You are responsible for determining if this mass flow meter is appropriate for your oxygen application.
  • Page 3 Warnings and Cautions “Warning,” “Attention,” and “Note” statements are used throughout this manual to draw your attention to important information. Symbol Key Symbol Symbol Descripition Meaning “Warning” statements appear with information that is important to protect people and equipment from damage. Pay very close Warning attention to all warnings that apply to your application.
  • Page 4 Warning! Do not power the flow meter with the sensor remote (if applicable) wires disconnected. This could cause over-heating of the sensors and/or damage to the electronics. Warning! Before attempting any flow meter repair, verify that the line is de-pressurized. Warning! Always remove main power before disassembling any part of the mass flow meter.
  • Page 5 Warranty Statement All Sierra products are warranted to be free from defects in material and workmanship and will be repaired or replaced at no charge to Buyer, provided return or rejection of product is made within a reasonable period but no longer than one (1) year for calibration and non-calibration defects, from date of delivery.

    Chapter 1: Introduction This manual will explain the function and operation of the optional BACnet interface for Sierra Instruments ® InnovaMass 240i/241i iSeries vortex mass flow meter. ® This document is intended to be a complement to other 240i/241i documentation by providing a complete description of the InnovaMass iSeries from a BACnet communication perspective.

  • Page 8: Chapter 2: Bacnet Installation

    Chapter 2: BACnet Installation Overview 2-Wire Topology RS-485 Network BACnet MS/TP uses a common 2-wire RS-485 (EIA-485) physical layer, so all of the same RS-485 wiring practices apply. Devices should be wired using a daisy chain topology and the last device should have a 120Ω termination resistor to prevent reflections.

  • Page 9: Electrical Connections

    Electrical Connections-Input All electrical connections are made on the terminal board inside the InnovaMass enclosure. For detailed instructions on installing your InnovaMass iSeries meter, please read the InnovaMass 240i/241i Instruction Manual. For complete wiring instructions please see Chapter 2 of the 240i/241i instruction manual. Input Power Wiring AC Power Wiring The AC power wire size must be 26 to 16 AWG with the wire stripped 1/4 inch (6 mm).

  • Page 10: Dc Power Wiring

    The AC wire insulation temperature rating must meet or exceed 80 °C (176°F). DC Power Wiring The DC power wire size must be 26 to 16 AWG with the wire stripped 1/4 inch (6 mm). Connect 24 VDC +/- 10% (0.4 amp load, maximum) to the terminals marked on the terminal block. Connect the earth ground wire to the safety ground log.

  • Page 11: Connecting The Rs-485 Network Wires

    Connecting the RS-485 Network Wires Caution! The InnovaMass is equipped with an optical isolated RS-485 interface. Grounding the RS-485 common (15) would defeat this. 1. Connect your 2-wire RS-485 network to terminal 13 (A-) and your wire RS-485 to terminal 14 (B +). 2.

  • Page 12: Terminator

    Terminator Reflections in a transmission line can cause communication errors. To minimize the reflection, it is required to place 120Ω terminator resistors at both ends of the cable. Never place a terminator resistor somewhere along the cable. Some gateways, PLCs, and other types of devices have terminator resistors built-in. If so, do not add another one.
  • Page 13 6. Wires between RS-485 devices need to be wired in a daisy-chain pattern. They should never be wired with separate home-runs back to the master in a Star pattern. When daisy chaining the Modbus A/B wires you should either twist the wires together and solder or use a crimp ferrule, this would still allow the bus to be connected even if the meter A/B wires were disconnected at one 240i.

  • Page 14: Chapter 3: Innovamass 240I/241I Com Settings

    Chapter 3: InnovaMass 240i/241i Com Settings The BACnet MS/TP bus can be configured using the InnovaMass 240i/241i SIP. It can communicate at one of three baud rates: 9600, 19200 and 38400. It is very important that all of the devices on the MS/TP bus be set to communicate at the same baud rate.

    1. Verify polarity on the communication cable. RS-485 achieves binary transmission by switching the voltage polarity between A- and B+. The differential voltage should be between 7V and 1.5V while the bus is actively communicating. Sierra verifies the 240i/241i is correct per the EIA RS-485 spec. Caution! We have found cases where other devices with “A”...
