• Allowable Error

- Default Value: 2%

- Determines the percent of error that is allowed prior to the product control system making any conveyor

RPM 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: 15

- 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.

• PWM Gain

- Default Value: 100

- This setting determines how aggressively the control valve responds when making spinner speed

adjustments. The higher the value the more aggressive the response is.

• Zero Flow 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 conveyor
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.

ESCRIPTION

• Fan Speed Cal

- Default Value: 4

- The Fan Speed Cal number is the number of pulses that are generated by the sensor during one

revolution of the spinner dish.

• 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.
