The signal converter is self-monitoring and registers the following faults:
1. Ultrasonic signal errors and application errors.
2. Cable faults in sensor cable and current output loop.
3. Operation and setting errors.
4. Internal faults in the signal converter.
These faults and errors are displayed immediately in the form of two flashing triangles .
The individual faults are stored in two registers. Current faults are stored in ERROR PENDING, and
current and past faults are stored in ERROR LOG.
The faults are stored in the form of an error code, with indication of elapsed time since error
registration. Power off erases the content of the ERROR LOG.

In SONO 3000, errors can also be indicated by the relay, but only when the relay is set at ERROR
in the menu OUTPUT SETUP.
When the converter is being set (user code keyed in), error indication via relay is
automatically blocked.
