Common Failures
Units submitted for repair have exhibited issues where the transformer does not operate correctly, affecting both manual and robotic modes. The problem typically progresses from operational to intermittent performance, eventually leading to a complete shutdown.
Repair Approach
Repairs typically involve addressing power-related issues on the circuit board. In several cases, defective capacitors within the power supply portions of the circuit board have been identified and replaced to restore functionality. Each board is evaluated to identify and address defective components.
Testing & Quality
After repair, the unit is energized, and its control output is monitored using a shunt to verify proper DC/AC mode operations. This step verifies that both modes are restored to functionality and maintains consistent performance.
