Transmitter diagnostics

The transmitter provides some diagnostics messages to the user in case of faults or conditions out of the
specification.

Diagnostic messages

Diagnostics messages are provided by Digital LCD Integral Display or by Hart communication using the
proper external tools.

Diagnostics on the Digital LCD Integral Display (Hart version)

The diagnostics messages below listed can appear on the Digital LCD Integral Display. The corrective
actions are also suggested (see the common corrective actions description at the end of the message list).
Electronic Fail
There are internal inconsistencies in the data base of the HART (secondary) electronic
Corrective actions: 1, 2, 3
Sensor Invalid
There are internal inconsistencies in the data base of the transducer (primary) electronic. This test is
performed at the start up.
Corrective actions: 1, 2, 4
Sensor Fail
The reading from the sensor is wrong
Corrective actions: 1, 2, 4
PV out of Limit
The calculated PV is above 110% or below –110% of sensor limit (LRL/URL on the instrument nameplate).
Corrective actions: 5.
Static P Out Lim
The detected static pressure is above the maximum static pressure (MWP on the instrument nameplate).
Corrective actions: 5.
Overrange
The detected pressure is above the maximum static pressure (MWP on the instrument nameplate).
Corrective actions: 5.
Sensor T Out Lim
The sensor temperature is above + 90 °C or below – 50°C.
Corrective actions: 5.
Current Out Satur
The output is limited to the saturation limits, but the measurement is beyond these limits.
The measured variable could be outside the configured span.
Corrective actions: 5
Current Out Fixed
The output is fixed to a value set by a HART command for simulation purposes
Corrective actions: Use the HART command to exit the simulation mode. If the transmitter is not in simulation
mode see 1, 2, 3.
DAC Out of Range
The Digital to Analog Converter (DAC) is out of range
Corrective actions: It is necessary to carry out an Output Trimming operation specified in this manual. If the
error persists see 1, 2, 3 or 4.
Electr. T Out Lim
The temperature of the HART electronic is above 90 °C or below –50°C.
