Trouble Shooting; Error Messages - Husqvarna DXR-310 Operator's Manual

Error messages

There are two types of error messages that can appear
on the display:
• Service messages - These messages do not
represent any direct danger for the operator or the
machine.
• Warnings - These warn of faults or safety defects
that can cause mechanical damage.
All error messages that have been acknowledged re-
main as small yellow red warning triangles in the fi eld
for service and can be accessed by bringing up the
service menu and selecting 'Warnings". The messages
are listed in order of priority, highest priority fi rst.
When a fault that has in some way restricted the ma-
chine's functions ceases, a message appears on the
display. This message must be acknowledged for the
machine to return to full functionality.
Service messages
When a service message appears on the display, the
operator is made aware of it through the work light
fl ashing three times.
The service message remains on the display until the
operator has acknowledged it. The message disap-
pears from the display and is replaced by a yellow
warning triangle in the fi eld for service. The triangle
symbol remains for as long as the message is current.

TROUBLE SHOOTING

Warnings
When an error message appears on the display, the
operator is made aware of it through the work light
fl ashing continuously. The machine is put into idling
mode in connection with the warning. If the message
is not acknowledged the horn sounds and the motor is
turned off.
The operator acknowledges the warning message by
selecting override. The light stops fl ashing and the mes-
sage disappears from the display and is replaced by a
red warning triangle in the fi eld for service. The triangle
symbol remains for as long as the message is current.
In override mode, certain machine functions can be
used up to 50%. This function is available in order to
move the machine away from hazardous environments.
