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 affect 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’.
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.
9.3.15 '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.
9.3.16 'Et:rS': Event Reset
’Event Reset’ cancels a previously set event trap by either the 'ES' or 'ET' function.
9.3.17 ‘tr:aa’: Override Operational Trigger Configuration
aa
Sets the Operational Trigger (pin 2) to mode ‘aa’, overriding the default setup Operational
Trigger Configuration. See Sec. 8.4, ‘TTL I/O Operational Trigger Default Configuration’, for the settings
for parameter ‘aa’. The default setting for the Operational Trigger is always used to start the Pumping
Program.
9.3.17.1 Trigger Event Trap
‘Trigger Event Trap’ redirects a stop pump trigger to the background event trap. Instead of
stopping the pump, an event defined by the ‘Event’ or ‘Event Square Wave’ function will be triggered,
causing the Pumping Program to continue execution at the Phase number defined in the Event function.
If an Event Trap has not been defined, then the Pumping Program continues execution at the next program
phase. This is useful if the pump is executing a continuous infusion phase. The pump can can continue to
infuse until a foot swtich is pressed, The pumping proram can then jump to a different phase, such as a
withdraw phase, then stop the pump.
The Trigger Event Trap is a one-time function. After triggering an Event Trap, the Trigger Event Trap is
cleared. The Trigger Event function will not effect the current trigger configuration.
