Issue

When samples are analyzed in the first row of any of the sample racks, the Qtegra software will lock up and the run will halt.

Environment

• ASX-1400
• ASX-1600

Resolution

1) Check to see if SmartStir is enabled by looking at the DIP switches on the back of the autosampler (plate will need to be unscrewed to access them) and see if DIP switch #10 is set to On (switch in up position). If it is, continue to next step.

2) Open ASX-1x00 Configuration program. If this program is not installed on the PC, it will need to installed. The software disc that came with the autosampler will have this program on it.

Note: Before connecting in the ASX-1x00 Configuration program, ensure that you are connected to the autosampler in Qtegra by selecting a configuration in Qtegra that does not have an autosampler present in it. This type of configuration may be called "Reset" or "Empty".

3) Connect to the autosapler by selecting the appropriate Comm Port to do so from the dropdown menu

Note: if the autosampler is connected using the tan colored RS232 cable, the Comm Port will most likely be COM1. This article can be used to determine the Comm Port if it is connected via USB: Determining the Autosampler COM Port

4) The Stir and Rinse Duration (see red box in picture below) should be set to a time that is no greater than 3s. If it is higher, change to 2-3s and click Upload Settings

Cause

The issue with SmartStir is if the stirring and rinse time is set too long, the Qtegra may ‘timeout’ waiting for a response from the ASX-1600 to complete the function. Usually, a setting of 2-3 seconds for stir and rinse duration is about the most you can have.
