      Bently Nevada 3500/22M: Check the TDI and I/O Scope

      A 3500/22M quotation needs to distinguish the 288055-01 TDI spare from the 146031-01 Ethernet I/O module. Establish whether the maintenance task needs one component or both before comparing offers.

        Separate the references

        288055-01 identifies the standard TDI spare with USB cable; 146031-01 identifies the Ethernet I/O module.

        Check the installed arrangement

        Review the rack and I/O arrangement with the responsible engineer before accepting a supply scope.

      Why the Supply Scope Matters

      The family name 3500/22M is useful for starting an enquiry, but it does not replace a complete parts list. A quotation for the TDI alone may leave a required I/O component outside the order. Begin with the installed equipment and the maintenance task: what is being replaced, what will remain in service, and which items must arrive together?

      288055-01 and 146031-01: Two Distinct Components

      The 3500/22M is a Transient Data Interface. Bently Nevada lists 288055-01 as the standard TDI spare with USB cable and 146031-01 as the 10Base-T/100Base-TX I/O module. They are distinct components, not interchangeable names for the same item. Confirm the required hardware and software context before approving the offer.
      • TDI reference
        Record 3500/22M and 288055-01 where the standard TDI spare is required.
      • I/O reference
        List 146031-01 separately when that Ethernet I/O module is part of the requirement.
      • Supply boundaries
        Specify required accessories, offered condition, relevant revision information and any components excluded from the offer.

      Build a Checkable Supply Request

      • 01 / Installed system

        Record the existing arrangement

        Collect readable labels and photographs of the front module, rear I/O and rack arrangement. State the maintenance task.
      • 02 / Scope

        Identify what must be supplied

        Ask the engineer to distinguish the replacement TDI, any required I/O and accessories from items that will remain installed.
      • 03 / Offer

        Separate the quotation lines

        Request a full reference and quantity for each required component. Do not accept an assembly description that leaves its contents unclear.
      • 04 / Review

        Compare the offered components

        Check actual-unit identification, condition and relevant revision information against the approved scope. Resolve differences before release.
      • 05 / Timing

        Confirm each line's release conditions

        Ask for availability and estimated dispatch for each item. Decide whether split delivery is useful if both components are needed for the task.
      • 06 / Receipt

        Reconcile the complete requirement

        Match received items to the agreed list and retain their identification. Route a missing component or discrepancy to the named order contact.

      A Complete Quotation for the Required Components

      The quotation should name every required component and its inclusions. Review availability for each line, then compare the received items against the approved list so a missing I/O module or accessory does not leave the task incomplete.
      A complete reference is only useful when the supply scope is complete too.
      Use a line-by-line requirement, an approved offer and a receiving comparison to confirm the outcome.

      Three decisions before purchase

      • Sales enquiry
        Correct parts
        Am I buying the complete requirement?
        Keep 288055-01 and 146031-01 as distinct lines when both are needed. Have the engineer approve the scope and any relevant hardware or software constraints.
      • Technical review
        Delivery planning
        Will everything needed arrive in time?
        Review availability and dispatch conditions for every required line. A ready TDI does not establish that its required I/O is ready as well.
      • Delivery planning
        Responsibility
        Who resolves an incomplete supply?
        Name an order contact and agree how omitted items, identification differences and shipping exceptions will be reported and reviewed.

      Records to Keep

      • Installed labels
        Readable references for the existing TDI and I/O.
      • Approved scope
        The items to replace, retain and order.
      • Offer identification
        Photographs and details for the actual units offered.
      • Quotation
        Separate references, condition, inclusions and release conditions.
      • Delivery record
        Dispatch and tracking information for each released line.
      • Receiving comparison
        A check of the received items against the approved requirement.
      Treat 288055-01 and 146031-01 as separate components; do not assume a quotation includes both.
