ALARM - ERROR CONFIGURATION
This section is dedicated to all the possible error causes for
alarm generation, and to the actions performed according
to the alarm configuration (setup menu “Error configura-
tion”) .
Each alarm cause can be referred to an error to which an
error code is assigned and which is logged in a dedicated
memory space (see “Event logging” section for more de-
tails) .
Five configuring actions are foreseen upon generation of
an alarm:
1.
Alarm relay de-energized;
2.
Auto-cleaning (control actions are stopped during auto-
cleaning mode; can be enabled only for the “Reference
electrode broken or dirty” error);
3.
3 .6 or 22 mA fault current for the 4-20 mA output; 22
mA fault current for the 0-20 mA output;
4.
Hold mode (entered in any case for the following errors:
EEPROM corruption, serial bus error) .
5.
SMS sending to the selected telephone numbers in order
to advise of error occurrence .
Note
The red LED flashes in any case upon generation of an
alarm, i .e . it can not be disabled by changing the error
configuration .
Here is a table with errors, error codes and default error
handling configuration:
