Common Failures
Common issues reported include defective components such as relays, transistors, and thyristor modules. A common failure identified was a short in the SCR module, which affected the output block.
Repair Approach
Repairs involved replacing the defective components and performing preventative maintenance by upgrading several electrolytic capacitors. Key repairs also included addressing a damaged trace at the base of a transistor and replacing a shorted relay to restore functionality to the fields output. Further inspection was performed to verify contactor coil functionality and proper armature operations.
Testing & Quality
A thorough diagnostic process was employed, including Huntron and DMM testing to identify shorts and verify component integrity. Post-repair, the device underwent burn-in testing with a lamp load to verify consistent performance and passed functional testing. All switches and inputs were verified as operational. One corner of the casing was noted to be damaged. Co-inspection was performed to validate all repairs and testing.
