6 Maintenance - continued
•
Maintenance of pneumatic systems should be performed only by
qualified personnel.
•
Before performing maintenance, turn off the power supply and be sure
to cut off the supply pressure. Confirm that the air is released to
atmosphere.
•
After installation and maintenance, apply operating pressure and
power to the equipment and perform appropriate functional and
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 Replacement parts
Refer to catalogue for replacement parts.
6.3 Addition and removal of manifold stations
Refer to catalogue for additional information.
7 Limitations of Use
7.1 Limited warranty and disclaimer/compliance requirements
Refer to Handling Precautions for SMC Products.
Warning
7.2 Return of the valve to the de-energised position
When electricity is cut, the valve returns to the de-energised position by
spring force.
7.3 Holding of pressure
Since valves are subject to air leakage, they cannot be used for
applications such as holding pressure (including vacuum) in a system.
7.4 Cannot be used as an emergency shut-off valve
This product is not designed for safety applications such as an
emergency shut-off valve. If the valves are used in this type of system,
other reliable safety assurance measures should be adopted.
Caution
7.5 Leakage voltage
Ensure that any leakage voltage caused by the leakage current when the
switching element is OFF causes ≤ 2% of rated voltage across the valve.
7.6 Low temperature operation
Unless otherwise indicated in the specifications for each valve, operation
is possible to -
10˚C, but appropriate measures should be taken to avoid
solidification or freezing of drainage and moisture, etc.
7.7 Vacuum release application
•
Use 3 (R) port for vacuum pressure and 1 (P) port for vacuum release
pressure.
•
Set the pressure so that the pressure difference between the 3(R) and
1(P) ports does not exceed the maximum operating pressure of the
valve.
•
When the 3(R) port is used for the vacuum release (atmospheric
pressure to positive pressure) and the 1(P) port is used for the vacuum,
use the normally open (N.O.) specifications.
