10.2.1 Calibration
When an error occurs, the device checks after 30 seconds of waiting time whether the error condi-
tions still exist. If this is the case, a further check is performed after an additional 30 seconds. If the
error conditions still exist after a total of 5 intervals of 30 seconds each, the device aborts the cali-
bration process.
