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.

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.

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.

12. Pay attention to leakage current. <2-wire type> Current (leakage current) flows to the load to operate the internal circuit 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 auto switch if this specification will not be satisfied.

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.

Operating Environment 1. Never use in an atmosphere of explosive gases. The structure of auto switches is not intended to prevent explosion. This may lead to explosion hazard. Contact SMC for information regarding explosion proof compliant product. 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.
■Definition and terminology Term Meaning and definition A type of indicating methods which lights up the Red LED light up when the Auto switch comes 2-color indication to the operating position, and lights up the Green LED when the Auto switch comes to the optimum operating position.
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.

Maintenance After the power has been disconnected, please observe the following precautions:- Regarding the actuator operation set up, the contents of the program may be maintained by the customer's application system. Take care to confirm safety when the power is re-connected, and the actuator operation is resumed, because the operation may have stopped in an unstable condition.
Troubleshooting When the Auto switch falls in operation failure, identify the trouble with the following flow chart. A failure of the Auto switch might depend on operating environment (application etc.) and needs to be given a measure by contacting to us separately.
