Benefits from Pneumatronics and LRU concepts• The adoption of the Pneumatronics:– dramatically reduces wiring and connectors, typical source ofunreliability and installation costs, between electronic unitsand pneumatic components– reduces piping between pneumatic components spread onpanel– reduces the overall function cost• The adoption of LRU concept– Reduces the “on board train” troubleshooting– Dramatically shorten the “train stop time” requested formaintenance• The overall result is a sensible positive impact on theLCCRoberto TioneEPAC: Electro-Pneumatic Advanced Control• EPAC and EPAC-LITE implement “full brake control” equipment:– Weighted Service Brake, electronic closed loop control– Safety Brake purely pneumatic, assisted by pneumatic weight control,independent from electronics and software: this particular Safetyimplementation has so far allowed the EPAC software to be specifiedand developed at SIL0, without impacts on the overall Brake SystemSafety level– EPAC implements WSP “per axle” valves inside the unit, EPAC-LITEcontrols up-to 4 external WSP valves and speed sensors.– Parking Brake configurable according with various Countrydependent requirements– Magnetic Track Brake pneumatic control– Spare Pneumatic Control for Sanding devices or Scubbers• No external additional electronics is needed:– All Brake Control, WSP based on UIC approved algorithms,communication protocols (MVB, Echelon, CAN, ETHERNET, RS485)are implemented inside the unit– Wide-flexible range of I/O’s, digital and analog, active and passive,configurable upon application request, applicable to TCI or to bogiediagnosisRoberto Tione
