Broken wire detection
Asdescribedinsection"Measuringcircut",themeasuringcircuitsL(+)/L(-)
andtheprotectiveconductorsPE1/PE2areconstantlymonitoredforwire
breaks–notonlyatPower-Onoramanualoroccasionalautomatictest.
The response time of monitoring is only a few seconds. Broken wire
detection between L(+) and L(-) is performed via coupled alternating
voltage. This alternating voltage is short-circuited if the terminals are
connectedtotheconnectedmainsatlow-resistance.Thedevicedetects
thatthemainstobemonitoredisproperlyconnected.
