• Valve Response 1
Default Value: 100%
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: 24%
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.
• Allowable Error
Default Value: 2%
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.

ESCRIPTION
• 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 system 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.
