A Function
The Control is the heart of the Level Best electronic control system. Note: Extreme care
should be exercised when working with this device. Disconnect batteries, as any short
circuit or inadvertent grounding will damage the control. The Control microprocessor
handles all of the Level Best switching functions, including the motor solenoid, 4-way
valve, and cylinder / leg valves.
All of the leveling systems electrical requirements, 12-volt power and ground, as well as
all of the necessary leveling system information is processed through the control micro-
processor. This information includes, leg position switches, ignition and park brake sig-
nals, leveling sensor and fluid pressure sensor.
