CHAPTER 8
78 RCM - Sprayer and AIM Command FLEX™ II Calibration and Operation Manual
Notification
Low pressure shutdown
• Check if tank sump is closed. Open if closed.
• Check if tank is empty.
• Check if master valve by flowmeter is
opening. Open if closed.
•Check if pump transducer is functioning
correctly in pressure sensor readings.
• Check if boom transducer is functioning
correctly in pressure sensor readings.
• Check wiring to pump pwm valve. Make sure
connections are secure.
• Check to see if pump is turning on when
product turns on. (Go to manual mode and
ramp up DC to see if pump is working and
pressure builds with increasing control effort.)
• Check PWM MAX value is >30.
• Check PWM control range using PWM Health
Test. Overall range should be >20%.
Low tank
• Check actual vs displayed Current Tank Level.
Adjust if necessary.
• Check Low Tank Level limit and alarm value.
Adjust if necessary.
• Check Flow Meter operation, Calibration
value, and Meter Pulse/Units. Repair or
recalibrate if necessary.
• Check Fill Flow Meter or Fill Level Sensor
operation, Calibration value, and Units if
installed. Repair or recalibrate if necessary.
NCV high flow limit - multiple
• Decrease operation or turning speed.
• Check for correct target rate and pressure.
•Check for low NCV efficiency number. -
Should normally be between 90 and 105.
• Check for correct tip size for desired rate,
speed, and pressure.
• Check flowmeter calibration value, as it may
be too low.
• Check poppets for obstructions.
• Ensure all boom valves or electronic valves are
opening correctly.
• Check strainer for plugging.
•Check for leaks.
• Check for pinched hoses.
NCV high flow limit - single
• Decrease operation or turning speed.
• Check for correct target rate.
