Where paths and interlocks fit in the instrument
Manage feeding, sampling, washing and waste removal through port states, interlocks and maintenance bypasses. Define concurrent tasks and isolation after closure, and record medium and vessel states during anomalies.
Concurrent tasks must prevent wash liquid, waste or other formulations entering culture paths. Include fault states and maintenance bypasses on the same drawings.
Product responsibilities in this operation
Valves control the current source or destination; the associated drive performs metering or transfer. Port connections, actual positioning and shared-segment renewal must match the operation.
For this bioprocess integration task, confirm task state, sample/vessel identity, concurrent resources, interlocks and recovery.
Organize the sequence by actual architecture
- Include feeding, sampling, cleaning, waste removal and maintenance bypasses in the state table. Identify culture vessels, permitted concurrency and required isolation locations.
- Check rotary-valve source selection separately from tubing-pinch on-off control, coordinating drive permissions, interface state and current process stage.
- Check unintended connections, leakage and backflow in operating and fault states. Record cumulative material, sampling identity and unfinished actions.
- Before restart, check actual vessel and liquid states, then decide whether to resume or stop, preventing cleaning-liquid misrouting and duplicate feeding.
Define operating conditions for this task
| To define | Details |
|---|---|
| Actual operating conditions | Task state, sample or vessel identity, concurrent resources, interlocks and restart |
| Acceptance target | Test concurrent operation, limiting states and complete fault recovery; verify that identities, cumulative quantities and records match actual actions |
| Fault localization | Resource conflicts, communication loss or mismatched identities can cause delivery to the wrong destination or repeated dosing. |

| Product | Configuration option | Conditions to verify |

| MRV3 multiport rotary valve | Multiple-source selection | Compare 10-, 16- and 24-port options and port diagrams; verify high-pressure suitability separately |
Validate operation results at the receiver
Cover concurrency, boundary states and complete recovery after faults. Check that identity, cumulative volume and records match actual operations.
Include extended operation, power loss, depleted feed, blockage and post-maintenance restart. Check cumulative delivery and contamination boundaries.
Locate abnormalities and restore the next operation
Resource conflicts, communication interruptions or identity mismatches can cause misdelivery or duplicate dispensing.
Stop the affected branches and recover using execution records.
Evaluate fluidic feedback and biological process results separately. A component combination alone does not establish sterility or continuous-culture capability.
