01 Answer first
Which disturbances should a blower-filler FAT challenge?
Select safe, reproducible cases from the approved sequence and risk review: normal startup, planned slowdown, filler starvation, downstream blockage, machine fault, transfer interruption, permitted utility-loss simulations and controlled restart. For each case, define the initial state, trigger, expected signals, bottle disposition, recovery limit, quality checks, data source and factory-versus-site closure.
02 Where it fits
Position in the project journey
Integrated FAT preparation - after the wet-end design is approved and before the factory protocol is released.
03 Buyer inputs
What the buyer should prepare
- Approved bottle, reference output, transition priorities and acceptance definitions
- Required disturbances, witness points, data retention and deviation rules
- Product-quality checks and authority for bottle or filled-product disposition
- Known factory simulation limits and mandatory site-only follow-up cases
04 Allot Tech and manufacturing-resource inputs
What should be clarified or provided
- Approved wet-end sequence, signal list and prerequisites for each challenge
- Safe trigger or simulation method with expected machine and conveyor response
- Time-aligned event, speed, state, reject and quality-data capture method
- Executed result, deviation owner, retest status and site carryover register
Allot Tech coordinates requirement, quotation and project communication. Detailed engineering, manufacture, testing, documentation and confirmed service are performed by selected manufacturing resources according to the signed scope.
05 Technical scope
Questions and work to control
Translate the Released Sequence Into Challenge Rows
Do not redesign integration during FAT. Start from the approved operating philosophy and select the transitions that matter to safe control, bottle condition and accepted output. Each row should state the setup, trigger, expected states, observable result, acceptance rule and permitted simulation.
- Controlled initial operating state
- Reviewed trigger or simulation method
- Expected state and signal sequence
- Acceptance rule and responsible witness
Capture Controls and Package Evidence on One Timeline
Record machine states, speed references, fault and permissive changes, conveyor behavior, rejects and operator actions with a common time basis. Pair those records with bottle, fill and closure checks so a controls response is not accepted while the resulting package remains unverified.
- Common clock or reconciled event times
- State, speed, alarm and operator record
- Bottle and filled-package sample identity
- Reject, hold and affected-output disposition
Separate Factory Closure From Site Carryover
Factory utilities, production duration, downstream equipment or safety constraints may prevent a valid reproduction of some installed conditions. Mark those cases untested or partially tested, define their site prerequisites and carry them into commissioning or SAT instead of converting a demonstration into unsupported proof.
- Factory condition and simulation limit
- Evidence actually obtained
- Open site prerequisite and responsible party
- Commissioning or SAT test and closure date
Buyer questions answered
Practical answers before you request a quotation
Does this page replace the blower-filler integration design?
No. It assumes the rating, transfer, controls and safety basis is already approved and converts that basis into dynamic FAT evidence.
Must every possible fault be forced at FAT?
No. Select risk-based cases and use only reviewed, safe simulation methods. Record conditions that must be verified at site.
What makes a disturbance result reviewable?
Record the setup, trigger, time-aligned states, bottle or product checks, recovery result, witness decision and deviation status.
Can a steady production run pass the dynamic FAT?
Not by itself. It may support a separate capacity or quality test but does not demonstrate stop and recovery behavior.
06 Responsibility
Assign the owner before the work is due
Land, building and civil work, permits, import and customs, local taxes, site utilities, unloading, lifting, local labor, travel support and commissioning materials are not automatically included. Confirm every responsibility before order.
07 Common risks
What commonly creates avoidable uncertainty
- The FAT repeats steady running but never challenges a real transition
- A fault is improvised without a reviewed safe simulation method
- Machine logs, witness notes and bottle-quality checks use different time bases
- A site-dependent case is marked passed although the factory could not reproduce it
08 Acceptance or completion
How to know the stage is complete
The dynamic FAT closes when every approved challenge has a controlled initial condition and trigger, observed states match the released sequence, bottle and filled-product disposition is documented, recovery and accepted-output criteria are evaluated, deviations are closed or assigned and site-only tests remain visible.
09 Required documents
Records that support the decision
- Approved dynamic FAT challenge matrix
- Released sequence, signal and alarm references
- Time-aligned event, output and package-quality record
- Deviation, retest and site-carryover register
Evidence basis
Official references and project limits
These primary sources support the general planning principles used in this guide. The rules, evidence and responsible authority for the actual project country must still be confirmed locally.
