8.1 Diagnostic Messages
Diagnostic messages are related to 5 conditions:
1. Process diagnostics – the process setup or sensor connected to the ACA592–XX transmitter.
2. Sensor diagnostics – the sensor, its connections or calibration.
3. Installation diagnostics – HART setup, or, more commonly, during initial installation of the transmitter
or a new sensor.
4. Operating conditions diagnostics – the operating condition of the transmitter, such as the DC voltage
used to power the transmitter.
5. Electronics diagnostics – the transmitter's internal circuitry or the wiring connected to it.
Note.
Sub-error messages are displayed on the transmitter DTM software only.
Some diagnostic messages can be masked (see Section 8.2, page 68).
This function is indicated in column 1 of Table 8.2 (below) where available.

Possible Cause(s)
[Related Condition]
The device configuration has been
changed by a write or set
command or by an operation via
device HMI.
[INSTALLATION: This condition is
not displayed on the HMI. This is
just an indication to the HART
master. It is visible only on the EDD
and DTM]
The analog and digital analog
outputs for the Primary Variable are
held at the requested value. Device
is in fixed current Output hold is
enabled (Loop Test) mode – see
Section 7.3.6, page 60.
[STATUS]
PV related sensor board electronics
malfunction.

8 Troubleshooting and Diagnostics
Corrective Action
Ensure that the copy of the device configuration in
the DTM is the same as the device, (perform a
configuration upload or download as required),
then clear the Configuration Changed flag from the
Extras / Reset menu.
Use a HART configurator (DTM / hand held) to
place device back into normal operating mode
(remove from Loop Test – Fixed output mode).
Contact factory.
