Select TempInCal tab card and read input of applied temp (PV3) input in desired engineering unit. Verify that it is equivalent to process temperature.

Close equalizer valve C and open valve B.

Select the FlowInCal tab card and read input Flow (PV4) signal in desired engineering unit. Verify that it is equivalent to calculated flow rate at operating conditions.

SMV Model SMA125 Start-up Procedure

Use the procedure in Table 23 to start-up an SMV 3000 transmitter model SMG170, which measures gauge pressure as the PV2 input.

Table 23 Start up Procedure for SMV Transmitter Model SMG170

Step Action

1Make sure that all valves on the three-valve manifold are closed. See Figure 26 for sample piping arrangement.

2For analog loops, make sure the receiver instrument in the loop is configured for the PV4 output range.

3Connect SCT to SMV and establish communications. (See subsection 5.2 for procedure, if necessary.)

4Be sure any switches that may trip alarms or interlocks associated with analog loops are secured or turned off.

5Perform Upload of the SMV database to the SCT.

6Vent high pressure and low pressure input ports to atmosphere. Steam applications with filled wet legs should be filled and vented to atmosphere.

7Select GPInCal tab card and read input of applied GP (PV2) pressure.

•If input reads 0% input, go to step 8.

•If input does not read 0% input,

-Select Input option

-Click on Correct.

-Read Input. Input will now read GP pressure at zero point.
