Select APInCal tab card and read input of applied AP (PV2) pressure
in the selected engineering unit. Verify that it is equivalent to absolute
pressure at zero point.

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.

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 

Make sure that all valves on the three-valve manifold are closed.

See Figure 26 for sample piping arrangement.

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

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

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

Perform Upload of the SMV database to the SCT.

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

Select 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.
