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.
9.3.12 '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. To select the decimal
point, press and hold the right-most 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. While executing a pause
time set in tenths of seconds, the display will only show '01' seconds during the pause.
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.
If ‘nn’ is ‘00’ then the Pumping Program pauses and waits for a start trigger to resume the Program. The
display will show when waiting for a start trigger.
After the start trigger, the Program will resume with the next Phase. The start trigger can be from any source,
the ‘Start’/’Stop’ key, the TTL I/O Operational Trigger, or from RS-232. Any other key input will stop and
reset the Pumping Program.
If alarms are enabled, the buzzer will beep continuously while waiting for the start trigger.
9.3.13 'IF:nn': Jump to Phase If External Trigger
nn
The ‘IF’ function conditionally alters the Pumping Program’s execution based on an external
signal.
When executed, if the TTL I/O Program Input pin (pin 6) is low level, then the Pumping Program continues
operation with Phase number ‘nn’. Otherwise, the Pumping Program continues operation with the next Phase.
9.3.14 'Et:nn': Setup Event Trigger Jump Phase
nn
The ‘Event’ function sets a background event trap that is triggered by an external signal.
This one time background trap, or interrupt, stays set during the Pumping Program’s entire execution until it is
triggered, redefined, or reset. This function has no other effect on the operation of the pump until it is
triggered.
The event is triggered with either:
1) A falling edge (high to low TTL transition) on the TTL ‘Event Trigger’ input (pin 4).
2) A low level on the 'Event Trigger' input pin of at least 200 ms at the time the function is executed.
3) The RS-232 ‘RUN E’ command.
When triggered, the current operation of the pump and the Pumping Program is interrupted, and the Pumping
Program immediately continues operation (jumps to) with Phase number ‘nn’.
