Integral Fraction Collector FT (VF-F20-A) Operating Manual
Description and Remedial Action
Power cycle the device. If the issue persists, contact Technical Support.
Power cycle the device. If the issue persists, contact Technical Support.
Air bubble is not detected by air bubble sensor embedded inside the
device 3 minutes after Autosampler injection.
First, re-perform the DVD function and observe if one air bubble (about
length of 2.5mm) can be seen to flow along the waste line (connecting
to fraction collection valve port 3 ) after the bubble retention time on
UV detector (around 0.2-0.3 minute ) for each time of injection.
If the air bubble can be observed, then re-do the DVD. If the issue
persists, contact Technical Support.
Air bubble is not detected by the UV detector.
Check if a correct DVD capillary (P/N: 6040.2330, IDxL. 0.13x850mm) is
installed between autosampler and detector inlet and if an empty vial
is installed at R:A1 position of autosampler.
Then purge the pump for a while and rinse the system with methanol
(not IPA) for 10 mins above with flow rate of 1.2mL/min, then with 10%
methanol/water at 1.2mL/min for another 10mins. Make sure both
collect position and waste position are involved. The purpose is to
eliminate air bubbles inside the flow.
Then re-do the DVD function and check if it can be implemented
successfully.
If the issue persists, contact Technical Support.
Air bubble sensor is not detected by system. Turn the device off, wait
for 5 seconds and turn it on again.
If the issue persists, contact Technical Support.
The fraction collection valve may be worn, as result it cannot be
switched to correct position.
Or it may be a temporary error, run self-test.
If the issue persists, contact Technical Support.
First, run self-test to recover the issue and check audit trail for more
information. If the issue cannot be resolved, power cycle the device.
If the issue still persists, contact Technical Support.
Power cycle the device. If the issue persists, contact Technical Support.
Make sure the left door is closed during sequence running. Close the
door and try again.
Flush pump cannot find home possibly due to pump plunger stall issue.
Run Self Test to recover the issue.
If the issue persists, contact Technical Support.
Internal CAN bus disconnect, or firmware failure.
Power cycle the device. If the issue persists, contact Technical Support.
