Autosampler Error Messages
The processor monitors the current drawn by each motor and the time the
motor is drawing current. The current drawn by the motors is dependent on
the load on each motor (friction, mass of components etc.). If the current
drawn is too high, or the time the motor draws current is too long, the error
message is generated.
Needle Down Failed
Error ID: 4018
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 cause Suggested actions
1 Mechanical obstruction.
Ensure unobstructed movement of the
transport assembly.
2 High friction in the transport assembly.
Please contact your Agilent service
