| Duty cycle and operating life |
| Daily operating schedule | Open hours per day × operating days per year | Example: 8 hours/day × 300 days/year = 2,400 scheduled hours/year | Test schedule showing run time, rest periods, ambient conditions, and the exact production configuration tested | Confirm the tested schedule meets or exceeds the planned site schedule. |
| Movement cycle rate | Complete programmed show cycles per hour | Example: 6 cycles/hour during an 8-hour day = 48 cycles/day | Controller log or time-stamped test record defining what counts as one complete cycle | Check that cycle counts include the full motion sequence, not just controller activations. |
| Annual cycle estimate | Cycles/day × operating days/year | Example: 48 × 300 = 14,400 cycles/year | Supplier’s tested cycle count and inspection records at stated intervals | Compare the expected annual total with the documented test exposure; do not treat a short demonstration as a life test. |
| Continuous-run and recovery test | Elapsed run time, pauses, faults, and restart behavior | Set the required test duration and rest pattern to match the intended installation | Unedited test log or video, fault list, restart records, and the test procedure | Verify recovery after scheduled stops and after a simulated power interruption, if relevant to the site. |
| Motion consistency | Repeatability of key poses, travel limits, and show timing | Define acceptable variation with the supplier before testing | Before-and-after measurements, controller settings, and inspection notes from repeated cycles | Look for drift, incomplete movement, unusual noise, overheating, or increasing cycle time. |
| Maintenance and serviceability |
| Preventive maintenance interval | Recommended inspection interval in operating hours or cycles | Require a schedule tied to hours, cycles, or both; enter the supplier’s documented interval | Model-specific maintenance manual listing inspection tasks, lubrication points, and intervals | Intervals should be clear and compatible with the planned operating schedule. |
| Routine service time | Labor hours for specified routine tasks | Set a buyer target based on staffing and access constraints | Timed service demonstration identifying tools, technicians, task steps, and access requirements | Compare like-for-like tasks; separate routine work from corrective repairs. |
| Wear parts and spares | Part number, expected replacement interval, and lead time | Request a priced spare-parts list and a stocked-parts plan for the required service period | Parts list, recommended stock quantities, availability statement, and replacement instructions | Confirm critical parts are identifiable, replaceable, and available within the buyer’s acceptable downtime. |
| Fault diagnosis | Available fault codes, logs, and troubleshooting steps | Require written diagnostic steps for the major motion, control, and power systems | Sample fault log and troubleshooting guide for the quoted configuration | Check that staff can identify a fault and determine whether it requires an on-site technician. |
| Warranty and claim verification |
| Warranty duration and start date | Coverage period and the event that starts the period | Enter the exact duration and start date rule stated in the proposed contract | Draft warranty terms covering the specific model, components, and installation | Do not rely on verbal assurances or a general brochure; confirm the signed contract controls. |
| Covered components | Named coverage for structure, actuators, controls, wiring, and supplied accessories | Require each included and excluded category to be listed | Component-by-component warranty schedule and exclusions | Check how wear parts, environmental exposure, and third-party components are treated. |
| Remedy and response process | Repair, replacement, technical support, shipping, and labor responsibilities | Agree response targets and cost responsibilities in writing | Claim procedure, required documentation, service contact route, and responsibility matrix | Clarify who pays travel, freight, labor, and removal or reinstallation costs. |
| Test-data traceability | Model identifier, test date, configuration, hours, cycles, and recorded faults | Require traceable results for the quoted model or a clearly documented equivalent | Signed test report with serial or model reference, test conditions, results, and corrective actions | Reject unsupported performance claims; ask for the underlying records and their scope. |
