Endura APA592
pH / Redox (ORP) transmitter

8.1 Diagnostic Messages

Diagnostic messages are related to 5 conditions:
1. Process diagnostics – the process setup or sensor connected to the APA592–PH 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's DTM software only.

Some diagnostic messages can be masked (see Section 8.2.2, page 80). 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 (Loop Test) mode.
[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 HMI or a HART configurator (DTM / Hand held)
to place transmitter back into normal operating
mode (Remove from Loop Test – Fixed output
mode) if the current operating conditions allow.
Contact factory.
