to act as a control for the condition selected.
B. SEPARATE EXCITATION HANDLE
When separate excitation is desired this handle is
provided to establish that condition at any notch of the Main
Handle. Also, once that separate excitation has been
established, the Separate Excitation Handle can be moved
to provide either braking effort or tractive effort.

handle which cannot be moved unless the Main Handle
and Separate Excitation Handle are in Off position and
