Timer Operation
Meter Immediate Control
A meter immediate control measures water usage and
regenerates the system as soon as the calculated system
capacity is depleted. The control calculates the system
capacity by dividing the unit capacity (typically expressed
in grains/unit volume) by the feed water hardness and
subtracting the reserve. Meter Immediate systems
generally do not use a reserve volume. However, in twin
tank systems with soft-water regeneration, the reserve
capacity should be set to the volume of water used during
regeneration to prevent hard water break-through. A Meter
Immediate control will also start a regeneration cycle at the
programmed regeneration time if a number of days equal
to the regeneration day override pass before water usage
depletes the calculated system capacity.
Meter Delayed Control
A Meter Delayed Control measures water usage and
regenerates the system at the programmed regeneration
time after the calculated system capacity is depleted. As
with Meter Immediate systems, the control calculates the
system capacity by dividing the unit capacity by the feed
water hardness and subtracting the reserve. The reserve
should be set to insure that the system delivers treated water
between the time the system capacity is depleted and the
actual regeneration time. A Meter Delayed control will also
start a regeneration cycle at the programmed regeneration
time if a number of days equal to the regeneration day
override pass before water usage depletes the calculated
system capacity.
Time Clock Delayed Control
A Time Clock Delayed Control regenerates the system on a
timed interval. The control will initiate a regeneration cycle
at the programmed regeneration time when the number
of days since the last regeneration equals the regeneration
day override value.
Day of the Week Control
This control regenerates the system on a weekly schedule.
The schedule is defined in Master Programming by setting
each day to either “off” or “on.” The control will initiates a
regeneration cycle on days that have been set to “on” at
the specified regeneration time.
Control Operation During Regeneration
During regeneration, the control displays a special
regeneration display. In this display, the control shows the
current regeneration step number the valve is advancing
to, or has reached, and the time remaining in that step. The
step number that displays flashes until the valve completes
driving to this regeneration step position. Once all
regeneration steps are complete the valve returns to service
and resumes normal operation.
Pressing the Extra Cycle button during a regeneration cycle
immediately advances the valve to the next cycle step
position and resumes normal step timing.
Control Operation During Programming
The control only enters the Program Mode with the valve in
service. While in the Program Mode, the control continues
to operate normally monitoring water usage and keeping
all displays up to date. Control programming is stored in
memory permanently, eliminating the need for battery
backup power.
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 (brine
draw & slow 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 (rapid 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, 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.
Valve Positions
The position label affixed to the brine cam indicates the
cycles and service positions of the control valve.
