(2) Automatic restart. Can result in death, serious injury, or property damage.
Faults caused by incorrect control voltage, a missing load, or a phase failure (refer to chapter
3RW30: LEDs and troubleshooting [Page 44]) are automatically reset when the system
returns to normal. An automatic restart is initiated and the 3RW restarted if a start command
is present at the input.
If you do not want the motor to start automatically, you must integrate suitable additional
components, e.g. phase failure or load monitoring devices, into the control and main circuits.
