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.
