8. Replacing needle(s)
When needles are broken, bent or blunt it is recommended to replace them.
To replace a needle, follow the steps described below. The following tools are required for replacing
the needles:
•
Allen key (size 2)
•
A small piece of sandpaper
Step 1: Make sure the Autosampler III is initialized and ready
Before replacing the needles, the Autosampler III should be initialized. This ensures the needles can move,
to a position where they can easily be replaced. The Autosampler III should also be in idle state, indicated by
the blue light.
Step 2: Start "11-ReplaceNeedles" routine
Start the "11-ReplaceNeedles" routine from the HMI. The needles will move to the replace position and the
downholders will move down. After finishing the movement, the doors will automatically unlock.
Step 3: Loosen adjustment screw
After the doors are opened, the needle(s) that need to be replaced can be removed by loosen their adjusting
screw(s) with the Allen key.
Caution: Carefully replace the needles,
due to the sharpness of the needle tip.
