Operating Environment
1. Do not use in an atmosphere having corrosive
gases, chemicals, sea water, water, water steam,
or where there is direct contact with any of
these.
2. 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.
3. Do not use in a place subject to heavy vibration
and/or shock.
4. The valve should not be exposed to prolonged
sunlight. Use a protective cover.
5. Remove any sources of excessive heat.
6. If it is used in an environment where there is
possible contact with oil, weld spatter, etc.,
exercise preventive measures.
7. When the solenoid valve is mounted in a control
panel or its energized for a long time, make sure
ambient temperatures is within the specification
of the valve.
Maintenance
1. Perform maintenance inspection according to
the procedures indicated in the operation
manual.
If handled Improperly, malfunction and damage of
machinery or equipment may occur.
2. Removal of equipment, and supply / exhaust of
compressed air
When components are removed, first confirm that
measures are in place to prevent workpieces from dropping,
run-away equipment, etc. Then, cut off the supply pressure
and electric power, and exhaust all compressed air 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 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 the manual override is operated, equipment will be
actuated.
Operate after safety is confirmed.
1. Drain flushing
Remove drainage from the air filters regularly.
2. Lubrication
Once lubrication has been started, it must be continued.
Use class 1 turbine oil (with no additive), ISO VG32
because if other lubricant oil is used, it may cause
malfunction. Please contact SMC for suggested class 2
turbine oil (with additive), ISO VG32.
