This manual contains operator, aviation unit main- tenance and aviation intermediate maintenance instruc- tions for System Analyzer Test Set, Type 60B63-5A (here in after referred to as the test set) (Figure 1-1). It in- cludes instruction for operation and replacement of parts available to the operator’s and AVUM/AVIM repairman. The repair parts and special test list is in Ap- pendix C. 1-2. Maintenance Forms, Records, and Reports. Department of the Army forms and procedures used for equipment maintenance are those prescribed by DA PAM 738-751. 1-3. Destruction of Army Materiel to Prevent Enemy Use. Refer to TM 750-244-2, Procedure for Destruction of Electronic Material to Prevent Enemy Use. 1-4. Preparation for Storage or Shipment. For administrative storage, refer to TM 55- 1500-204-25/1, AR 750-1, and Chapter 4. Section II. EQUIPMENT 1-7. Purpose and USe. The test set is designed for flight line checkout on a helicopter ac power generating system. The test set is used to monitor the major components of the ac power generating system. 1-8. Description. The test set consists of a test panel mounted in a combination case. The front face of the test panel contains lamps, switches, and connectors. The top of the combination case is removable and contains a storage area for an interconnection cable, two wrenches and a grounding cable. The interior of the test panel 1-5. Quality Assurance/Quality Control (QA/ QC). Refer to FM 55-411 for information about quality assurance and quality control. 1-6. Equipment Improvement Recommendations (EIR). EIR can and must be submitted aware of an unsatisfactory condition by anyone who is with the equipment design or use. It is not necessary to show a new design or list a better way to do a procedure; just simply tell why the design is unfavorable or why a procedure is difficult. EIR may be submitted on SF 368 (Quality Deficiency Report). Mail directly to Commander, US Army Aviation Systems Command, ATTN: AMSAV-QRF, 4300 Good- fellow Blvd., St. Louis, MO 63120-1798. A reply will be furnished to you. DESCRIPTION AND DATA contains four plug-in circuit cards, relays, and a volt- age regulator. The test set is interconnected, between the ac gener- ator of the ac power generating system and its associ- ated voltage regulator, using the cables provided. During generator testing, the internal regulator con- trols the ac generator while the controls and indicators on the test panel monitor the operation of the ac generator. During regulator testing (using a known good ac generator), the controls and indicators on the front panel check the various regulation and control function of the regulator. Using a switch on the front panel, the regulator response can be checked during simulated system faults. Lamps on the front panel Change 2 1-1
