7.1 Power failure/Data backup/Restart
7.1.1 Power failure
If the grid power fails,
- all entered configuration and calibration parameters and
- all the materials written on the built-in memory
are saved.
The clock and the calendar continue to run.
7.1.2 Data backup
The calibration data and parameters as well as all configuration and interface data are
stored in non-volatile (EAROM) memory.
Unauthorized data changing can be prevented by an access code.
The front-panel keys can be disabled.
Additional write protection is provided for calibration data and parameters (see
Chapter
7.1.3.1).
7.1.3 Overwrite protection
7.1.3.1 CAL switch
The CAL switch protects the calibration data and parameters against unauthorized access.
The CAL switch is located on the back of the device.
When the CAL switch is in "opened" position, the calibration data and parameters can be
changed using the PC program or via the ProfiBus connection.
With the CAL switch in the "closed" position, the calibration data (e.g. dead load, SPAN)
and parameters (measuring time, zero tracking etc.) cannot be changed.
