4 Setup
4.1 General information on setup
The tasks described in this chapter are intended to be
performed by trained and authorized service technicians
for initial setup. They are not intended to be performed
by the user.
4.1.1 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 activated from a single input,
•
conditional rules — one or more outputs are activated
from a single input if the specified conditions are true,
•
conditional/else rules — an output is activated from
a single 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
1637425-I
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.
4.2 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 localized
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.
Risk of damage
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.
