Table 24 Start up Procedure for SMV Transmitter Model SMA110,
continued
Step Action
3
For analog loops, make sure the receiver instrument in the loop is
configured for the PV4 output range.
4
Connect SCT to SMV and establish communications. (See
subsection 5.2 for procedure, if necessary.)
5
Be sure any switches that may trip alarms or interlocks associated
with analog loops are secured or turned off.
6
Perform Upload of the SMV database to the SCT.
7
Open valve A and equalizer valve C in the three-valve manifold.
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.
9
While monitoring the transmitter’s PV1 input, position the transmitter
so that the transmitter input is reading at or near zero and then
tighten the mounting bolts completely.
Note that you must click on Read Input in order to obtain updated
input pressure
• When input reads 0% input, go to step 10.
• If input does not read 0% input,
- Click the Input option button.
- Click the Correct button to correct input to zero.
10
Close equalizer valve C and open valve B, or remove the tubing from
between the input ports and restore transmitter piping.
11
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.
12
Select TempInCal tab card and read input of applied temperature
(PV3) input in desired engineering unit. Verify that it is equivalent to
process temperature.
13
Close equalizer valve C and open valve B.
14
In 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.
