be used without batteries. The adapter can also be used to
charge the NiMH batteries in the Xtra.Remote Control.
4.1.3 Connecting the antenna
The antenna of the Xtra.Remote Control can be fastened
on the top side connector by turning clockwise. Do not
apply excessive force as this could cause damage!
Caution: Do never use the antenna as a handle. Do
not lift the Xtra.Remote control out of the carriage
bag by its antenna.
Manual Xtra.Remote Electric
Kart & Track Control System
10
4.1.4 Connecting to a Personal Computer
The Xtra.Remote Control can be connected to a PC by
means of a serial cable.
This serial link gives third parties the ability to control and
monitor the karts and track by means of a PC.
4.2 Xtra.CDI Shutdown Transponder
To be able to limit the speed of the karts from a distance,
every kart must be equipped with an Xtra.CDI Shutdown
Transponder. Karts powered by 2 engines need an
Xtra.TwinShutdown transponder.
Each Xtra.CDI Shutdown Transponder has a unique serial
number, and by using the Xtra.Remote Control it is possible
for the user to give every Xtra.CDI Shutdown Transponder a
kart number, a group number and/or track number.
Assigning a track number to the Xtra.CDI Shutdown
Transponder gives the possibility, when other kart circuits
are close by, to control the karts independently of each
other. A maximum of 4 tracks can be assigned.
Manual Xtra.Remote Electric
Kart & Track Control System
11
This gives for example the possibility to assign a kart
number 1 on every circuit, and only a Remote Control which
is also assigned to the same track will have control over this
kart.
The Xtra.CDI Shutdown transponder is standard provided
with a connection for a brake switch. If a brake switch is
connected and activated by pressing the brake pedal of the
kart, the RPM of the kart is reduced.
On the Xtra.CDI Shutdown Transponder there is also a plug
for a network connection. By means of this network
connection (future) applications or devices can be linked,
and communicate with the Xtra.CDI Shutdown Transponder.
Warning: Continuous use of the Xtra.CDI Shutdown
transponder as a speed-limiting device may degrade the
lifespan of the engine.
4.2.1 Assembly of the Xtra.CDI Shutdown
Transponder (also valid for Twin Transponders)
The Xtra.CDI Shutdown Transponder is easy to install on
the kart, by means of its V-shape based housing. It is
possible to mount the housing both on round and/or square
tubes.
Manual Xtra.Remote Electric
Kart & Track Control System
12
By means of 2 tie wraps and 2 double sided adhesive strips
it is possible to mount the Xtra.CDI Shutdown Transponder
in most cases.
Place each of the double sided adhesive strips on one of the
slanting V sides on the bottom part of the Xtra.CDI
Shutdown Transponder.
Next, place the Xtra.CDI Shutdown Transponder on a frame
tube of the kart, so that the adhesive strips keep the
Xtra.CDI Shutdown Transponder in place.
Fasten the Xtra.CDI Shutdown Transponder with 2 tie
wraps, and ensure that these cannot tremble off during the
use of the kart or by other causes.
Warning: The best way of mounting the transponder to
your kart depends heavily on your kart’s framework.
Therefore the mounting instructions mentioned above
Manual Xtra.Remote Electric
Kart & Track Control System
13
should be considered as guidelines only. Because the
transponder operates in a rough environment, every now
and then a routine check-up must be made to ensure that
the transponder is still properly fastened and shows no
visual damage.
Keep the upper part (flat part) of the Xtra.CDI Shutdown
Transponder away from any metal parts or wires and never
place it facedown towards the track concrete.
There is no kart number printed on the Xtra.CDI Shutdown
Transponder, only a serial number. Assigning a kart
number, a group number and a track number to the
Xtra.CDI Shutdown Transponder is explained in chapter
5.2.8 Menu->Shutdown tp->Assign on page 40.
Assigning the numbers is only possible when the Xtra.CDI
Shutdown Transponder is has been connected to the engine,
which is running.
When a new Xtra.CDI Shutdown Transponder is bought, the
default kart number is factory set to the last 2 digits of the
serial number.
Warning: To prevent personal injury during installation of
the Xtra.CDI Shutdown Transponder(s), the kart engine
must be turned off.
Warning: Make sure that the Xtra.CDI Shutdown
Transponder is not damaged before using the kart. In case
of an accident or when the driver steps out of the kart
please validate correct functioning of the Xtra.CDI
Shutdown Transponder.
Do not mount the shutdown transponder next to the
ignition.

4.2.3 Electrical connection of the Xtra.CDI Shutdown
Transponder (for CDI engines)
If you have one of the below mentioned engines, please use
this wiring diagram to install the Xtra.CDI Shutdown
Transponder on your kart
CDI Engines
GX 270 (U)T2
GX 390 (U)T2
The Xtra.CDI Shutdown Transponder has two cables on the
transponder. A CDI based engine does not supply enough
energy to power the transponder and has a different
electrical signal then conventional engines.
Manual Xtra.Remote Electric
Kart & Track Control System
16
The Xtra.CDI Shutdown Transponder has an additional wire
to connect to a power source. This can be the De Haardt
Xtra.Universal power coil, the battery of an electric
starter or any other 9V to 24V DC power source.
A charge coil or lamp coil without regulator and/or
battery is not a DC power source. Please contact De
Haardt to discuss the option when using a charge coil or
lamp coil directly without regulator and/or battery.
The cable eye at the end of the blue wire of the Xtra.CDI
Shutdown Transponder has to be fixed on the blank metal
(mass) of the engine with a screw.
Pull apart the 2 connectors coming from red wire on the
engine’s On/Off switch and connect these to the connectors
of the Xtra.CDI Shutdown transponder which are attached
to the brown wire.
If the brake switch is used, the connector has to be
connected to the yellow-green wire (possibly this wire has
to be extended). The maximum length of the original wire
together with the extension cable is 2 meters. The other
contact of the brake switch must be fixed on the blank
metal (mass) of the engine.
Important: Fix the mass wire of the brake switch and/or
Xtra.CDI Shutdown Transponder always on a mass point of
the engine block itself. Under no circumstances fix them on
another mass point that is on the kart (like for example a
frame tube).
Network Port:
The Xtra.CDI Shutdown Transponder is fitted with a network
port. Through this network port the Xtra.CDI Shutdown
Transponder can be connected to other on-kart electronics.
Manual Xtra.Remote Electric
Kart & Track Control System

Warning: Always put the protection
cap on the Xtra.CDI Shutdown
Transponder’s network port when this
port is not used! Be sure that the
protection cap is fully covering all
outside metal parts of the network
port connector.
It is not allowed to connect devices to
this network port which are not
approved by De Haardt!
4.2.4 Electrical connection of the Xtra.Twin
Shutdown Transponder
Manual Xtra.Remote Electric
Kart & Track Control System
18
The Xtra.Twin Shutdown Transponder has two cables.
The second cable on an Xtra.Twin Shutdown transponder is
connected in a similar way as the cable for the first engine,
and therefore not specifically described in the text below.
The cable eye at the end of the blue wire of the Xtra.Twin
Shutdown Transponder has to be fixed on the blank metal
(mass) of the Honda GX… engine with a screw.
Pull apart the 2 connectors coming from the engine’s On/Off
switch and connect these to the connectors of the Xtra.Twin
Shutdown transponder which are attached to the brown
wire.
If the brake switch is used, the connector has to be
connected to the yellow-green wire (possibly this wire has
to be extended). The maximum length of the original wire
together with the extension cable is 2 meters. The other
contact of the brake switch must be fixed on the blank
metal (mass) of the Honda GX… engine.
Important: Fix the mass wire of the brake switch and/or
Xtra.Twin Shutdown Transponder always on a mass point of
the engine block itself. Under no circumstances fix them on
another mass point that is on the kart (like for example a
frame tube).
Network Port:
The Xtra.Twin Shutdown Transponder is fitted with a
network port. Through this network port the Xtra.Twin
Shutdown Transponder can be connected to other on-kart
electronics.
Warning: Always put the protection cap
on the Xtra.Twin Shutdown
Transponder’s network port when this
port is not used! Be sure that the
Manual Xtra.Remote Electric
Kart & Track Control System
19
protection cap is fully covering all outside metal parts of the
network port connector.
It is not allowed to connect devices to this network port
which are not approved by De Haardt!
4.3 Xtra.Range Extender/Access point
The Xtra.Range Extender/Access point has a “relay” or
“repeater” approach which helps to cover large and hard-to-
reach areas and reflective corners on the race circuit.
The unit can also be used as an access point in case it is
connected to the serial port of an external device. This gives
for example third parties the ability to control and monitor
the track and karts by means of a PC.
4.3.1 Mounting of the Xtra.Range
Extender/Access point
The operating range of the Xtra.Range
Extender/Access point depends on the height
of the antenna above the ground, line of
sight, and obstructions in the line of sight.
Therefore we suggest for range extension on
outdoor circuits to mount the Xtra.Range
Extender/Access point on a mast of at least 4
meters high or on one of the track light poles.
Locate the mast(s) on (a) strategic position(s),
in the centre of the operating areas where
obstacles (like trees and buildings) in the line
of sight are at a minimum.
If you are mounting the antenna on a roof, it
must be at least 1m above the roof line.
For indoor use the Xtra.Range Extender/Access
point can be mounted for example on a fixture which
is located on a building wall or on a pole. The fixture
must provide a distance of at least 35cm between
the Xtra.Range Extender/Access point and the wall.
Manual Xtra.Remote Electric
Kart & Track Control System
20
Always position the Xtra.Range Extender in such a way that
the antenna is in vertically position and pointed to the sky.
Guideline for mounting the Xtra.Range Extender/Access
point on a pole (for illustration only):
Lift the plastic design covers of the
Xtra.Range Extender/Access point
from the aluminium housing.
The 4 fastening holes are now visible.
Note: It is not necessary to open the
housing for mounting the unit!
Mount a baseplate to the support
tube. This can be done by a bridge
support. Use self locking nuts to
prevent from loosening by vibration.
A rubber sheet of around 5mm
thickness can be used to prevent the
baseplate from bending in case of
tight tolerances between the tube
diameter and bridge support.
Fasten the Xtra.Range
Extender/Access point on a baseplate
with 4 screws (6mm diameter) and
self locking nuts. Use spacers of
around 10mm length between the
Xtra.Range Extender and baseplate.
Manual Xtra.Remote Electric
Kart & Track Control System
21
After mounting the Xtra.Range Extender on the baseplate,
put the plastic design covers back in place.
In case the support tube
must be fastened to a pole,
U-bolts in combination with
a bridge support and self
locking nuts can be used.
4.3.2 Electrical connections of the Xtra.Range
Extender/Access point
The Xtra.Range Extender can be powered by:
230 Vac mains power supply
12 Volt DC supply, like a battery, solar panel or
external dc supply.
Standard the Xtra.Range
Extender is supplied with a
230V mains power cord.
In case the unit must be
powered by a 12 Volt DC
supply, the main power cord
has to be removed.
1. First disconnect the main power cord from the
mains.
2. Open the Xtra.Range Extender/Access box, by
loosening the 4 screws on the top.
Manual Xtra.Remote Electric
Kart & Track Control System
22
3. Disconnect the green top connector of the power
cord from the circuit board connector.
4. Loosen the 2 screws on the green connector on the
cable.
5. Cut the Yellow-Green earth wire from the ring
connector. Remove the remaining ring terminal out
of the equipment housing. After removing the ring
terminal fasten the circuit board again.
6. Loosen the gland and the power cord cable can be
removed from the Xtra.Range Extender/Access point.
Once the power cord is
removed, the 12 Volt
supply cable can be
inserted through the
gland.
Connect the 12V cable
to the ‘EXT DC’
connector on the circuit
board. When the
antenna is facing
upwards, the left pin of
the ‘EXT DC’ connector
is the ‘-’ (minus), and
the right pin is the ‘+’.’
Important :
In case of powering the Xtra.Range Extender / Access point
by way of an external DC power source, the Xtra.Range
Extender DC supply cable must be fused externally
(500mA).

4.4 Xtra.(warning) Light Control Board
The Xtra.Range Extender/Access point can be extended with
a Light Control Board. By way of this board three 230V
switched outputs are created which for example can be used
to turn on and off start, stop and (sector) warning lights.
In addition the light control has 4 low voltage inputs (12
Volt), which can be used to externally control the lights.
Also by way of advanced system configuration (not
described in this manual) other functions can be assigned to
the 4 inputs.
The Light Control Board can only control the three 230V
switched outputs when the Xtra.Range Extender / Access
point is powered by 230 Volt. If the board is only used as
input device then it can also operate when the Xtra.Range
Extender is powered by the external DC input.
4.4.1 Mounting the Light Control Board
Warning: Disconnect all power sources from
the Xtra.Range Extender / Access point and
Light Control Board, when doing mounting
and installation works!
The Light Control Board can be mounted
on top of the Xtra.Range Extender /
Access point board. On the Xtra.Range
Extender / Access point are 4 spacers
mounted, on which the Light Control
Board has to be installed.
When positioning the Light Control Board on the Xtra.Range
extender board, be sure that the pin header on the Range
Extender board is on the same position as the connector on
the backside of the Light Control Board.
Manual Xtra.Remote Electric
Kart & Track Control System
25
Fixate the light controller board with the
4 plastic screws.
Do not apply excessive force since
plastic screws are easily damaged.
After the Light Control Board is mounted
on top of the Xtra.Range Extender /
Access point board, connect the input
power connector of the Light Control
Board into the socket on the Range
Extender / Access point board.
4.4.2 Wiring the Light Control Board
Once the Xtra.Light Control Board is installed, the white
power receptacle has to be connected to the white power
plug on the Xtra.Range Extender main board. This
connector is located next to the fuse. The power
connector has dual locking lances. Be sure these are
latched when the board is installed.

The Light Control Board is separately fused (6,3A/Slow). As
illustrated above, there are individual connectors available
on the Light Control Board for the 3 switched output
channels.
Before starting the wiring, cable glands have to be screwed
into the housing and securely fastened. Three M16x1.5
threaded holes are available for this purpose, which become
visible after the blanking plugs are removed.
The M12x1.5mm threaded hole is available in case a cable
must be connected to the control input of the Xtra.Light
Control module.
The cable used to connect the switched output to the lights
must at least be insulated and have a minimum of 1,0mm2
conducted area. The cable also has to be at least rated for
300/500V, with a maximum length of 50 meters.

Both external 12Vdc and 12Vac (50/60 Hz) input signals can
be used for the input.
Use a multicore (Control) cable to connect the external
inputs to the controlling device. This cable must have a
voltage rating of at least 300 Volts, with a maximum length
of 50 meters.
The controlling device must be isolated galvanically from the
mains.
Important note:
All used cable glands must always provide fixation of the
cable feedtrough up to a force of 60 Newton. Double check
time after time during maintenance.
The clamp range of the 3 M16 glands is 5.5–9mm. For the
M12 gland this range is 4–6 mm. Never feed through
cables with different diameters.
Prevent damage to the feeded through cable caused by over
fastening the dome nut on the gland body.
4.5 Xtra.Sector Control System
Using the Xtra.Sector Control System the speed of karts can
be controlled in every section (zone) of the race track. In
the case of an accident, the speed of the karts driving inside
the dangerous zone is limited automatically. Once the karts
are outside the dangerous section, the speed limit will be
released.
The same system can be used for Pit-In and Pit-out speed
control. Once a kart drives into the pit area, the speed is
automatically reduced while the other karts on the track
retain their normal speed. When a kart exits the pits, the
speed is set to normal.
Manual Xtra.Remote Electric
Kart & Track Control System
30
For circuits having 2 (or more) tracks which can be
combined into one big track, the system can change the
Track/Group settings of the Xtra.CDI Shutdown Transponder
by simply driving a kart through the ‘configuration sector’.
The Xtra.Sector Control System consists of one or more
Xtra.Sector Beacon(s) placed along the track and
Xtra.Sector Sensors mounted on every kart.
A wire is placed in a rectangular loop across the tarmac and
attached to the Xtra.Sector Beacon. This loop marks the
start of the sector. The loop/section number and function
can be easily selected on the Xtra.Sector Beacon.
The Xtra.Sector Sensor is connected to the Xtra.CDI
Shutdown transponder by means of the kart network port.
Once the kart passes the loop, the intelligent Xtra.Sector
Sensor processes the function received.
Track Sector numbering :
Every sector starts after passing the Xtra.Sector Beacon
loop as illustrated below:
Manual Xtra.Remote Electric
Kart & Track Control System
31
Sector numbering depends on driving direction as illustrated
below:
The Xtra.Sector Beacon can be configured for both driving
directions, in case a separate “Driving Direction Unit” is
used. As this unit normally is NOT supplied with the
Xtra.Sector Beacon, this function is not further explained.
4.5.1 Electrical connection of the Xtra.Sector Beacon
The LOOP wire
is placed in a
rectangular
groove which is
cut in the race
track surface.
The 10mm deep by 3mm wide groove
must ultimately be filled with silicon
or another resin.
The ends of the LOOP wire must be attached (by soldering)
to the 2 blue wires coming from the Xtra.Sector Beacon
unit. Before soldering
the loop wires, cut them
to the required length
and place the crimp
sleeves.

Once the soldering is finished position the crimp sleeves
over the solder connections and crimp the sleeves with a
heat gun.
The power for the
Xtra.Sector Beacon is
provided by an
external adapter.
Push the adapter
power plug completely
into the socket on the
Xtra.Sector Beacon. Once the plug is put correctly into the
socket, fasten the plug with its locking screw. Once locked,
the connection is water resistant.
Warning: Keep unplugged connectors (both sockets and
plugs) completely dry and clean. Never expose them to
water, fuel, oil, chemicals or any kind of dirt!
Warning: The adapter itself is NOT waterproof and not
intended for outside use. In case the Xtra.Sector Beacon
system must be used outside, the adapter needs additional
protection.
The Xtra.Sector Beacon itself is 100% waterproof once the
power plug is connected conform instructions.
4.5.2 Mounting of the Xtra.Sector Sensor
Every kart requires its own Xtra.Sector Sensor.
It is essential that the Xtra.Sector Sensor is
installed according to the descriptions below,
otherwise performance problems or even
damage can be expected.
The most important rules of installation are:
Manual Xtra.Remote Electric
Kart & Track Control System
33
The maximum distance between the loop antenna
and the housing of the Xtra.Sector Sensor is 20 cm.
For best performance the Xtra.Sector Sensor must
be mounted flat on the karts plastic floor plate in line
with the driving direction (printed arrow points to the
driving direction). Aluminum floor plates may reduce
performance.
Keep the Xtra.Sector Sensor as far as possible away
from tubes, iron or other electric conducting
materials and the karts high current conducting
cables.
It is advisable to first connect the Xtra.Sector Sensor to one
kart only, then test if it performs properly, and continue to
mount the timing transponders to all other karts.
The fixation of the Xtra.Sector Sensor can be done with 3
screws.
4.5.3 Electrical connection Xtra.Sector Sensor
On the kart, the Xtra.Sector Sensor must be connected to
the Xtra.CDI Shutdown Transponder through the network
port.
The network port is protected with a rubber cap normally.
This rubber cap has to be removed before the network
connector can be attached. Check the polarisation before
fitting the connector!
Manual Xtra.Remote Electric
Kart & Track Control System
34
Once attached double check the coupled connectors and
make 100% sure that vibration cannot loosen the
connection.
Warning: Keep unplugged connectors (both sockets and
plugs) completely dry and clean. Never expose them to
water, fuel, oil, chemicals or any kind of dirt!
Warning: Make 100% sure that vibration can NOT loosen
the network connection as this can cause several problems
like bad functioning of the system, corrosion of the network
plug and socket, etc..
