Once you have installed and configured a transmitter, you are ready to
start up the process loop. Startup usually includes
• Simulate pressure and temperature inputs to the transmitter,
• Reading inputs and outputs
• Checking zero input
You can also run an optional output check to "wring out" an analog loop
and check out individual PV outputs (in DE mode) prior to startup.
The actual steps in the startup procedure will vary based on the transmitter
type, the piping arrangement and the measurement application. In general,
we use the SCT to check the transmitter's input and output under static
process conditions, simulate input signals and make adjustments as
required before putting the transmitter into full operation with the running
process.
For SMV transmitters that are digitally integrated with Honeywell's
TPS/TDC systems, note that simulated PV readings on Universal Station
displays will be flagged as BAD PV although the "PVRAW" reading will
continue to be displayed will reflect the simulated input.
