Specifications include, but are not limited to: E. SCOPE OF SERVICES- REQUIRED SERVICES FOR PLANNED MAINTENANCE The following list of services covers all types of equipment. Not all services are for every type of equipment. The list of services are specific to the listed type of equipment. Coverages noted in Exhibit 1: B= Scheduled Service Labor and Scheduled Service Materials 2024 Specification 17 HVAC/Metasys Control System Page 17 of 38 E= Scheduled Service Labor, Scheduled Service Materials, Repair F= Proactive Maintenance, Vibration Analysis 1. VIBRATION ANALYSIS (CHILLERS, COMPRESSORS, PUMPS & AIR HANDLERS AT COURT HOUSE FACILITY) a) Provide all equipment necessary to the analysis. b) Provide an experienced operator. c) Indicate instrumentation used and limits of the analysis, if any. d) Provide a graphic vibration signature taken in the horizontal, vertical and axial directions. e) Indicate at what locations signatures are obtained. f) Report the amplitude of vibration by velocity (inches per second) and frequency (cycles per minute). g) Indicate areas which exceed acceptable levels (.10 inches/second) of vibration amplitude, at discrete frequency. h) Provide recommended corrective action as required. i) Indicate re-analysis frequency based on results. 2. UNITARY EQUIPMENT OPERATIONAL INSPECTION IN PREPARATION The equipment will be running underload at the time of the analysis. The Contractor is to provide a JCI PC compatible microprocessor-based collector and field analyzer, and the technician will install non-invasive monitoring reference points prior to starting the analysis. The set-up data collector parameters are based on machine specific frequency/amplitudes ranges, and alarm levels. A. DATA COLLECTION RESPONSIBILITIES 1. Monitor and record operating current and full load amperage. 2. Determine running load as a percent of design load. 3. Collect vibration signatures at horizontal, vertical, axial machine locations to capture appropriate spectral components for specific chiller configuration. B. DATA ANALYSIS of RESULTS 1. Compare machine vibration signature to model-specific failure norms to detect motor/electrical, mechanical, and hydraulic conditions and defects. 2. Compare current data to prior diagnostic vibration samples to determine wear/failure trends if samples are available. C. THE REPORT PHASE 1. Report imminent failure condition to owner verbally at time located. 2. A written failure of results and recommendations will be provided to the owner, the written report will be available within ten days and will include: a) Written description of analysis procedures used to take readings. b) Classifications of severity based on scale for centrifugal chillers. c) Chiller identification data. d) Vibration data for type of system, amplitude, orientation, and severity. e) Analysis/results of specific findings based on chiller vibration analysis. f) Recommendations to include any specific actions warranted by the analysis. g) Chiller measurement diagram showing diagnostic frequencies and measurement points. h) Spectral plots indicating
