Implement countermeasures to avoid any danger that may occur due to the actuator’s operation. 3.2 EnvironmentWarning• Do not use in an environment where corrosive gases, chemicals, salt water or steam are present.• Do not use in an explosive atmosphere.• Do not expose to direct sunlight. Use a suitable protective cover.• Do not install in a location subject to vibration or impact. Check the product specifications.• Do not mount in a location exposed to radiant heat.• Products with IP65 and IP67 enclosures (based on IEC60529) are protected against dust and water; however, these products cannot be used in water.• Products compliant to IP65 and IP67 satisfy the specifications by mounting the product appropriately. Be sure to read the Specific Product Precautions for each product.• When using built-in silencer type manifold with an IP65 or IP67 enclosure, keep the exhaust port of the silencer from coming in directcontact with water or other liquids.• The metal seal valve is provided with a hole to discharge the pilot EXH. When using in atmospheres containing water and dust, mount horizontally.• Do not use in high humidity environment where condensation can occur.• If using in an atmosphere where there is possible contact with water drop-lets, oil, weld spatter, etc., take suitable preventive measures. • When the solenoid valve is mounted in a control panel or it is energized for a long time, make sure that the ambient temperature is within the specification of the valve. •Contact SMC for altitude limitations.3.3 PipingCaution• Before piping make sure to clean up chips, cutting oil, dust etc.• When installing piping or fittings, ensure sealant material does not enter inside the port. When using seal tape, leave 1 thread exposed on the end of the pipe/fitting.• Tighten fittings to the specified tightening torque.3.4 LubricationCaution• SMC products have been lubricated for life at manufacture, and do not require lubrication in service.• If a lubricant is used in the system, refer to catalogue for details. 3.5 One-touch fittings3.5.1 Tube attachment and detachmentCautionRefer to the Specific Precautions in the catalogue.3.6 Precautions on other tube brandsCautionWhen using non-SMC brand tubes, refer to the Specific Precautions in the catalogue.3.7 Indicator Light/Surge Voltage SuppressorIf a valve type without suppression is used, suppression should be provided as close as possible to the valve by the host controller. 3.8 Polarity Surge voltage suppressor (□S)Surge voltage suppressor (□S)Positive common Double solenoid, 3-position, 4-position Negative common Double solenoid, 3-position, 4-positionSurge voltage suppressor (□S)Surge voltage suppressor (□NS)Figure 13.8.2 Non-polar typeWith surge voltage suppressor (□R)Single solenoidDouble solenoidORIGINAL INSTRUCTIONSPolarity protection diodePolarity protection diodePolarity protection diodePolarity protection diodePolarity protection diodePolarity protection diodePolarity protection diodePolarity protection diodeCoil CoilCoil CoilCoil CoilCoilCoil Coil CoilCoilCoilCoilCoilVaristorVaristorVaristor(Green) (Green) (Orange)(Orange)Figure 23.9 With power saving circuitPower consumption is decreased by approximately 1/3rd by reducingthe wattage required to hold the valve in an energized state.(Effective energizing time is over 67 ms at 24 VDC).*Be careful of the energizing time, as quick response and high pressuretypes will become operational when the energizing time is over 40 ms.Standard High pressureFigure 3•The above circuit reduces the power consumption for holding in orderto save energy. Refer to the catalogue for details.•The 12 VDC specification with power saving circuit (standardspecification) does not have the polarity protection diode. Do notmake a mistake with the polarity.•Since the voltage will drop by approx. 0.5 V due to the transistor, payattention to the allowable voltage fluctuation. (For details, refer to thesolenoid specifications of each type of valve.)3.10 Residual VoltageCaution•If a varistor or diode surge voltage suppressor is used, thesuppressor arrests the back EMF voltage from the coil to the levelindicated in Table 7. Ensure the transient voltage is within thespecification of the host controller.•Valve response time is dependent on surge suppression method3.11 Countermeasure for surge voltageCautionAt times of sudden interruption of the power supply, the energy storedin a large inductive device may cause non-polar type valves in a de-energised state to switch.When installing a breaker circuit to isolate the power, consider a valvewith polarity (with polarity protection diode), or install a surge absorptiondiode across the output of the breaker.WarningIf a valve is energized continuously for a long period of time, the rise intemperature due to heating-up of the coil assembly may cause adecline in solenoid valve performance, reduce service life, or haveadverse effects on peripheral equipment.If the valve is energized continuously for a long period of time, be sureto use a valve with power saving circuit. In particular, if three or moreadjacent stations on the manifold are energized simultaneously forextended periods of time or if the valves on A side and B side areenergized simultaneously for a long period of time, take special care asthe temperature rise will be greater.3.13 Momentary energizationCautionIf a double solenoid valve will be operated with momentary energization,it should be energized for at least 0.1 second. However, depending onthe secondary load conditions, it should be energized until the cylinderreaches the stroke end position, as there is a possibility of malfunctionotherwise.3.14 Light IndicationWhen equipped with indicator light and surge voltage suppressor, thelight window turns orange when solenoid ‘a’ is energized, and it turnsgreen when solenoid ‘b’ is energized.Figure 43.15 Valve MountingCaution•Mount the valve so that there is no slippage or deformation in gaskets•Refer to catalogue for other screw torque values.3.16 Manual overrideWarningRegardless of an electric signal for the valve, the manual override isused for switching the main valve. Connected actuator is started bymanual operation. Only use the manual override after confirming thatthere is no danger.WarningLocked manual overrides might prevent the valve responding to beingelectrically de-energised or cause unexpected movement in theequipment.Refer to the catalogue for details of manual override operation.3.17 Changing Connector Entry DirectionCautionRefer to the Specific Product Precautions in the catalogue.3.18 Reverse flowCautionOnly the external pilot variants are suitable for reverse flow withpressure supplied on ports 3 and 5 provided the pressure is less than0.7 MPa. Reverse flow cannot be applied to 'H' variants with built incheck-valves or valves fitted with SY#0M-24-1A check valves.3.19 Back pressure check valvesBack pressure from the common manifold exhausts can be preventedfrom affecting actuators connected to ports 2 and 4 by using the ‘H’variant valve or fitting SY#0M-24-1A check valves.The flow capacity of the valve is reduced in these cases.See catalogue for full details on back pressure check valves.3.20 Effect of back pressure when using a manifoldWarningUse caution when valves are used on a manifold, because an actuatormay malfunction due to back-pressure.For 3-position exhaust centre valve or single acting cylinder, takeappropriate measures to prevent malfunction by using it with anindividual EXH interface block or an individual exhaust manifold.3.21 External pilot exhaustsCautionThe external pilot variants use the manifold PE connection for pilotexhaust. Ensure that this connection is always vented to atmosphereand not subject to any pressure pulses from other devices.3.22 Change of piping types between Top and Side, port blockwhile mounted on a manifold and one-touch fittingsCautionRefer to the Specific Product Precautions in the catalogue.3.23 One-touch FittingsCautionWhen fittings are used, they may interfere with one another dependingon their types and sizes.
