2.2.4. SELF TEST OF THE UNIT.
The MOV system incorporates, thanks to its digital technology, self-test functions that guarantee its correct
operation, and will disable the unit in case of internal orders.
These self-tests are performed both during start-up and normal operation. Tests are carried out on the internal
power supply, program memory (ROM), working memory (RAM), oscillography memory (RAM) and the settings
and calibration memory (EEPROM).
Additionally, a hardware test is included for the signalling LEDs. All of them will light up when pressing the
TARGET RESET button. If this button is pressed for more than one second, the memorised indicators will be
deleted.
2.3. ANALYSIS FUNCTIONS
The MOV system includes event recording and oscillography with time resolution of 1 millisecond. In order
to maintain the integrity of date and time, as well as the oscillography record, there is a capacitor backup for the
internal high-resolution clock and the oscillography memory, with capacity for storing the information during at
least 24 hours after a power supply breakdown.
2.3.1. EVENT RECORDER
The MOV keeps a record of the last 165 events, including date and time (with 1 ms resolution), event type,
current and voltage values when the event occurred, and unit status information.
This record is stored in a non volatile memory and is maintained event without power supply.
The following table shows the possible causes for an event:
