Operating Console; Brake And Free-Wheel Lever - Vermeiren Sigma Gebrauchsanweisung

3.3

Operating console

CAUTION
• Be aware that the stability decreases when the wheelchair is adjusted from sitting-strait to
inclined position.
• Make sure there is enough space around the wheelchair to operate backrest and seat.
How to use the operating console is described in a specific user manual, enclosed with the
delivery of your wheelchair. If this manual is missing, contact your specialist dealer
immediately.
Put the joystick in the neutral (central) position before pressing the on/off button, otherwise
the electronics will be blocked. To release this block, switch the operating console off and
on again.
Technical protections
The operating console enables you to control all driving components and motors to adjust your
body position. For your own safety, and to prevent that the wheelchair gets damaged, movements
are monitored by the electronics. This may result in block of movement, speed decrease or
complete stop. Consult the user manual of the operating console for more information.
To avoid accidental battery run down, your wheelchair is equipped with an automatic power
shutdown system. This system switches off the operating console automatically when it is not
operated for a while. If this occurs, simply switch your console back on.

Brake and free-wheel lever

CAUTION
• Only operate the free-wheel lever when your wheelchair is turned OFF. An attendant should
operate the free-wheel lever. NEVER operate it from sitting position.
• Do not use the free-wheel mode on slopes and inclinations, see symbol on motor:
Make sure that the free-wheel lever is in its braking position BEFORE switching the
wheelchair ON. Electromagnetic brakes do NOT function if the wheelchair is in free-wheel
mode. This is indicated on the operating console. Driving is not possible.
Your wheelchair is equipped with electromagnetic brakes. The working of the brakes depends on
the position of free-wheel lever (13).
The EM brakes function automatically, only if free-wheel lever (13)
is in braking position (A), see Figure 5. In this situation, the brakes
start braking if:
•
the wheelchair is OFF;
•
the wheelchair is ON and the joystick is released.
Releasing the joystick makes the wheelchair stop gently and
activates the brakes.
Operation of free-wheel lever:
•
Turn lever clockwise (position B) to put the wheelchair in free-wheel mode. Now, the motor
is disconnected. The wheelchair can be moved manually.
•
Turn lever anticlockwise (position A) to connect the motor to the drive. This should be done
before starting the wheelchair.
