3.1 General Information on Setup
The tasks described in this chapter are intended to be performed by
trained and authorised service technicians for initial setup. They are
not intended to be performed by the user.
3.1.1 Conditional Control Input / Output (Control IO)
The individual programming of the wheelchair with one of the LiNX
Access Tools must be made by a qualified technician.
The LiNX system now supports conditional control IO, extending the
current always rule-based model, where a single output action is
always activated in response to a single input action. With the
introduction of conditional control IO, a qualified technician can now
create:
multiple always rules — one or more outputs are always
l
activated from a single input,
conditional rules — one or more outputs are activated from a
l
single input if the specified conditions are true,
conditional/else rules — an output is activated from a single
l
input if a specified condition is true, else (otherwise) an
alternative output is activated if the same specified condition is
false.
The benefit of conditional IO is two-fold. Firstly, a single input can now
activate multiple outputs. Secondly, control inputs can be overloaded.
Overloading is where a single input can have multiple uses, each of
which depends on specified conditions.

This means that an input can be used to activate one output if the
system is in one state or function, and then activate a different output
when the system is in another state or function. For example, a buddy
button that is used to stop a wheelchair when driving can also be used
to extend a seating motion when in a seating function.
3.2 Wiring
For safe and reliable operation, the installation of looms and cables
must follow the basic principles of power wiring.
Cables must be secured between their connectors and any point of
flexing so that flexing forces are not transferred to the connectors.
CAUTION!
Risk of Injury and Damage to the Remote
Damage to cables increases wiring impedance. A
damaged cable can potentially produce localised heat,
sparks or arcing and become a source of ignition to
surrounding flammable material.
— The installation must ensure that all power cables,
including the bus cable, are protected against damage
and potential contact with flammable materials.
NOTICE!
Cables and remote modules can get damaged if not
positioned properly.
— Route and position cables and remote modules so that
they are free from physical strain, abuse or damage,
such as snagging, crushing, impacts from external
objects, pinching or abrasion.
