  8. EM3555 Bi-Directional Energy Meter

  9. EM3555 Bi-directional Energy Meter • All the benefits of EM3500 family • All EM3500 family common measurements • Additionally measures both energy delivered and energy received • Full four-quadrant measurement of Reactive Energy • Modbus models additionally support Sun-Spec-compliant register blocks • Common Sun-Spec 1.0 register block • Meter model Sun-Spec 1.1 register block • CSI approved • Great for applications with solar, wind, local generation sources • Also used for applications utilizing re-generative braking (elevators, etc.)

  11. EM3560 BACnet Energy Meter

  12. EM3560 – Native BACnet MS/TP Has measurement capability comparable to EM3550 (with logging added) Key Differentiators from other BACnet meters: • Native BACnet MS/TP protocol • 115.2 kbaud serial communications • Pulse Inputs for other Energy sensors • Native Trend_Log objects (data logging) • Local LCD Display & User Interface What customer benefits do these provide?

  13. Native BACnet MS/TP protocol • Native - built into the meter – does not require a separate gateway and power supply • BACnet MS/TP – as compared to BACnet IP – most meters that support BACnet only support BACnet IP • Most customers WANT BACnet MS/TP rather than BACnet IP • Adding a device with BACnet IP requires a separate network drop on a particular subnet and a dedicated IP address – the installer must request these from the customer’s IT group • Adding a device with BACnet MS/TP can be done easily by the installer using a shielded twisted pair that they can run themselves • To get BACnet IP support, simply add a BACnet router to one or more EM3560 Meters

  14. 115.2 kbaud Serial Comm • A commonly requested feature on other BACnet products is faster baud rate support • A serial (MS/TP) link with multiple devices can only operate as fast as the slowest device • Many BACnet system builders prefer to operate their serial links at 76.8 kbaud • The EM3560 supports this and also adds 115.2 kbaud

  15. Pulse Inputs for other Energy sensors • The Modbus protocol is heavily used by Energy Management systems. • Pulse outputs on Modbus EM355x models let BAS/BMS systems access Energy Consumption while the Energy Management system utilizes the full data set of a meter. • Since BACnet is primarily used by BAS/BMS systems, the need for additional output is not common. • BAS/BMS systems that monitor energy consumption want to see all forms energy consumption • Electrical • Natural Gas • Hot Water • Chilled Water • Steam • The EM3560 provides 2 pulse inputs with accumulators (energy counters) that can be connected to simple flow sensors with pulse outputs, and make their accumulated energy readings available via BACnet.

  16. Native Data Logging • Some system designs specify local storage of measurement history on device • Can be recovered later if local controller or communication link fails • Customers can always set up external Trend Logs on local controllers, but they only store when the local controllers and communication link are operating • EM3560 has three native Trend log objects • Each stores up to 5760 time-stamped records (60 days at 15 min intervals) • Log interval is tied internally to demand interval • Each object can be pointed to any of the 52 Data values • Timestamps do rely on our real-time clock, which does not have a battery backup • Software must generate a BACnet Time_Synchronization event when EM3560 power is restored • An alarm bit (Binary_Object) is provided to indicate if this is needed

  17. LCD Display & User Interface • Simplifies setup & commissioning • Enter or view the Device ID directly • Set up Comm parameters • Many MS/TP products require a PC, special cables, custom software, etc.
