6.1 Mounting
There are numerous options available for mounting the compact remote module, such as:
l tray mount
l clamp mount
l base plate mount
The choice will depend on the type of compact remote (DX2-RJM/-LF or DX2-ACU) being installed and
its user (wheelchair occupant or attendant): for a wheelchair occupant, the tray, clamp and base plate
mount options may be suitable; for a wheelchair attendant, the tube or drop-in mount options may
be more suitable.
6.1.1 Cable routing options
The base of the remote module has two cable exit
recesses located on either side. These allow the bus
cable to extend from the remote at any angle between
vertical and horizontal.
For plate mounting options, this means that the cable
can be routed to the side of the remote module, and
above the plate, as shown in Figure 5.
l tube mount
l drop-in mount
Figure 5: Cable routing options
Warning
Limit to ten or fewer the number of times the compact remote module is installed on to a plate if the bus cable is
at 90° to the module; frequent flexing at this angle may damage the cable.

Note
The mounts shown in the following sections are suggestions only; Dynamic Controls does not manufacture or
supply the mounts. The OEM is responsible for the final design of the mount and its application.
6.1.2 Tray mount
The remote module can be mounted on to any suitable flat
surface, such as a tray, using the fixing holes underneath the
module and two M5 bolts. The maximum torque to fasten these
bolts is 3 Nm – do not exceed this rating as it may damage the
remote module.
This solution is ideal for wheelchair occupants that require the
remote module to be in a more central position, rather than the
standard placements of the left- or right-hand armrests.
Figure 6: Fi xing centres
6.1.3 Clamp mount
The compact remote has a cylindrical base which is suitable for attaching a cylindrical style clamp or
clip.
Figure 7: Clamp diameter Figure 8: Clamp mount Figure 9: Fi xing the clamp mount
6.1.4 Plate mount
The remote module can be mounted using a flat base plate (see Figure 10: Base plate example) and
two M5 bolts. The maximum torque to fasten these bolts is 3 Nm – do not exceed this rating as it may
damage the remote module.
Figure 10: Base plate example
Figure 11: Fixing the base plate
Page 16 - Installation
6.1.5 Tube mount
Figure 12: Tube mount (from above)
The tube diameter will depend on the tube clamp
used, and also the fixing hole centres on the
remote module (30 mm). A tube with an outside
diameter of 15 - 22 mm would be suitable.
Use two M5 bolts to fasten the tube between the
clamp and the base. The maximum torque to
fasten these bolts is 3 Nm – do not exceed this
rating as it may damage the remote module.
Ensure that the DXBUS cable is not pinched when
tightening the tube clamp.
GBK65701 DX2 Compact Remote Modules
Installation Manual Issue 1
The remote module can be fixed on to a tube
using a suitable tube clamp. This solution is useful
for tubes that run perpendicular to the remote
module, as shown left.
Figure 13: Fixing the tube mount
6.1.6 Drop-in mount
The depth and shape of the base of the compact remote module allows it to be placed into a suitably
designed cradle, such as the drop-in mount shown in Figure 14.
The drop-in mount is ideal for the DX2-ACU attendant remote module, allowing an attendant to
remove and replace the module with ease, and also use the module at a comfortable, safe distance
from the wheelchair. Design the mount to prevent the remote module from falling out accidentally,
or twisting around when used in the mount. A concept drawing is shown below.
Figure 14: Concept drawing for drop-in mount
Installation - Page 17
GBK65701 DX2 Compact Remote Modules
Installation Manual Issue 1
6.2 Positioning
6.2.1 DX2-RJM/-LF
Position the remote module such that a typical user's arm is in a natural, comfortable position.
:
Note
It is the responsibility of both the manufacturer and the dealer to determine the most appropriate installation
suitable for any single user. This includes, but is not limited to, the placement of the remote module for long term,
comfortable use.
For wheelchair occupants using the DX2-RJM or DX2-RJM-LF, the OEM manufacturer should consider
providing a hand guard at the front of the compact remote module to protect the user's hand against
crushing, such as when manoeuvring under a table.
Warning
If the wheelchair's remote module has not been fitted with a hand guard, the user should be made aware that
their hand will not be protected from crushing, when, for example, manoeuvring towards or under a table.
:
When positioning the compact remote, consider the position of the master remote module too. The
wheelchair occupant must be able to see the master remote display when the compact remote
module's display is switched off or when actuators are being used, since actuator feedback is only
displayed on the master remote, not the compact remote.
6.2.2 DX2-ACU
Do not install or place the compact remote module higher than 1.2 m from the ground.
To minimise the risk of snagging, Dynamic Controls recommends permanently fixing the compact
remote module to the rear of the wheelchair, when used as an attendant remote, in line with EN
12184:2009 8.6 Assistant control unit, push handles and handgrips.
For compact remote modules that are not permanently fixed to the wheelchair, limit the length of the
cable between the product and the back of the wheelchair to:
1. minimise the chance of the product hitting the floor, and being damaged if dropped;
2. minimise the chance of the joystick landing on the floor and deflecting, causing a runaway situation;
3. minimise the chance of snagging the cable on an external object.
The recommended total length of the bus cable, between the product and the back of the wheelchair,
must be no longer than the height above the ground that the product is normally placed. For an extra
margin of safety, reduce the cable length by a further 0.25 m.
:
Note
It is recommended that the low force compact remote module (DX2-RJM-LF) is not used as an attendant remote. If
the remote is dropped, the mass of the remote, relative to the joystick deflection force, makes a runaway more
likely than if the full deflection force joystick (DX2-ACU) is used.
6.3 Wiring
For safe and reliable operation, the installation of looms and cables must follow the basic principles of
power wiring.
Page 18 - Installation
GBK65701 DX2 Compact Remote Modules
Installation Manual Issue 1
Cables must be secured between their connectors and any point of flexing so that flexing forces are
not transferred to the connectors.
Warning:
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.
Warning
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.
:
Adequate strain relief must be provided for all cables, and the mechanical limits of the cables and
looms must not be exceeded.
Ensure that connectors and connector sockets are shielded from water splashes and water ingress.
Cables with female connectors should face horizontally or downwards. Ensure all connectors are fully
mated.
Warning
Connector pins on cables connected to the power module can still be live even when the system is off. Cables with
live pins should be connected, restrained or covered so that they are not exposed to human contact or materials
that could cause electrical shorts.
:
Make sure that the cables do not extend beyond the wheelchair to prevent them from being caught
or damaged by external objects. Take particular care on wheelchairs with movable structures such as
a seat raise.
Warning
Avoid routing the cable where it will come into continuous contact with the end user.
:
When installing the bus cable, avoid undue straining of the cable and connection points. Flexing of
the cable should be minimised wherever possible, to extend service life and minimise the risk of
accidental damage.
Warning
Use of a cable chain to support the bus cable, where the cable is subject to regular cyclic bending, is
recommended. The maximum stretch of the chain should be less than the length of the bus cable. The force
applied to flex the cable should never exceed 10 N.
Note
Appropriate life testing should be carried out to determine / confirm the expected service life and inspection and
maintenance schedule.

Note
Dynamic Controls recommends that you do not select ACU for the Joystick Source parameter for profiles 1 - 5.
The ACU profile is automatically selected by the master remote module when the ACU takes control of a system. If
another profile, other than the ACU profile, is selected and the profile has been configured with the ACU as the
joystick source, then the Attendant indicator will not operate—the Attendant indicator only operates with the ACU
profile.

:
Note
The following section details the operation for DX2-RJMand DX2-RJM-LF only. For a description of the DX2-ACU's
operation, see section 7.2 DX2-ACU operation .
The DX2-RJM and DX2-RJM-LF (low force joystick version)
are drop-in replacements for the DX-RJM. They are
designed to be used by the wheelchair occupant as a
secondary remote module, and connected to a DX/DX2
system via the fixed, trailing DXBUS cable.
The symmetrical design of the controller, and its trailing
lead enables the remote modules to be fitted and operated
left of the user, right of the user or anywhere in between.
The fixing holes permit a range of mounting orientations
including standard, tray, centre-line and swing-away
mounts.
Warning
Users should be aware that the surface of the remote module can potentially get hot when it is exposed to strong
sunlight for long periods.

Figure 18 shows the main components of the DX2-RJM and DX2-RJM-LF. These are described below:
o
joystick - to control speed and direction
o
power button (with status LED) - to power up or power down the system, and
view the system's status
o
mode button - to select drive profile
o
information display - displays selected drive profile
o
battery indicator - displays battery status
o
attendant indicator - displays which controller (occupant's or attendant's) has
control of the wheelchair
Note
To operate, the DX2-RJM and DX2-RJM-LF must be connected to a DXsystem via the DXBUStrailing lead.
Warning
Do not use the compact remote module if it is worn or damaged. Worn or damaged modules should be serviced
immediately, especially if the DXBUS cable, joystick gaiter or keypad are ripped, torn or damaged.
:
7.1.1 The joystick
Warning
The compact remote modules may only be used with the authorised joystick knobs. Use of any other joystick knob
requires that the installer tests and confirms that the joystick returns to the neutral position whenever the joystick
is deflected. Tests with the device mounted horizontally and with a water soaked knob (foam knobs only) are
required if the installer judges these risks as significant.
Figure 19: The joystick
If the user moves the joystick back to the neutral position, the wheelchair will slow down and stop.
:
The joystick controls the direction and speed of the wheelchair.
When the joystick is deflected from the centre (neutral) position, the
wheelchair will move in the direction of the joystick movement.
The speed of the wheelchair is proportional to the joystick deflection, so that
the further the joystick is moved from the neutral position, the faster the
wheelchair will travel.
If the user releases the joystick from any position other than the neutral position, the joystick will
return to the neutral position and the wheelchair will slow down and stop.
The joystick can also be used to wake up the system when in sleep mode — see 7.1.8 Sleep mode.
Warning
It is the responsibility of the wheelchair manufacturer to inform the wheelchair user about the wheelchair's
stopping distances.

Note
The following section details the operation of the DX2-ACU only. For a description of the operation of the DX2-
RJM and DX2-RJM-LF, see section 7.1 DX2-RJM, DX2-RJM-LF operation .
The DX2-ACU (attendant control unit) enables an
attendant to take over control of a connected DX/DX2based wheelchair. It may be permanently mounted
onto a wheelchair (normally mounted at the rear) or
may be a general purpose, floating unit, plugged into
and used with a number of DX equipped chairs.
The DX2-ACU is connected into a DX/DX2 system via
the DXBUS trailing lead, and configured with the
Dynamic Wizard and HHP.
While in attendant mode, joystick control provided by
the DX2-ACU is enabled and joystick control from the
user remote module is disabled. Conversely, when in
user mode, only the joystick control on the user's
remote module is enabled and joystick control on the
DX2-ACU is disabled. In either case, any other controls
available on the user's remote module (lighting,
actuators, etc.) are fully functional.

9.3 Fault indication 42
9.4 Dealing with compact remote module faults 42
9.1 OONAPU
OONAPU (“Out Of Neutral At Power Up”) is a safety feature that
prevents accidental movement of the wheelchair, either when powering
up, or when the wheelchair comes out of an inhibit state.
OONAPU warning
If the system is powered on (or comes out of an inhibit state) while the
joystick is not in the centre position, an OONAPU warning is displayed.
Figure 34: OONAPU sequence
During an OONAPU warning, the information display LEDs will flash continually (all on, followed by all
off) to alert the user, and the wheelchair will not drive. If the joystick is returned to the centre position
within five seconds, the warning will clear and the wheelchair will drive normally.
OONAPU fault
However, if the joystick remains out of neutral for longer than five seconds, an OONAPU fault will
occur (see note below); the fault is displayed by the status indicator flashing red, and the wheelchair
will not drive. To clear the fault, return the joystick to the neutral position and power the unit off and
then on again.
:
Note
An OONAPU fault will not be displayed if the Wizard parameter Disable OONAPUFaults is set to Yes.
An OONAPU fault will not occur if the active remote module is a DX2-ACU. Instead, if the DX2-ACU's joystick
remains out of neutral for longer than five seconds, the OONAPU warning will continue to be displayed.
9.2 Drive inhibit indication
When a wheelchair is in a drive inhibit state, the information display
switches off, and the mode button flashes at a rate of on for ½ second,
off for ½ second.
This sequence continues for the duration of the drive inhibit.
:
Note
Apart from the information display and mode button, the drive inhibit indication described above does not affect
any other indicators - all other indicators will continue to operate as normal.
Figure 35: Dri ve inhibit indication
(RJM top, ACU bottom)
Diagnostics - Page 41
GBK65701 DX2 Compact Remote Modules
Installation Manual Issue 1
9.3 Fault indication
When a fault occurs, a flash code is displayed on both the master remote module and the compact
remote module. A flash code, which is displayed on the status indicator, is a number of flashes
separated by a 1.6 second gap; the number of flashes depends on the fault. For example, one flash
represents flash code one; two flashes represents flash code two, and so on.
:
Note
Faults that affect the safety of the wheelchair will cause the wheelchair to stop, while less critical ones will be
indicated but allow the wheelchair to continue driving. Some faults will automatically clear when the fault
condition is removed (non-latched) while others are latched and must be cleared by turning the controller off,
waiting five seconds, then turning the system on again.
Faults are categorised according to their source — that is, there are local faults (those that relate to
the compact remote module), and there are system faults (those that relate to one or more system
modules). Local faults take priority with the compact remote module and so local faults will be
displayed on the compact remote module instead of system faults if both local and system faults
occur at the same time.
When there is a local fault, the power button will flash red. All other indicators will be switched off. It is
possible that the rest of the system might not indicate a fault. All local faults (faults with the compact
remote module) are displayed as:
Flash Code 1: DX Module Fault
When there is a system fault, the power button will flash red. All other indicators will continue to
operate according to their role. The rest of the system will indicate the same fault or a related flash
code. System faults are displayed according to the flash codes described in the DX System Manual.
See also
For a full list of flash codes and more information regarding system faults, refer to the DX System Manual.
:
9.4 Dealing with compact remote module faults
1. If the compact remote module does not react to a command:
l Check that the module is not in sleep mode (see 7.1.9 Lock mode 7.1.8 Sleep mode or
7.2.8 Sleep mode).
l Check that the module is not in locked mode (see 7.1.9 Lock mode or 7.2.9 Lock mode).
2. If there is no power to the compact remote module:
l Check the DXBUS connector is mated correctly.
l Replace the DXBUS extension cable (if fitted).
l Replace the compact remote module.
3. For all flash code 1 faults:
l Check the DXBUS connector is mated correctly.
l Check the profile setting:
o
If the Joystick Source parameter (see 6.4.1 User profile options) of a pro-
grammable profile has been set up for a compact remote module (either RJM or
ACU), and the compact remote module cannot be seen by the system when operating in the profile, a flash code 1 will be displayed.
Page 42 - Diagnostics
GBK65701 DX2 Compact Remote Modules
Installation Manual Issue 1
l Replace the DXBUS extension cable (if fitted).
l Replace the compact remote module.
:
Note
As it is commonplace for attendant control units to be disconnected while the wheelchair is powered up, if a DX2ACU is disconnected while the wheelchair is powered up, and the Joystick Source parameter of any of the
programmable profiles has not been set up for an ACU, then no flash code will be displayed.
Furthermore, if the DX2-ACU is disconnected when a system is operating in the ACU profile, then the system will
revert to the last selected profile and no fault will be displayed.

l It is the responsibility of the installer to make sure that accessories and cables of the vehicle do
not interfere with the operation of the controller.
l Do not use the vehicle frame as the earth return. Any electrical low-resistance connection to
the frame is a safety risk and is not allowed by international safety standards.
l To protect the wheelchair wiring from over-currents while charging, battery chargers must be
able to reduce their current output when electrically shorted.
l If the vehicle loses electric power, it is important that an attendant is able to move the vehicle
easily.
l After you have completed the installation, check it thoroughly. Correctly adjust all pro-
grammable options before the vehicle is used.
l After you have configured the vehicle, check to make sure that the vehicle performs to the spec-
ifications entered in the programming procedure. If the vehicle does not perform to specifications, reprogram it. Repeat this procedure until the vehicle performs to specifications. If
the desired operation cannot be reached, contact your service agent.
l The dealer, therapist or other agent who supplies the vehicle to the end user has the respon-
sibility to make sure that the vehicle is correctly configured for the needs of that user.
l For each individual user, the vehicle set-up and configuration should take into consideration
his or her:
o
technical knowledge, experience and education, and
o
medical and physical condition, including the level of disability and capability (where
applicable).
l It is the responsibility of the OEM and installer to make sure that the maximum driving speed
of the vehicle is limited as appropriate when the vehicle is in a mechanically unstable position,
for example when the seat is raised.
l It is the responsibility of the therapist/installer to minimise any risk of use error, including
those arising from ergonomic features and/or the environment in which the device is intended
to be used.
l Prior to handing over the vehicle, make sure that users are fully able to operate the product by
giving them appropriate training on functionality and safety features, and having them test
drive the vehicle in a safe area in the presence of their agent.
