Calibration Interface

The interface will present the current calibration values:values for each function:

  • Up
    • Min
    • Max
  • Down
    • Min
    • Max
  • Swap extend/retract toggle button
  • And the Test buttons to start the calibration process

ValveGeneral Calibration Process

Press the "TEST" button correspondentcorresponding to the function to be calibrated. A new dialog will open displaying instructing to press the physical "ENGAGE" button to test the hydraulic movement. The function being calibrated and the current valve command value will be displayed.

Pressing Test will move the implement. Ensure it is clear!

Proportional Solenoid Calibration Process

Testing Calibration Values

Press the "TEST" button corresponding to the function to be calibrated. A new dialog will open displaying instructing to press the physical "ENGAGE" button to test the hydraulic movement. The function being calibrated and the current valve command value in milliamps (mA) will be displayed. 

Pressing Test will move the implement. Ensure it is clear!

Min. Threshold

By default the minimum threshold will be 0%. Increase the min. value by a small amount e.g. 5% and then perform a testing as mentioned above and observe the commanded output milliamps increasing.

The goal is to set Min. % to a value that just barely causes the hydraulic valve to open for a very slow gradual movement. This is sometimes referred to as the valve's "cracking point". We recommended increasing in increments of 5% until gradual movement is seen, then reduce by 1% at a time to find the threshold.

Max. Threshold

This threshold can be used to reduce the maximum output of the ECU, which would have a similar effect to reducing the hydraulic flow output of the hydraulic valve using tractor controls; however, this will usually only affect automatic control speeds. If a joystick is being used with COMMAND for manual control, then this max. value will also reduce the maximum output from the joystick.

For proportional solenoids, the max. % must be set such that the commanded output signal is no greater than 18008mA, or overcurrent protection may be triggered by the ECU when extending or retracting at 100%.

Adjust Max. % downward from 100 until the commanded output is roughly 1800mA to provide some padding for changes is solenoid temperature and environmental factors.
