6.3. CommunicationcharacteristicsCompact NS100 to 630053172siIn shortIntegration of the circuit breaker or theswitch-disconnector in a supervisonsystem requires either the communicatingauxiliaries or the SC150 interface.Compact devices fit perfectly in the SMSPowerlogic electrical installationmanagement system by communicatingusing Digipact protocols. An externalgateway offers communication via othernetworks including:b Profibusb Ethernet…There are two possibilities for the 100 to 630 A range:b communicating auxiliariesThey replace the standard auxiliaries and connect directly to the Digipact bus.Three equipment levels:v communicating auxiliary contacts, comprising:- OF (on/off), SD (trip indication) and SDE (fault-trip indication) contacts- electronic module- prefabricated wiring.v communicating auxiliary contacts and motor-mechanism module, comprising:- OF (on/off), SD (trip indication) and SDE (fault-trip indication) contacts- motor-mechanism module (220 V AC) (1)- electronic module- prefabricated wiring.v communicating carriage switches for the chassis, comprising:- CE / CD (connected/disconnected position) contacts- electronic module- wiring connector.b SC150 interfaceUsing the SC150 interface, it is possible to integrate a device equipped with noncommunicatingauxiliaries into a supervison system.The SC150 interface is used to connect:v the auxiliary contacts on the circuit breaker (OF, SD, SDE, SDV, CD, CE)v the remote-operation system (on, off, reset)v the communication output for the STR53UE and STR43ME electronic trip unitsequipped with the COM optionv an unassigned digital input.054481si054516siCompact NS equipped with communicating auxiliary contactsand motor-mechanism module.Withdrawable Compact NS on its chassis equipped withcommunicating auxiliary contacts.Compact withcommunicating SC150auxiliariesdevice identificationaddress b brating - -indication of status conditionsOF (on/off) b bSD (trip indication) b bSDE (fault-trip indication) b bCE/CD (connected/disconnected position) b bcontrolsON/OFF b bLED reset b bprotection settingsReading of the protection settingsoperating and maintenance aidsMeasurements:currentsbFault readings:type of faultbIndications:operation counter b b(1) For voltages other than 220 V AC, use a standard motor-mechanism module (noncommunicating)together with an SC150 indication and control interface.bSC150 indication and control interface.71
