with current (X12 = LOW), calibration can be repeated as often as
required by applying a new control impulse at X10.
Staring residual current measurement
The residual current monitoring module starts residual current measurement when a HIGH level is
applied at X10 for at least 5 ms (T9).
The residual current measured at the time t2 remains stored until the measurement is restarted.

2.6.5 Functional test switching output X12
Fig. 2.5: Monitor points for the functional test
After starting the functional test via the control input X10 (control impulse HIGH for 50…100 μs), the
charging control electronics should monitor the correct functionality of the digital output X12 at the
following points in time:
Monitor point related to falling edge e1 (X10)
M1 X12 disabled after 0.3 s
Monitor point related to falling edge e2 (X12)
M2 X12 enabled after 0.5 s
M3 X12 disabled after 1.8 s
M4 X12 enabled after 2.3 s
If X10 is maintained at LOW level at the end of the self test, X12 remains disabled until X10 has
reached HIGH level for at least 5 ms. Refer to the diagram in chapter 2.6.4 for more information.
Note:
The falling edge „e2“ is used for the timing of the monitor points M2, M3 and M4.
Therefore, the end of the internal self test at t = 6.6 s may vary if the supply voltage
+Us= 12 V is unstable at the time of e2.

2.7 Values outside the permissible measuring range
Fig. 2.6: Behaviour of the outputs when the values are outside the measuring range
If the residual current exceeds the measuring range (residual current ≥ 6 mA DC), the residual
current monitoring module will disable the open collector output X12 (HIGH) after time T1 has
elapsed. The disconnection time is dependent on the value of the residual current (see chapter 2.8).
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 to 3.5 mA DC, the output X1 will
remain at 4.85 V for approx. 1.2 s before the currently measured value will be displayed. In this way,
the shutdown can be reliably evaluated by the charging control electronics.
