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.
8.3.13 '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.
8.3.14 '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 when either:
1) A falling edge (high to low TTL transition) occurs on the TTL ‘Event Trigger’ input (pin 4).
2) A low level on the 'Event Trigger' input pin 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’.
After being triggered, the event trigger is reset. If an event trigger function is executed (either 'Et' or ES'
function) while another event trap is still set, the new event trigger will replace the previous event trap. Only
one event can be defined at any time.
8.3.15 'ES:nn': Setup Event Square Wave Trigger Jump Phase
nn
The 'Event Square Wave' function operates the same as the 'ET' 'Event' function, with the
exception of the triggering conditions.
The event is triggered with either:
1) The rising or falling edge of the TTL ‘Event Trigger’ input (pin 4).
2) The RS-232 ‘RUN E’ command.
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.
8.3.16 ‘Et:rS’: Event Reset
’Event Reset’ cancels a previously set event trap.
8.3.17 ‘CLr.d’: Clear Total Volume Dispensed
Sets the total volume dispensed to 0. Both infusion and withdraw volumes are reset.
