Why is the displayed pressure abnormal on my CKD EVD-3000?
- F
  Frank KellyAug 17, 2025
  Abnormal pressure display on your CKD Controller can stem from several causes. First, the primary side pressure might be insufficient; ensure it's at least the minimum working pressure. Second, check for leaks in the secondary side piping. Finally, a faulty pressure sensor could be the culprit, requiring you to replace the product, ensuring no excessive pressure is applied from other pipes.

Why is my CKD EVD-3000 Controller making a loud noise?
- L
  lryanAug 20, 2025
  A loud noise from your CKD Controller can be due to several reasons. It could be caused by significant leakage exceeding the maximum flow rate, or air entering from the secondary side piping beyond relief performance. Using the product in either of these states will drastically shorten its lifespan, so reconsider its usage. Also, ensure the primary side pressure is supplied before turning on the power and setting the input signal and make sure that the set input signal is not greater than primary side pressure. The primary side pressure should also be at least the minimum working pressure.

  If the pressure isn't displaying on your CKD Controller, here are a few things to check: * First, press any operation key in case the automatic power off function is enabled. Note that if the display turns on and then off after one minute, this function is enabled. * Second, ensure the power supply is correctly connected. * Finally, if neither of these resolves the issue, there may be a disconnection inside the EVD, requiring a product replacement.

  If you're unable to change settings on your CKD Controller, it might be because the key is locked. Release the key lock according to "3.2.2 Key lock" and then try changing the settings. If the operation keys still don't work, you may need to replace the product.

What to do if my CKD Controller outputs pressure after it's turned off?
- A
  adodsonAug 28, 2025
  If your CKD Controller outputs 1%FS or more pressure even when turned off, several factors could be at play. The zero point may have been increased with zero/span adjustment; in this case, install a 3-way valve on the secondary side if atmospheric pressure is needed. Also, ensure the input signal is set to 0% when turning off the power. If the product has been left unused for a long period with power off and primary side pressure supplied, set the primary side pressure to zero. If the secondary side pressure rises, turn on the power and set the input signal to 0%. Make sure there is no abnormality in piping and wiring. If problems persist, the EVD may be faulty, necessitating a product replacement.

Why won't the switch output turn ON on my CKD Controller?
- D
  David AshleyAug 30, 2025
  The switch output on your CKD Controller might not be turning on because it is disabled. Refer to "3.2.5 Switch output". If the issue persists, there may be a failure in the EVD, requiring the product to be replaced.

Why does the pressure not display on my CKD EVD-3000 Controller?
- E
  Eric SimmonsSep 12, 2025
  If the pressure is not displaying on your CKD Controller, it could be due to the automatic power off function being enabled. Press any operation key to check. If the display turns on and then off after one minute, the automatic power off function is enabled. Refer to "3.2.5 Automatic power off" to disable the automatic power off. Another possibility is that the power supply is not connected correctly; ensure the rated power is connected correctly. Finally, there may be a disconnection inside the EVD, in which case you should replace the product.
