intervals.
7.3.3 Decrement Rate Function
Command: "FUN DEC"
The decrement function subtracts the specified rate from the current pumping rate. For a full description,
see section 7.3.2, Increment Rate Function
7.3.4 Stop Pumping Operation and End The Program
Command: "FUN STP"
Stops the pumping operation and stops the Pumping Program. The Pumping Program will begin at Phase
1 when started again. An implicit ‘Stop’ function is executed when the Program exceeds the maximum
Phase number during operation.
If alarms are enabled, the buzzer will beep continuously when the Pumping Program stops.
7.3.5 Jump to Phase Function
Command: "FUN JMP nn"
The ‘Jump’ function alters the consecutive operation of Program Phases. When executed, the Pumping
Program will continue operation with Phase ‘nn’.
7.3.6 Define Starting Phase of Loop Function
Command: "FUN LPS"
Defines the start of a Program loop. For a full description of Program looping, see sec 7.3.8, Define
Loop End and Loop Repetitions Function
7.3.7 Define Continuous Loop End Function
Command: "FUN LPE"
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.7.3.8 Define Loop End and Loop Repetitions Function.
7.3.8 Define Loop End and Loop Repetitions Function
Command: "FUN LOP 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 (‘FUN LPS’). 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 (‘FUN LPE’) and Loop for
a preset number of iterations (‘FUN LOP nn’), indicated by ‘nn’. Each time a paired ‘loop end’ function is
executed, an iteration of the loop is complete. With the ‘FUN LOP 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.
