Starting Up Transmitter

Procedure
SMV Model SMA125
Start-up Procedure
86
NOTE: Perform the procedure in Section 7.4, Using the Transmitter to Simulate PV
Input, before performing these start-up procedures
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.

Step
1 Make sure that all valves on the three-valve manifold are closed.
See Figure 26 for sample piping arrangement.
2 For analog loops, make sure the receiver instrument in the loop is
configured for the PV4 output range.
3 Connect SCT to SMV and establish communications. (See
subsection 5.2 for procedure, if necessary.)
4 Be sure any switches that may trip alarms or interlocks associated
with analog loops are secured or turned off.
5 Perform Upload of the SMV database to the SCT.
6 Open equalizer valve C.
7 Open 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.
8 Select 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.
