Programming Guidelines

Make sure that all hardware components are properly installed and tested. Before you start
the programming process you should first check if the console and all sensors are working
properly.

Important Preliminary Information

Before you begin, we recommend that you review the following Programming Guidelines that
control the programming process:

☛ The key is used to power the console ON

☛ Auto & simultaneous key combination is used to power OFF (Master boom switch

must be in the off position)

☛ Holding key for 3 seconds is used to enter programming mode

☛ Pressing the key saves the current parameter and advances to the next

programming step during programming mode

☛ The value of a parameter is changed with the

key changes the parameter rapidly.

Start

To begin the programming process:

☛ Be sure the Master boom switch is “OFF.”

☛ Turn console “ON” by pressing the key. When the control console is turned on, the

software version will be displayed for approximately 5 seconds. At the same time all
LED’s will be ON.
The software version and serial number of the console will be needed when calling for
service support. The serial number is located on a sticker on the back of the console.

System Setup Mode

The System Setup Mode contains the programming steps that customize the monitor to the
sprayer or sprayer components. These include calibration steps and parameters that, once
programmed, will likely never change.

To enter the System Setup Mode:

☛ First be sure that the console is ON (if not turn it on by pressing the key and wait

until the normal display is visible).

☛ Ensure the Master boom switch is OFF.

☛ Then press and hold the key for 3 seconds to enter the Program Mode.
