Page 3: Safety Instructions
Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations. - Page 4 Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
- Page 5 Design / Selection Warning 1. Confirm the specifications. Products represented in this catalog are designed only for use in compressed air systems. Do not operate at pressures or temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction. (Refer to the specifications.) Please contact SMC when using a fluid other than compressed air.
- Page 6 12. Select a speed within the product’s allowable energy value. If the product’s kinetic energy of the load exceeds the allowable value, it could damage the product, and cause a hazard to humans and damage the machinery and equipment. 13. Provide a shock absorber if the kinetic energy that is applied to the product exceeds the allowable value.
- Page 7 Mounting Warning 1. Operation manual Install the product and operate it only after reading the operation manual carefully and understanding its contents. Also, keep the manual in a location where it can be referred to as necessary. 2. Ensure sufficient space for maintenance activities. When installing the products, allow access for maintenance.
- Page 8 12. Place an external stopper in a position that is away from the rotating table. If the stopper is placed near the rotating table, the torque that is generated by the product itself will cause the reaction force which is directed to the stopper to be redirected and applied to the rotating table. This will lead to the breakage of the rotating table and bearing.
- Page 9 Caution 1. Do not use organic solvent to wipe the area of the name plate that shows the model. It will erase what is indicated on the name plate. 2. Do not hit the rotating table by securing the body or hit the body by securing the rotating table.
- Page 10 Lubrication Warning 1. This product should be used without lubrication. Although it will operate even if it is lubricated, it could lead to sticking or slipping. Air Supply Warning 1. Type of fluids Please consult with SMC when using the product in applications other than compressed air. 2.
- Page 11 Operating Environment Warning 1. Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, steam, or where there is direct contact with any of these. Refer to the construction for information on the rotary actuator material. 2. Do not expose the product to direct sunlight for an extended period of time. 3.
- Page 12 Auto Switches Precautions Design / Selectio Warning 1. Confirm the specifications. If the product is used with excess load applied or beyond the specification range, this may cause the product to break or malfunction. We do not guarantee against any damage if the product is used outside of the specification range.
- Page 13 8. Keep wiring as short as possible. <Reed> As the length of the wiring to a load gets longer, the rush current at switching ON becomes greater, and this may shorten the product’s life. (The switch will stay ON all the time.) 1) Use a contact protection box when the wire length is 5m or longer.
- Page 14 11. Pay attention to leakage current. <2-wire type> Current (leakage current) flows to the load to operate the internal circuit even when in the OFF state. > Operating current of load (OFF condition) Leakage current If the criteria given in the above formula are not met, it will not reset correctly (stays ON).Use a 3-wire switch if this specification will not be satisfied.
- Page 15 6. Check the actual actuation status and adjust the auto switch mounting position. According to the installation environment, the rotary actuator may not operate even at its proper mounting position. Even when setting at a midpoint of the stroke, check the actuation status and make the adjustment in the same manner.
- Page 16 7. Avoid incorrect wiring. <Reed> A 24 VDC auto switch with indicator light has polarity. The brown lead wire or terminal No.1 is (+), and the blue lead wire or terminal No.2 is (－). 1) If connections are reversed, an auto switch will operate, however, the light emitting diode will not light Also, take note that a current greater than that specified will damage a light emitting diode and it will no longer operate.
- Page 17 2. Do not use in an environment where the auto switch will be continually exposed to water. Although auto switches satisfy IEC standard IP67 construction expect some models (D-A3□, A44□, G39□, K39□, RNK, RPK) do not use auto switches in applications where continually exposed to water splash or splay.
- Page 18 Caution 1. Perform the following maintenance periodically in order to prevent possible danger due to unexpected auto switch malfunction. 1) Secure and tighten auto switch mounting screws. If screws become loose or the mounting, position is dislocated, retighten them after readjusting the mounting position.

Page 27: Setting Of Rotation Time
Setting of rotation time It is necessary to calculate the inertial load and kinetic energy in the application prior to setting the speed of the actuator. The inertial load generated in the application may be high even if the torque required in the application is low, this may lead to damage to the internal components of the actuator. -

Page 32: Maintenance And Inspection
Maintenance and Inspection Periodic inspection is necessary for optimum use. Generally, annual inspection is recommended for the rotary actuator. Even if no problem is found, seal parts replacement is recommended every three years. It is highly possible that the actuator is operated out of specification when the components like pinion, piston, bearing are broken. - Page 33 ■Disassembly procedure （1）Loosen cross recessed no.0 screw（size 10,15）or roundhead screw（size 20,30,40）. （2）Pull out the bearing retainer and the shaft from the body. Remove the bearing from the housing at this time. （3）Loosen hexagon socket head bolt to remove the cover assembly and the end cover assembly. （4）Push piston assembly from one side to pull out two piston assembly from the body.
