364Ax-Gx Instruction Manual

Transmitter diagnostics

The transmitter provides some diag nostics messages to the user in case of faults or conditi ons out of the
specification.

Diagnostic messages

Diagnostics messages are provided by Digital LCD In tegral Display or by HA RT communication using the
proper external tools.

Diagnostics on the Digital LCD Integral Display (HART version)

The diagnostics messages below listed can a ppear on the Digi tal LCD Inte gral Display. The co rrective
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 th e 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.
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.
Corrective actions: Check the ambient temperature. If it is within the limits see 1, 2, 3.
Consistency Check
The secondary electronic and the primary electronics have not been working together before.
Corrective actions: If this message appears during a replacement, please follow the replacement instruction
in the relevant section of this manual. If the error persists see 1, 2, 3 or 4
