Gripper Verification
ALS Gripper Verification Description
The verification procedure uses several vial positions as reference points to
verify the gripper alignment is correct. If verification indicates one or more
positions are out of alignment, the alignment procedure should be done.
Verifying the ALS Gripper Positions
Vial positions 1, 10, 55, 81, 91 (Lab Advisor B.02.07 and later) and 100 can be
used for position verification.
1 Insert empty capped vials into the vial tray at the positions to be verified.
2 Select the first vial position in the vial-position menu.
3 Select Go to selected position.
4 If the fingers of the gripper arm are aligned centrally above the vial, select
Pick vial to verify the gripper arm lifts the vial out of the tray correctly. If
there is a misalignment, the gripper must be realigned.
5 Select Put vial to verify that the gripper replaces the vial correctly. If there is
a misalignment, the gripper must be realigned.
6 Repeat the procedure for the next vial position.
