22 Series Auto Switch Mounting on lnstalling in Close Proximity to Each Other. When cylinders are used in close proximity to one another as in mounting patterns () through (), the magnetic force of the auto switch magnets in cylinder B may have an effect on the operation of the auto switches on cylinder A.

Please contact SMC for further information. d L d L. Avoid wiring patterns in which bending stress and pulling force are repeatedly applied to the lead wires. When a bending stress is repeatedly applied to the lead wires, be sure to secure the lead wire close to the switch and to maintain a bending radius of R to R8 or more as a guideline. Applying a stress or pulling force to the connection part of a lead wire and an auto switch may cause broken wires, or a sheath to be dropped outs. Be sure that no force of any kind is applied to the connection part. 96

23 Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page for Safety Instructions and pages to for Actuator and Auto Switch Precautions. on Using End Lock Type Operating Precautions. Do not use position solenoid valves. Avoid use in combination with position solenoid valves (especially closed center metal seal types). If pressure is trapped in the port on the lock mechanism side, the cylinder cannot be locked. Furthermore, even after being locked, the lock may be released after some time, due to air leaking from the solenoid valve and entering the cylinder.. Back pressure is required when releasing the lock. Before starting operation, be sure to control the system so that air is supplied to the side without the lock mechanism. There is a possibility that the lock may not be released. (Refer to the section on releasing the lock.). Release the lock when mounting or adjusting the cylinder. If mounting or other work is performed when the cylinder is locked, the lock unit may be damaged.. Operate with a load ratio of % or less. If the load ratio exceeds %, this may cause problems such as failure of the lock to release, or damage to the lock unit.. Do not operate multiple cylinders in synchronization. Avoid applications in which two or more end lock cylinders are synchronized to move one workpiece, as one of the cylinder locks may not be able to release when required. 6. Use a speed controller with meter-out control. It may not be possible to release the lock with meter-in control. 7. Be sure to operate completely to the cylinder stroke end on the side with the lock. If the cylinder piston does not reach the end of the stroke, locking and unlocking may not be possible. Operating Pressure. Apply air pressure of at least that shown in the table below to the port on the lock mechanism side. This is necessary to release the lock. Relation to Cushion. When the cushion valve on the lock mechanism side is closed MXS or nearly closed, the spline rod may not reach the stroke end, and consequently the lock may not engage. Moreover, if the lock does engage when the cushion valve is nearly closed, it may not be possible for the lock to release. Therefore, the cushion valve should be adjusted properly. Releasing the Lock Warning. Before releasing the lock, be sure to supply air to the side without the lock mechanism, so that there is no load applied to the lock mechanism when it is released. If the lock is released when the port on the other side is in an exhaust state, and with a load applied to the lock unit, the lock unit may be subjected to an excessive force and may be damaged. Furthermore, sudden movement of the spline rod is very dangerous. Manual Release. Insert the bolt, screw it into the lock piston, and then pull it to release the lock. If you stop pulling the bolt, the lock will return to an operational state. Thread sizes, pulling forces and strokes are as shown below. Bore size (mm) Thread size Pulling force (N) Stroke (mm), 6,, M x. x L or more M x. x L or more M x. x L or more. Remove the bolt for normal operation. It can cause lock malfunction or faulty release. Bore size (mm), 6,,, Operating pressure (MPa).7. Exhaust Speed. Locking will occur automatically if the pressure applied to the port on the lock mechanism side falls to. MPa or less. In the cases where the piping on the lock mechanism side is long and thin, or the speed controller is separated at some distance from the cylinder port, the exhaust speed will be reduced. Take note that some time may be required for the lock to engage. In addition, clogging of a silencer mounted on the solenoid valve exhaust port can produce the same effect. 97
