Please contact SMC regarding the connection thread PT and pressure gauge supply for psi unit specifications. Warning Selection 1. Although exhaust of the residual pressure to the inlet side is possible when eliminating the inlet pressure, exhaust is not possible when the set pressure is 5 MPa or less. Use the regulator with backflow function. Warning Maintenance 1. When using the regulator between a solenoid valve and an actuator, check the pressure gauge periodically. Sudden pressure fluctuations may shorten the durability of the pressure gauge. A digital pressure gauge is recommended for such situation or as deemed necessary. Specific Product Precautions Be sure to read before handling. Refer to back cover for Safety Instructions, andling Precautions for SMC Products (M-E3-3) and the Operation Manual for F.R.L. Precautions. Please download it via our website, http://www.smcworld.com Mounting and Adjustment Warning 1. Set the regulator while verifying the displayed values of the inlet and outlet pressure gauges. Turning the regulator knob excessively can cause damage to the internal parts. 2. Do not use tools on the pressure regulator knob as this may cause damage. It must be operated manually. Caution 1. Be sure to unlock the knob before adjusting the pressure and lock it after setting the pressure. Failure to follow this procedure can cause damage to the knob and the outlet pressure may fluctuate. Pull the pressure regulator knob to unlock. (You can visually verify this with the orange mark that appears in the gap.) Push the pressure regulator knob to lock. When the knob is not easily locked, turn it left and right a little and then push it (when the knob is locked, the orange mark, i.e., the gap will disappear). 2. Pulsation will be generated when the difference between the inlet and the outlet pressure is large. In this case, reduce the pressure difference between the inlet and the outlet. Consult SMC if the pulsation problem is not resolved. 46 AWAFM AFAFMAR AFAR AWAL AFARAL AC AW AL AR AFM / AFD AF Attachment
