V. Controller Operation (cont.)
C. Control Operation During A Power Failure
The controller includes integral power backup. In the event of a
power failure, the control shifts into a power-saving mode. The dis-
play and motor shut down, but it continues to keep track of the time
and day for a minimum of 48 hours.
The system configuration settings are stored in a non-volatile
memory and are stored indefinitely with or without line power. The
Time of Day flashes when there has been a power failure. Press any
button to stop the Time of Day from flashing.
If power fails while the unit is in regeneration, the control will save the
current valve position before it shuts down. When power is restored,
the control will resume the regeneration cycle from the point where
power failed. Note that if power fails during a regeneration cycle,
the valve will remain in it’s current position until power is restored.
System installation should include all required safety components to
prevent overflows resulting from a power failure during regeneration.
The control will not start a new regeneration cycle without line power.
If the valve misses a scheduled regeneration due to a power failure,
it will queue a regeneration. Once power is restored, the control will
initiate a regeneration cycle the next time that the Time of Day equals
the programmed regeneration time. Typically, this means that the
valve will regenerate one day after it was originally scheduled.
