6. MAINTENANCE
6.1 Periodic Inspection
Before providing a maintenance service, cut the power
and the supply of compressed air and confirm the ab-
sence of residual pressure.
The above is required to ensure safety.
Regularly perform the daily and periodic inspections to
correctly maintain product performance.
If the product is not correctly maintained , product per-
formance may deteriorate dramatically, resulting in a
shorter service life, fractures of components, and mal-
functions.
1) To use the solenoid valve system under optimum conditions, perform a peri-
odic inspection once or twice a year.
2) Check the screws for loosening and the joints in the piping for integrity of the
sealing.
Regularly remove the drain from the air filters.
(1) Checking the compressed air supply pressure:
Is the supply pressure at the specified level?
Does the pressure gauge indicate the specified pressure when the system is
operating?
(2) Checking the air filters:
Is the drain normally discharged?
Is the amount of dirt attached to the bowl and element at a normal level?
(3) Checking joints in the piping for the leakage of compressed air:
Are the pipes normally connected at joints, especially at the movable parts?
(4) Checking the operation of solenoid valves:
Is not there any delay in the operation? Is the exhaust flow normal?
(5) Checking the operation of pneumatic actuators:
Is the operation smooth?
Does the actuator stop normally at the end of the stroke?
Is the coupling with the load normal?
(6) Checking the lubricator:
Is the amount of oil adjusted properly?
(7) Checking the lubrication oil:
Is the supplied lubrication oil of the type specified by the manufacturer?
