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.
The flow cell of the detector in the system is not supported by the
delay volume determination function.
See Vanquish Detector Flow Cells
detector flow cells. Check the detector flow cell and make sure it is in
the support list.
The fraction collection valve fails to return to home position due to a
temporary communication issue or the valve is worn seriously after
running for a long time.
First, run Self Test to recover the issue and check the audit trail for
more information. If not resolved, power cycle the device. If the issue
persists, contact Technical Support.
Invalid tube position is provided when setting in ePanel FC tab:
Invalid tube position is provided when manually moving needle to one
specific position by selecting Move Needle Position button on ePanel
FC tab.
Check the racks and make sure the Tube Position and Move Needle
Position are in correct format and in range.
Power cycle the device. If the issue persists, contact Technical Support.
Flow rate of upstream Vanquish pump is 0.
This may occur when performing Internal Needle Rinse via ePanel FC
tab or the flush function during a sequence running.
Turn the Vanquish pump on and set proper flow rate, then redo the
manual internal needle rinse or injection.
Be aware that the flush pump internal volume is 1000uL and limited
flush times are allowed.
When installing needle capillary (P/N: 6706.1010, ID x L: 0.18 x 415
mm) with flush buffer loop (50 µL), the flush number is 20 times in one
injection.
When installing needle capillary (P/N: 6706.1020, ID x L: 0.25 x 415
mm) with flush buffer loop (100µL), the flush number is 10 times in one
injection.
Current physical pusher status does not align with the configured
Needle movement mode (InVial, AboveVial). Need to manually adjust
the pusher status to be align with the needle movement mode.
Otherwise the sequence cannot be started.
The opening of left door will stop BCR scanning. After the door is
closed, the scanning will restart automatically.
