Figure 34. Stack reference position
For the object stack/tray cooler, you must properly position the x, y, z axes in the Open
Autosampler system.
After x-, y-, z-axis positioning of stack cooler model 6DW or 12MT, add the following steps
to verify the correct installation of the module.
 To verify the correct installation of the module
1. Close the drawer manually.
Choose Menu > Setup > Objects > TrayHolders > corresponding device.
Press function key F1, Check Pos. The injection unit moves to the predefined position.
2. Open the bottom drawer manually.
3. Remember the z value. Turn the z axis all the way down to check that the black needle
guide of the injection unit fits neatly into the position hole of the drawer.
4. If the position is proper, turn the injection unit slider back to the original z value. Then
close the drawer.
5. If the position is off by one or two millimeters, compensate for any discrepancy in the x, y
position seen between the upper and lower drawer.
6. If the position is off by more than one or two millimeters, check the bracket attachment
of the module to the x axis carefully. If in doubt, loosen the claws again and reposition the
unit on the x axis.
If this action is not successful, check the x- to y-axis angle and the y- to z-axis angle. If one
of these angles is not 90°, make corrections.
Ensure also that the y axis runs parallel to the open drawer. If this is not the case, the
bracket alignment is probably out of square.
Note The y axis tolerance for the teaching point is limited to 129.4 mm (5.09 in.).
When defining the position of the stack cooler, make sure you stay within this
tolerance with the reference point at the top drawer.
