76 Agilent 1200 Series Autosampler Reference Manual
3 Troubleshooting and Test Functions
Initialization Failed
The autosampler failed to complete initialization correctly.
The autosampler initialization procedure moves the needle arm and transport
assembly to their home positions in a predefined sequence. During
initialization, the processor monitors the position sensors and motor encoders
to check for correct movement. If one or more of the movements is not
successful, or is not detected, the error message is generated.
Probable Causes
• Mechanical obstruction.
• Defective sampling unit flex board.
• Defective transport assembly flex board.
• Defective sampling unit motor.
• Defective ASM board.
Suggested Actions
✔ Ensure unobstructed movement of the transport assembly.
✔ Exchange the defective sampling unit motor.
✔ Exchange the transport assembly.
✔ Exchange the ASM board.
