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.
Before you attempt to provide a solution (machine or process) for a specific application using the POUs found in the library, you must consider, conduct and complete best practices. These practices include, but are not limited to, risk analysis, functional safety, component compatibility, testing and system validation as they relate to this library.
|
|
|
IMPROPER USE OF POUS |
|
oPerform a safety-related analysis for the application and the devices installed. oEnsure that the POUs are compatible with the devices in the system and have no unintended effects on the proper functioning of the system. oUse appropriate parameters, especially limit values, and observe machine wear and stop behavior. oVerify that the sensors and actuators are compatible with the selected POUs. oThoroughly test all functions during verification and commissioning in all operation modes. oProvide independent methods for critical control functions (emergency stop, conditions for limit values being exceeded, etc.) according to a safety-related analysis, respective rules, and regulations. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
oOnly use software approved by Schneider Electric for use with this equipment. oUpdate your application program every time you change the physical hardware configuration. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
Incomplete file transfers, such as data files, application files and/or firmware files, may have serious consequences for your machine or controller. If you remove power, or if there is a power outage or communication interruption during a file transfer, your machine may become inoperative, or your application may attempt to operate on a corrupted data file. If an interruption occurs, reattempt the transfer. Be sure to include in your risk analysis the impact of corrupted data files.
|
|
|
UNINTENDED EQUIPMENT OPERATION, DATA LOSS, OR FILE CORRUPTION |
|
oDo not interrupt an ongoing data transfer. oIf the transfer is interrupted for any reason, re-initiate the transfer. oDo not place your machine into service until the file transfer has completed successfully, unless you have accounted for corrupted files in your risk analysis and have taken appropriate steps to prevent any potentially serious consequences due to unsuccessful file transfers. |

Failure to follow these instructions can result in death, serious injury, or equipment damage. |
