Where ports and interlocks fit in the instrument
Map port states and interlocks for sample, standard, reagent, wash and waste paths. Include shared sections, unintended connections and transport delay. Define whether detection stops during faults and how affected samples are flagged.
Include measurement, washing, bypass and fault states in the drawings. Shared volume and transport delay determine when a signal can be identified as a valid sample measurement.
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 analytical system integration task, confirm task state, sample/vessel identity, concurrent resources, interlocks and recovery.
Organize the sequence by actual architecture
- Create a port-state table for samples, standards, reagents, wash liquids and waste, covering measurement, displacement, washing, maintenance bypass and abnormal states.
- Match valve positions to permitted pump states in each branch. Verify the current source, receiver, shared segments and paths requiring isolation.
- After switching, renew the path according to actual volume and flow conditions. Confirm target composition and signal recovery at the receiver before allowing that measurement window to produce valid results.
- Check unintended connections, leakage when closed and liquid destinations after interruptions. Preserve sample identity and completed-stage records. Before rejoining the analytical program, confirm the actual path and blanks.
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. |
Compare product configurations by the roles on this page
| 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 |
| SV10 solenoid valve | On/off control or branch selection | Check normal state, differential pressure, flow direction and duty cycle; high-pressure tasks require a separately suitable configuration |
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.
Check delivery, response, blanks and fault recovery through the complete method cycle.
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.
Configure metering, continuous supply, liquid washing and air-containing waste removal separately. See Laboratory Automation for platform scheduling.
