1-4 Precautions
Be sure to read before handling.
Handling
Caution
1. Avoid excessive vibration or impact to the positioner body and any excessive force to the
armature, as these actions may cause damage to the product. Handle carefully while transporting
and operating.
2. If being used in a place where vibration occurs, using a binding band is recommended to prevent
broken wires because of the vibration.
3. When exposed to possible moisture invasion, please take the necessary measures. For example, if
the positioner is left onsite for long periods, a plug should be put in the piping port and a body
cover unit fitted to avoid water penetration.
Take measures to avoid dew condensation inside the positioner if exposed to high temperature and
humidity. Take enough measures against condensation especially when packing for export.
4. Keep magnetic field off the positioner, as this affects its characteristics.
Air Supply
Caution
1. Use only dehumidified and dust extracted clean compressed air as the air supply.
2. Use only dehumidified and dust extracted clean compressed clean air as the positioner contains
extrafine orifices such as restrictor and nozzle.
Do not use a lubricator.
3. Do not use compressed air containing chemicals, organic solvents, salinity or corrosive gases, as
this may cause malfunction.
4. When operating below the freezing point, protect the positioner from freezing.
Operating Environment
Caution
1. Do not operate in locations with an atmosphere of corrosive gases, chemicals, sea water, or where
these substances will adhere to the regulator.
2. Do not operate out of the indicated operation temperature range as this may cause damage to
electronic parts and seal materials to deteriorate.
3. Do not operate in locations where excessive vibration or impact occurs.
4. If the body cover is being installed in a place where the body cover is exposed to direct sunlight,
the use of a standard body cover without the LCD window is recommended.
