NOTE:
Setting value too low can cause product control system to continually hunt for target application
rate�
Setting too high will cause excessive product application error and a delay in target rate being
reached�
• Press
to set spinners� Enter
appropriate settings:
• PWM Valve settings:
• “Monitor” - no PWM control
• “Control” - tries to maintain spinner speed at
all times regardless of available hydraulic flow.
Best for hydrostatic or CVT drives�
• “Hold” - Preserves last PWM signal to valve
when conveyor is deactivated� Best for
geared transmissions with gear pumps�
• PWM Frequency - Frequency that PWM control valve is pulsed at� Settings can be found from
valve manufacturer�
•
Zero Flow Offset - Represents maximum duty cycle sent to control valve without producing any
hydraulic flow from. Increase this number to hit target rate sooner.
IMPORTANT!
Setting Zero Flow Offset too high will cause spinners to overshoot Low Spinner Speeds and
could cause delay in reaching set speed� Adjust as needed in small increments�
• PWM Gain - Determines how aggressively control valve responds when making rate
adjustments� Higher value means more aggressive system response�
IMPORTANT!
Setting PWM Gain too high spinners will become erratic� Adjust as needed in small
increments�
• Set Conveyors by selecting each bin at bottom
of screen�
NOTE:
If using PWM valves instead of Servo
valved, select “PWM” from “Control Valve
Type” list and enter settings as per notes
on Spinner valves and test for accuracy�
