Not only are new controls added, but the actual mapped and projected switches now have varied style in the Turn Dial series.
At the top right of the AAR Machine's Boiler Face Plate are now eight new black Turn Dials with indicators.
The variance in style permits a greater simplification of operations and provides for a greater differentiation of controls during operations.
Marked Turn Dials with indicators are ideal for making settings and returning to the machine for repeatability. Other Turn Dials without markings are for calibrating settings abd adjusting the machine with feedback output results
