Operation during a power cut
• During a power cut, the current valve position, cycle step time elapsed, and
time of day is stored for 24 hours, and will be restored upon when the power
supply is restored.
• During regeneration, when power is shutting down, the controller saves the
current regeneration data. When power is restored, the controller resumes the
regeneration cycle at the point where the power failed.
Caution
When the power supply is cut, the valve stays in its current position. The system
should include all required safety components to prevent overflows.
• All the program settings are stored in a permanent memory.
• During a power cut, the time is kept and the time of day is adjusted when the
power supply is restored (as long as this happens within 24 hours).
• After a power cut, the time of day will flash on the main display screen.
• Press any button on the display to stop the time of day flashing.
