6.5 Status and error messages
6.5.1 Device status
Error data is given if you use PACTware™ software with the appropriate DTM on a PC. The
sofware will show a symbol on the bottom left of the window if one or more error conditions are
found. This data agrees with NAMUR Recommendation NE 107 (Self-Monitoring and Diagnosis of
Field Devices) and VDI/VDE 2650.
Types of error message
For data on errors, refer to Error handling on page 40.
NE 107 status Type of
error
Description
Failure Error If an error message is shown on the diagnostics screen in the DTM, the current
output goes to the error signal value set in "Signal output", menu item "range
current output".
Out of specification Warning If a warning message is shown, there is no effect on the current output value.

Description Error type Possible errors
Failure The device does not operate
correctly. The fault message
stays on.

Function
check
The device operates correctly,
but the measured value is
incorrect. This fault message is
only temporary. This symbol is
shown when the user configures
the device with the DTM or a
HART® Communicator.
– –
Out of
specification
It is possible that the measured
value is unstable if the operating
conditions do not agree with the
device specification.
Warning Signal weak
Warning Signal strong
Warning Spectrum quality bad
Warning Measurement old
Maintenance The device does not operate
correctly because of bad
environmental conditions (e.g.
build-up on the antenna). The
measured value is correct, but
maintenance is neccessary a
short time after this symbol is
shown.
Warning Sweep timing error
Warning CPLD revision mismatch
Warning Capacitor voltage low
Information This status message is shown at
the same time as the error "no
measuring value".
