Operation
Normally open switch
The Twister Pro can be used as a standard normally open switch: it will
activate when pressed down. Simply plug in the Twister Pro into a 3.5 mm
female jack on a switch-adapted device, joystick or computer.
To activate the Twister Pro, simply press anywhere on the top of the
activation surface. You will feel and hear an audible 'click'.
NOTE: The Twister Pro is by default delivered and set as a normally
open switch.
Safety button
The Twister Pro can also be configured using a dip switch on the bottom, so
that it functions as a safety button.

NOTE: The safety feature can detect if the switch is disconnected or
if the cable is in short circuit. This provides additional safety to the
device!
NOTE: This feature allows to be compliant with the ISO 7176:14-2008
§7.2.3.4 Leakage Current Test.
NOTE: This functionality is only possible when the host system
supports this.

• Please check the packaging and verify that all items are included.
• Make sure that you have all the necessary documentation and
knowledge to install this device.
• Check the condition of the device.
Installation Plan

users' needs and capabilities, this plan should take into account:
• Where which part of the device should be placed.
• How the device will be operated.
• A robust and reliable positioning. Hard or sudden movements of the

WARNING: Make sure that loose parts of the cable are out of reach to
avoid strangulation or other injuries.
CAUTION: Long periods of repetitive motion using the product may be
associated with nerve, tendon or muscle injury in your hands, wrists,
arms, shoulders, neck or back. See a qualified health professional for
pain, numbness, weakness, swelling, burning, cramping or stiffness.
CAUTION: Do not pull or wrap the cable around the device.
Installation
1 Define the position of the device. Make sure that it is easily accessible to
the user.
2 The device should be mounted on a flat surface. It should be mounted
securely with consideration for minimal risk of jamming or blocking
(access to) the device.
NOTE: Use the delivered screws for surfaces with a thickness of up
to 2 mm. If you use a thicker surface, be aware that the depth of
the insert is 3 mm max.
3 The connector jack should stay clean and needs to be inserted
completely into the device.

Adjusting the dip switch
Adjust the dip switch by following these steps:
1 Disconnect the switch.
2 Remove the rubber insert on the bottom of the device.
3 Configure the dip switch by using a small screwdriver (see positions
below).
4 Reapply the rubber insert.
CAUTION: If the rubber insert is not fitted correctly or even at all,
this can compromise the waterproofness of the device.
POSITION FUNCTIONALITY
Default position: compatible with
default systems which require a
normally open connection.
R-net resistor values: Compatible
with Curtiss-Wright specifications
for the CJSM II and Omni II.

External configuration
In order for the safety switch functionality to work, some parameters of the
wheelchair electronics need to be set correctly:
•Curtiss-Wright R-net parameters on page 16
•Dynamic Controls parameters on page 17
Curtiss-Wright R-net parameters
For more information, please refer to the Curtiss-Wright manual SK77981-14

Controls > Global > External Profile Jack Detect
VALUE DESCRIPTION
Off The Twister Pro will function as a normally open switch.
On The Twister Pro will be able to detect both open-
and short-circuits in the wiring. If such conditions are
detected, the function associated with the External Pro-
file Switch Jack will be disabled and a warning will be
displayed on the screen.

VALUE DESCRIPTION
Off The Twister Pro will function as a normally open switch.
On The Twister Pro will be able to detect both open- and
short-circuits in the switch itself or its wiring. If such
conditions are detected, a trip will occur.
Limp The Twister Pro will be able to detect both open- and
short-circuits in the switch itself or its wiring. If such
conditions are detected, the system will still allow Drive
but at a reduced speed and will issue a visual and audi-
tive warning.
Dynamic Controls parameters
For more information, please refer to the GBK54036 LiNX Systems Installation
Manual.

Twister Pro Installation manual 17

LiNX control inputs recognize a number of distinct resistor bands. For each
band, a different action can be selected (e.g. driving, actuator motions,
profile and function navigation and lighting).
Control inputs can be configured to monitor for errors, such as short circuit,
invalid open circuit, missing or unreliable states.
mo-vis has chosen resistor bands 1 and 10: the Twister Pro can perform
monitoring function in these bands, when the dip switch is set to the right
values (see Installation on page 12 ).
NOTE: This setting is only accessible with a LiNX Access Key DLX-
HKEY-02.
