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 you have this problem; and then follow the appropriate
solution.
