  • Page 1 Digital Electro-pneumatic Regulator EVD-1000/3000 Series INSTRUCTION MANUAL SM-A40414-A • Read this Instruction Manual before using the product. • Read the safety notes carefully. • Keep this Instruction Manual in a safe and convenient place for future reference.

  • Page 2: Preface

    • Since there are a wide variety of customer applications, it is impossible for CKD to be aware of all of them. Depending on the application or usage, the product may not be able to exercise its full performance or an accident may occur due to fluid, piping, or other conditions.

  • Page 3: Safety Information

    SM-A40414-A SAFETY INFORMATION SAFETY INFORMATION When designing and manufacturing any device incorporating the product, the manufacturer has an obligation to ensure that the device is safe. To that end, make sure that the safety of the machine mechanism of the device, the pneumatic control circuit, and the electric system that controls such mechanism is ensured.

  • Page 4: Precautions On Product Use

    SM-A40414-A SAFETY INFORMATION Precautions on Product Use DANGER Use the product within the specified voltage range. Applying voltage beyond the specified range may cause a malfunction, damage to the sensor, electric shock, or fire. Do not connect a load exceeding the rated output. The output circuit may become damaged or a fire may occur.
  • Page 5 Before using the product as an air blow with the control pressure of the secondary side released to the atmosphere, test the usage under actual conditions of use or contact CKD. The pressure may fluctuate depending on the piping and blowing conditions.
  • Page 6 When using the product out of the specified conditions or for a special application, consult CKD about the specifications. Do not use the product where it is exposed to direct sunlight or where water, oil, and other liquids may directly splash onto the product.
