Warning
• 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. The expected performance and safety
assurance of the equipment will be the responsibility of the person who has
determined its compatibility with the product. This person should also
continuously review all specifications of the product referring to its latest
catalogue information, with a view to giving due consideration to any
possibility of equipment failure when configuring the equipment.
• Only personnel with appropriate training should operate machinery
and equipment.
The product specified here may become unsafe if handled incorrectly.
The assembly, operation and maintenance of machines or equipment
including our products must be performed by an operator who is
appropriately trained and experienced.
• Do not service or attempt to remove product and machinery/
equipment until safety is confirmed.
1) The inspection and maintenance of machinery/equipment should only
be performed after measures to prevent falling or runaway of the driven
objects have been confirmed.
2) When the product is to be removed, confirm the safety measures as
mentioned above are implemented and the power from any appropriate
source is cut, and read and understand the specific product precautions of
all relevant products carefully.
3) Before machinery/equipment is restarted, take measures to prevent
unexpected operation and malfunction.
• Do not use this product outside of the specifications.
• Contact SMC beforehand and take special consideration of safety
measures if the product is to be used in any of the following
conditions.
1) Conditions and environments outside of the given specifications or use
outdoors or in a place exposed to direct sunlight.
2) Installation on equipment in conjunction with atomic energy, railways,
air navigation, space, shipping, vehicles, military, medical treatment,
combustions and recreation, or equipment in contact with food or
beverages, emergency stop circuits, clutch and brake circuits in press
applications, safety equipment or other applications unsuitable for the
specification described in this document.
3) An application which could have negative effects on people, property or
animals requiring special safety analysis outside the scope of EN ISO
13849 described in this document.
4) Use in an interlock circuit, which requires the provision of double
interlock for possible failure by using a mechanical protective function, and
periodical checks to confirm proper operation.
• Always ensure compliance with relevant safety laws and standards.
• All electrical work must be carried out in a safe manner by a qualified
person in compliance with applicable national regulations.
Caution
• The product is provided for use in manufacturing industries.
This product must not be used in residential areas.
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.
Warning
Always ensure compliance with relevant safety laws and standards.
All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.

The switch is connecting pin 1 and 2 in the safe state.
2.2 Safe and unsafe state
The de-energized air operated pilot valve (safe state) enables the air flow for
the safely limited speed of the actuator and the switch is connecting pin 1 and
2. The energized air operated pilot valve (unsafe state) enables the air flow
for the operating speed of the actuator and the switch is connecting pin 1 and
4. The switch is activated by positive mechanical action from "safe state" to
"unsafe state".
The valve spool is spring/air returned. A malfunction of the valve spool non-
returning into the safe state will be detected by the PLC according to the
signal of the switch.
