Power Supply Problems
If the Agilent SPS 4 appears to have no power and the power/error
indicator is not illuminated:
1 Check that the power cable is connected to the power supply and that
it is turned on.
2 Visually check the Agilent SPS 4 and power lead for any electrical
damage.
3 If the Agilent SPS 4 still fails to initialize contact your Agilent customer
support representative.
Operating State Problems
The power/error indicator is used to identify the operating state of the
Agilent SPS 4:
• If it is lit GREEN then the Autosampler has power. It is reasonable to
assume that the autosampler is working correctly.
• If it is not lit, then turn off the power at the power switch on the rear
panel of the autosampler. Turn the power off at the power point. Check
that the power cable is correctly seated into the power supply. Check
the power plug from the power supply is inserted correctly into the
power supply inlet on the rear panel of the autosampler. Turn the
power on at the power point. Turn the power to the autosampler back
on at the power switch.
• If the autosampler initializes but the power/error indicator does not
illuminate then the indicator is potentially faulty. Contact your
authorized Agilent representative.
• If the autosampler does not initialize and the power/error indicator
does not illuminate then it is possible that either the power supply
or main board may be faulty. Contact your authorized Agilent
representative.
• If the autosampler does not complete initialization and the LEDs in
the power/error indicator are illuminated RED, the autosampler is in
an error state. Refer to the error codes in “Error Indicator Codes” on
Page 66 to identify the cause.
