Tray Alignment
Tray Alignment
Tray alignment is required to compensate for small deviations in positioning
of the gripper which may occur after disassembling the module for repair.
The tray alignment procedure uses several tray positions as reference points.
Because the tray is a rectangle, a two-point alignment is sufficient to corrects
all other vial positions within the tray. On completion of the procedure, the
corrected gripper positions are stored in the instrument firmware.
NOTE The alignment procedure requires an 1100 Control Module G1323B with
firmware revision B.02.02 or higher. The screen with the alignment dialog box
can be found under the menus Views/System/Tests/Autosampler. The
alignment procedure must be done with the standard 100-position vial tray
installed.
WARNING The alignment procedure has to be performed in the correct order and
without skipping parts, to ensure a proper working Autosampler.
User Interface
In the Control Module the “Align Tray” function is located in the Control
display of the autosampler.
Additional information can be found in the on-line information systems.
The correct procedure for the Control Module are:
1 Set alignment to factory default:
• Go to Align/Tray and press button Default.
• Go to Align/Transport and press button Default.
• Wait while the Autosampler performs a reset and go back to
