Warning!

manufacturer of the hot tap equipment and/or the contractor performing the hot tap is responsible for providing proof of such a permit.

Warning!

to a power source and to peripheral devices. Failure to do so could result in injury or death. All AC power connections must be in accordance with published CE directives.

Warning!

sensors and/or damage to the electronics.

Warning!

Agency approval for hazardous location installations varies between flow meter models. Consult the flow meter

Hot tapping must be performed by a trained professional. U.S. regulations often require a hot tap permit. The

All wiring procedures must be performed with the power off.

To avoid potential electric shock, follow National Electric Code safety practices or your local code when wiring this unit

Do not power the flow meter with the sensor remote (if applicable) wires disconnected. This could cause over-heating of the

Before attempting any flow meter repair, verify that the line is de-pressurized.

Always remove main power before disassembling any part of the mass flow meter.

Caution!

Caution!

You cannot add or subtract wire length without returning the meter to the factory for re-calibration.

Caution!

before installing the meter.

Caution!

precautions to minimize the risk of damage:

All flow meter connections, isolation valves and fittings for hot tapping must have the same or higher pressure rating

Changing the length of cables or interchanging sensors or sensor wiring will affect the accuracy of the flow meter.

When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at full gas flow

The AC wire insulation temperature rating must meet or exceed 80°C (176°F).

Printed circuit boards are sensitive to electrostatic discharge. To avoid damaging the board, follow these

 before handling the assembly, discharge your body by touching a grounded, metal object  handle all cards by their edges unless otherwise required  when possible, use grounded electrostatic discharge wrist straps when handling sensitive components

Note and Safety Information

We use caution and warning statements throughout this book to draw your attention to important information.

Receipt of System Components

When receiving a Sierra mass flow meter, carefully check the outside

packing

carton for damage incurred in shipment. If the carton is damaged, notify the local carrier and submit a report to the factory or distributor. Remove the packing slip and check that all ordered components are present. Make sure any spare parts or accessories are not discarded with the packing material. Do not return any equipment to the factory without first contacting Sierra Customer Service

Technical Assistance

If you encounter a problem with your flow meter, review the configuration information for each step of the installation, operation, and setup procedures. Verify that your settings and adjustments are consistent with factory recommendations. Installation and troubleshooting information can be found in the SteelMass™ 640S and FlatTrak™ 780S

(includes 780S-UHP and 760S) Series product manuals.

If the problem persists after following the troubleshooting procedures outlined in the 640S or 780S product manuals, contact Sierra Instruments by fax or by E-mail (see inside front cover). For urgent phone support you may call (800) 866-0200 or (831) 373-0200 between 8:00 a.m. and 5:00 p.m. PST. In Europe, contact Sierra Instruments Europe at +31 20

This document describes the function and operation of the optional HART interface for the Sierra Instruments flow meter. The 600/700 Series HART provides different process variables: Instantaneous Flow, Totalized Flow, User Full Scale, and K-Factor. Instantaneous flow can be selected as Velocity, or Mass units. The Totalizer output provides totalized mass flow. The K-factor provides a Flow Correction Factor for Velocity and Mass Flow.

This document specifies all the variables for a HART configured 640S, 760S, 780S, and 780S-UHP. The HART signal output is provided through an extension protocol that is fully integrated into the 640S, 760S, 780S, and 780S-UHP models.

HART Commands

The 600/700 Series HART meter supports the HART Universal and Device specific commands.

640S/780S SIP Configurator

The SIP software gives access to the 600/700 Series HART functions and features. It can be used to configure the basic flow meter setup, and advance functions. The SIP Software configurator interfaces through the 600/700 Series HART RS-232 Serial port and a PC USB RS-232 port.

Device Variables and Dynamic Variables

Through the Dynamic Variable Assignment the Device Variables are mapped to the four Dynamic Variables: Primary (PV), Secondary (SV), Tertiary (TV) and Quaternary (QV). The assignment is performed using Common Practice Command 50.

Device Variables Classification

The Device Variable Classification is determined by the process measurement type and will determine the Engineering Unit that is supported. The tables below show the Device Variable Classes and the related Engineering Units supported by the Sierra Instruments 600/700 Series HART.
