3.8.2.2 Wiring
• When connecting to the terminals via insulating tube and M3.5 crimp
terminals, arrange the crimp terminals as shown below so that they do
not rise up onto the case or the cover. Application lead wire size:
AWG20 to AWG18 (0.5 to 0.75 mm²)
Figure 19.
• Do not push crimp terminals into gaps in the case interior. Doing so
may cause damage or deformation of the case.
• Use crimp terminals not more than 0.5 mm in thickness. Otherwise,
they will interfere with other components inside the case. The crimp
terminal shown below are not more than 0.5 mm thick.

3.8.2.3 Conduit opening
• Connect a recommended connector to the opening of the conduit and
tighten the connector to the specified torque. The case may be
damaged if an excessive tightening torque is applied.
• Use a cable with a suitable diameter for the connector.
3.8.2.4 Recommended connectors
• Use connectors with screws not exceeding 9 mm, otherwise the
screws will protrude into the case interior, interfering with other
components in the case. The connectors listed in the following table
have connectors with thread sections not exceeding 9 mm. Use the
recommended connectors to ensure conformance to the stated IP
level.

3.8.4.1 Socket tightening
• Turn the socket connector screws by hand and tighten until no space
remains between the socket and the plug.
• Make sure that the socket connector is tightened securely. Otherwise,
the rated degree of protection may not be maintained and vibration
may loosen the socket connector.
• Orientation of the M12 connector is not guaranteed. Only a straight
connector should be used.

6 Maintenance
6.1 General maintenance
Caution
• Not following proper maintenance procedures could cause the product
to malfunction and lead to equipment damage.
• If handled improperly, compressed air can be dangerous.
• Maintenance of pneumatic systems should be performed only by
qualified personnel.
6 Maintenance - continued
• Before performing maintenance, turn off the power supply and be sure
Applicable
Model
to cut off the supply pressure. Confirm that the air is released to
cable diameter
6.0 to 12.0 mm
atmosphere.
• After installation and maintenance, apply operating pressure and
7.0 to 9.0 mm
power to the equipment and perform appropriate functional and
9.0 to 11.0 mm
leakage tests to make sure the equipment is installed correctly.
• If any electrical connections are disturbed during maintenance, ensure
they are reconnected correctly and safety checks are carried out as
required to ensure continued compliance with applicable national
regulations.
• Do not make any modification to the product.
• Do not disassemble the product, unless required by installation or
maintenance instructions.
6.2 Maintainable parts
• Under no circumstances attempt to change the solenoid of the pilot
valve as this is an integral part of the valve and doing so will invalidate
SMC warranty.
• There are no replaceable parts on these safety products.
6.3 Periodic testing
• The product should be tested for proper operation of the safety function
once per month or whenever considered necessary for the purposes
of the end user. The test should consist of operation of the safety
system and observation of the following:
When the connected control system is energising the solenoids:
• Check that the solenoid indicator lights are illuminated.
• Check that the connected downstream system is properly
pressurised.
• Check that the switch contacts are open.
• For duplex valve assemblies check that when only one channel of
the system (one of the solenoids) is energised the protected system
does not become pressurised. Check this for both channels.
When the connected control system is not energising the solenoids:
• Check that the solenoid indicator lights are not illuminated.
• Check that the connected downstream system is properly vented to
atmosphere and ensure that the condition of the silencers is not
causing an extension of the vent time.
• Check that the switch contacts are closed.
• For the duplex valve assemblies check that when only one channel
of the system (one of the solenoids) is de-energised the protected
system is vented to atmosphere. Check this for both channels.
The specification of the valve requires the valve to be cycled (energised
and de-energised) at least once per week.
6.4 Silencers
• Ensure that any silencers fitted to the valve remain clean and
uncontaminated in operation because blockage will affect the safety
function.
• Examine any silencers at least once per month and more frequently if
necessary due to the nature of the application environment.
