4. Precautions against long-term use
Use of Azbil Corporation’s products, including switches, which contain electronic components, over a prolonged period may degrade
insulation or increase contact-resistance and may result in heat generation or any other similar problem causing such product or switch
to develop safety hazards such as smoking, ignition, and electrification. Although acceleration of the above situation varies depending
on the conditions or environment of use of the products, you are required not to use any Azbil Corporation’s products for a period
exceeding ten (10) years unless otherwise stated in specifications or instruction manuals.
5. Recommendation for renewal
Mechanical components, such as relays and switches, used for Azbil Corporation’s products will reach the end of their life due to wear by
repetitious open/close operations.
In addition, electronic components such as electrolytic capacitors will reach the end of their life due to aged deterioration based on
the conditions or environment in which such electronic components are used. Although acceleration of the above situation varies
depending on the conditions or environment of use, the number of open/close operations of relays, etc. as prescribed in specifications
or instruction manuals, or depending on the design margin of your machine or equipment, you are required to renew any Azbil
Corporation’s products every 5 to 10 years unless otherwise specified in specifications or instruction manuals. System products, field
instruments (sensors such as pressure/flow/level sensors, regulating valves, etc.) will reach the end of their life due to aged deterioration
of parts. For those parts that will reach the end of their life due to aged deterioration, recommended replacement cycles are prescribed.
You are required to replace parts based on such recommended replacement cycles.
6. Other precautions
Prior to your use of Azbil Corporation’s products, you are required to understand and comply with specifications (e.g., conditions and
environment of use), precautions, warnings/cautions/notices as set forth in the technical documents prepared for individual Azbil
Corporation’s products, such as catalogs, specifications, and instruction manuals to ensure the quality, reliability, and safety of those
products.
