Timer Operation LXT

A. Meter Delayed Control

A Meter Delayed Control measures water usage . The system 

regenerates at the programmed regeneration time after the 

calculated system capacity is depleted . The control calculates the 

system capacity by dividing the unit capacity by the feedwater 

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 .

B. 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 .
The meter and time clock controls will use and display cycles:
1 .  Backwash
2 .  Brine/Slow Rinse
3 .  Rapid Rinse
4 .  Brine Tank Refill
The filter controls will use and display cycles:
1 .  Backwash
2 .  Rapid Rinse
Pressing the Extra Cycle button during a regeneration cycle 

immediately advances the valve to the next cycle step position and 

resumes normal step timing .

C. 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, and does not 

rely on battery backup power .

D. 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 (backwash), 

and begins programmed time count down .

3 .  Press the Extra Cycle button once to advance valve to 

Regeneration Cycle Step #2 (brine draw & slow rinse) .

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 or upflow, the cycle step order 

may change.

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 will be 

cleared .

E. 

 

Control Operation During A Power Failure 

The LXT includes integral power backup . In the event of power 

failure, the control shifts into a power-saving mode . The control stops 

monitoring water usage . The display and motor shut down, but it 

continues to keep track of the time and day for a minimum of 12 

hours .
The system configuration settings are stored in a non-volatile 

memory and are stored indefinitely with or without line power .
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 . 

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 .
