DIAGNOSTICS
Reboot Product Controller. Allows you to reboot the product controller ECU. This will reset the controller and re-
initialize communication with the CANbus without resetting controller parameters.
Boom Pressure Relief. This procedure will activate the NCVs or section valves or open the recirculation valve for
10 seconds to relieve pressure to the product tank when the product pump is turned off. System pressure may
be monitored on the screen. Ensure the machine is in a safe area and the master switch is on prior to beginning
this procedure.
NOTE: When recirculation is configured, Boom Pressure relief will relieve pressure to the product tank
through the recirculation valve instead of dispensing product through the NCVs.
Boom Prime. This procedure will prime the boom with product by opening the section valves and NCVs. Each
section valve switch must be on, and the master switch must be turned on. The product pump will turn on and
product will dispense out the boom for the entered Section Auto-Operation Times, beginning from the
outermost and progressing inward.
PWM Health Test. This test analyzes the performance and control range of the PWM pump control valve when
equipped.
During the test, the system will automatically increase PWM duty cycle and monitor system boom pressure and
provide the control range and system output parameters. The minimum and maximum control effort values
will be calculated, and overall health will be determined. For best control, the PWM control range should be
greater than 20% and the graphed line should not have large steps where the displayed pressure is constant
during the test.
NOTE: A narrow overall range, large steps in control, or high response hysteresis (significant differences
between increasing and decreasing duty cycle performance) may result in erratic system
performance. Consult with the sprayer manufacturer if the test repeatedly shows these types of
errors.
Demonstration Mode. Allows you to simulate typical operating pressure and system flow. This is only intended
for bench-top simulation and not for use on a live machine. Failure to comply may result in product being
dispensed as the control valve may be actuated based on the simulation conditions.
Service Mode. Allows access to enhanced diagnostics and features.
CAUTION
Some residual pressure may exist in the boom or
other plumbing circuits after this action is
performed. Always wear proper personal
protective equipment and slowly open any
plumbing components when performing system
maintenance.
WARNING
Chemical will be discharged during the boom
prime procedure. Be sure the boom is fully
unfolded and in a location safe for chemicals to
be dispensed.
