Throttle Parameters
ThROTTLE MAx
The throttle max parameter sets the wiper voltage required to produce 100%
controller output. Decreasing the throttle max setting reduces the wiper voltage
and therefore the full stroke necessary to produce full controller output. This
feature allows reduced-range throttle assemblies to be accommodated.
Examples are shown in Figure 15 for throttle types 1 through 4, using a
nominal 5kΩ potentiometer. These examples illustrate the effect of three dif-
ferent throttle max settings (100%, 90%, 60%) on the full-stroke wiper voltage
required to attain 100% controller output.
