When an alarm occurs the alarm information screen automatically displays. It shows the current alarm code along with a bell icon. It also shows the alarm location with top and side views of the sprayer.

One reed switch signal is missing

Blank: No reed switch signal

There are two levels of alarms: warnings and advisories. A bell icon indicates an alarm. A solid bell icon with an exclamation point and three audible alerts indicate a warning. And an outlined hollow bell icon and a single audible alert indicate an advisory.

Advisories are notifications that require attention but not immediately. Alarms require immediate correction; therefore, sprayer operation automatically stops.

This screen also shows diagnostic information. There are three lines of data on the left side. The top line shows the power supply or alternator power supply. This should be between 23-25 Volts for power supply sys- tems and 10-14 Volts for alternator systems. The middle line shows the sensor voltage. This should be between 4.9-5.1 Volts.

The center of the screen shows linear sensor vertical bar graphs and reed switch information. The A side information is on the left and the B side information is on the right. Linear sensor position is displayed on the bar graph that goes up and down when the pump moves. This bar graph should move from top to bottom to match each pump stroke.

The state of the two reed switches in each air motor are shown with the arrow above each vertical bar graph.
