Automatic restart
The automatic restart function detects failures in the mains voltage and ensures, depending on the duration of
the failure, a direct or delayed restart so that the continuity of the process is guaranteed.
5.7.1
Mains failure detection
The Starter Control Unit continuously monitors the condition of the mains. As soon as the mains voltage drops
below 65% of the nominal voltage there is a mains failure (see figure 16). As soon as the mains voltage returns
to a value > 90% of the nominal voltage, the mains voltage is considered healthy.
