My best wishes to you on New Year.
Thanx a lot for this help.V r at stage where Carousel moves, identify and v somehow get succeeds to go into IDLE mode by intercepting Z Axis sensor during the critical movement of Carousel carrier. When we performs Carousel test by OTHER TEST it rotates and comes to Tray E 118 Vial which is recommended for default tests , it hampers the tray carrier and DogPin slight touches the tray sometimes appears with Z Axis 2 error or Carousel Carrier error.
We tried to set the .5 / 1 mm settings of Z Axis and vials too in Service Utilities page but it never sets and problem remains almost same. Again we do some interception in Z Axis Three screw plate photo sensor for error removal.
Can you see now and inform us the catchy settings in this stage.
Actually we hv 3 Alliance suffered with same obvious behavior. Whole assembly replacement is too costly bcoz Waters provide new assembly type with upgrade for 2695 kit too. Which is expensive a lot for our couple of 2690 Alliance units. Yes in 2695 Alliance i will apply your instruction today.
Thanks for the help
Merry Xmas

if you remove the middle part of front panel and the carousel carrier, you should be able to remove the stainless steel plate (on which the carousel trays sit).
then put something under this plate (like some stripes of tape or maybe some sheets of thin carton; maybe about 0.5-1 mm?) put the steel plate back and reassemble the carrier and front panel.
Goal is to lift the trays just a bit, so that the magnetic sensor can sense the magnets of the trays again.
Other hint's, just guesses:
As a first try to see if this is really the issue, maybe put some small piece of magnetic foil on top of the magent position of each tray (make sure it stays on the tray and is not too thick).
Or if you have newer trays with newer (stronger) magnets on them, try with them (thought: slight fading of the magentic field of the magnets during time, maybe if the trays were dropped several times or by temperature changes).
