TIMER OPERATION continued
Manually Initiating a Regeneration
1. When timer is in service, press the Extra Cycle button for 5
seconds on the main screen.
2. The timer advances to Regeneration Cycle Step #1 (rapid
rinse), and begins programmed time count down.
3. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #2 (backwash).
4. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #3 (brine draw & slow rinse).
5. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #4 (brine refill).
6. Press the Extra Cycle button once more to advance the valve
back to in service.
NOTE: If the unit is a filter or upflow, the cycle step order
may change.
NOTE: A queued regeneration can be initiated by
pressing the Extra Cycle button. To clear a queued
regeneration, press the Extra Cycle button again
to cancel. If regeneration occurs for any reason
prior to the delayed regeneration time, the manual
regeneration request shall be cleared.
Control Operation During A Power Failure
The SXT includes integral power backup. In the event of power
failure, the control shifts into a power-saving mode. The control
stops monitoring water usage, and the display 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. The valve system 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. If the treated water
output is important and power interruptions are expected, the
system should be setup with a sufficient reserve capacity to
compensate for regeneration delays.
