・Electric conductivity and alarm setting (AL27)
6. Entering value settings for electrical conductivity of circulating fluid and hysteresis causes
circulating fluid to flow from the solenoid valve through to the DI filter to control the electrical
conductivity.
The following items can be set on “Electrical conductivity and alarm (AL27) setting” screen:
• Target electric conductivity value
• Electric conductivity hysteresis
• Setting of solenoid valve operation during the operation of the product:
“Control”/“Normally open”/“Normally closed”.
• “Enabling”/“Disabling” of “AL27: CH2 electric conductivity increase” alarm function
