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 We develop, design, and manufacture our products to be used for automatic control equipment, and provide them for peaceful use in manufacturing industries. Use in non-manufacturing industries is not covered. Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the Measurement Act.
- Page 5 Operator ♦This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. ♦Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product.
- Page 6 Cylinders or actuators include cylinders, air grippers, rotary actuators, and electrical actuators/cylinders. Design/Selection 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. 2.
- Page 7 12. Pay attention to leakage current. Leakage current flow to the load will be “n” times larger when “n” auto switches are connected in parallel. 13. Output operation of the solid state auto switch is not stable for 50 [ms] after powered ON. In the output operation immediately after powered ON or AND connection operation, the input device (PLC or relay, etc.) may judge the ON position as OFF output or the OFF position as ON output.
- Page 8 Wiring 1. Confirm proper insulation of wiring. If there is any improper insulation (mixed contact with other circuit, grounding fault, or improper insulation between terminals, etc.) in the wiring, an over-current flows in, causing the auto switch to break. 2. Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit with these lines.
- Page 9 Operating Environment 1. Never use in an atmosphere of explosive gases, dust. The structure of auto switches is not intended to prevent explosion. This may lead to explosion hazard. 2. Do not use in an area where a magnetic field is generated. Auto switches will malfunction or magnets inside cylinders/ actuators will become demagnetized.

Page 12: Mounting And Installation
Mounting and Installation ■Installation When mounting the Auto switch to the actuator, the appropriate mounting bracket should be used. "How to mount" depends on the actuator type and bore size. Please refer to the actuator catalogue. For new Auto switch applications, confirm that the actuator includes a magnet before assembling the Auto switch and bracket. -
