7.3.9 Pause Pumping Function
Command: "FUN PAS <nn | n.n>"
If ‘nn’ is non-zero, the Pumping Program will pause pumping (stops pumping) for ‘nn’ seconds After the
pause interval, the next Program Phase will be executed. 'nn' can range from 00 to 99 or 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:
[FUN LPS] [FUN LPS] [FUN PAS 60] [FUN LOP 60] [FUN LOP 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
After the start trigger, the Program will resume with the next Phase. The start trigger can be from any
source, the TTL I/O Operational Trigger, or from RS-232.
If alarms are enabled, the buzzer will beep continuously while waiting for the start trigger.
7.3.10 Jump to Phase If External Trigger Function
Command: "FUN IF 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.
7.3.11 Setup Event Trigger Jump Phase Function
Command: "FUN EVN 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 or reset. This function has no other affect on the operation of the pump until it is triggered.
The event is triggered when either:
1) A falling edge (high to low TTL transition) occurs on the TTL ‘Event Trigger’ input (pin 4) or
2) A low level on the ‘Event Trigger’ input pin at the time when the function is executed.
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’.
After being triggered, the event trigger is reset. If an event trigger function is executed while another event
trap is still set, the new event trigger will replace the previous event trap.
7.3.12 'ES:nn': Setup Event Square Wave Trigger Jump Phase
Command: "FUN EVS nn"
The 'Event Square Wave' function operates the same as the 'EVN' 'Event' function, with the exception of
the triggering conditions.
This function will trigger on either the rising or the falling edge of the TTL 'Event Trigger' input (pin 4).
Therefore, a square wave function on the inupt pin can be used to toggle the pump between 2 sections of a
Pumping Program. An example of this would be a Pumping Program that switched between a slow and
fast pumping rate, controlled by a square wave input.
7.3.13 Event Reset Function
Command: "FUN EVR"
