7 Maintenance
7.1 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.
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 electricalconnections are disturbed duringmaintenance, 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.
7.2 Mounting Danger
Never add or remove a valve from the manifold when energised.
Never remove terminal box cover when power is connected to the
manifold.
Never disconnect or reconnect cables or connectors when power is
connected to the valves. Caution
Be sure to cut off power and the air supply and confirm that no air is
left in actuators, piping and manifolds before disassembling, as
remaining air may cause an accident.
Before assembly and installations, confirm that rubber parts such as
gaskets and O rings are assembled to every block. If rubber parts are
missing, air leakage may occur.
Manifold 50-VFE-X60:
Removal of valve
Remove screws and gently lift valve from manifold.
Ensure gasket and spacer are not misplaced or damaged.
Disconnect electrical connection.
7 Maintenance - continued
Assembly of valve
