About Startup

Step Procedures

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.

BAD PV displayed on TPS/TDC systems

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.
