PBUS System

PBUS Components

Information of currents and voltages you get with the active shunts SHC and/or SHL. To get the level information of your tank sensors into the PBUS network you need the interface CMT. It receives all the information, supplies the sensors and provides this informations to the system network. All adjustments needed as type of sensor, capacity of the tank, alarm thresholds etc. will be done by the system monitor PSM. You can connect up to four tanks (with different characteristics) to the CMT. As remote battery switch with deep discharge and overvoltage protection you can use the FBC 265. AC-data you get from the interface CMW. It transfers the data from the ACW3-interface to the PBUS. The switch-over units LAU provide AC-data for the PBUS too. You can find these units here: "Shore power//Switch over units for several sources".

While configurating a PBUS system, please take care to order also needed cables.

If you want to see your P-BUS data not only on the System Monitor PSM, but also on the chart plotter or
other NMEA2000® compatible devices you need a NMEA2000® Bridge, which converts the data accordingly.
Following PGN are supported:

PGN 127501, PGN 127505, PGN 127506, PGN 127508, PGN 127744, PGN127747, PGN 127750.

Please check, which PGN can be displayed actually, because this depends on the manufacturer and Software revision. Delivery includes a M12-T-cable. Power supply via the NMEA2000® - network.
