4. TROUBLESHOOTING
4.1. To check the flowmeter functionality most fully make sure that measured
values are displayed and that all setting parameters are entered and set
within the required range.
4.2. In self-test mode, the flowmeter has the automatic monitoring functional-
ity which displays flowmeter status words which register alarm situa-
tions, failures and faults.
Current state of the flowmeter measuring channels is displayed in
windows
STATUS LOGS / Current status / CURR. STATUS chan.
1
(
2,3,4
)
as the following status words:
-
ER
– alarm situation measuring channel status word
-
DS
– output status word
-
FL
– failure status word.
Also, the ER status word is displayed in windows of zoomed indica-
tion of measured parameters current values.
Status word is displayed as a sign-position code
– a combination of
characters "
-
"
и "
". Character "
-
" shows that an event did not occur,
character "
"
– that it did.
Status word contents, possible causes of some faults and ER sit-
uations, and troubleshooting methods are described in Appendix D.
To determine the type of the ER situation that occurred in a meas-
uring channel and is displayed in the measured value zoomed indica-
tion window, open window
STATUS
LOGS / Current status
(
CURR.
STATUS chan. X
)
/ ER
(
ER chan. X
) of the corresponding channel.
Besides the ER situation type name, this window shows the ER situa-
tion start time and duration.
4.3. An ER situation is an event characterized by mismatch of measured
values and flowmeter metrological characteristics, or by impossibility of
measurements due to the violation of measurement conditions. An ER
situation is registered when its duration exceeds 1 second.
Secondary measuring converter processes ER situations as fol-
lows: when the ER situation occurrence condition is met character "
"
shows in the certain place of the status word (error message), and upon
completion the ER situation start time, end time and duration is record-
ed to the archive. The
Inert. time
ER situation (alarm condition) is not
recorded to archives.
The flowmeter power supply failure is also recorded to an archive.
Depending on the ER type the CS can stop flowrate measuring,
volume accumulating and recording dead time values. The CS starts
recording dead time value when volume accumulation is stopped.
4.4. Ultrasonic signal (USS) failure is processed depending on the ratio of
USS failure duration and the preset setting value
Inert. time
in menu
SETTINGS / Processing settings
, which can be set between 5 and
300 s.
