Application Configuration
The Application Configuration menu is where an operator will set up the controller’s Auto Start Functions and Auto
Throttle Methods, if the intended use is as an auto start and/or auto throttling controller. Depending on which
application is chosen in the menu, there are certain auto start functions and auto throttling methods hidden that are
not pertinent to the application chosen. This automatic hiding feature allows for a simpler, more intuitive controller
menu in the MPC-20. Review Application Configuration under the Menu Glossary section of this manual for the full
list and definition of each setting.
Pump All Purpose
The Pump All Purpose application houses most all auto start functions and auto throttling methods of the
controller. This application is the most versatile application thus requiring so many combinations of settings
for the operator to choose.
The auto start functions and auto throttle methods to choose from are listed below.
Auto Start/Stop Functions
Level Transducer (will require an Analog Input Setting)
Flow Transducer (will require an Analog Input Setting)
Single Contact
Local Key Start
Two Contact Maintained
Two Contact Momentary
Pressure Transducer (will require an analog input setting)
Auto Throttle Methods
Maximum RPM
Pressure Transducer
Level Transducer
Flow Transducer
Local Throttle Input (this feature throttles the engine proportionally between the minimum and
maximum RPM set points)
Center Pivot / Linear Irrigation
The Center Pivot / Linear Irrigation application houses the auto start functions and auto throttle methods
meant to be used on center pivot and linear movement irrigation applications.
The auto start functions and auto throttle methods to choose from are listed below.
Auto Start/Stop Functions
Single Contact (will require a digital input for start and stop)
Local Start Key
Two Contact Maintained (will require a digital input for start and stop)
Two Contact Momentary (will require a digital input for start and stop)
Auto Throttle Methods
Maximum RPM
Pressure Transducer (will require an analog input)
Flow Transducer (will require an analog input)
Local Throttle Input
Air Compressor
The Air Compressor application houses the auto start functions and auto throttle methods meant to be used
on all engine-driven air compressor applications. The MPC-20 allows for the compressor to start/stop and
maintain a desired pressure during operation.
