5 Operation
On/Off and Key Lock system
The On/Off button toggles the system power on or off provided the DX
Remote is not locked.
The Key Lock system uses a magnetic key to power the wheelchair down in
such a way to prevent subsequent unauthorised power up and driving. This
function is required for TÜV approval and operates as follows :
Arming/Disarming the locking system
To arm the locking system hold the magnetic key on or near the key symbol
on the DX Remote front panel. The system will beep and automatically power
itself down and no LEDs should be lit.
To turn the chair back on press the On/Off button. This will cause the system
to power up but the chair needs to be disarmed before it can be driven - this
waiting to be disarmed state is indicated by the flashing key symbol.
To disarm the lock put the magnetic key on or near the key symbol - this will
cause the key to stop flashing and the chair may now be driven normally. If the
wheelchair is not disarmed within one minute, the Dolphin will automatically
turn itself off.
Using the system without the lock
If locking the chair is not required simply power the chair down by pressing the
On/Off button - all indicators will go out.
To turn the system back on press the On/Off button - the system is now able
to be driven without the use of the magnetic key.
Joystick OONAPU
All DX Remotes feature Out Of Neutral At Power Up (OONAPU) detection.
If the system is powered up while the joystick is not in the neutral position, or
an inhibit condition such as a battery charger is removed, the System Status
LED flashes rapidly for either as long as the condition persists or for a
maximum of 5 seconds.
If the condition persists, after 5 seconds a DX Module Fault (Flash Code 1) is
signalled on the System Status LED, and the Remote Status LED flashes. This
is a latching fault and must be cleared by powering the system down and up
again (with the joystick in neutral).
5 Operation
7
No. 60025, Issue 5. January 1999
An OONAPU fault is also generated if the joystick source is changed. This
occurs when the Attendant / User switch on the DX-ACU is toggled or the
Drive Program is changed causing a joystick swap, while the joystick is not in
the neutral position. In these situations the fault is non-latching and the system
does not need to be powered down to clear the fault.
Drive Program Selection and Display
The Dolphin can offer up to five different Driving Programs, depending on its
configuration. (See Programming section.)
Profile Selection
Profiles can be selected using the Drive Program Select switch. Pressing this
switch will increment the Drive Program number up to the maximum
configured value. A further switch press will return the Dolphin to Profile 1.
Drive Program Display
The current Drive Program number is displayed on the 7-segment Drive
Program Display. When the ACU has control of the wheelchair, this display
is blank.
Drive Inhibit Display
A '-' is displayed on the Drive Program Display whenever the DX System is in
Drive Inhibit state, e.g. during battery charging, operation of actuators, active
Stop Switch (CLAM or TAM).
Remote Status Display
The Remote Module Status is displayed beside the 7-segment Drive Program
display. This LED will flash if there is an internal DX Remote fault, or if an
OONAPU fault has occurred.
System Status LED
The System Status LED is displayed above the On/Off switch. This LED is lit
if the system is turned on. It also flashes in groups called Flash Codes, to
indicate system faults.

Operation 5
No. 60025, Issue 5. January 1999
Lighting Control
A set of four lighting control switches, with feedback LED's, are provided to
control the Lighting System. A lighting module must be installed and enabled.
Suitable modules include: DX Combined Lighting Actuator Module (CLAM);
a DX Lighting Module (LM); or a DX Servo Lighting Module (SLM).
The Light switch toggles on or off the Head/Tail/Sidelight output,
independently of any other switch (except the On / Off switch). The Light
switch LED is lit when the lights are activated.
The Left or Right Indicator switch flashes the appropriate indicator output.
These are turned off by either pressing the same Indicator switch again, or
pressing the other Indicator switch, or the Hazard switch. Each associated LED
is lit when its matching Indicator switch is active.
The Hazard switch flashes both indicator outputs concurrently. The Hazard
LED also flashes if the Hazard LED is enabled. (See Programming section.)
The Hazard Indication can only be cancelled by pressing the Hazard switch
again.
All lighting functions will only operate with the system power on. Refer to the
relevant Installation Manual (e.g. LM or CLAM) for further lighting details.
Actuator Control
The DX Remote supports the control of up to five actuators if a correctly
configured actuator control module is present (see Programming section). For
example, a Combined Lighting Actuator Module (CLAM) can drive five
actuators or a Two Actuator Module (TAM) can drive two actuators.
The Dolphin has a set of five Actuator Select switches. Pressing an Actuator
Select switch will inhibit driving and select the appropriate actuator output as
indicated by the adjacent LED. The actuator order assigned in the Wizard as
Actuator 1, 2, 3, 4 and 5 Enable, is arranged on the Dolphin keypad as follows:
5 Operation
9
No. 60025, Issue 5. January 1999
The actuator may then be adjusted up or down with
the Joystick, by deflecting the Joystick beyond half
travel in the forward / reverse axis.
To resume driving, press the current Actuator Select
switch again to deselect. Alternatively another
actuator may be selected directly.
If the user attempts to change modes (e.g. from
driving to actuator mode) while the Joystick is
deflected, the current mode will be terminated and
the Joystick must be returned to neutral position
before the newly selected mode will operate.
The Joystick Actuator parameter must be set to ‘yes’ and the Actuator While
Drive parameter must be set to ‘no’ if actuators are to be controlled with the
Dolphin Joystick, (See Programming section). An Actuator Remote Control
(ARC) can be used to control the actuators. If an ARC is used to control the
actuators the Actuator Select switches on the Dolphin are disabled and the
Joystick Actuator parameter should be set to ‘no’.
The above information is for normal, intended operation of actuators by the
Dolphin. Other options for actuator operation are possible, dependant on
programming. See the TAM Installation Manual for full explanations.
Refer to the relevant DX Module Installation Manual for further actuator
details.
Battery Gauge Display
Battery charge level is continuously indicated by a set of ten LED's. These are
arranged in an arc from left to right as three red, four orange and three green.
The Battery Gauge provides true, useable battery capacity information, and
indicates other related battery conditions. Full battery capacity is indicated by
all ten LEDs on.

DX Dolphin Connection with the DX System
The Dolphin has two DXBUS connectors which
enables any DXBUS cable to be used to interconnect
it to the remainder of the DX system.
The Dolphin will normally be connected directly to
one of the two PM DXBUS connectors.
Two DXBUS
connectors
Note : If only one DXBUS connector is used on the Dolphin and the
remaining connector is accessible to the wheelchair user, a dummy connector
should be fitted to the unused connector. This will comply with ISO7176.

6 Installation and Testing
13
No. 60025, Issue 5. January 1999
Testing
Ensure that all DX Modules used in your DX System have been installed as
specified in their Installation Manuals. The Dolphin needs to be correctly
programmed for the appropriate wheelchair prior to testing.
A DX Remote contains the complete wheelchair system set up, from which all
DX Modules download their relevant information when the DX System is first
turned on. Refer to the later Auto Download section.
Powering Up Method
Power up the Dolphin by pressing the On/Off switch.
Power Up Response
The power up response for the Dolphin is :
! The System Status LED will come on steady.
Note : The first time the Dolphin is turned on, the System Status LED will
flash a fault. This is because the Dolphin must download its information to the
DX Power Module . Turn the Dolphin off then on to clear this fault. Refer to
the later Auto Download section.
! At least one of the LEDs on the Battery gauge will be on.
! The Mode display will indicate a number from 1 - 5.
DX Dolphin Check Sequence
Perform the following Dolphin check sequence :
1. Press the On/Off switch again and check the Power LED turns off. Press
it again to turn it on.
2. Press the Drive Program select switch a number of times. Check that the
display changes as expected.
3. Check all Lighting Buttons operate correctly.
4. Check the Key Lock system operates correctly.
5. Perform the remainder of the tests as outlined in the Testing sections of the
Installation Manuals of all other DX Modules used on the wheelchair.

7 Batteries and Charging
Battery Type
The DX System is designed to perform optimally with either Lead-Acid or Gel
Cell 24 V deep cycle batteries, rated at 20 - 120 Amp hours. The maximum
average discharge rate must not exceed half the rated capacity, in Amp hours.
High continuous discharge rates dramatically reduces the available battery
capacity. For example, at a discharge rate equal to the rated capacity, the
available capacity is 50 - 60 %. At a discharge rate of half the rated capacity,
the available capacity is 70 - 80 %..
A wheelchair that draws maximum average battery current of 20 A, requires
a battery of at least 40 Amp hours. A battery of only 20 Amp-hours, would
begin to suffer a drop in performance at about half of its available capacity.
The 40 Amp hour battery would have a full performance range of 4.5 times
greater than the 20 Amp hour battery; a 80 Amp hour battery would only
increase this range by 2.5 when compared to a 40 Amp hour battery.
Battery Charging
The battery charger socket is a 3 pin XLR type with pin configuration as
shown below. Ensure that the charger used is compatible with this pin out
before connection.

7 Batteries and Charging
15
No. 60025, Issue 5. January 1999
The wheelchair is automatically disabled from driving whenever the battery
charger is plugged in. The Drive Program will show ‘ ’ to indicate that the
wheelchair is inhibited.
Connection of the battery charger will automatically power the wheelchair, if
the wheelchair was powered down at the time of connection. This allows the
progress of battery charging to be monitored on the Dolphin battery gauge. The
wheelchair can, if required, be subsequently powered down by pressing the
On/Off switch, and charging will still proceed normally.
Battery Gauge
The Battery Gauge provides true, useable battery capacity information. A full
battery with at least 85 % of rated capacity, is represented by all ten LED’s lit.
Some new batteries can start with as little as 80 % capacity, developing higher
capacity in their early life (sometimes up to 110 %), before slowly
deteriorating over their rated life.
As the battery voltage drops, the number of LEDs lit reduces from right to left.
When only the red LEDs are lit, the available battery capacity is typically less
than 10 %. At this level and below, the Battery Gauge flashes at 1 Hz to alert
the user that the wheelchair is running on reserve capacity. The battery
capacity will reduce more rapidly in the reserve capacity range.
Battery Saver
The Battery Saver is a feature programmed into the DX Remote. When the
battery capacity is in the reserve range (below 21V), the wheelchair
performance is reduced. This is to preserve the life of the battery by
encouraging the user to recharge the battery before it becomes harmfully flat.
Operating the wheelchair with more than two LEDs of the Battery Gauge lit
will generally give normal wheelchair performance. This is provided that the
battery size and the PM program settings are matched to the wheelchair.
16
Batteries and Charging 7
No. 60025, Issue 5. January 1999
Battery Condition Warnings
A battery warning is shown by the Battery Gauge flashing its LEDs, the
number of which depends on what it currently has lit.
Battery High warning condition
This condition occurs when the battery voltage exceeds 28V, as measured by
the PM.
The cause can be :
! The wheelchair is still on charge and the batteries are full or faulty.
! The batteries are overcharged.
! The wheelchair is travelling down a slope and the batteries are full or
faulty.
The wheelchair will drive during this fault condition which will reset
automatically when the battery voltage drops below 28V.
Battery Low warning condition
This condition occurs when the battery voltage drops below 23.3V, when the
joystick is in neutral.
The cause can be :
If the Battery Gauge flashes with orange or green
LEDs lit, but the cause is not due to a Battery High
warning condition, the battery or battery wiring may
be faulty.
If the Battery Gauge flashes with just the left 3 or 4
LEDs after stopping the wheelchair, the battery may
be too small for the wheelchair type, or the battery
may be old or damaged.
The wheelchair will drive during this fault condition, but the flashing will
continue until the joystick is returned to neutral again.
A Battery Low warning normally coincides with a Low Capacity warning.
