Compact Guide Cylinder If the space is not sufficient, the magnets in adjacent cylinders may cause the auto switches to malfunction.
Note 3) The number of stations that may be displayed is longer than the manifold number of stations.
When the handle is rotated with a tool, it may apply excessive torque to the handle or inside the valve body and it may cause damage. Rotate the handle by hand. 9. When locking the valve with LOTO feature in the closed position, use safety lockout hasp. (AP3657, AP4657, AP3157, AP3900) The valve with LOTO feature has a built in LOTO capability.
Note 3) The number of stations that may be displayed is longer than the manifold number of stations.
Furthermore, abnormal temperature rise caused by adiabatic compression may result in the tube bursting. Note 2) Do not use this product in a manner in which the tube is not fixed. Observe the lesser value of the maximum operating pressure between the tube and fitting. A material change over a long duration or due to high-temperature may cause leakage.
If the tightening torque is exceeded the mounting screws may be broken. IP67 protection cannot be guaranteed if the screws are not tightened to the specified torque. If a large manifold valve is mounted, lift the unit so that stress is not applied to the connecting part while transporting. The stress may cause breakage of the connecting part.
Note3) Due to the different materials used, changing only the seal may prove inadequate.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a short time, it may be adversely affected.
Note) If fittings are over-tightened, air leakage may result due to breaking of fitting threads or deformation of the gaskets. However, if fittings are not tightened sufficiently, loosening of the threads and air leakage and may occur. 2) Follow the indication when using fittings over than SMC.
The set pressure may vary depending on the elapsed time and change in ambient temperature after pressure setting. If the setting value varies, adjust with the handle. If the directional control valve (solenoid valve, mechanical valve etc.) is mounted and ON-OFF is repeated for a long time, the set pressure may vary. If the setting value varies, adjust with the handle.
Note 4: When short period power shortage (including instantly recovered shortage) is recovered, it may take a longer starting period than usual starting or may not start due to the protective devices.
The set pressure may vary depending on the elapsed time and change in ambient temperature after pressure setting. If the setting value varies, adjust with the handle. If the directional control valve (solenoid valve, mechanical valve etc.) is mounted and ON-OFF is repeated for a long time, the set pressure may vary. If the setting value varies, adjust with the handle.
If the tightening torque is exceeded the mounting screws may be broken. IP65 protection cannot be guaranteed if the screws are not tightened to the specified torque. If a large manifold valve is mounted, lift the unit so that stress is not applied to the connecting part while transporting. The stress may cause breakage of the connecting part.
The auto switch may be damaged if a screw other than the one supplied is used.
If mounting is done with lock engaged, lock mechanism may be damaged. * Remove bolt under normal operations. It may cause malfunction of locking and release. r Use with load 50% or less of rated capacity. Rubber cover If cylinder is used at 50% load capacity or more, lock may be damaged. t Do not use two cylinders in parallel at same time.
It may cause the fittings to fracture or the tubing to crush, explode or come loose. 7. Do not abrade, entangle or scratch the tubing. It may cause the tubing to crush, explode or come loose. Nozzle tightening torque range 12 to 14Nm Insufficient tightening may cause loosening of the nozzle. 15-7-11 12 Series VMG Specific Product Precautions 2 Be sure to read before handling.
When the diaphragm is made of PTFE Please note that when the product is shipped from the factory, gases such as N2 and air may leak from the valve at a rate of 1cm3/min (when pressurized). 2. When operated at a very low flow rate, the series LV with flow rate adjustment may vibrate, etc. depending on the operating conditions.
Furthermore, abnormal temperature rise caused by adiabatic compression may result in the tube bursting. Note 3) Do not use this product in a manner in which the tube is not fixed. Observe the lesser value of the maximum operating pressure between the tube and fitting. A material change over a long duration or due to high-temperature may cause leakage.
If heat cannot dissipate, the product may over heat and it may damage the product. Mounting screw specifications and tightening torques Use stainless steel screws with appropriate length. Tighten the screws to the recommended tightening torque. The internal components may get damaged if the maximum screw-in depth is exceeded.
One of the following may have occurred. (Fault) Valve coil has a short circuit. Pressure sensor has a short circuit. Pressure sensor has a failure or a disconnection. No connection between SI Unit and vacuum manifold. Disconnection between SI Unit and vacuum manifold. Red ON --One of the following may have occurred.
