10.3. Emergency Run Operation
In normal operation the LV-DS is controlled via a remote two-wire signal (terminals 56, 57).
Emergency Run is controlled by a two-wire circuit connected to Input A (terminals 53, 55). Closing Input A
causes the LV-DS to run the motor and ignore certain trip conditions.
