Major Faults
The DMC 3000 conducts periodic self tests every 10 minutes in
Run
,
Pause
and
Sleep
modes. Most of the tests
are also performed every second in
Run
mode. All the main functions are controlled by the microcontroller and
all the data, parameters and configurations integrity are protected by the CRC16.
The calibrations and algorithm parameters are protected by the CRC16 and saved inside a specific and dedica-
ted EEPROM. The different DC voltages on the electronic board are periodically measured and controlled.
If a fault is detected, an alarm is generated and a message is alternately shown with the measure on the display.
A major fault prevents the DMC 3000 from going into RUN mode
(*) See 5.6.3 for the list of faults and solutions to perform
