When the Configuration tab is clicked and the Purge Setup button is clicked, the panel pictured below is displayed in the bottom right of the Configuration page. This panel defines where the robot is moved to purge the two dispense heads and the duration of the purge operation.

Figure 43-22: Purge Setup Sub-Panel

The purge operation is a pre-defined process that safely moves the robot to a designated position and dispenses fluids for a specified period of time. This function can be manually invoked from a number of pages and is used to test if a syringe is operating properly and to clear the needle. The purge operation performs the following steps:

Retracts the robot to the Z height specified by the Safe Location.
Moves to the "Approach" position that is the specified number of mm above the purge position.
Moves to the purge position with the syringe slide in the retracted position.
Turns on the syringe air supply for the specified number of seconds.
Retracts the robot to the Z height specified by the Safe Location.
Moves horizontally to the Safe Location.

For this function, the speed and acceleration of the robot is defined by the Robot Motion parameters. For each syringe head, the following fields and buttons are defined.
