Diagnosing Bale Size Potentiometer

The bale size potentiometer (A) is located on the left-hand side of belt tension arm. This potentiometer allows the monitor to display the real bale diameter during bale formation and to adjust the bale diameter at which the automatic wrapping cycle starts.

Test the bale size potentiometer (A) as follows:

Switch ON monitor in diagnostic mode. See "Switching On Control Monitor In Diagnostic Mode" in this Section.

Fully open the gate and secure it.

With belt tension arm in upward position, press and hold WRAP DENSITY key to check that digits (B) display:

  • "208" on 590 baler
  • "177" on 580 baler
  • "121" on 570 baler

If a lower value is displayed, readjust bale size potentiometer (A). See "Adjusting Bale Size Potentiometer" in "Service" Section.
