1 Safety Instructions - continued
• 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.
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.
2 Specifications
Warning
Special products (-X) might have specifications different from those
shown in this Instruction Manual. Contact SMC for specific drawings.
2.1 Functional description
The product consists of either one or two solenoid operated 2 position 3
port valves, which are connected to a main air supply (in some cases via
an integrated soft-start valve). The valves are capable of performing the
safety function described in this document. The soft start valve is
intended to allow the end user to perform machine operational start up
procedures with reduced flow potential until a pre-set operational
pressure is achieved. At the defined pressure the soft start valve allows
full flow in order to achieve full operation. The soft start function is
intended for machine operation purposes and not for the performance of
a safety function.
