Optional Variable Core Feature

Variable (soft) core feature uses the bale diameter sensor (A) and solenoid valve (B) to lower hydraulic pressure to the tension cylinders. This results in a lower density core at the center of the bale.

The baler tensioning valve block must be equipped with optional solenoid valve for variable core system to be functional.

With variable core ON, the solenoid restricts full system pressure from reaching the tension cylinders until variable core diameter setting is sensed at the bale diameter sensor.

When bale size reaches variable core diameter setting, the solenoid allows full system pressure to the tension cylinders. The bale is finished at full system pressure forming tighter, denser, outer layers.

Variable core operation can be confirmed by observing baler hydraulic pressure gauge. Pressure should increase from a low pressure indication to the preset pressure when variable core setting is reached.
