6.4.3 Configuring the Transducer
With a transducer connected, the CP1000 can be configured to throttle the engine or motor to maintain a specific
transducer level much like a car’s cruise control. If this cruise control feature is desired, the Maintain Transducer
Level should be set to Enabled.
The other choice is to Disable the Maintain Transducer Level, which follows the Ramp Profile described in the
The transducer’s cruise control function can be independently set to either Low to High or High to Low.

Some applications are slow to respond to throttle changes while others are fast. An analogy is a car’s cruise
control and how the car reacts going downhill or uphill. Going downhill, a car will quickly speed up when just a
little more throttle is applied. In this case, the throttle adjustment should be less aggressive. On the other hand, a
car going uphill will speed up slowly and therefore needs more aggressive throttling. To adjust how quickly the
control panel ramps the throttle up or down for a particular application, go to the
Autostart

menu. The higher the number, the more
aggressive or quicker the control panel ramps the throttle up or down to maintain the level.
When adjusting the Throttle Aggressiveness, it is best to understand how responsive the system is to changes.
Like the analogy of the car going downhill, a small water tank with a large pump is an example of a system that
will respond quickly to changes when throttling the water level. Alternatively, a large tank with a small pump will
respond more slowly.
