The first 2 Phases set an event trap for a Syringe Filled Sensor and refills the syringe until the sensor is
triggered. When the sensor triggers the event, the pump’s pusher block will be synchronized with the Pumping
Program. It is assumed that the sensor is positioned to refill the syringe with 60 mL. A withdraw volume of 61
mL is set as a safety feature.
After the syringe is refilled, one 5 mL dispense is made every 5 hours. After 12 dispenses, the syringe is
refilled using the sensor again.

7.4.7 Example 7: Sub-Programs
This example shows some of the flexibilities provided by the Program Selection functions. The Pumping
Program starts by refilling the syringe with 50 mL at a fast pumping rate (Phase 1), then the Pumping Program
pauses for user sub-program selection (Phase 3). Then performs 5 dispenses of 10 mL at the selected rates,
then refills the syringe again and pauses for the next user sub-program selection.
The user selects the sub-program from a selector switch that is attached to the Expansion Connector (See sec.
9, Logic Interface: TTL Input and Output) . The pump is started from a start switch connected to the trigger
input (TTL I/O Pin 2). Up to 32 sub-programs can be addressed from the Expansion Connector.
The user is given the option of choosing one of three defined sub-programs.
1: Dispense 10 mL at 100 mL/hr (Phase 4)
2: Dispense 10 mL at 500 mL/hr (Phase 7)
3: Dispense 10 mL at 750 mL/hr (Phase 10)
After selecting the sub-program and pressing 'Start', the Pumping program continues execution at the selected
sub-program. After the 10 mL dispense, each sub-program jumps or continues with the loop counter function
(Phase 12). The first 4 loops continue Program Execution with the next user sub-program selection. After the
5th loop, the program continues with Phase 13, which jumps back to the syringe refill function and starts the
whole program over.
