WARNING

LOSS OF CONTROL

• The control scheme designer must consider the potential failure

modes of control paths.

• Certain critical control functions, provide a means to achieve a safe

state during and after a path failure.

• Separate or redundant control paths must be provided for critical

control functions.

• System control paths may include communication links.

Consideration must be given to the implications of unanticipated

transmission delays or failures of the link.

Failure to follow this instruction can result in death, serious injury,

or equipment damage.
