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 Warning 1. The compatibility of the product is the responsibility of the person who designs the equipment or decides its specifications. Since the product specified here is used under various operating conditions, its compatibility with specific equipment must be decided by the person who designs the equipment or decides its specifications based on necessary analysis and test results.
- Page 5 Limited warranty and Disclaimer 1.The warranty period of the product is 1 year in service or 1.5 years after the product is delivered, whichever is first. Also, the product may have specified durability, running distance or replacement parts. Please consult your nearest sales branch. 2.
- Page 6 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 7 12. Ensure the load energy 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.
- Page 8 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 9 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 10 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 11 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 12 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 table material. 2. Do not expose the product to direct sunlight for an extended period of time. 3.
- Page 13 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 14 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 15 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 16 6. Check the actual actuation status and adjust the auto switch mounting position. According to the installation environment, the rotary table 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 17 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 (－). ［For D-97,(+) is on the no-displayed side,(-) is on the black line side.］ 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 18 6. Do not use in an area where surges are generated. <Solid state> If there is an equipment unit (electromagnetic lifter, high-frequency induction furnace, motor, or radio, etc.) that generates large surges or electromagnetic waves around cylinders with solid state auto switches or actuators, this may cause the circuit element inside the auto switch to break.
