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.
Diagnostic Message
[Sub-error Message]
Possible Cause(s)
[Related Condition]
Corrective Action
Configuration Changed
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]
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.
C090.030
Output hold is enabled
(Loop Test)
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]
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.
F086.000
PV input error
PV related sensor board electronics
malfunction.
