SmartTrak® 50 Series Low & Medium Flow Quick Install Guide
47-0443 B
SmartTrak® 50 Series Low & Medium Flow
Quick Install Guide
INTRODUCTION
Congratulations on your purchase of the SmartTrak® 50 Series digital gas mass flow meter/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
st
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.
3.
Apply the gas
listed on the Data Label
to the inlet at the recommended pressure (listed on the Data Label/Calibration
Certificate). Your 50 Series will begin to measure mass flow. This will be displayed on the user software or local display.
4.
You will need a setpoint input in order to control flow.
Do so carefully!
You can digitally input a setpoint using the user
software or control directly with your analog setpoint source if you ordered the analog option.
NOTE:
The unit ships in
