What to do if CYLINDER FAIL signal appears on YOKOGAWA Measuring Instruments?
- K
  Kevin KochAug 12, 2025
  If the 'CYLINDER FAIL' signal appears on your YOKOGAWA Measuring Instruments, first, ensure the PG2 pressure gauge in the control box displays the correct preset value while in cleaning mode. If the reading is low, check for loose connections and readjust accordingly. Also, remove any dirt from the cylinder barrel and apply a thin layer of grease. Degraded lubricating grease can also cause this issue, so cleaning and re-greasing are important. If the slide of the cylinder is in an upper position, refer to section 6.5.

What to do if a smaller quantity of chemical solution is fed to holder in YOKOGAWA PH450G?
- S
  Sheila MurphyAug 17, 2025
  If a smaller quantity of chemical solution is being fed to the holder in your YOKOGAWA Measuring Instruments, inspect the thin covering in the bottom of the metering tank and replace it if it's deteriorated or damaged. If the thin covering is fine, check for leaks around the SV1 solenoid valve (in the control box) that's used for forced feeding of the chemical solution. If air flows through the valve when closed, replace it. Also, check the chemical solution in the cleaning chamber for traces indicating backflow into the chemical tank. If the bleed valve is clogged due to reverse flow, clean it.
