LOW LINE ALARM

Was bedeutet 406 ?

This alarm indicates that the input AC line voltage has sagged more than 10% below the nominal line voltage, as configured by parameter #9. This is a warning and does not automatically shut down the DSD 412 drive, but it suggests that preventative action may be required to avoid future F904 Low Line shutdown faults.
