SMV Model SMA125 Start-up Procedure

The following procedures outline the steps for starting up SMV 3000 transmitters in flow measurement applications. Refer to the appropriate start-up procedure for SMV transmitter used in your process application.

•Table 22 for SMV 3000 Model SMA125 (PV2 measures AP)

•Table 23 for SMV 3000 Model SMG170 (PV2 measure GP)

•Table 24 for SMV 3000 Model SMA110 (PV2 measures AP) (draft range transmitter) and SMV transmitters with small differential pressure spans.

Refer to Figure 26 for the piping arrangement and equipment used for the procedure. Typical meter and SCT (or SFC) connections are also shown in the figure.

Table 22 Start up Procedure for SMV Transmitter Model SMA125

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.

6Open equalizer valve C.

7Open valve A to make differential pressure zero (0) by applying same pressure to both sides of meter body.

Allow system to stabilize at full static pressure - zero differential.

8Select DPInCal tab card and read input of applied DP (PV1) pressure in the selected engineering unit.

•If input reads 0% input, go to step 9.

•If input does not read 0% input,

-Click the Input option button.

-Click the Correct button to correct input to zero.
