LOSS OF CONTROL
• Assure that the system will reach a safe state during and after a
control path failure.
• Separate or redundant control paths must be provided for critical
control functions.
• Test the effect of transmission delays or failures of communication
links. 1
• Each implementation of equipment using communication links
must be individually and thoroughly tested for proper operation
before placing it in service.
Failure to follow these instructions may cause
injury, death or equipment damage.
Control system design must consider the potential failure modes of
control paths and, for certain critical control functions, provide a
means to acheive a safe state during and after a path failure.
Examples of critical control functions are emergency stop and
over-travel stop.
1 For additional information about anticipated transmission delays or
failures of the link, refer to NEMA ICS 1.1 (latest edition). Safety
Guidelines for the Application, Installation, and Maintenance of
Solid-State Controls or its equivalent in your specific country,
