Control System; General; Remote Control; Signal Transmission - Husqvarna DXR300 Operator's Manual

General

The remote control, the electronics unit and the pilot control
valves are the main components in the control system. The
signals from the remote control are transmitted to the
machine via bluetooth or via a cable. The electronic unit in the
machine transmits the signals via the pilot control valves to
the hydraulic system by converting electric current into
hydraulic pressure.

Remote control

The machine is controlled from the remote control.
Transmission of signals is either wireless, using bluetooth, or
via a cable.
The movement of the joysticks is proportional. A small
movement means that the function moves slowly, a larger
movement increases the function's speed proportionally.

Signal transmission

Identity code
Each machine has its own unique ID code. Upon delivery the
remote control is pre-programmed with the machine's unique
ID code. The remote control can be reprogrammed, remated,
so that it can be used together with another machine. This can
be useful if a remote control should stop working. See
instructions in the section "Settings" under "Tuning" and
"Mating Bluetooth® radio modules" for information on how to
adjust the setting.
Wireless signal transmission
Wireless transmission of signals uses bluetooth technology.
Automatic frequency hopping
In the event of interference in the communication, the
frequency changes automatically to guarantee interference-
free transmission.
Signal transmission using cables
Connecting a cable shuts off the wireless communication.
When the machine is controlled by means of cables, the ID
code is suppressed and the same remote control can be used
for different machines if these have the same control system
version.

CONTROL SYSTEM

Battery

The battery is a Li-ion type. Operating time is about 8-10
hours per charge. Extreme cold impairs the battery's capacity
and operating time. Operating time is also affected by the
extent to which the display has been active.
To save the battery, the display goes into energy save mode
after 20 seconds. After five minutes of inactivity, the radio
communication is disconnected, and the remote control goes
into standby mode. Turn on the display by pressing any of the
function buttons.
A message appears on the display approx. 30 minutes before
the battery is completely flat. It is not possible to activate the
remote control if the battery capacity is too low.
Charging the battery
Before using the remote control for the first time the battery
has to be charged.
Charging time for a flat battery is approx. 2-3 hours. The diode
is red when charging starts and becomes green when the
battery is fully charged. When the battery is fully charged the
charger supplies the battery with maintenance current until
the battery is removed from the charger.
Keep the battery charger dry and protected against
temperature fluctuations.
The battery is charged also when the communication cable is
connected between the terminal and the machine. The
battery symbol on the terminal display shows the charging
status.
