Simple'Bus'Network Links Vacuum Loaders

摘要

The new FlexBus control system,based on the CAN-bus network concept,uses a single cable to connect a vacuum pump with one or many individually controlled receivers and easily accommodates addition of more stations.Introduced by Novatec,Inc.,Baltimore,FlexBus consists of a pump control,onboard controls for each receiver,CAN-bus cable,T-connectors for each receiver wiring junction along the cable,and an optional hand-held pendant that provides advanced control over purging,proportioning,monitoring,and changing of loading functions.Changes to a receiver control made with the pendant are stored in that receiver,so the pendant can be used with mul-.tiple receivers.It also plugs into the pump control to adjust vacuum breaker timing.
