Appendix C:
Service, Maintenance, and Disposal
The designer of any control scheme must consider the potential failure modes of control paths
and, for certain critical functions, provide a means to achieve a safe state during and after a
path failure. Examples of critical control functions are EMERGENCY STOP, overtravel stop,
power outage, and restart.
WARNING
LOSS OF CONTROL
• Separate or redundant control paths must be provided for critical functions.
• System control paths may include communication links. Consideration must be given to the
implication of unanticipated transmission delays or failures of the link.
• Observe all accident prevention regulations and local safety guidelines 1.
• Each implementation of the product 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.

Opening the LMD heat sinks can affect factory-set encoder alignment and impact hMT. Tamper
seals ensure factory hardware settings remain unaltered and match the encoder alignment set
during the manufacturing process. If a tamper seal is broken, the LMD product warranty is void.
