It is very likely that the original question has not
correctly copied the error code.

"wran sensor 2" is most likely "WARN SENSOR 2"

It is impossible to search electronic pdf documents if the
error message is spelled incorrectly.

This is why employers look for things like misspellings in
documents submitted by job candidates, it shows whether the
candidate pays attention to details.

Here is what the 3144P manual says about the WARN error
message:

"The transmitter is still operating, but something is not
correct. Possible causes of this condition
include, but are not limited to, an out-of-range sensor, a
fixed loop, or an open sensor condition. In the
case of a Sensor 2 failure with Hot Backup enabled, the
Process Variable line displays “WARN,” and the
Process Variable Unit line alternates between “SNSR 2”
and “RANGE.” "

We do have a problem in the company that is one PT connected to PlC which is mean 1 out of 1 in PLC system we do have the PAHH is 55 mbar and PALL 8 mbar with a timer of 15 sec for the PAHH the problem started when PAHH goes more than the set point which is 55 it reached up to 71 but due to timer doesn't trip . We force it and we checked everything nothing there . We replaced the transmitter problem still there the reading goes more than the 55 bar the range for transmitte is 0- 60 mbar . So we did loop check , aculaizing valve , wiring all are okay . What the possible causes for this ???
