717 Autosampler error "Seal width too narrow" when running the adjust seals calibration - WKB6918
Article number: 6918
SYMPTOMS
- 717 Adjust Seals fails. CAL error: "Seal width Too narrow"
- Flow is at 1.1 mL/min in degassed methanol through a column; pressure stable at 500 psi
- Test cycles through the sequence as expected, moving the needle through the seals, monitoring changes in pressure
- Error triggered several minutes into the calibration sequence
- Compression test fails due to lack of seal calibration
Other observations:
- Auto zero transducer, pressure stable
- New seal pack, new injector assembly, new sample loop
- Injector top/bottom sensor adjusted to 5/16-inch spacing
- Autosampler purged thoroughly; no air bubbles observed
ENVIRONMENT
- 717+ Autosampler
CAUSE
High-pressure motor valve 1 is leaking. A leak within the fluidics pack prevents the adjust seals calibration from completing.
FIX or WORKAROUND
- Rebuild the high-pressure motor valve 1.
- Part number WAT045424 for the "VLV REBUILD KIT"
