• Zero RPM Offset
Default Value: 30
This setting 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 RPM Offset value can cause the product
control system to not properly shut off. See PWM valve manufacturer information for recommended
settings.
• Allowable Error
Default Value: 2% (2% - 3% is the normal dead band setting range.)
- Too low of a setting value can cause the product control system to continually hunt for the target
application rate.
- Too high of a setting will cause excessive product application error.
• Auto Control Check Box
Default is unchecked
Checking the Auto Control check box allows you to control the spinner speed.
