To maintain a level position manually as the equipment moves over uneven ground is a difficult task and diverts the operater's attention from other aspects of the equipment's operation. The Automatic Tilt Controller provides an economical alternative to relieve the operator of this task. It is attached to the equipment, and continuously measures the equipment's tilt angle. When the tilt deviates from the level position, the Automatic Tilt Controller activates one of  its two electrical output signals. These electrical signals are generally used to control hydraulic solenoid valves that operate a cylinder that tilts the equipment. Hence, the Automatic Tilt Controller can tilt the equipment in either direction to correct any deviation from the level position.
The Automatic Tilt Controller is intended for use in mobile equipment that requires maintenance of a level position with respect to earth gravity. Typical applications include potato and tomato harvesters, and other equipment that must be maintained in a level position to operate correctly.

Steep Hills
If the equipment is used on a severe incline such that the hydraulic cylinder reaches its limit, the Tilt Controller will time out and release the hydraulic valve to avoid unnecessarily burdening the hydraulic system.  While the machine remains on the severe incline, the Tilt Controller will periodically briefly activate the hydraulics to counter any “sagging” due to leaky valves or seals.  As soon as the machine returns to more even ground with an incline within the mechanical adjustment range of the machine, the Tilt Conroller resumes normal operation to maintain a level position.

Accuracy and Stable Operation
How quickly the machines tilts when the hydraulics are activated depends on many factors, resulting in a wide range of speeds.  On a machine with fast response, it can be difficult to maintain an accurate level position because the machine keeps moving right past the level position after the hydraulics are turned off.  This can result in a situation where the machine constantly rocks back and forth.  The Greentronics Tilt Controller deals with this problem using a special “anticipation” algorithm that stops the hydraulics before the machine reaches the level position.  This algorithm enables the Tilt Controller to maintain a very accurate level position without the danger of generating continuous rocking.
