Calculating the Calibration Values
Tiered Boom Settings
A tiered boom configuration has two or more booms stacked one directly in front of the other and may or may
not have different sets of nozzles capable of applying different rates.
Note:
Specialized pluming, cabling and a relay box are required to utilize a tiered boom configuration.
Generally, sprayers are not setup for this feature from the factory.
The boom tiers are connected to shut-off valves, which are controlled by a CAN single product control node
(P/N 063-0172-373). This configuration allows the machine to control a much wider range of application rates
than a standard, single boom configuration.
For example, a low application rate may be applied by turning on the first tier sections only. Higher application
rates may be applied by switching to the second tier booms with larger nozzles. A third and an even higher rate
can be achieved by using both boom tiers in tandem.
Note:
The spray tips used on a tiered boom system must be extended range tips. In addition, the volume
per minute of the second tier tips should not exceed 1.5 times the volume of the first tier’s tips. The
tier switching points should be set to 80% of the full flow volume for the boom tier tips.
To access the Tiered Boom Settings screen:
1.
Touch the Tools Menu icon from the Home screen.
2.
Select the Product Control icon from the System submenu.
3.
Touch the Calibration Settings button and select the Tiered Boom Settings button on the screen.
Note:
The tiered boom feature is not available in a granular control mode. Be sure that the configuration
screen is set to a control channel set to control a liquid product application.
The following settings may be configured on the Tiered Boom Settings screen:
Tier 1 Max. Set the desired maximum rate applied through the first tier boom sections.
Tier 2 Max. Set the desired maximum rate applied through the second tier boom sections.
Percent Tier Disable. The Percent Tier Disable is used to determine the percentage of the maximum tier rate
at which tiers are disabled as the required volume per minute decreases. Using a Percent Tier Disable value
allows the control valves to adjust to the target rate more quickly as the required rate decreases.
For Example:
A machine has a tiered boom configuration with the following capacities:
•
Tier 1 Capacity up to 25 GPM [94.6 L/min]
•
Tier 2 Capacity up to 38 GPM [143.8 L/min]
Using the given capacities, the following values should be entered as the Tiered Boom Settings:
•
Tier 1 Max. = 25 GPM [94.6 L/min] x 0.8 = 20 GPM [94.6 L/min]
•
Tier 2 Max. = 38 GPM [143.8 L/min] x 0.8 = 30 GPM [143.8 L/min]
