Enhanced locking efficiencyGreater locking efficiency as well as stable locking and

unlocking operation has been achieved by arranging a

large number of steel ball bearings in circular rows. The

floating taper ring provides alignment and stable locking

force with respect to piston rod eccentricity. (Unlocking

pressure of 0.25MPa ...... 0.05MPa lower than

conventional SMC products)

Simple constructionA force magnifying mechanism is employed based on the wedge effect of a taper ring and steel balls.

Greater reliability and stable holding force

A metal rod scraper is standardResistance against welding process spatter and other external contaminants is achieved by providing a metal rod scraper as standard.

Outstanding durability and stable

holding force are maintained through

the use of a substantially lengthened

brake shoe which provides superior

wear resistance. (Double that of a

conventional SMC product)

Bore size(mm)

Maximum piston speed: 500mm/sWithin the allowable kinetic energy range, speeds between 50 to 500mm/s can be achieved.

Simple manual overrideIn the event that the air supply is cut off or unavailable, unlocking can be performed with a commercially available tool. The fail safe mechanism locks again when the manual override is released.

Enclosed construction minimizes influences of poor air quality Separation of the lock mechanism and the unlocking

piston chamber produces a structure which is

resistant to moisture and drainage in compressed air.

Compact lock unit saves spaceThe lock unit is extremely compact, without a large overhang.

Can be locked in bothdirectionsHolding force is equal on either extend or retract.

Spring Locking (Exhaust Locking) The spring force which acts upon the taper ring is magnified by a wedge effect, and is conveyed to all of the numerous steel balls which are arranged in two circles. These act on the brake shoe holder and brake, which locks the piston rod by tightening against it with a large force.Unlocking is accomplished when air pressure is supplied to the unlocking port. The release piston and taper ring oppose the spring force, moving to the right side, and the ball retainer strikes the cover section A. The braking force is released as the steel balls are removed from the taper ring by the ball retainer.

1. In order that the originally selected maximum speed is not exceeded, be certain to use a speed controller to adjust the total movement distance of the load so that movement takes place in no less than the applicable movement time.The movement time is the time that is necessary for the load to travel the total movement distance from the start without any intermediate stops.

2. In cases where the cylinder stroke and the movement distance of the load are different (double speed mechanism, etc.), use the movement distance of the load for selection purposes.

Find the maximum load speed: V

Selection Example

Caution

Example)

• Load weight: m = 320kg• Movement distance: st = 400mm• Movement time: t = 2s• Load condition: Vertical downward = Load in direction of rod extension • Operating pressure: P = 0.4MPa

Step 1: From graph 1 find the maximum movement speed of the load

∴ Maximum speed V: approx. 280mm/s

Step 2: Select Graph 6 based upon the load condition and operating pressure, and then from the intersection of the maximum speed V = 280mm/s found in Step 1, and the load weight m = 320kg

∴ ø140→ select a CNS140 or larger bore size.

Find the maximum load speed: V(mm/s) from the load movement time: t(s) and the movement distance: st(mm).

Find the cylinder bore size.

Safety Instructions

Note 1) ISO 4414: Pneumatic fluid power -- Recommendations for the application of equipment to transmission and control systems.

Note 2) JIS B 8370: Pneumatic system axiom.

Warning

Caution : Operator error could result in injury or equipment damage.

Warning : Operator error could result in serious injury or loss of life.

Danger : In extreme conditions, there is a possible result of serious injury or loss of life.

These safety instructions are intended to prevent a hazardous situation and/or equipment damage. These instructions indicate the level of potential hazard by a label of "Caution", "Warning" or "Danger". To ensure safety, be sure to observe ISO 4414 Note 1), JIS B 8370 Note 2) and other safety practices.

1 The compatibility of pneumatic equipment is the responsibility of the person who designs the pneumatic system or decides its specifications.Since the products specified here are used in various operating conditions, their compatibility for the specific pneumatic system must be based on specifications or after analysis and/or tests to meet your specific requirements.

2 Only trained personnel should operate pneumatically operated machinery and equipment.Compressed air can be dangerous if an operator is unfamiliar with it. Assembly, handling or repair of pneumatic systems should be performed by trained and experienced operators.

3 Do not service machinery/equipment or attempt to remove components until safety is confirmed.

1.Inspection and maintenance of machinery/equipment should only be performed after confirmation of safe locked-out control positions.

2.When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply pressure for this equipment and exhaust all residual compressed air in the system.

3.Before machinery/equipment is re-started, take measures to prevent shooting-out of cylinder piston rod, etc. (Bleed air into the system gradually to create back-pressure.)

4 Contact SMC if the product is to be used in any of the following conditions:1.Conditions and environments beyond the given specifications, or if product is used outdoors.2.Installation on equipment in conjuction with atomic energy, railway, air navigation, vehicles, medical

equipment, food and beverages, recreation equipment, emergency stop circuits, press applications, or safety equipment.

3.An application which has the possibility of having negative effects on people, property, or animals, requiring special safety analysis.

21

Mounting

1. There is a possibility of dangerous sudden action by air cylinders if sliding parts of machinery are twisted due to external forces, etc.In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be designed to avoid such dangers.

2. A protective cover is recommended to minimize the risk of personal injury.If a stationary object and moving parts of a cylinder are in close proximity, personal injury may occur. Design the structure to avoid contact with the human body.

3. Securely tighten all stationary parts and connected parts so that they will not become loose.When a cylinder operates with high frequency or a cylinder is installed where there is a lot of vibration, ensure that all parts remain secure.

4. A deceleration circuit or shock absorber, etc., may be required.When a driven object is operated at high speed or the load is heavy, a cylinder's cushion will not be sufficient to absorb the shock. Install a deceleration circuit to reduce the speed before cushioning, or install an external shock absorber to relieve the shock. In this case, the rigidity of the machinery should also be examined.

5. Consider emergency stops.Design so that human injury and/or damage to machinery and equipment will not be caused when machinery is stopped by a safety device under abnormal conditions, a power outage or a manual emergency stop.

6. Consider the action when operation is restarted after an emergency stop or abnormal stop.Design the machinery so that human injury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install manual safety equipment.

1. Check the specifications.The products advertised in this catalog are designed according to use in industrial compressed air systems. If the products are used in conditions where pressure, temperature, etc., are out of specification, damage and/or malfunction may be caused. Do not use in these conditions.

Consult SMC if you use a fluid other than compressed air.

SelectionPrecautions on Design

1. Operate within the limits of the maximum usable stroke.The piston rod will be damaged if operated beyond the maximum stroke.

2. Operate the piston within a range such that collision damage will not occur at the stroke end.Operate within a range such that damage will not occur when the piston having inertial force stops by striking the cover at the stroke end. Refer to the cylinder model selection procedure for the range within which damage will not occur.

3. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting.

4. Provide an intermediate support for cylinders having a long stroke length.An intermediate support should be provided in order to prevent damage in cylinders having a long stroke, due to problems such as sagging of the rod, deflection of the tubing, vibration and external load.

Warning Warning Caution1. Be certain to match the rod

shaft center with the load and direction of movement when connecting.When not properly matched, problems may arise with the rod and tubing, and damage may be caused due to friction on areas such as the inner tube surface, bushings, rod surface and seals.

2. When an external guide is used, connect the rod end and the load in such a way that there is no interference at any point within the stroke.

3. Do not scratch or dent the sliding parts of the cylinder tube or piston rod, etc., by striking or grasping them with other objects.Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause faulty operation. Moreover, scratches or dents, etc. in the piston rod may lead to damaged seals and cause air leakage.

4. Prevent the seizure of rotating parts.Prevent the seizure of rotating parts (pins, etc.) by applying grease.

5. Do not use until you verify that the equipment can operate properly.After mounting, repair or modification, etc., connect the air supply and electric power, and then confirm proper mounting by means of appropriate function and leak inspections.

6. Instruction manual.The product should be mounted and operated after thoroughly reading the manual and understanding its contents.

Keep the instruction manual where it can be referred to as needed.

Caution

Mounting

Series CNSActuator Precautions 1Be sure to read before handling.

22

23

1. Readjust using the cushion needle.Cushions are adjusted at the time of shipment, however, the cushion needle on the cover should be readjusted when the product is put into service, based upon factors such as the size of the load and the operating speed. When the cushion needle is turned clockwise, the restriction becomes smaller and the cushion's effectiveness is increased.

2. Do not operate with the cushion needle in a fully closed condition.This will cause damage to the seals.

Cushions

1. Use clean air.If compressed air includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., it can cause damage or malfunction.

Air Supply

1. Install air filters.Install air filters at the upstream side of valves. The filtration degree should be 5µm or less.

2. Install an air dryer, after cooler or drain catch , etc.Air that includes much condensate causes malfunction of valves and other pneumatic equipment. To prevent this, install an air dryer, after cooler or drain catch, etc.

3. Use the product within the range of specifications for fluid temperature and ambient temperature.Take measures to prevent freezing, since moisture in circuits will be frozen under 5°C, and this may cause damage to seals and lead to malfunction.

Refer to the "Air Cleaning Equipment" catalog for details on compressed air quality.

1. Lubrication of non-lube type cylinder.The cylinder is lubricated at the factory and can be used without any further lubrication.

However, in the event that it will be lubricated, use turbine oil class 1 (with no additives) ISO VG32.

Stopping lubrication later may lead to malfunction due to the loss of the original lubricant. Therefore, lubrication must be continued once it has been started.

Caution

1. Do not use in environments where there is a danger of corrosion.Refer to the construction drawings regarding cylinder materials.

2. In dirty areas, such as dusty locations or where water, oil, etc. splash on the equipment, take suitable measures to protect the rod.

Operating Environment

Warning

1. Maintenance should be done according to the procedure indicated in the instruction manual.If handled improperly, malfunction and damage of machinery or equipment may occur.

2. Removal of machinery and supply and exhaust of compressed air.When machinery is removed, first check measures to prevent dropping of driven objects and run-away of equipment, etc. Then cut off the supply pressure and electric power, and exhaust all compressed air from the system.

When machinery is restarted, proceed carefully after confirming measures to prevent lurching of actuators.

Maintenance

1. Drain flushing.Remove condensate from air filters regularly. (Refer to specifications.)

Caution

Warning

1. Preparation before piping.Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove cutting chips, cutting oil and other debris from inside the pipe.

2. Wrapping of pipe tape.When screwing together pipes and fittings, etc., be certain that cutting chips from the pipe threads and sealing material do not get inside the piping.

Also, when pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the pipe.

Design & Selection

1. Confirm the specifications.Read the specifications carefully and use this product appropriately. The product may be damaged or malfunction if it is used outside the range of specifications of load current, voltage, temperature or impact.

2. Take precautions when multiple cylinders are used close together.When multiple auto switch cylinders are used in close proximity, magnetic field interference may cause the switches to malfunction. Maintain a minimum cylinder separation of 40mm. (When the allowable separation is indicated for each cylinder series, use the specified value.)

3. Pay attention to the length of time that a switch is ON at an intermediate stroke position.When an auto switch is placed at an intermediate position of the stroke and a load is driven at the time the piston passes, the auto switch will operate, but if the speed is too great the operating time will be shortened and the load may not operate properly. The maximum detectable piston speed is:

In cases of high piston speed, the use of an auto switch (D-F5NT) with a built-in OFF delay timer (approx. 200ms) makes it possible to extend the load operating time.

4. Wiring should be kept as short as possible.<Reed switch>

As the length of the wiring to a load gets longer, the rush current at switching ON becomes greater, and this may shorten the product's life. (The switch will stay ON all the time.)

1) For an auto switch without a contact protection circuit, use a contact protection box when the wire length is 5m or longer.

2) Even if an auto switch has a built-in contact protection circuit, when the wiring is more than 30m long, it is not able to adequately absorb the rush current and its life may be reduced. It is again necessary to connect a contact protection box in order to extend its life. Please contact SMC in this case.

<Solid state switch>

3) Although wire length should not affect switch function, use a wire 100m or shorter.

5. Take precautions for the internal voltage drop of the switch.<Reed switch>

1) Switches with an indicator light (Except D-A56)

• If auto switches are connected in series as shown below, take note that there will be a large voltage drop because of internal resistance in the light emitting diodes. (Refer to internal voltage drop in the auto switch specifications.)

[The voltage drop will be "n" times larger when "n" auto switches are connected.]

Even though an auto switch operates normally, the load may not operate.

• In the same way, when operating under a specified voltage, although an auto switch may operate normally, the load may not operate. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load.

2) If the internal resistance of a light emitting diode causes a problem, select a switch without an indicator light (Model D-A6).


3) Generally, the internal voltage drop will be greater with a 2 wire solid state auto switch than with a reed switch. Take the same precautions as in 1).

Also, note that a 12VDC relay is not applicable.

6. Pay attention to leakage current.<Solid state switch>

With a 2 wire solid state auto switch, current (leakage current) flows to the load to operate the internal circuit even when in the OFF state.

If the criteria given in the above formula are not met, it will not reset correctly (stays ON). Use a 3 wire switch if this specification will not be satisfied.

Moreover, leakage current flow to the load will be "n" times larger when "n" auto switches are connected in parallel.

7. Do not use a load that generates surge voltage.<Reed switch>

If driving a load such as a relay that generates a surge voltage, use a switch with a built-in contact protection circuit or use a contact protection box.


Although a zener diode for surge protection is connected at the output side of a solid state auto switch, damage may still occur if the surge is applied repeatedly. When a load, such as a relay or solenoid, which generates surge is directly driven, use a type of switch with a built-in surge absorbing element.

8. Cautions for use in an interlock circuit.When an auto switch is used for an interlock signal requiring high reliability, devise a double interlock system to avoid trouble by providing a mechanical protection function, or by also using another switch (sensor) together with the auto switch. Also perform periodic maintenance and confirm proper operation.

9. Ensure sufficient clearance for maintenance activities.When designing an application, be sure to allow sufficient clearance for maintenance and inspections.

1. Do not drop or bump.Do not drop, bump or apply excessive impacts (300m⁄s² or more for reed switches and 1000m⁄s² or more for solid state switches) while handling.

Although the body of the switch may not be damaged, the inside of the switch could be damaged and cause a malfunction.

2. Do not carry a cylinder by the auto switch lead wires.Never carry a cylinder by its lead wires. This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress.

3. Mount switches using the proper fastening torque.When a switch is tightened beyond the range of fastening torque, the mounting screws, mounting bracket or switch may be damaged. On the other hand, tightening below the range of fastening torque may allow the switch to slip out of position.

4. Mount a switch at the center of the operating range.Adjust the mounting position of an auto switch so that the piston stops at the center of the operating range (the range in which a switch is ON).

(The mounting position shown in a catalog indicates the optimum position at stroke end.) If mounted at the end of the operating range (around the borderline of ON and OFF), operation will be unstable.

Warning1. Avoid repeatedly bending

or stretching lead wires.Broken lead wires will result from applying bending stress or stretching force to the lead wires.

2. Be sure to connect the load before power is applied.<2 wire type>

If the power is turned ON when an auto switch is not connected to a load, the switch will be instantly damaged because of excess current.

3. Confirm proper insulation of wiring.Be certain that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch.

4. Do not wire with power lines or high voltage lines.Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit with these lines. Control circuits, including auto switches, may malfunction due to noise from these other lines.

5. Do not allow short circuit of loads.<Reed switch>

If the power is turned ON with a load in a short circuited condition, the switch will be instantly damaged because of excess current flow into the switch.


Model D-J51 and all models of PNP output type switches do not have built-in short circuit prevention circuits. If loads are short circuited, the switches will be instantly damaged.

∗ Take special care to avoid reverse wiring with the power supply line (brown) and the output line (black) on 3 wire type switches.

6. Avoid incorrect wiring.<Reed switch>

∗ A 24VDC switch with indicator light has polarity. The brown lead wire is (+) and the blue lead wire is (–).

1) If connections are reversed, a switch will operate, however, the light emitting diode will not light up.

Also note that a current greater than that specified will damage a light emitting diode and it will no longer operate.Applicable models:D-A53, A54

2) Note however, that in the case of 2 color indicator type auto switches (D-A59W), if the wiring is reversed, the switch will be in a normally ON condition.


1) If connections are reversed on a 2 wire type switch, the switch will not be damaged if protected by a protection circuit, but the switch will always stay in an ON state. However, it is still necessary to avoid reversed connections, since the switch could be damaged by a load short circuit in this condition.

∗ 2) If connections are reversed (power supply line + and power supply line –) on a 3 wire type switch, the switch will be protected by a protection circuit. However, if the power supply line (+) is connected to the blue wire and the power supply line (–) is connected to the black wire, the switch will be damaged.

∗ Lead wire color changes Lead wire colors of SMC switches and related products have been changed in order to meet NECA (Nippon Electric Control Equipment Industries Association) Standard 0402 for production beginning September, 1996 and thereafter. Please refer to the tables provided.Special care should be taken regarding wire polarity during the time that the old colors still coexist with the new colors.

Mounting & Adjustment


1. Never use in an atmosphere of explosive gases. The structure of auto switches is not intended to prevent explosion. Never use in an atmosphere with an explosive gas since this may cause a serious explosion.

2. Do not use in an area where a magnetic field is generated.Auto switches will malfunction or magnets inside cylinders will become demagnetized. (Consult SMC regarding the availability of a magnetic field resistant auto switch.)

3. Do not use in an environ-ment where the auto switch will be continually exposed to water.Although switches, satisfy IEC standard IP67 construction (JIS C 0920: watertight construction), do not use switches in applications where continually exposed to water splash or spray. Poor insulation or swelling of the potting resin inside switches may cause malfunction.

4. Do not use in an environ-ment with oil or chemicals.Consult SMC if auto switches will be used in an environment with coolant, cleaning solvent, various oils or chemicals. If auto switches are used under these conditions for even a short time, they may be adversely affected by improper insulation, malfunction due to swelling of the potting resin, or hardening of the lead wires.

5. Do not use in an environ-ment with temperature cycles.Consult SMC if switches are used where there are temperature cycles other than normal temperature changes, as they may be adversely affected.

6. Do not use in an environ-ment where there is excessive impact shock.<Reed switch>

When excessive impact (300m/s² or more) is applied to a reed switch during operation, the contact point will malfunction and generate or cut off a signal momentarily (1ms or less). Consult SMC regarding the need to use a solid state switch depending upon the environment.

7. Do not use in an area where surges are generated.<Solid state switch>

When there are units (solenoid type lifter, high frequency induction furnace, motor, etc.) which generate a large amount of surge in the area around cylinders with solid state auto switches, this may cause deterioration or damage to the switches. Avoid sources of surge generation and disorganized lines.

8. Avoid accumulation of iron powder or close contact with magnetic substances.When a large amount of ferrous powder such as machining chips or spatter is accumulated, or a magnetic substance (something attracted by a magnet) is brought into close proximity with an auto switch cylinder, it may cause the auto switch to malfunction due to a loss of the magnetic force inside the cylinder.

Operating Environment

1. Perform the following maintenance periodically in order to prevent possible danger due to unexpected auto switch malfunction.1) Secure and tighten switch mounting

screws.

If screws become loose or the mounting position is dislocated, retighten them after readjusting the mounting position.

2) Confirm that there is no damage to lead wires.

To prevent faulty insulation, replace switches or repair lead wires, etc., if damage is discovered.

3) Confirm the lighting of the green light on the 2 color indicator type switch.

Confirm that the green LED is on when stopped at the established position. If the red LED is on, the mounting position is not appropriate. Readjust the mounting position until the green LED lights up.

Maintenance

1. Consult SMC concerning water resistance, elasticity of lead wires, and usage at welding sites, etc.

Warning Warning

1. Construct so that the human body will not come into direct contact with driven objects or the moving parts of locking cylinders.Devise a safe structure by attaching protective covers that prevent direct contact with the human body, or in cases where there is a danger of contact, provide sensors or other devices to perform an emergency stop, etc. before contact occurs.

2. Use a balance circuit, taking cylinder lurching into consideration.In cases such as an intermediate stop, where a lock is operated at a desired position within the stroke and air pressure is applied from only one side of the cylinder, the piston will lurch at high speed when the lock is released. In such situations, there is a danger of causing human injury by having hands or feet, etc. caught, and also a danger of causing damage to the equipment. In order to prevent this lurching, a balance circuit such as the recommended air pressure circuits (p. 26) should be used.

Warning

Amount ofoverrun

Stop signal

3. In order to further improve stopping accuracy, the time from the stop signal to the operation of the lock should be shortened as much as possible.To accomplish this, use a device such as a highly responsive electric control circuit or solenoid valve driven by direct current, and place the solenoid valve as close as possible to the cylinder.

4. Note that stopping accuracy will be influenced by changes in piston speed.When piston speed changes during the course of the cylinder stroke due to variations in the load or disturbances, etc., the dispersion of stopping positions will increase. Therefore, consideration should be given to establishing a standard speed for the piston just before it reaches the stopping position.

Moreover, the dispersion of stopping positions will increase during the cushioned portion of the stroke and during the accelerating portion of the stroke after the start of operation, due to the large changes in piston speed.

Mounting

Warning1. Be certain to connect the rod end to the load

with the lock released.• If connected when in the locked condition, a load greater than the

turning force or holding force may operate on the piston rod and cause damage to the lock mechanism. The CNS series is equipped with an emergency unlocking mechanism, however, when connecting the rod end to the load this should be done with the lock released by simply connecting an air line to the unlocking port and supplying air pressure of 0.25MPa 2.5kgf/cm2 or more.

2. Do not apply an offset load to the piston rod.Particular care should be taken to match the load's center of gravity with the center of the cylinder shaft. When there is a large discrepancy, the piston rod may be subjected to uneven wear or damage due to the inertial moment during locking stops.

Selection

Warning1. When in a locked condition, do not apply a

load accompanied by an impact shock, strong vibration or turning force, etc.Use caution, because an external action such as an impacting load, strong vibration or turning force, may damage the locking mechanism or reduce its life.

2. Consider stopping accuracy and the amount of overrun when an intermediate stop is performed.Due to the nature of a mechanical lock, there is a momentary lag with respect to the stop signal, and a time delay occurs before stopping. The cylinder stroke resulting from this delay is the overrun amount. The difference between the maximum and minimum overrun amounts is the stopping accuracy.

• Place a limit switch before the desired stopping position, at a distance equal to the overrun amount.

• The limit switch must have a detection length (dog length) of the overrun amount + α.

• SMC's auto switches have operating ranges from 8 to 14mm (depending on the switch model).

When the overrun amount exceeds this range, self-holding of the contact should be performed at the switch load side.

∗ Refer to page 2 regarding stopping accuracy.

Series CNSSpecific Product Precautions 1Be sure to read before handling.Refer to pages 21 through 26 for safety instructions, actuator precautions and auto switch precautions.

Warning

1. Adjust the cylinder's air balance.Balance the load by adjusting the air pressure in the front and rear sides of the cylinder with the load connected to the cylinder and the lock released. Lurching of the cylinder when unlocked can be prevented by carefully adjusting this air balance.

2. Adjust the mounting positions of the detectors on auto switches, etc.When intermediate stops are to be performed, adjust the mounting positions of detectors on auto switches, etc., taking into consideration the overrun amount with respect to the desired stopping positions.

Caution

Air Pressure Circuits

1. Precautions when using the base unit and when changing bracket positions, etc.The lock unit and cylinder rod cover are assembled as shown in the drawing below. For this reason, it cannot be installed as in the case of common air cylinders, by using the basic type and screwing the cylinder tie-rods directly into machinery.

Furthermore, when brackets are replaced, the unit holding tie-rods may become loose and they should be retightened.

1. Be certain to use an air pressure circuit which will apply balancing pressure to both sides of the piston when in a locked stop.In order to prevent cylinder lurching after a locked stop, when restarting or when manually unlocking, a circuit should be used which will apply balancing pressure to both sides of the piston, thereby canceling the force generated by the load in the direction of piston movement.

2. Use a solenoid valve for unlocking which has a large effective sectional area, as a rule 50% or more of the effective sectional area of the cylinder drive solenoid valve.The larger the effective sectional area is, the shorter the locking time will be (the overrun amount will be shorter), and stopping accuracy will be improved.

3. Place the solenoid valve for unlocking close to the cylinder, and no farther than the cylinder drive solenoid valve.The less distance there is from the cylinder (the shorter the piping), the shorter the overrun amount will be, and stopping accuracy will be improved.

4. Allow at least 0.5 seconds from a locked stop (intermediate stop of the cylinder) until release of the lock.When the locked stop time is too short, the piston rod (and load) may lurch at a speed greater than the control speed of the speed controller.

5. When restarting, control the switching signal for the unlocking solenoid valve so that it acts before or at the same time as the cylinder drive solenoid valve.If the signal is delayed, the piston rod (and load) may lurch at a speed greater than the control speed of the speed controller.

Manual Unlocking

Warning

1. The unlocking cam is an emergency unlocking mechanism only. During an emergency when the air supply is stopped or cut off, this is used to alleviate a problem by forcibly pushing back the release piston and brake spring to release the lock.

2. When installing the cylinder into equipment or performing adjustments, etc., be sure to apply air pressure of 0.25MPa or more to the unlocking port, and do not perform work using the unlocking cam.

3. When releasing the lock with the unlocking cam, it must be noted that the sliding resistance of the cylinder will be high, unlike normal unlocking with air pressure.

4. Do not turn the unlocking cam (the arrow or mark on the unlocking cam head) past the position marked FREE. If it is turned too far, there is a danger of damaging the unlocking cam.

5. For safety reasons, the unlocking cam is constructed so that it cannot be fixed in the unlocked condition.

Caution

Locked condition

[Principle]If the unlocking cam is turned clockwise with an adjustable angle wrench or socket wrench, etc., the release piston is pushed back and the lock is released.Since the lever will return to its original position and become locked again when it is released, it should be held in this position for as long as unlocking is required.

Manually unlocked condition

1. A 3 position pressure center solenoid valve and regulator with check valve can be replaced with two 3 port normally open valves and a regulator with relief function.

1. Never operate the unlocking cam until safety has been confirmed. (Do not turn to the FREE side.)• When unlocking is performed with air pressure applied to

only one side of the cylinder, the moving parts of the cylinder will lurch at high speed causing a serious hazard.

• When unlocking is performed, be sure to confirm that personnel are not within the load movement range and that no other problems will occur if the load moves.

2. Before operating the unlocking cam, exhaust any residual pressure which is in the system.

3. Take measures to prevent the load from dropping when unlocking is performed. • Perform work with the load in its lowest position. • Use supports, etc. to prevent the load from dropping. • Confirm that balanced pressure is applied to both sides of the

piston.
