Sierra Smart-Trak 100 Quick Installation Manual

SAFETY
1. Apply power only after reviewing the wiring diagrams for both your Smart‐Trak Model 100 Meter or Controller,
and the Compod. See reverse for Compod wiring, see 100 Series Quick Installation Guide or 100 Series Operators
Manual for wiring information.
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. Insure you follow all Smart‐Trak Meters and Controllers installation
recommendations.
2. Wire your instrument per the diagramed pinout on the back of this card and in the Instruction Manual (specific
wiring is required for both the Smart‐Trak itself, port P3, as well as the Compod). Power is applied to both the
Smart‐Trak and Compod via the HD DB15 connector (P3) on your 100 Series, or can be chained through multiple
units using the Compod P1 and P2 connectors. Please refer to your Compod manual for more information
regarding the convenience of daisy chaining.
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 Smart‐Trak 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. The green LED above the RJ45 connector will light
when the unit powered.
2. Our Mass Flow Controllers are shipped with a zero setpoint in Automatic valve operation mode. 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 Smart‐Trak Meter will begin to measure mass flow. This will be displayed on
the user software or on your DD Compod. You can cycle through the DD Display options using the button on the
bottom right corner of the Compod.
4. Controllers will likely need a setpoint input in order to control flow. Do so carefully! You can digitally input a
setpoint using the RS‐232 user software or via Compod MODBUS. You can still control directly with your analog
setpoint source via 100 Series HD DB15. NOTE: You can change the setpoint source type using the RS‐232 software
or the included Compod User Software (RS‐485 GUI). The unit ships in the configuration initially chosen (or default
if not specified). This information is also listed on the Data Label and on the Calibration Certificate. This
information is also inherent in the model code. See the Manual for details.
5. DO NOT leave a setpoint applied for an extended period of time to a controller when the gas supply is off or
blocked. Damage may result from excessive heating, and the unit will become hot enough to burn you.
Alternatively, you can maintain your setpoint value, but close the valve by switching Valve Operation to Closed
digitally with the user software or the pilot module, or with an analog ground to the appropriate pin (see over).
6. The Compod User Software is a complete GUI (Graphic User Interface) to set and use all Compod functions. If you
chose not to use this program, you may use a basic trial MODBUS program like KEPServerEX , which can be used to
access the registers and modify accordingly. We do not support KEPServerEX. It can be used for simple
functionality testing. You must write your own MODBUS program if you choose not to use the Compod User
Software.
