5-Port Solenoid Valves Precautions 4
Be sure to read this before handling products.
Operating Environment
1.
Do not use in an atmosphere containing corrosive
gases, chemicals, sea water, water, water steam, or
where there is direct contact with any of these.
2.
Products with IP67 enclosures (based on IEC60529)
are protected against dust and water. However, these
products cannot be used in water.
3.
Products compliant with IP67 satisfy the product
specifications when mounted properly. Be sure to
read the precautions for each product.
4.
Do not use in an environment where flammable gas
or explosive gas exists. Usage may cause a fire or
explosion. The products do not have an explosion
proof construction.
5.
Do not use in a place subject to heavy vibration
and/or shock.
6.
The valve should not be exposed to prolonged
sunlight. Use a protective cover. Note that the valve
is not for outdoor use.
7.
Remove any sources of excessive heat.
8.
If it is used in an environment where there is possible
contact with oil, weld spatter, etc., exercise
preventive measures.
9.
When the solenoid valve is mounted in a control panel
or it's energized for a long period of time, make sure
the ambient temperature is within the specifications of
the valve.
1.
Temperature of ambient environment
Use the valve within the range of the ambient temperature
specification of each valve. In addition, pay attention when using
the valve in environments where the temperature changes
drastically.
2.
Humidity of ambient environment
•
When using the valve in environments with low humidity, take
measures to prevent static.
• If the humidity rises, take measures to prevent the adhesion of
water droplets on the valve.
1.
Perform maintenance and inspection according to
the procedures indicated in the operation manual.
If handled improperly, human injury and/or malfunction or
damage of machinery and equipment may occur.
2.
Removal of equipment, and supply/exhaust of
compressed air
Before components are removed, first confirm that measures
are in place to prevent workpieces from dropping, run-away
equipment, etc. Then, cut off the supply air and electric power,
and exhaust all air pressure from the system using the residual
pressure release function.
When the equipment is operated after remounting or
replacement, first confirm that measures are in place to prevent
the lurching of actuators, etc. Then, confirm that the equipment
is operating normally.
3.
Low-frequency operation
Valves should be operated at least once every 30 days to
prevent malfunction. (Use caution regarding the air supply.)
4.
Manual override
When a manual override is operated, connected equipment will
be actuated.
Operate only after safety is confirmed.
5.
If the volume of air leakage increases or the valve
does not operate normally, do not use the valve.
Perform periodic maintenance on the valve to
confirm the operating condition and check for any air
leakage.
1.
Drain flushing
Remove drainage from the air filters regularly.
2.
Lubrication
In the case of rubber seals, once lubrication has been started, it
must be continued.
Use class 1 turbine oil (with no additives), VG32. If other
lubricant oil is used, it may cause a malfunction. Please contact
SMC for information on the suggested class 2 turbine oil (with
additives), VG32.
