Hose Reel Irrigation
The Hose Reel Irrigation application houses the auto start functions and auto throttle methods meant to be
used on hose reel irrigation systems. The MPC-20 allows for the hose reel pump to auto start with several
methods, including the Local Key Start which may be the most used in this application. The key feature of
this application is the auto throttling method. This feature allows the controller to manage the pump’s throttle
in order to maintain a pressure in the hose during irrigation.

Start / Stop Timers
The Start/Stop Timers menu provides the operator the ability to add a countdown timer and start/stop times. The
countdown timer allows for the operator to set a desired countdown time and walk away from the engine for a
controlled shutdown when the timer expires. There are eight Start/Stop Timers the operator can choose from within
this menu that allows for the specific day and hour the controller will start and stop utilizing the internal clock. Review
Start/Stop Timers under Menu Glossary section of this manual for full list and definition of each setting.
Start / Stop timers work in conjunction with other Start / Stop types. If the engine is already running from another
Start / Stop type when a Start / Stop timer occurs, the Start / Stop timer is ignored. Once the engine is started by
the Start / Stop timer, the timer has to expire for a controlled shutdown to occur.
