Troubleshooting and Test Functions
Needle Down Failed
Needle Down Failed
The needle arm failed to move down into the needle seat.
The lower position of the needle arm is monitored by a position sensor on the
sampling unit flex board. The sensor detects the successful completion of the
needle movement to the needle seat position. If the needle fails to reach the
end point, or if the sensor fails to recognize the needle arm movement, the
error message is generated.
Probable Causes
•
Needle installed incorrectly, or wrong needle type (too long).
•
Defective or dirty position sensor.
•
Defective motor.
•
Sticking spindle assembly.
•
Defective ASM board.
Suggested Actions
❏
Ensure the correct needle type is used, and installed correctly.
❏
Exchange the sampling unit flex board.
❏
Exchange the needle drive motor.
❏
Exchange the spindle assembly or sampling unit assembly.
❏
Exchange the ASM board.
