Can This ABB Control be Repaired? What’s Inside a Control Anyway?

ABB controllerCan legacy controllers be repaired? Is it worth the cost? The answer to these questions are, in most cases, YES!

Here’s a perfect example of a recent successful repair of a “legacy” control – ABB control p/n PM554-RP-AC repairs. This relatively simple control repair means that our marine management customer now has a fully functional controller back in service!

What went wrong inside this ABB control?

The control would not show that power was available and would not operate. Our customer confirmed that the power supply had power available so the problem was identified as the control.

Even quality equipment like this ABB control develop problems over time from aged components, especially in a harsh marine environment. The capacitors were bad, as is often the case. Also needing replacement were the voltage regulator, and a PWM IC. Trace repairs and a good cleaning, followed by testing and this ABB control was ready to go back to work!
