Alarms Overview

View Alarms
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.
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. This should be:
• Non-Hazardous PFP: 23-25 Volts
• Hazardous PFP: 10-14 Volts
The middle line shows the voltage supplied to all
sensors connected to the Advanced Fluid Control
Module. This should be between 4.9-5.1 Volts.
The third line shows the A side pump dosing size. This
value is displayed in volumes of cubic centimeters (cc)
and is the volume pumped on the A side when the B
3A2776K
side dosing valve is off. Optimizing the restriction of the
system will keep this value small and ensure the
material is mixed well.
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 metering pump
moves. This bar graph should move from top to bottom
to match each metering pump stroke.
The state of the two reed switches in each air motor are
shown with the arrow above each vertical bar graph.
