They can be identified by the presence of a “Star Quality” label affixed to the outside of the shipping carton adjacent to the serial number/Bar code label. Concern: AC mains fuse for filament transformer would fail pr

47、ematurely during normal operation when turning unit on as a result of a design change to use IEC approved fuse beginning with 1/1/97 production. Replacement with larger value fuse would solve false tripping problem but would not always provide adequate protection against damage during severe fault c

48、ondition. Corrective Action: Add two each 3A in-rush current limiters (ICLs) that have been prepared with .187” Fast-on connectors (SLME part number 97-123-23) to the filament transformer primary circuit as follows: 1. Disconnect the AC power from the unit. 2. Remove lower chassis assembly from cabi

49、net and view from bottom. 3. On the 07-319-xx AC termination PC board, remove blue and gray leads from tabs J17 and J18. 4. Add one 97-123-23 ICL assembly in series with the blue transformer lead and tab J17, and one in series with the gray lead and J18 by attaching the female Fast-on connector of ICL to the tab on the printed circuit board and the male Fast-on to transformer lead. 5. Secure the assembly with a cable tie to other AC wires so that no leads are touching other parts. 6. Replace the fuse (F2) with a
