- Determines the percent of error that is allowed prior to the product control system making any flow rate
corrections.
- 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.
• Response Threshold
- Default Value: 3
- Determines where the control system switches between using Valve Response 1 or Valve Response 2
speed setting.
- Leaving all other valve control settings at the default value and making a small adjustment to this
setting is usually all that is required to fine tune system performance.
Decreasing this value will have the overall effect of speeding up servo valve response.
Increasing this value will have the overall effect of slowing servo valve response.

• PWM Frequency
- Default Value: 100
- The frequency that the PWM control valve is pulsed at. Typical settings range from 100 - 125. See
PWM valve manufacturer information for recommended settings.
• Gain
- Default Value: 800
- This setting determines how aggressively the control valve responds when making rate change
adjustments. The higher the value the more aggressive the response is.
• Zero 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 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.

• Valve Response 1
- Default Value: 40%
- Determines the speed of the servo valve when product control error exceeds the Response Threshold
setting.
- Decreasing the value will cause the servo valve to run slower.
• Valve Response 2
- Default Value: 8%
- Determines the speed of the servo valve when product control error is less than the Response
Threshold setting.
- Decreasing the value will cause the servo valve to run slower.
