LOSS OF CONTROL |
|
oThe designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage and restart. oSeparate or redundant control paths must be provided for critical control functions. oSystem control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link. oObserve all accident prevention regulations and local safety guidelines.1 oEach implementation of this equipment must be individually and thoroughly tested for proper operation before being placed into service. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
1 For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control" and to NEMA ICS 7.1 (latest edition), "Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems" or their equivalent governing your particular location.
