A machine can be installed, connected and switched on without being ready for production. Moving equipment can disturb alignment, settings, electrical connections, foundations and utility interfaces. Problems may appear only when the machine runs at normal speed, handles a real product or operates for an extended period.

For plant heads, maintenance managers and project engineers, acceptance should depend on evidence, not a contractor’s statement that installation is complete. Machine performance testing after relocation provides a practical way to compare the machine’s condition before and after the move, verify functions that directly affect production, document defects and establish clear responsibilities for resolving issues before final handover.

Define What “Ready for Production” Means

Before dismantling starts, the plant owner and relocation contractor should agree on the conditions that must be satisfied before handover. Otherwise, one party may consider installation complete when the other expects calibrated output, a successful production run and all documentation.

Separate acceptance into clear stages:

• Installation completion: The machine is positioned, assembled, anchored and connected according to approved drawings and manufacturer instructions.

• Functional readiness: Controls, drives, sensors, utilities and safety functions work as intended.

• Performance acceptance: The equipment achieves agreed output, quality, accuracy and repeatability under defined test conditions.

• Handover: Records, training, open actions, spares and operating information have been transferred as required by the contract.

Not every project needs four separate sign-offs, but the responsibilities and evidence for each stage should be clear. Record acceptance criteria in the scope of work before the move, including which tests the contractor performs, which the OEM supervises and which the plant team witnesses.

Establish a Reliable Pre-Move Baseline

Post-relocation results are meaningful only when the team knows what the machine was doing before it was moved.

Collect available records such as:

• Typical output and cycle time for representative products.

• Product measurements, process capability results and rejection or rework rates.

• Alarm history, recurring faults and recent maintenance work.

• Vibration, temperature, pressure, motor current or other condition readings, where relevant.

• Calibration status, machine settings, recipes, PLC and drive backups.

• Tooling lists, machine configuration, photographs and connection drawings.

Choose a representative operating condition and document it. If the machine previously had a known defect, record it rather than treating the old condition as a perfect benchmark.

Inspect the Receiving Site Before Installation

A machine may be in good condition but perform poorly because the new location is not ready for it. Check the receiving site before transport wherever possible, when changes are still relatively easy to make.

Foundation, Access and Layout

Check floor or foundation capacity, anchor locations, levelling provisions, clearances and maintenance space against approved drawings.

Utilities and Interfaces

Verify that the new site can provide the required electrical supply, compressed air, cooling, hydraulic power, extraction, process connections and network access. Confirm capacity as well as connection size.

Upstream and Downstream Equipment

Identify interfaces with conveyors, feeders, packaging equipment, dust collection, central controls and material-handling systems. Identify who owns each connection and test. This prevents a machine from passing an isolated test but failing to run as part of the production line.

Check Mechanical Installation and Condition

After reassembly, inspect the parts most likely to be disturbed by lifting, transport or installation. Use the manufacturer’s instructions and machine-specific drawings rather than a generic list alone.

Verify, as applicable:

• Correct machine position, orientation, anchoring and levelling.

• Shaft, coupling, belt, guide or other alignment requirements.

• Bearings, lubrication lines, seals and cooling arrangements.

• Fasteners, guards, covers, access panels and removed components.

• Tooling, fixtures, sensors and parts that were separated for transport.

• Evidence of impact, corrosion, leakage or damage to vulnerable components.

Record actual results against specified tolerances. For precision machinery, levelling alone may not prove geometric accuracy; further checks may be needed for straightness, squareness, spindle condition or axis positioning.

Investigate unusual vibration or noise rather than adjusting parts until the symptom disappears. Possible causes include misalignment, looseness, imbalance or mounting issues. ISO 20816 provides relevant vibration guidance, but the applicable criteria depend on the machine.

Verify Electrical, Control and Safety Systems

Dismantling and reconnecting equipment can introduce wiring mistakes, incorrect motor rotation, missing parameters or communication faults.

Competent personnel should check the items relevant to the machine, including:

• Supply characteristics, protective earthing and electrical connections.

• Motor direction, drive settings and overload protection.

• Sensors, encoders, actuators and input/output signals.

• PLC, HMI, servo, variable-frequency drive and network communications.

• Alarm responses, recipes, operating modes and saved parameters.

• Emergency stops, guards, interlocks and other safety functions.

Compare controller and drive settings with approved backups. Document and test any intentional changes; a backup loading successfully does not prove that its parameters are correct.

Safety verification must take place before production trials. Follow manufacturer procedures, site risk assessments and applicable electrical and machinery safety requirements. Never bypass an interlock or remove a guard to make a test easier. Where a safety-related fault is found, stop the relevant test until a competent person has assessed and corrected it.

Run Staged Tests Instead of One Brief Demonstration

Stage A: Static and Pre-Start Checks

Confirm installation records, lubrication, fluid levels, guards, connections, clearances and the status of required inspections. Check that tools, transport locks and temporary supports have been removed where specified.

Stage B: No-Load or Functional Operation

Where appropriate, run the machine without production material to verify movements, controls, operating modes and basic responses. Observe for abnormal sound, vibration, leakage, overheating, alarms or unexpected movement. Record the conditions and duration of the test.

Stage C: Loaded Production Trial

Use representative material, tooling, product settings and operating conditions. Measure the characteristics that determine whether the machine can do its job: output, cycle time, product quality, repeatability, rejection rate and process parameters. Test connected equipment where the contract requires line-level performance.

Stage D: Stability Over an Agreed Period

Some defects appear only after warm-up, repeated cycles or sustained operation. Agree on a suitable trial duration based on the machine and risk. Record interruptions, adjustments and faults during the trial rather than reporting only the final successful run.

Compare Measured Results with Acceptance Criteria

The team should agree beforehand how results will be evaluated. Use manufacturer requirements, contractual specifications, applicable standards and the plant’s validated process needs. Avoid inventing a universal vibration limit, output target or accuracy tolerance for equipment that differs in design and purpose.

A simple results sheet can include:

Test	Evidence to record
Mechanical installation	Inspection results and measurements
Alignment or geometry	Actual readings and applicable tolerances
Controls and utilities	Functional checks, settings and operating readings
Safety functions	Test record and authorised sign-off
Production output	Product, conditions, run duration and achieved rate
Quality	Sample results, measurement method and acceptance limits
Faults and interruptions	Alarm, event, adjustment and corrective-action log

For a CNC machine, test-part accuracy may matter most; for a pump, flow and pressure; for a packaging line, output, fill accuracy and seal quality.

Compare like with like. If product, tooling, operators or utilities differ from the baseline, document the difference before drawing conclusions.

Manage Defects Before Signing Off

When a test fails, record the symptom, evidence, likely cause if known, corrective action, owner and retest requirement. Distinguish between a safety-critical defect, a failure against a required performance criterion and a minor documentation issue.

A practical defect register might include:

• Finding: What failed and under which test conditions.

• Evidence: Measurement, photograph, alarm record or test result.

• Responsibility: Contractor, OEM, plant team or another named party.

• Action and due date: The agreed correction and completion date.

• Retest: The test needed to confirm the problem is resolved.

• Closure: Evidence and approval from the authorised representative.

If the contract allows conditional acceptance for minor non-critical items, list them explicitly with owners and closure dates. Do not treat conditional acceptance as permission to operate equipment that has not met essential safety or performance requirements.

Make Handover Evidence Part of the Job

Before final acceptance, check that the plant has the information needed to operate and maintain the machine after the relocation team leaves.

This may include updated drawings, parameter backups, test reports, calibration records, manuals, maintenance schedules and training records.

The handover pack should identify the machine and revision or configuration tested, the test conditions, measured results, deviations, corrective work and authorised approvals.

Conclusion

Machine relocation should be accepted on demonstrated results, not on appearance or a successful power-up alone. Establish a baseline, verify the receiving site, inspect mechanical and electrical systems, test safety functions, run representative production trials and compare results with agreed criteria. Record defects and require evidence of correction before final sign-off. The right tests depend on the machine and its intended use, but the principle remains consistent: acceptance should be measurable, traceable and agreed before the move begins.
