Needle Up Failed
Error ID: 4017
The needle arm failed to move successfully from the seat or out of the vial to
the upper position.
The upper 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 upper 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.
