Condition monitoring for a motor-driven fan
Plan an advisory vibration-monitoring pilot for one constant-speed motor-driven fan, with a baseline, operating context, response owners and measurable continuation criteria.
Pilot design · By Admin · Reviewed 18 October 2026. No installation, detected fault or measured saving is reported.
A maintenance team needs to notice a developing change in a motor-driven fan early enough to investigate it. The useful output is an inspected, recorded maintenance decision. A sensor notification alone does not demonstrate fault diagnosis or prevented downtime.
Set the pilot boundary
One comparable machine class
Begin with an accessible, constant-speed motor-driven fan in normal production service. Record the motor, bearings, coupling or belt, fan arrangement, mounting and usual duty. Variable-speed, intermittently loaded or hazardous-area equipment needs its own scope and competent engineering review.
Keep an accountable owner
Name the maintenance lead who reviews an alert, the operator who supplies running context, the IT/OT owner who controls access and the manager who accepts pilot costs. Keep the existing inspection and protective systems in service.
Agree the decision first
Specify what observation triggers a review, who can request inspection, and how findings reach a work order. An advisory pilot must not introduce automatic shutdown or replace machine protection without a separate engineered assessment.
Follow the observation to an action
1 · Register asset and baseline
Use a stable asset ID. Record installation condition, known faults, recent repairs and normal running states. Collect a reference across the operating conditions in scope; distinguish stopped, starting and stable running data. Do not borrow a universal vibration threshold from an unrelated machine.
2 · Capture useful measurements
A competent technician selects suitable sensor range, bandwidth, mounting point and direction for the failure modes being investigated. Record units, timestamps, sample schedule and sensor identity. Retain the reference method and calibration or functional-check evidence; these choices are equipment-specific.
3 · Preserve operating context
Keep speed or running-state context and relevant load/process notes with readings. Flag stale data, missing samples and sensor removal. A changed reading can reflect a changed duty or mounting condition, so the reviewer needs that context before attributing a fault.
4 · Transport and retain
Choose a supported wired controller path or a wireless sensor/gateway path after a site survey. Document buffering, clock handling, data export, retention and loss of network or power. OT access, remote support and update ownership belong in the approved network design.
5 · Review and investigate
Route an advisory event to the named maintenance lead. Record acknowledgement, operating context, inspection findings and any work-order reference. Track duplicate, unactionable and unresolved events; an algorithmic anomaly does not establish a specific mechanical diagnosis.
6 · Close the loop
Record action taken, parts or settings changed and a comparable post-action observation. Keep false alerts and missed opportunities in the record. Review the actual burden and outcomes before adding another machine; changing the sensor, mount or operating envelope may require a new baseline.
Define the pilot measurements
Data coverage: valid readings divided by scheduled readings while the fan is in the agreed running state. Report planned shutdowns and communications gaps separately.
Response: elapsed time from a recorded advisory event to acknowledgement, then to a documented inspection decision. Keep timestamps and unresolved events; choose the acceptable service window with the maintenance team.
Actionability and workload: events that led to a documented useful inspection finding, alongside reviewed events with no finding, review minutes and duplicate alerts. Report counts and definitions before percentages; never treat an uninspected alert as a confirmed fault.
Business result: record observed unplanned downtime, maintenance effort and total pilot cost, with operating hours and production context. A short pilot without a failure cannot establish avoided downtime or a reliable ROI.
Continue, revise or stop
Before commissioning, agree minimum data coverage, acceptable investigation effort, response ownership, export/recovery tests and the budget ceiling. Continue only when those agreed criteria are met. Revise mounting, scope or workflow when evidence is ambiguous; stop expansion if the pilot cannot support an accountable maintenance decision.
Compare implementation routes
A local controller route can keep analysis close to existing automation, but still needs compatible sensors, engineering tools and maintainable integration. A wireless route may reduce cabling work but adds radio coverage, gateway, battery and service dependencies. Obtain an exact bill of materials, software/service terms, support responsibilities and India availability from the supplier before choosing.

Prepare a requirements brief
Include the fan and motor identifiers, normal speed/duty, existing inspections, proposed failure modes, safe access arrangements, IT/OT boundaries, response owner and export needs. Avoid sending plant drawings, credentials or sensitive production records with an initial enquiry. Keep a short, non-confidential brief for supplier discussions and agree any sharing of operational details with your organization.
