6 Troubleshooting
Troubleshooting Guide
The Agilent SPS 4 is equipped with diagnostic tools such as power/error
indicator and initialization sequence on startup to assist in identifying the
problems.
Power/Error
Indicator: Provides useful information on the error state of the
autosampler.
Initialization
Sequence: Tests that the probe arm functions in all its movement
axes by moving through the standard and sample
positions for the currently loaded mat and rack settings.
To identify your problem:
• If the autosampler appears to have no power and the power/error
indicator is not illuminated, refer to “Power Supply Problems” on
Page 65.
• If the power/error indicator is not lit or the LEDs are lit RED, refer to
“Operating State Problems” on Page 65. For the error state indicated by
the power/error indicator, refer to “Error Indicator Codes” on Page 66.
• If the autosampler fails in the initialization sequence, refer to
“Initialization Problems” on Page 68.
• If the initialization sequence is successful but the autosampler has a
malfunction in the probing operation, refer to “Probing Problems” on
Page 69.
• If the initialization sequence is successful but you cannot control the
autosampler from the instrument control software, refer to
“Communication Problems” on Page 70.
If these diagnostic tools do not assist you in identifying your problem,
contact an authorized Agilent representative. Refer to the Agilent
Technologies website for your local representative’s contact details:
