Quick Start Guide

Smart-Trak® 50 Series

INTRODUCTION

Congratulations on your purchase of the

Smart-Trak® 50 Series digital gas mass flow controller designed to

meet the low-cost budgetary requirements of OEM’s while maintaining excellent quality and performance. This

reference guide is not

meant to replace the Instruction Manual included on the CD-ROM in your shipment, but

rather is a great supplement to it that will help you install and operate your instrument and begin to measure or

control mass flow.

SAFETY 1

1. Apply power only after reviewing the wiring diagrams on page 2 of this guide or in the Instruction

Manual.

2. Apply gas flow only after checking plumbing connections for leaks.

3. NEVER TEST FOR LEAKS WITH LIQUID LEAK DETECTOR. If liquid seeps into the

electronics or the hidden sensor compartment, the instrument may be damaged. Instead use a

pressure-decay test (if liquid MUST be used at all, limit it to the fittings and keep it off the body of

the instrument).

INSTALLATION

1. Consult the instrument’s Data Label (on the back of the instrument) for ALL proper operating

parameters. If the information on the Data Label does not match your process conditions, contact

your Representative or Sierra Instruments Customer Service at the contact information on the footer

of the sheet.

2. Install a 10 micron in-line filter upstream of your instrument. If the gas contains any moisture,

use an appropriate dryer or desiccant. Particles larger than 10 micron and moisture may damage your

instrument.

3. Mount according to Data Label orientation. Horizontal flow is preferable and factory default

unless the factory calibration was performed specifically for vertical flow upward or downward, as

listed. Orientation is listed on Data Label and on the Calibration Certificate.

4. This instrument is not a loop-powered device! Do NOT apply power to the 4-20 mA / 0-5 VDC

output or setpoint connections.

5. Wire your instrument per the diagramed pin-out on the back of this card and in Chapter 2 of the

Instruction Manual. For convenience of wiring, there are two DB9 connector ports; the unused DB9

is capped off. Apply power to your choice of port and cap unused port. It is recommended you

allow 15 minutes for the instrument to warm up for maximum accuracy.

OPERATION

1. Power the unit. If you are using the Sierra provided power supply, it is recommended you attach the

D-sub connector to the 50 Series before plugging the adapter into the wall. The unit may take longer

to start than normal if otherwise. This will not damage the unit in any way.

2. Our Mass Flow Controllers with a digital setpoint option are shipped with a zero setpoint in the

power-up setpoint box in the software. For safety considerations, it is recommended YOU

confirm this prior to applying gas to the unit.
