Section 2 <strong>Scanner</strong> ® <strong>2000</strong> microEFM<br />

3. Connect the <strong>Scanner</strong> <strong>2000</strong> and manifold assembly to the differential pressure meter. Hardware requirements<br />

will vary, depending upon the installation configuration. However, minimally, an adapter is required<br />

that can span between the threaded pressure tap/orifice flange connector and the non-threaded<br />

manifold. This adapter can be a one-piece stabilizer (often preferred for added strength and stability) or a<br />

short heavy wall pipe nipple attached to a futbol flange (available from Cameron). Use a suitable compound<br />

or tape on all threaded process connections.<br />

4. Install the explosion-proof Barton Model 21 RTD assembly in the thermowell. Route the RTD assembly<br />

cable through the conduit opening in the top of the <strong>Scanner</strong> <strong>2000</strong> to connect to the main circuit board. (If<br />

the Barton Model 21 assembly is not used and the <strong>Scanner</strong> <strong>2000</strong> is in a hazardous area, a Barton Model<br />

20 RTD terminal housing or similar alternative must be used. In this case, the RTD signal cable must be<br />

routed through conduit and a conduit seal must be installed within 18 in. of the <strong>Scanner</strong> <strong>2000</strong>. A wiring<br />

diagram for the RTD assembly is provided in .<br />

5. Route any additional inputs/outputs or COM connections, etc. through the conduit opening in the top of<br />

the <strong>Scanner</strong> <strong>2000</strong>. In hazardous environments, add a conduit seal within 18 inches of the <strong>Scanner</strong> <strong>2000</strong>.<br />

Figure 3.5, page 64.<br />

6. Perform a manifold leak test as described on page 52.<br />

7. Verify the zero offset, if required (and other calibration points, if desired). See the ModWorX Pro Software<br />

User Manual, Part No. 9A-30165025, for complete instructions. See also Zero Offset (Static Pressure<br />

or Differential Pressure), page 53, Static Pressure Calibration and Verification, page 53, and Differential<br />

Pressure Calibration and Verification, page 54.<br />

CAUTION Do not put the <strong>Scanner</strong> into operation until the valves are positioned properly so that<br />

pressure is supplied to both sides of the MVT. For instructions on proper valve positions,<br />

see Placing the <strong>Scanner</strong> into Operation, page 55.<br />
