Calibration Wizard, as shown. Follow the steps in the Wizard to
complete the Pressure Calibration process.
• Agitation Pressure

Sensor Calibration Wizard, as shown. Follow the steps in the
Wizard to complete the Pressure Calibration process.
Controller Settings - PWM
• PWM Frequency
The frequency that the PWM control valve is pulsed at. Typical
settings range from 100-125.
Note: See PWM valve manufacturer information for recommended settings.
• PWM Gain
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 Flow Offset
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.
Note: See PWM valve manufacturer information for recommended settings.
