Specific Product Precautions
Selection
1.
Residual pressure disposal (outlet pressure removal) is not
possible for the AR20 to AR60 even though the inlet pressure
is exhausted. When the residual pressure disposal is per-
formed, use the regulator with a backflow function (AR20K to
AR60K).
Warning
Maintenance
1.
When using the regulator with backflow function between a
solenoid valve and an actuator, check the pressure gauge peri-
odically. Sudden pressure fluctuations may shorten the durabil-
ity of the pressure gauge. A digital pressure gauge is recom-
mended for such situation or as deemed necessary.
Warning
Mounting and Adjustment
1.
Set the regulator while verifying the displayed values of the in-
let and outlet pressure gauges. Turning the regulator knob ex-
cessively can cause damage to the internal parts.
2.
The pressure gauge included with regulators for 0.02 to 0.2
MPa setting is for up to 0.2 MPa use only (except the AR10).
Exceeding 0.2 MPa of pressure can damage the gauge.
3.
Do not use tools on the pressure regulator knob as this may
cause damage. It must be operated manually.
Warning
1.
Be sure to unlock the knob before adjusting the pressure and
lock it after setting the pressure. Failure to follow this proce-
dure 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.
A knob cover is available to prevent careless operation of the
knob. Refer to page 389 for details.
Caution
Orange mark
Be sure to read before handling. Refer to front matters 42 and 43 for Safety Instructions and pages 287 to 291 for F.R.L.
Precautions.
Note 1) Assembly of a bracket and set nuts
Note 2) Assembly of a bracket and 2 mounting screws
Note 3) Please consult with SMC regarding the set nuts for the AR50(K) and AR60(K).
Note 4)
in part numbers for a round pressure gauge indicates a type of connection thread. No indication is necessary for R; however, indicate N for NPT. Please contact SMC
regarding the connection thread NPT and pressure gauge supply for psi unit specifications.
Note 5) Pressure gauge for general purpose
