Keep spare parts on hand:
- We recommend that you stock up on maintenance parts including spare modules.
- Preventive maintenance (replacement of the module or its battery) is required for
using the module beyond 10 years. For enquiries on battery replacement service
(for purchase), contact your nearest Yokogawa Electric representative or sales
office. (The module has a built-in lithium battery. Lithium batteries may exhibit
decreased voltage, and in rare cases, leakage problems after 10 years.)
Discharge static electricity before operating the system:
- Because static charge can accumulate in dry conditions, first touch grounded metal
to discharge any static electricity before touching the system.
Never use solvents such as paint thinner for cleaning:
- Gently clean the surfaces of the FA-M3 controller with a cloth that has been soaked
in water or a neutral detergent and wringed.
- Do not use volatile solvents such as benzine or paint thinner or chemicals for
cleaning, as they may cause deformity, discoloration, or malfunctioning.
Avoid storing the FA-M3 controller in places with high temperature or
humidity:
- Since the CPU module has a built-in battery, avoid storage in places with high
temperature or humidity.
- Since the service life of the battery is drastically reduced by exposure to high
temperatures, take special care (storage temperature should be from -20°C to
75°C).
- There is a built-in lithium battery in a CPU module and temperature control module
which serves as backup power supply for programs, device information and
configuration information. The service life of this battery is more than 10 years in
standby mode at room temperature. Take note that the service life of the battery
may be shortened when installed or stored at locations of extreme low or high
temperatures. Therefore, we recommend that modules with built-in batteries be
stored at room temperature.
Always turn off the power before installing or removing modules:
- Failing to turn off the power supply when installing or removing modules, may result
in damage.
Do not touch components in the module:
- In some modules you can remove the right-side cover and install ROM packs or
change switch settings. While doing this, do not touch any components on the
printed-circuit board, otherwise components may be damaged and modules may fail
to work.
Do not use unused terminals:
- Do not connect wires to unused terminals on a terminal block or in a connector.
Doing so may adversely affect the functions of the module.
