1-3 Precautions
Be sure to read before handling.
Operation
Warning
1. Do not operate the positioner outside the specified range as this may cause problems. (Refer to
the specifications.)
2. Design the system to include a safety circuit to avoid the risk of danger should the positioner
suffer failure.
3. Be sure that exterior lead-in wiring to the terminal box is based on the guidelines for explosion-
protection of manufactory electric equipment when being used as a flame proof, explosion proof
construction.
4. Do not remove terminal cover in a hazardous location while the power is on.
5. Covers for the terminal and body should be in place while operating.
6. When using as an intrinsically safe explosion-proof product, do not wire in a hazardous location
while the power is on.
Caution
1. Do not touch the actuator or valve's oscillating section when supply pressure has been added, as
this is dangerous.
2. Make sure fingers do not get caught when mounting and aligning the cam.
Cut off the pressure supply and always release the compressed air inside the positioner and actuator
before performing this work.
3. Always use with the body cover unit mounted.
Moreover, the positioner may not meet degrees of protection IP66 depending on the body cover
mounting conditions. In order to meet degrees of protection IP66, tighten threads using the proper
tightening torques (2.8 to 3.0 N·m).
4. Always flush the pipe's inside before piping to ensure foreign objects such as machining chips do
not enter the positioner.
5. The actuator opening may become unstable when using the booster relay.
6. Always use a ground connection to prevent noise from the input current and to prevent damage
because of static electricity.
7. Use the pressure reading on the supplied pressure gauge as an indication.
8. The supplied pressure gauge's needle will malfunction if the pressure supply to the internal
mechanism or positioner freezes. Ensure that the pressure gauge's internal parts do not freeze if
using the pressure gauge in an operating environment with an ambient temperature of less than
0°C.
For users
Caution
1. Assemble, operate and maintain the positioners after reading the operation manual tho-roughly
and understanding the content.

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 Suppl
y
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.

1-5 Precautions
Be sure to read before handling.
Maintenance
Warning
1. After installation, repair or disassembly, connect compressed air and conduct tests
to confirm appropriate function and leakage.
Do not use the positioner when noise from the bleeder sounds louder compared with the initial
state, or when it does not operate normally. If these occur, check immediately if assembled and
mounted correctly.
Never modify electrical construction to maintain explosion-proof construction.
Warning-Potential electrostatic charging hazard
1. The non-metallic parts incorporated in the enclosure of this equipment may
generate an ignition capable level of electrostatic charge. Therefore particularly
when it used for applications that specifically require Group IIC, EPL Ga
equipment, the equipment shall not be installed in a location where the external
conditions are conductive to the build-up of electrostatic charge on such surfaces.
Additionally, the equipment shall only be cleaned with a damp cloth.
2. The enclosure contains aluminum and is considered to present a potential risk of
ignition by impact or friction. Care must be taken during installation and use to
prevent impact or friction. Particularly, it must not be used for applications that
specifically require EPL Ga equipment.
Caution
1. The insulation between an intrinsically safe circuit and a frame of the equipment is
not capable of withstanding a 500V dielectric strength test as defined in CI.6.3.12 of
EN 60079-11:2007. This shall be taken into account during installation.
2. the earthing of enclosure is necessary to maintain Intrinsic Safety because the
insulation between an intrinsically safe circuit and a frame of the equipment is not
capable of withstanding a 500V dielectric strength test. There are two earthing
points on the equipment. One is provided as an internal earthing point inside rear
cover of the equipment for attaching of a cable screen. The other is provided as an
external earthing point on the left side of the enclosure. Their cross-sectional areas
should be capable of carrying the maximum possible current of the
equipment.(Generally, an insulated wire having a cross-sectional area of at least
4mm2 is recommended) The cable should be fitted with a spilt ring lock washer to
minimize the risk of self-loosening and is of suitable construction for securing of
conductors of cross sections up to 4mm2.

① Supply air directly to the actuator, adjust the air filter regulator and set air when the valve
reaches to 50% stroke.
② Install the feedback pin at around 30% higher point of the stroke indicated on the feedback
lever than the required stroke of the control valve and fix with a screw tightly. For example,
Control valve stroke Stroke indicated on feedback lever
15mm 15mm
20mm 20mm
30mm 30mm
③ Install the feedback lever horizontally at 50% stroke position.
④ If the feedback lever is not installed horizontally, move the mounting bracket up and down
little by little so that it can be positioned horizontally.
⑤ Fix the mounting bracket with screws (M8).
⑥ Connect air lines between the ASD-7 linear positioner and the actuator and supply air to the
positioner and perform auto-calibration by pushing Mode button for 5 seconds.
⑦ The operating angle from 0% to 100% stroke should be within the range of ±30°. In case of
the over-range of 30°, move the valve stem pin to left or right and make the ASD-7 linear
positioner stay within the operating angle of ±30°.
Make sure that the ASD-7 linear positioner works within the operating range of ±30°.
See the below pictures. Otherwise, the error message of ‘MONT’ appears on LCD and
the auto-calibration process fails. Take action as advised in the above ⑦ and get the
ASD-7 linear positioner feedback lever positioned horizontally at 12mA (50%).
