Section 10.
Precautions for Controller use
The PG and Dynamic controllers have been designed with the user safety as the prime
consideration. They incorporate many, sophisticated self – test features which search for
potential problems. If the controller detects a problem either in its own circuits, or in the
wheelchairs electrical system, it may decide to halt the wheelchair depending on the
severity of the fault. The controllers are designed to maximise the user safety under all
normal conditions.
In spite of their sophistication, the controllers cannot take into account, circumstances,
which put the wheelchair or controller outside their specified operating conditions, and
so it is important that the user follows the following precautions.
1.
Do not drive the wheelchair:
•
Beyond restrictions indicated in the user manual.
•
In places or on surfaces where a loss of wheel grip could be
hazardous, for example wet or wet grassy surfaces.
•
If the controller is damaged or other crucial components are known to
require repair.
•
If Joystick shows any signs of damage.
In the event of the wheelchair moving in an unexpected manner
release the joystick.
This action will stop the wheelchair under any circumstances.
2.
Although the controllers are designed and manufactured to be extremely
reliable and each unit rigorously tested, possibility of a system malfunction
always exists (however small the probability). Under some conditions of
detected system malfunction, the controller must (for safety reasons) stop the
chair instantaneously. If the physical impairments of the user are such that a
sudden braking action could result in a fall from the chair, it is advised that a
restraining device be fitted.
3.
It is recommended that a restraining device be used when operating the Power
Chair.
WARNING! Controller Replacing or Servicing Controllers
The controller supplied with your wheelchair is
specific to your wheelchair ONLY
and
has been programmed to suit wheelchair model and motor type attached to that
wheelchair. Under
no circumstances
should your controller be swapped with another
controller from another wheelchair without the strict guidance from your supplier.
Doing so may cause the wheelchair to drive erratically and in a dangerous manner. All
servicing and programming of controllers must be carried out by Selling Agent or
trained Technician. If your wheelchair handles poorly after servicing it may be an
