9-12 Troubleshooting
9.2.5 Needle Motor Errors
Sampling and Horizontal Needle Motor errors occur if the needle inside the analyzer’s side door cannot
move up and down or side to side, respectively.
9.2.5.1 Sampling Errors
Try the following in the order shown.
1. Open the side door, and locate the sampling needle (the thin tube which passes through the
Wash Head).
a. If the needle is bent or damaged, call Abaxis Technical Support.
b. Move the needle away from any part it may be touching. If you move the needle,
reboot the analyzer using the switch on the back of the analyzer.
c. Make sure the Wash Head thumbscrews are tight (see picture of screws on the next
page). Tighten them if they are loose and select Retry .
2. If the error repeats:
a. Turn the analyzer off.
b. Grasp the needle and move it up and down as far as
able 3-4 times to relubricate the guide bars.
c. Turn the analyzer back on and run a blank.
If the error continues, call Abaxis Technical Support.
9.2.5.2 Horizontal Needle Motor Errors
Try the following in the order shown.
1. Examine the area to the right and left of the needle and Wash Head assembly for any block-
age (including salt build-up) preventing left and right motions. If anything is found:
a. Remove the obstruction and/or clean the salt debris.
b. Select Retry , or turn the analyzer off and on again, then attempt to run a blank.
c. If the issue repeats, call Abaxis Technical Support.
2. If no obstruction is found:
a. Turn the analyzer off.
b. Move the needle out of the dilution chamber (if it is in the down position) then move
the whole assembly left and right 3-4 times to redistribute the lubricant on the hori-
zontal bars.
c. Turn the analyzer back on and run a blank.
d. If the issue repeats, call Abaxis Technical Support.
