5 Commissioning
The meaning of indicator LEDs and the operating concept are described in Chapter 4.
5.1 Data Backup/Power Failure
The calibration data and parameters as well as all configuration and interface data are stored in a non-
volatile (EAROM) memory. Unauthorized data changing can be prevented by an access code. Additional
write protection is provided for calibration data and parameters (CAL switch, see Chapter 5.1.1).
5.1.1 CAL Switch
The CAL switch protects the calibration data / parameters against unauthorized access.
When the CAL switch is in 'open' 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 (e.g.
measure time, zero tracking etc.) cannot be changed.
The CAL switch is located under a cover that can be opened by
means of a knife.
For ’legal-for-trade’ applications, set the CAL switch (4) to the left
position and seal the cover.
