6.2.1. List of possible faults, failures and alarm situations detected by the flow
meter and displayedon the LCD with "
X
" character in the "
ERR = - - - - - -
"
line is given in Table 7. A sign-position code is read from
right
to
left
.
Table 7
Sign position number
Explanation
1
Devise Error
2
Battery low level
3
USS is not present
4
Maximum flowrate is exceeded
5
Flowrate exceeds the universal output upper limit
6
Flowrate exceeds the universal output lower limit
6.2.2. The same information can be read via the communication interface from
the
Status
tab of the "Monitor BUF (310)" program (see section 4.1.5). In
the event of a fault, the LED on the corresponding line lights up red.
6.2.3. If
X
symbol is displayed in position 1 or the indicator lights up in red in the
Devise Error
line in the
Status
tab, the flow meter shall be forwarded for
repair.
6.2.4. If
X
is displayed in other positions, or the lights are red in other lines of
the
Status
tab, and/or in case of no pulses at Universal output, check the
following:
- Liquid is present and running through the pipeline
-
Air is not collected in the flow meter’s location;
- The universal output conversion factor and flow rate cutoffs are correct;
change their values if necessary.
If the above checks are positive, you should contact the device man-
ufacturer to determine the possibility of its further operation.
6.2.5. Past emergencies are recorded in the device archive and can be viewed
via the serial interface in the
Data log
tab, selecting the type of archive
and time interval. The assignment of the 16-position code in the column
of emergency situations of the archive from the 1st to 6th positions (from
right to left) corresponds to the one specified in Table 7. The presence of
a fault is indicated by the number "1", while the absence is indicated by
the number "0".
