This example demonstrates a Pumping Program whose control depends on an external sensor. Assuming a
pressure sensor that is configured to detect a high pressure point and a low pressure point, the Pumping
Program individually selects whether it will react to the high or low pressure point.
The “Program Output” pin on the TTL I/O connector (pin 5) is used to select the high or low pressure point.
When low, the low pressure point is selected (PHASE 01), and when high, the high pressure point is selected
(PHASE 05). The Program begins by infusing continuously at 10.0 mL/hr (PHASE 02), while a background
trap is set for the low pressure point (PHASE 03). To create a delay when the pressure sensor is switched from
high pressure to low pressure when the “Program Output” pin is set, a small volume is pumped (PHASE 02,
06) before the background traps are set.
