Power Valve Precision Regulator If the reduced pressure supply and relief exhaust that may cause extreme changes in flow rate are repeated (main valve is fully opened and closed repeatedly), the nozzle flapper is deformed. This may cause the pressure set value to deviate or the diaphragm to break early. So, do not use under such conditions. Caution 1.
If there is any leakage, the cylinder, when the valve is deenergized, may move without stopping at mid-position. Therefore leakage from piping and fittings should be completely removed. When applying teflon sealing tape to the thread area, wind it round the thread area 1-2 times while ensuring the thread extends one or two screw pitches beyond the taped area.
(white) and COM (black) may not turn ON while pressure is increasing. Note 5) Maximum error value: Add the pressure gauge indicator error of 0.03 MPa to the setting needle error.

Solenoid valve Loosen set screw and take solenoid valve out vertically, otherwise it may cause damage to the solenoid valve. Never remove a valve at an angle. When mounting solenoid valve onto the base, plug pin assembly (base side) into receptacle assembly (body side) vertically.
Sometimes when the bowl is removed for a purpose other than replacing the element, the spacer may stick to the bowl and come off. In this case however, it may be returned to its installed position and used again. 2. Drainage should be discharged by the time it reaches the upper limit.
Surge voltage countermeasures When shutting off the DC power supply using an emergency circuit breaker, the valve may operate incorrectly due to surge voltage generated by other electric parts (e.g., the solenoid). To ensure that surge does not affect the valve, take anti-surge measures (diode for surge protection, etc.) or use a valve with diode to prevent reverse current.

Air-relieving port Tube attachment When this pressure switch is used in a place where water and dust splashes may occur, insert a tube in the air-relieving port, and bring piping of the opposite side up to the safe position to keep it from water and dust.
The output condition is also basically recovered to that before a power cut or deenergizing, but may change depending on the operating environment. Therefore, check the safety of the whole installation before operating the product.

Otherwise, malfunction may result due to noise. Ensure that the FG terminal is connected to ground when using a commercially available switch-mode power supply. When a switch-mode power supply is connected to the product, switching noise will be superimposed and the product specification can no longer be met.
If the SI unit is not assembled properly, inside PCBs may be damaged or liquid and/or dust may enter into the unit.

Note) It may be difficult to replace the cushion seal #6. Seal kit includes a grease pack (10 g). Order with the following part number when only the grease pack is needed.
If the element is used continuously without replacement, the element may be damaged. w Be sure to discharge the drain accumulated in the filter container. If the drain is not discharged, the accumulated drain flows to the outlet.
