Tools Menu
The ratio rate calibration value is entered as the ratio of injected chemical to carrier in ounces per gallon
[deciliters per liter].
For Example:
If the desired ratio of injected chemical concentration is 2 ounces per gallon [0.59 deciliters per liter], enter
a value of 2 [0.59] for the ratio rate cal value. Once the operation conditions in the Normal Application Mode
section on page 29 are set, the system will automatically adjust the rate of injected product in proportion
with the carrier product flow rate.
Agitator
If equipped with an injection system featuring an agitator enabled output, this option enables or disables a
chemical agitator.
PWM Smart Control
The PWM smart control feature may be enabled to allow the control system to estimate the required PWM duty
cycle for changes in vehicle speed or target rate, or when the hydraulic valve is toggled on. When this feature
is enabled, control response will be much more aggressive.
Dual Loop Control
The dual loop control feature is designed for use with low application rates and requires a pressure transducer
with a liquid application system controlled with a PWM valve. The dual loop feature uses both the flow meter
and pressure transducer to enhance the control response during operation at low application rates. The default
setting for this feature is disabled.
Standby Pressure
Note:
To enable the standby pressure feature, the product control system must have a PWM valve
controlling a liquid application system and a pressure transducer connected to the control node. If
these requirements are not met, the console will automatically disable the standby pressure
enable feature.
When enabled, the standby pressure setting will replace the ‘Preset PWM’ setting on the Valve
Calibration screen. Review the Preset PWM or Standby Pressure section on page 104.
The standby enable setting allows the operator to enable the standby pressure feature and enter a minimum
pressure value. Refer to the
Preset PWM or Standby Pressure section on page 104 for information on the
standby pressure value.
