Needle Lock Failed
The lock assembly on the sampling unit failed to move successfully.
The upper and lower positions of the needle lock are monitored by position
sensors on the sampling unit flex board. The sensors detect the successful
completion of the needle lock movement. If the needle lock fails to reach the
end point, or if the sensors fail to recognize the needle lock movement, the
error message is generated.
Probable Causes
•
Defective or dirty position sensors.
•
Sticking spindle assembly.
•
Defective needle drive motor
•
Defective MTP board.
Suggested Actions
✔
Clean the position sensor.
✔
Exchange the needle drive motor.
✔
Exchange the sampling unit assembly.
✔
Exchange MTP board.
