Modular F.R.L. Unit (This is not applicable to VHS40 and VHS50) Body size Symbol 20 30 40 50 Applicable model AC20 AC25,30 AC40 AC50, AC60Note) Note) When the valve is mounted on AC60, the flow rate may decrease depending upon the mounting position.
If the operating pressure is too low, low speed operation may not be stable depending on the condition of the load. Furthermore, the maximum speed may be restricted depending on the pneumatic circuit or operating pressure. 2. Grease packs When maintenance requires only grease, use the following part numbers to order. Grease pack GR-L-005 (5g) GR-L-010 (10g) GR-L-150 (150g) 8
(Solid state) When two switches are connected in parallel, malfunction may occur because the load voltage will increase when in the OFF state.
However, depending on the number of switches in the ON state, the indicator lights may sometimes get dark or not light up, because of dispersion and reduction of the current flowing to the switches.
Applicable speed controller Note) Sometimes the work piece may not be gripped precisely because of excessive speed in finger opening and closing.
Faulty wiring or short circuit may result in breakage or burning-out of the switch. When stripping the cable clad, be careful about the orientation of the cable being stripped. The insulator may be accidentally torn or damaged depending on the orientation, as shown on the right.
If tightened insufficiently, nut may be loosened and it may cause the air leakage or tube coming off. When using soft copper tube, first tighten the nut by hand and then give it an additional one turn with wrench. Use JIS H3300, equivalent to seamless tube C1220T-0, as soft copper tube. If using any other type, it may cause the air leakage or tube coming off. 1 2 3 2 1 4 107

The displacement may increase after the action of an impact load.
OThe valve may be used in low tsmpsrature applications down to 26"F it the air is sutficiently tree of moisture. Please use an appropriate dryer to ensure dry air and prevent the valve lrom freezing. OThe double solenoid valve must be energized for at least 0.1 second o( more to enaurg proper operation.

Rotation Speed Range Model: 10, 15, 20O.O3 0.3 sec,/90' Model 300.04-0.3 sc,/90' lf a rotation soeed is used slower than 0.3sec/90", sticking may occur.
(Solid state) When two switches are connected in parallel, malfunction may occur because the load voltage will increase when in the OFF state.
A contact protection box should be used in any of the above situations, as the life of the contacts may be reduced. (They may stay on continuously.) Hysteresis is the distance from the position at which piston movement operates an auto switch, to the position at which reverse movement turns the switch OFF. This hysteresis is included in part of the operating range (on one side).
Brown [Red] When two switches are connected in parallel, malfunction may occur because the load voltage will increase when in the OFF state.

Take careful note of the tightening torque when replacement is performed because if the mounting screws are not tightened sufficiently, air leaks or other problems may occur. In addition, it is also possible to replace the fitting assembly only on Onetouch fitting type port block assemblies. Refer to the part numbers below.
Allow extra length when piping since the tubing may crush if bent more than the min. bending radius. Note 4) Consult P/A if using any other fluids. Max. Operating Pressure 3 TH0402 Max.
(Otherwise, delay in response or cylinder malfuction may result.) 1 Ensure that voltage leakage across the coil is as follows. DC coil: No more than 2% of the rated voltage.
