After selecting the function, change '00', if needed, to a unique Program Label, from 0 to 99. See sec:
11.3.6, 'Pr:In': Program Selection Input for a full description. Place a Sub-Program Start Label, with a
unique number for each Sub-Program, from 0 to 99, at the starting Phase of each sub-program section.
When the Pumping Program encounters a Sub-Program Start Label in normal execution, it will interpret
the label as a Stop function, stopping the pump and ending the Pumping Program.
11.3.8 ‘LP:ST’: Define Starting Phase of Loop
Defines the start of a Program loop. For a full description of Program looping, see sec.
11.3.10, ‘LP:nn’: .
11.3.9 ‘LP:EN’: Define Continuous Loop End
Loops to the most recently executed, unpaired, ‘loop start’ Phase, or Phase 1 if none. This
function allows a section of the Program to be repeated continuously. For a full description of Program
looping, see sec. 11.3.10, ‘LP:nn’: .
11.3.10 ‘LP:nn’: Define Loop End and Loop Repetitions
nn
Repeats execution of the defined loop ‘nn’ times.
Loop starts and loop ends are uniquely paired during looping. When an unpaired ‘loop end’ function is
executed, it is paired with the most recent unpaired ‘loop start’ function executed (‘LP:ST’). If no
unpaired ‘loop start’ function exists, Phase 1 is used as an implied unpaired ‘loop start’. This pairing
defines the loop and the range of Phase numbers between the paired loop functions defines the scope of
the loop.
When a ‘loop end’ function is executed, Program operation continues with the ‘loop start’ function paired
with the loop end function. There are 2 ‘loop end’ functions: Loop continuous (‘LP:EN’) and Loop for a
preset number of iterations (‘LP:nn’), indicated by ‘nn’. Each time a paired ‘loop end’ function is
executed, an iteration of the loop is complete. With the ‘LP:nn’ function, after ‘nn’ number of loop
iterations, the defined loop is complete and Program execution continues with the next Program Phase
after the ‘loop end’ function. The loop is then no longer defined or paired.
While executing Phases within the scope of a defined loop, another ‘loop start’ and ‘loop end’ can be
paired and become a defined loop within the scope of the first loop, which is referred to as the outer loop.
The new loop being referred to as the inner loop. The pairing of a loop within a paired loop is referred to
as nesting of loops, with each loop being one nested layer for the duration of the loops pairing. Loops can
be nested for a total of 3 layers deep. Loops can only be nested within the scope of an outer loop.
11.3.11 'PS:nn': Pause Pumping
If ‘nn’ is non-zero, the Pumping Program will pause pumping (stops pumping) for ‘nn’ seconds. When
executed, the display will show
nn
, with ‘nn’ decrementing to indicate the number of seconds
until the next Program Phase is executed. After the pause interval, the next Program Phase will be
executed.
To set a pause time in tenths of seconds, select the decimal point between the digits. Simultaneously press
the 2 up arrow keys below the digits to set or clear the decimal point. Alternatively, press and hold the
right-most up arrow key until the right-most digit scrolls to 9. After 9, the decimal point between the 2
digits will toggle on and off . Release the key when the decimal point is displayed, or cleared,
as required. Now enter the required pause time from 0.1 to 9.9 seconds.
For pauses longer than the ‘99’ second maximum pause for this function, put the pause function within a
Program loop. A Program section with the following functions in consecutive Phases:
[LP:ST] [LP:ST] [PS:60] [LP:60] [LP:24],
will pause the Pumping Program for 24 hours.
