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 configuration”).

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 details).

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 con-

figuration.

Here is a table with errors, error codes and default error han-

dling configuration:
