WARNING
Automatic restart.
May result in death, serious injury or damage to property.
The automatic reset mode (RESET MODE) must not be used in applications where an unexpected restart of the motor after the
recovery time has elapsed may lead to personal injury or damage to property.
The start command (e.g. by the PLC) must be reset before a reset command, since an automatic restart is executed when a start
command is pending after the reset command. This especially applies to motor protection tripping. For safety reasons we recommend
you integrate the group fault output (terminals 95 and 96) into the control.
