■Handling
① Avoid giving impact to the body and torque motor of positioner, and giving excessive force to
armature because it leads to failure. Handle with care during transport and operation.
② When the positioner is used in places subject to vibrations, it is recommended that a tie
wrap be used to prevent the lead wires from breaking.
③ If the positioner is left unused at the operation site for an extended period, ensure the
body cover unit is fitted, and mount a plug on the wiring and piping ports. If the
atmosphere is of high temperature or high humidity, take measures to avoid condensation
inside. The condensation control measures must be taken thoroughly for export
shipment.
④ When removing the positioner from the actuator and mounting it onto another actuator,
malfunctions may occur due to its remained initial constant. When the positioner is transferred
onto another actuator, apply input current, initialize the parameters in the calibration
mode, (parameter code: C80) and perform initial adjustments before supplying air.
■Air Supply
① Use dehumidified and dust-removed clean air as the supplying air source.
② Positioner has fine paths in it. Therefore please use clean air which is dehydrated and
filtered, and also avoid employing Lubricator which causes malfunction. In addition, it is
recommended to use a mist separator as an air-cleaning equipment.
③ Avoid using compressed air containing chemicals, synthetic fluid including organic
solvent, salinity, and corrosive gas as it may cause malfunction.
④ If atmosphere is below freezing point, take measure to avoid condensation.
■Environment
① Do not use in an environment where the product is exposed to corrosive gas, chemicals, salt
water, water or steam.
② If the positioner is used under temperature outside of the specification, the sealing
materials deteriorate quicker and also the positioner may not operate normally.
③ When positioner is installed where its body cover is exposed to direct sunlight, standard
body cover which does not have LCD check window is recommended.
