Is your reading material too dark?
When this ABB ACS800 variable speed drive arrived with us for repair, our engineers couldn't interrogate it due to the contrast settings on the display panel.

In this quick step-by-step demo, our Technical Director, David Kerr, demonstrates how to do something so simple, but so essential to operating your drive. Here's how to change the contrast of your keypad display as demonstrated on an ABB ACS800 inverter.
