Teledyne Isco Foxy Jr and Foxy R1 Fraction Collectors - Example for Triggers
Perform fraction collection with the Foxy Jr or R1 Fraction Collector with the help of the Fraction Collection driver. For details, refer to Collecting Fractions: 
Setting Up Fraction Collection.
After running the Program Wizard, an empty trigger block is created in the program that must be filled with the commands required for the Foxy Jr/R1 Fraction Collector. The following is an example of how the trigger block could be filled in. Note that the Wizard automatically adds all the command lines to the program that are required to determine the start and end of fractionation, according to the settings made on the Fraction Collection pages.
Before starting the batch, make sure that the Foxy arm is in the position above the first collection tube.

Description: The FracStart trigger causes the valve to switch to the Collect position. The TubeChange trigger ensures that the valve is switched again (back to the Waste position) while the x/y-arm of the fraction collector is moved to the next position, and then back to the Collect position for the next tube. The FracEnd trigger causes the valve to switch back to the Waste position.
