"Stop Flow input activated" error when starting flow on a BioAccord system - WKB116664
Article number: 116664
SYMPTOMS
- "Stop Flow input activated" error observed on binary solvent manager after attempting to start flow
- Resetting the BSM clears the error
- All modules show "idle" after clearing the error, but the error returns when flow is set again
- Priming the BSM does not cause the error
ENVIRONMENT
- BioAccord
- ACQUITY RDa Detector
- ACQUITY UPLC I-Class Plus
- UNIFI
- waters_connect
CAUSE
The ACQUITY RDa is in power save mode and the stop flow safety feature was activated.
FIX or WORKAROUND
- Open the instrument system status panel (green circle with white check mark at bottom-right of the instrument system console).
- Put the ACQUITY RDa Detector into Operate mode.
- Reset the binary solvent manager.
- Start flow on the binary solvent manager.
- In the top pane of the status panel, if "Startup" shows "Error", select "Startup to Ready" from the top pane drop-down menu.
ADDITIONAL INFORMATION
The only current workaround is to infuse a low flow into the RDa then at the first opportunity manually put into Standby with a low flow to waste.
