Final answer:
In systems with blowers and extract units in AUTO, a motorized pump automatically adjusts the work based on sensor input to ensure optimal efficiency and reduce manual effort.
Step-by-step explanation:
When discussing systems that include blowers and extract units with problems (pbs) set to AUTO, one might be referring to HVAC systems, or more mechanically inclined systems like those in vehicles or heavy machinery. For instance, certain systems such as power brakes in vehicles, and equipment used in bulldozers, feature a motorized pump that performs the majority of the work. On the 'AUTO' setting, the motorized pump regulates the amount of assistance provided based on the need detected by the system's sensors; thus, reducing the manual effort required for operation. These systems are designed to automatically adjust the work done by the motors to maintain optimal performance and efficiency.
