ARIATION
Zero flow offset is an operator-entered setting. Zero Flow Offset represents the maximum duty cycle that
is sent to the control valve without producing any hydraulic flow from the PWM valve. Using too high of a
Zero Flow Offset value can cause the product control system to not properly control low rates. Zero flow
offset may vary somewhat by system and by operating conditions. On the tables on the following pages,
problems and causes relating to Zero Flow Offset are listed. Use the Confirmation Techniques to
determine if this is a problem; and then follow the appropriate solution.
Error Message: Drive is slow to begin turning.
Possible Cause: Zero Flow Offset is set too low.
Confirmation Technique:
a. Turn the Master Switch off. Enter a manual ground speed and enter a new region.
b. From the Run screen, open the product application rate window, and highlight the appropriate
product. Select Manual control mode.
c. Switch the Master Switch on.
d. Press the up button one time. Now press the down button one time. If the drive is not turning, the
Zero Flow Offset is likely to be too low.
Solution:
a. Turn the Master Switch off. Enter a manual ground speed and create a new region.
b. Increase Zero Flow Offset by 2.
c. From the Run screen, open the product application rate window, and highlight the appropriate
product. Select Manual control mode.
