2. CAUTION

2.1 Fluid

1) Use the compressed air,filtrated and

dehumidified. Carefully select a filter

of an adequate filtration rate (5μm or

lower preferred), flow rate and its

mounting location (asclosest to direc-

tional control valve as possible)

2) Be sure to drain out the accumulation

in filter periodically.

3) Note that the intrusion of carbide of

compressor oil (such as carbon or tarry

substance) into the circuit causes

malfunction of solenoid valve and cyl-

inder.Be sure to carry out thorough

inspection and maintenance of com-

pressor.

3. OPERATION

Setting the cylinder speed

Turning the handle ①clockwise re-

duces the speed of cylinder,finally

closing the controller,while turning it

counterclockwise increases the speed

of cylinder.Tobuild ameter out cir-

cuit, close the controller first by turn-

ing its handle ①clockwise, then con-

nect it to the piping so that the casted

JIS symbol on the body ③matches

with the direction of flow as per des-

igned schematic.

While giving pressure to the circuit, turn the handle ①of controller

counterclockwise until the required speed of the cylinder is set. Once the

position of the handle ①is set, make sure to tighten up the lock nut ②.

Note :

The cylinder will no longer gain its speed after the handle ①is turned ap-

prox. 8 to 10 times from the fully closed position as the controller gets out

of the controllable range of speed.

4. INSTALLATION

4.1 Piping

1) For piping beyond the filter, use pipes that are tough against corrosion such

as galvanized pipes, nylon tubes, rubber tubes, etc. (Refer to Selection

Guide Table for Related Equipment.)

2) See to it that the pipe connecting cylinder and solenoid valve has effective

sectional area which is needed for the cylinder to drive at the specified speed.

(Refer to Selection Guide Table for Related Equipment.)

3) Install filterpreferably adjacent to the

upper-stream to the solenoid valve for

eliminating rust, foreign substance in

the drain of the pipe.

4) Be sure observe the effective thread

length of gas pipe and give achamger

of approx. 1/2 pitch from the threaded

end.

5) Flush air into the pipe to blow out for-

eign substances and chips before piping.

6) Refrain from mapplying sealant or sealing tape approx. two pitches of thread

off the tip of pipe to avoid residual substances from falling into piping sys-

tem.

5. MAINTENANCE

5.1 Trouble shootig

Trouble Causes Remedies

1. The controller is installed in

the erroneous direction per

specified on the schematics.

Reaffirmthe direction of flow and

correct it if found the connection is

incorrect.

Turning the handle of control-

ler does not influence to the

speed of cylinder 2. Foreign particle is caught by

packing Blow away the foreign particle by

means of air flushing.
