Agilent Technologies G1314B - Wavelength Holmium Check Failed; Grating or Filter Motor Errors

98 Agilent 1260 Infinity VWD User Manual
7 Error Information
Detector Error Messages
Wavelength holmium check failed
Error ID: 7318
The holmium oxide test in the detector has failed. During the holmium
test, the detector moves the holmium filter into the light path, and
compares the measured absorbance maxima of the holmium oxide filter
with expected maxima. If the measured maxima are outside the limits, the
error message is generated.
Grating or Filter Motor Errors
Error ID: Grating: 7800, 7801, 7802, 7803, 7804, 7805, 7806, 7808, 7809;
Filter: 7810, 7811, 7812, 7813, 7814, 7815, 7816
The motor test has failed.
During the motor tests, the detector moves the motor to the end position
while monitoring the end- position sensor. If the end position is not found,
the error message is generated.
Probable cause Suggested actions
1 Misaligned/defective grating assembly.
• Ensure the flow cell is inserted correctly,
and is free from contamination (cell
windows, buffers, and so on).
• Run the filter-motor test to determine if the
filter motor assembly is defective. If
defective, please contact your Agilent
service representative.
• Run the grating-motor test to determine if
the grating assembly is defective. If
defective, please contact your Agilent
service representative.
Test 0 Failed: Filter motor.
Test 1 Failed: Grating motor.
