Calibration Assistant. The calibration assistant allows the operator to increase or decrease the PWM output
using on-screen controls and set the PWM minimum, maximum, frequency and preset values based upon
observed operation.
To use the calibration assistant mode, toggle the vehicle master switch and at least one section to the on
position. To stop PWM output at any time during the calibration process, toggle the vehicle master switch to the
off position.
Note:
Refer to the PWM Calibration Screen section on page 104 for more information on the PWM
values configured using the manual calibration mode.
Automatic Calibration. The automatic calibration mode will allow the field computer to automatically adjust
the PWM output and attempt to determine the minimum, maximum and preset values.
To use the automatic assistant mode, toggle the vehicle master switch and at least one section to the on
position. Touch the ‘Cancel’ button at any time during the calibration to stop PWM output.
The automatic calibration process may take up to two minutes to complete. Maintain sufficient engine RPM
and set the remote hydraulic flow to allow for at least 1 GPM [3.8 L/m] flow for each motor on the control
system. The field computer will display a prompt when the calibration process is complete. If the system fails to
calibrate properly, touch the ‘Re-calibrate’ to restart the calibration process.
WARNING
The PWM valve output will increase and
decrease as the up and down arrows are
selected. Keep any bystanders away from
areas where product may be expelled and
moving components when performing the
