Warnings and Cautions



Warning!

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

nameplate for specific flow meter approvalsbefore any hazardous location installation.

Warning!

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

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

permit.

Warning!

All wiring procedures must be performed with the power off.

Warning!

To avoid potential electric shock, follow National Electric Code safety practicesor your local code when wiring this unit 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 accor-

dance with published CE directives.

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.

Caution!

Before making adjustments to the device, verify the flow meter is not actively monitoring or reporting to any master control

system. Adjustments to the electronics will cause direct changes to flow control settings.

Caution!

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

the main pipeline.

Caution!

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

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

Caution!

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

before installing the meter.

Caution!

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

Caution!

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

precautions to minimize the risk of damage:

•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

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 QuadraTherm 640i/780i product manual.

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

Chapter 1: Introduction

This document describes the function and operation of the optional HART interface for the Sierra

Instruments flow meter. The QuadraTherm 640i/780i complies with HART Protocol Revision 7.4.

This document specifies all the device specific features and documents HART Protocol

implementation details (e.g., the engineering unit codes supported). The functionality of the

QuadraTherm (field device) is described sufficiently to allow its proper application in a process and

its complete support in HART capable host applications.

This manual is designed to complement other documentation (e.g., the QuadraTherm 640i/780i

product manual) by providing a complete, unambiguous description of the QuadraTherm 640i/780i

from a HART Communication perspective. It is also intended to be a technical reference for HART

capable host application developers, system integrators and knowledgeable end users. This manual

provides functional specifications used during Field Device configuration, maintenance and testing.

This document assumes the reader is familiar with HART Protocol requirements and terminology.

Note

In this manual 640i/780i HART refers to product models 640i and 780i.
