5. Control unit
Buttons and a joystick on the control unit enable you to activate and deactivate various
functions and settings. In this respect the diagrams of individual display screens shown
in the following operating instructions may differ from the actual displays of your control
unit.
An audible signal will also sound with various display screens, but only if this function
has been activated (see chapter 5.3.7).
5.1 Fitting and removing the control unit
A holder [65] has been fitted to your wheelchair to secure the control unit.
Push the guide rail [62] fitted to the underside of the control unit [9] into the sliding
part [63].
Secure the control unit [9] in the sliding part [63] using the locking lever [64].
Insert the plug [23] of the control unit into the socket [29] of the battery pack. The
connection is locked automatically by a magnetic closure.
The control unit is removed in the reverse sequence.
Before inserting the plug [23] in the socket [29] of the battery
pack, ensure that both parts are clean and there are no metallic
particles on them. If you detect such particles, use a dry and clean
cloth to remove them.
The control unit plug [23] is magnetic. Therefore prevent the plug
coming into contact with medical implants, electronic storage
media, bank cards or similar items.
5.2 Control unit functions
5.2.1 Switching on the system
If the two e-fix wheels have been correctly attached to your wheelchair as described in
chapter 2.1, you can now switch on the system using the control unit [9].
Do not touch
the joystick or controls of the control unit when switching the system on. If you do,
you will get an error message.
Press the on/off button [19] briefly. The system is switched on and the Alber e-fix
start screen is shown in the display [18] for about 3 seconds. The user screen illus-
trated in the adjacent diagram then appears (see chapter 5.3.1 for the meaning of the
symbols).
(The left-hand illustration may vary from the actual display on your control unit
because functions may be activated or deactivated.)
If you are not yet familiar with the e-fix and its driving characteristics you should
start by reducing the maximum speed to a minimum using the rotary switch [22] (see
chapter 5.2.6).
Using the joystick [14] you can now start the two e-fix wheels moving. However, make
sure you have read the safety instructions and precautions in chapter 3.
If the switched on wheels do not move, the system will automatically cut off after 10
minutes. For details, see chapter 5.5.
If, after switching the system on, you see an entirely different dis-
play to the one shown here, there is an error. Chapter 6 contains a
list of these with error codes.
The language selection menu only appears the first time you switch
on the control unit (see chapter 5.4). In this menu you can set
which language you wish the information in the display to be shown.
