Emergency Operation
In an Emergency Situation
If an error occurs in the system then choose “Emergency limp home” to disconnect the part of the sprayer that fails.
This menu bypasses the system so all sensors are ignored. Then it
is possible to manually fold the boom, align track or operate valves
in order to drive home for service.

ATTENTION! See also “Menu 4.5 Emergency Mode” on
page 66.
DynamicFluid4 Operation When a Sensor Fails
When one of the sensor for RPM, flow or pressure fails, the system will work in a limp home mode, with reduced though
acceptable performance. One of the alarm ID’s between 140 to 147 will be triggered in the controller display. See also “Fault
Codes” on page 122.
• In the auto mode, the system will not work with 2 sensors failing, hence the operator should repair the failing sensor
as soon as possible.
• The pressure regulation can use both wheel speed sensor on trailer and GPS speed via ISOBUS.
÷
NOTE! IntelliTrack only works with wheel speed sensor.
Pressure regulation angle sensor works both as a feed back to the computer and as the end stop switch. If angle sensor fails,
the operator can continue turning regulation valve past the completely closed position.
Fail in the below sensors will cause an inaccurate calculation of the volume rate when spraying. In order to be able to end a
spray job when a sensor fails, do the following:
RPM Flow Pressure Speed Valve Angle Mode for Regulation Extra Actions for Operator
Use Use Use Use Use Full performance. None
Defect Use Use Use Use Reduced performance. None
Ignore
Defect Use Use Use Reduced performance. Setup new size when changing nozzle, see “Menu
3.4.3 Nozzle size flow at 3 bar” on page 57.
Defect Defect Use Use Use Reduced performance. Setup new size when changing nozzle, see “Menu
3.4.3 Nozzle size flow at 3 bar” on page 57.
Ignore Use
Defect Use Use Reduced performance. Setup new size when changing nozzle, see “Menu
3.4.3 Nozzle size flow at 3 bar” on page 57.
Defect Use Defect Use Use Reduced performance. Setup new size when changing nozzle, see “Menu
3.4.3 Nozzle size flow at 3 bar” on page 57.
Use Use Use Defect Use Spray at constant speed. Keep sprayer at constant driving speed.
Type in simulated sprayer speed, see “Menu 3.4.2
Simulated speed value” on page 56.
Ignore
Defect Defect Ignore Use Manual only. Adjust pressure after mechanical pressure gauge.
Ignore Ignore Ignore Ignore
Defect Manual only. Regulation valve can
pass end stop. I.e. when continuing
after it was closed, it opens again.
Adjust pressure after mechanical pressure gauge.
Check for passing end stop of valve.
Compensate for sections change.
