What do these products do in this instrument?
Bubble and pressure sensing: branch signals for workstation control
Provide bubble and pressure signals at defined locations. The workstation controller associates them with tasks, resources and confirmed delivery stages. Record communication success, completed motion and actual liquid results separately.
ABD provides bubble or liquid-state signals for defined tubing; PDM5 provides pressure information at a defined location. Configure module, position and action window separately; the controller associates affected samples or tasks.
Match sensing locations to specific fluidic problems
Bubble modules report bubble or liquid state in defined tube segments; pressure modules report pressure at defined positions. Before selecting mounting points, define the phase and abnormality to observe: aspiration, delivery, source depletion or branch-load changes. Associate sensor positions with affected samples, cuvettes or stations.
Connect signals, action windows and recovery conditions
The same signal may mean different things at different valve positions or operating phases. Record normal ranges and faults with actual liquids, tubing and sequences. The controller combines action timing, confirmed delivery status, volume records and sample identity to pause, review or recover; one pressure change cannot directly identify a blockage location or specific cause. Distinguish measured, estimated and unknown volumes; completion of a command does not prove actual liquid delivery.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Installation conditions | Specify tubing dimensions, liquid, sensing location and branch to observe. |
| Timing and baseline | Record valve positions, pump actions, normal changes and fault-detection windows. |
| Abnormality handling | Associate affected containers with confirmed delivery status and volume records; define conditions for review, continuation or re-execution. Distinguish measured, estimated and unknown volumes; completion of a command does not prove actual liquid delivery. |
| Operation | Specific operating conditions |
|---|---|
| Alarm recovery | Interruption stage, current vessel, delivered volume, resource status and retry conditions |
Alarm recovery
The controller should associate alarms with sample or well identity, operating stage and recorded delivered volume. Define stop, retry, discard or manual-recovery procedures for each fault, and preserve traceable records.
Resending the same command after partial delivery can duplicate an addition. Define stage-specific stop, resume or discard rules, and keep traceable records.
Test interruptions before delivery, during partial delivery and after completed delivery. Check whether retries cause misdelivery or duplicate dispensing.
Lost state records or unverified command repetition can cause duplicate actions. The controller determines task validity; sensors alone do not establish dose or method results.

| Alarm recovery | Test interruptions before delivery, during partial delivery and after completed delivery. Check whether retries cause misdelivery or duplicate dispensing. | Lost state records or unverified command repetition can cause duplicate operations |
Validate concurrency, restart after interruption and record traceability to prevent sample misassignment or duplicate dosing.
Can dispensing be repeated immediately after bubbles or abnormal pressure are detected?
First establish whether partial delivery has occurred and which container is affected. Immediate repetition may double-dose it. Act on the actual state and recheck the first cycle after recovery.
Connectable modules are not automatically plug-and-play. Recovery actions must match the current liquid and sample state.
