3.6.17 Automatic restart function (option L32)
With option "Automatic restart" (L32), the system automatically restarts when the line supply
fails, irrespective of how long the line supply failure was. Alarms are acknowledged
automatically and the drive is restarted.
Voltage Sensing Module (VSM)
With the "Automatic restart" option, a Voltage Sensing Module VSM10 is integrated in the drive.
The VSM10 acquires the actual voltage values at the medium-voltage level upstream of the
circuit breaker.
When the medium voltage is restored after a power failure, this is detected by the open-loop/
closed-loop controllers via voltage transformers when the input-side circuit breaker has
dropped out. The voltage transformers should be located at the medium-voltage level upstream
of the circuit breaker.
For safety reasons, a time limit between the power failure and the maximum permissible power
restoration time is incorporated to ensure that the drive does not restart in an uncontrolled
manner. As a further warning, an acoustic signal is output when the drive restarts.
You can find further information on the Voltage Sensing Module (VSM10) in Section
"Description of the Components".
