MMRG Series

Replace the speed adjust potentiometer with a single pole, multi-position

switch, and two or more potentiometers in parallel, with a total parallel

resistance of 10K ohms. Figures 20 and 21 show the connection of two

independent forward and reverse speed adjust potentiometers that can

be mounted at two separate operating stations.
