Specifi c Product Precautions
1. Residual pressure disposal (outlet pressure removal) is not
possible for the AR20-B to AR60-B even though the inlet
pressure is exhausted. When the residual pressure disposal is
performed, use the regulator with a backflow function
(AR20K-B to AR60K-B).
Warning
1. When using the regulator with backflow function 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.
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.
Warning
Orange mark
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
fl uctuate.
• 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. A knob cover is available to prevent careless operation of the
knob. Refer to page 97 for details.
Caution
Note 1) Assembly of a bracket and set nuts. Including 2 mounting screws for the AR50(K)-B and AR60(K)-B
Note 2) Please consult with SMC regarding the set nuts for the AR50(K)-B and AR60(K)-B.
Note 3) 첸 in part numbers for a round pressure gauge indicates a pipe thread type. No indication is necessary for R; however, indicate N for NPT.
Please contact SMC regarding the pressure gauge supply for psi unit specifi cations.
Note 4) Including one O-ring and 2 mounting screws. [ ]: Pressure gauge cover only
Note 5) In addition to the pressure switch body, lead wire with connector (2 m), adapter, lock pin, O-ring (1 pc.), mounting screw (2 pcs.) are attached.
[ ]: Switch body only. (Regarding how to order the digital pressure switch, please consult with SMC.
