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:

pass end stop. I.e. when continuing
after it was closed, it opens again.
