Config. Error
Bad configuration of range and/or transfer function.
Corrective actions: Please follow the setting configuration instruction in the relevant section of th e this
manual. If the error persists see 1, 2, 3 or 4
Sensor Elec. Fail
There are internal inconsistencies in the memory of the primary electronic. This test is performed at the start
up.
Corrective actions: 1, 2, 4
Common corrective actions:
1.
Switch the transmitter off and on to verify if the message appears again
2.
With the HART command 48 it is possible to obtain additional information on the failed component
3.
If the messa ge persists the se condary electronic is suspected to have a failure. If the output is in a
failure status (high or low) the fault is severe and it is necessary to substitute the secondary electronic.
Otherwise the failure i s minor, the signal is still valid but with a l ower accuracy. The secondary
electronic can be substituted when convenient.
4.
If the messa ge persists, the p rimary electronic could be damaged. If the outp ut is i n a failure status
(high or low) the fault is severe and it is necessary to substitute the transducer. Otherwise the failure is
minor, the signal is still valid but with a lowe r accuracy. The transdu cer can be sub stituted when
convenient.
5.
Check the process and ambient conditions (e.g.: pressure, process temperature, ambient temperature
static pressure, etc.) against the sensor and electronics limits. If the conditions are close or outside the
limits, these improper i
functionality. If the conditions are well inside the limits see the corrective actions of point 4 or 3.
