Page 3: Design And Selection
Discontinue DESIGN AND SELECTION １） Inferior quality air will deteriorate the product characteristics and affect its ！ durability badly. Use an air dryer, filter and sub micron filter t o eliminate solid CAUTION material, moisture and tar and thus provide clean air from the pressure source. Regulator Air filter ５ μm Pneumatic equipment Pressure switch Air dryer Oil mist filter Ｅ Ｒ ３ ０ ０ Fig１ Recommended air circuit In the case where the secondary side air pressure is reduced, the secondary side air flows through the model ER３ 00 and will be discharged from the exhaust port. The inside of the secondary piping and that of the load side should be kept clean. ... -
Page 4: Usage And Maintenance
１ ） Be sure to follow the instructions provided below. Failure to follow these ！ CAUTION instructions may hamper normal pressure control. * Never adjust the primary pressure to less than that of the secondary pressure +0.049MPa while the input signal is on. * Never send an input signal (this includes the power supply with the voltage input type) when the primary pressure is at atmospheric level. * Install a pressure switch capable of detecting the ER300 primary pressure and turning off input signals (this includes the power supply with the voltage input type) to the ER300 when pressure is reduced. Reference: The pressure switch setting must be the maximum set pressure +0.049MPa or more, at the ER300. * Never connect the power supply and input signal groundingline to the ER300 body. ２ ） The best measures against noise such as of solenoid valve etc. is through surge protection with CR, Diode (DC) etc. The following measures are also acceptable: * Separate the power line from the ER300 signal cable. * Connect the ER300 signal cable with the shield cable. *1 * Install a line filter in the ER300 source power supply (for example, when using the DC power supply pack, install in the DC power supply pack AC side). Warning: When the above precautions are not provided, normal pressure control cannot be guaranteed. Important: * Connect the shield to the GND. * For the connection between the V, S, and M terminals, divide the shield cable. ... - Page 5 Discontinue INDEX ＥＲ３００ Series PARECT Electronic Regulator INSTRUCTION MANUAL No.SM‑276677‑A １ ． PRODUCTS １ ． １ Specifications ･･････････････････････････････････････････ ５ １ ． ２ Dimensions ････････････････････････････････････････････ ６ ２ ． WIRING ２ ． １ Terminal Box･･･････････････････････････････････････････ ７ ２...
