PWM Automatic Calibration
Note:
Automatic PWM calibration must be used if the PWM Smart Control feature is enabled. Refer to
Smart Control section on page 137 for additional information on the Smart Control feature.
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 'Stop Cal' button at any time during the calibration to stop PWM output.
Note:
If calibrating the PWM smart control feature, the product must be set as a granular application with
a PWM type control valve.
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 'OK' button and select 'Start Cal' again to restart the calibration process.
Manual No. 016-0171-122 Rev. I
WARNING
The PWM valve output will increase and
decrease during the calibration process. Keep
away from areas where product may be
expelled and moving components and alert
anyone around the equipment when performing
the calibration process.
