- When you plan to use SHARP programmable controllers (hereafter referred to as "PLCs"),
you are requested to design each system so that even if a fault or malfunction occurs within
the PLC, it will not lead to a serious accident in your system. You should incorporate back-up
measures and fail-safe features in your system that will thoroughly protect your system from
malfunctions if a fault or error occurs in the PLC.
- SHARP PLCs are designed and manufactured with the idea that they will be used in general
applications in ordinary industries. Therefore, they must not be used in specific applications
that can affect the health or safety of the public, such as nuclear power plants and other
power generating plants. Such applications require a special warranty of quality that SHARP
explicitly does NOT offer for these PLCs. However, if a user will certify that he/she does not
requires a special quality warranty on the PLC, and will limit the use of the PLC to non critical
areas of these applications, SHARP will agree to such use.
If you are planning to use SHARP PLCs for applications that may affect the lives of human
beings and property, and you need particularly high reliability performance, such as in the
fields of aviation, medicine, transportation, combustion and fuel processing equipment,
passenger cars, amusement park rides, and safety equipment, please contact our sales division
so that we can confirm the required specifications.
- Though this manual is produced with the almost care, if you have any questions and inquiries,
please feel free to contact our dealers.
