HYD THRTL MAX
The
hydraulic throttle maximum
parameter sets the throttle wiper voltage
required to produce 100% controller output. Decreasing the hydraulic 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 22 for throttle types 2 and 4. These
examples illustrate the effect of three different Throttle Max settings (100%,
90%, 60%) on the full-stroke wiper voltage required to attain 100% controller
output.
