Technical descriptionMS880
6Technical description
6.1Function description
When used as a cruise control, MagicSpeed MS880 keeps the preset speed of your
choice as constant as possible. The system compares the actual speed to the set
speed and corrects the actual speed as necessary.
The activation speed of the cruise control is about 40 km/h.
MagicSpeed is comprised of an electronic module and a cable set. The electronic
module is connected to a control element (accessory) with which you can make the
required settings. The control element is fitted in the dashboard area.
The system is equipped with various safety features for your protection.
6.2Connection options
MagicSpeed MS880 can process either a digital speed signal from the CAN bus
(CAN bus connection) or an analogue speed signal (analogue connection). A CAN
bus connection is not possible in all vehicles with a CAN bus.
NOTE for vehicles with CAN bus
I
•You can find out whether a CAN bus connection is possible for your
vehicle from the vehicle-specific product overview on our homepage, or by calling to enquire (see rear page of the manual for
contact data).
•If your vehicle features a CAN bus, but a CAN bus connection is not
possible according to the vehicle list, MagicSpeed MS880 must be
connected using a analogue connector. This will require the speed
signal to be received in analogue form.
If the speed signal is only available on the CAN bus in digital form,
you will require the CAN bus interface MagicSpeed CBI150 for the
installation of MagicSpeed MS880. This converts the digital speed
signal from the CAN bus into an analogue one.
•A CAN bus interface is not required for the CAN bus connection.

6.3Safety features
NOTICE!
A
The cruise control is equipped with numerous safety features to switch it off if any of
the following situations arise:
•The brake is applied hard
•Pressing the clutch pedal
•Pressing the accelerator and brake pedal at the same time (savior function)
•The ON/OFF button on the control element is pressed
•The engine overspeeds
•Braking to 50 % of the set speed
•Accelerating to 150 % of the set speed
If your vehicle has a steering wheel lock, make sure that it is not activated
when the key is in the ignition or a gear is selected.
•Increases the engine speed by 150 %
•Decreases the engine speed by 75 %
•The ignition is switched off
NOTE
I
The cruise control also switches off if there are problems with the brake lights, such
as:
•Defective brake lights
•A defective fuse
•A loose connection to the brake light switch
In an emergency (e.g. accelerator sticks), you can use the savior function. It is
activated by pressing the accelerator and the brake pedal at the same time. It is
deactivated when the brake pedal is released. The savior function switches the
accelerator to idle electronically, it does not apply the brake. Therefore, keep the
brake pedal pressed down until the vehicle stops.
If MagicSpeed ever fails to react to one of these occurrences, you can
always switch off the ignition.
To guarantee safe and economical operation, never use the cruise control in
congested traffic or on wet, slippery roads.

Brown and brown/white
NOTE
I
➤ Connect the brown cable and the brown/white cable to the brake light switch
(fig. 9 1, page 7).
If there are more than two cables leading from the brake light switch, this is how to
identify the two cables you need:
➤ Use a voltmeter to measure the voltage on the cables.
One of the two original cables on the brake light switch should have a
permanent positive voltage (terminal 30, 12 V) or a connected positive voltage
(terminal 15).
Both these cables must only be connected when there is an analogue
connection.
They are not required for the CAN bus connection. In this case, insulate
the ends and store them.
The second original cable should have a voltage of +12 V when the brake is applied. As soon as the brake pedal is released, no more voltage should be on
that cable.
If you cannot measure a full +12 V on the brake light switch, you vehicle probably has
a digital brake system.
In this case, connect the two cables as follows:
➤ Connect the brown/white cable to a fuse-protected, connected positive
terminal (terminal 15).
➤ Connect the brown cable to the original cable leading to the brake lights.
The voltage on this cable is +12 V with the brake applied, and 0 V with the brake
released. You will find these cables directly at the rear lights or in the wiring
harness at the rear of the vehicle.

Connecting the electrical power to MagicSpeedMS880
Yellow and blue
NOTE
I
The yellow cable and the blue cable are for connection to the travel speed and
engine speed signals respectively:
•Blue:
Records the engine or travel speed signal with a voltage between 1.5 V and 24 V
and a frequency between 6 Hz and 8.5 kHz.
Use the blue cable for speed signals whose voltage and frequency are within
above-mentioned ranges.
•Yellow:
Records the engine speed signals with a voltage between 6 V and 250 V and a
frequency between 6 Hz and 488 Hz.
Both these cables are only connected when there is an analogue
connection.
They are not required for the CAN bus connection. In this case, insulate
the ends and store them.
Use the yellow cable to record engine speed signals with a voltage of more than
20 V or when engine overspeed protection is required.
NOTE
The signal input depends on the vehicle's transmission.
I
When connecting the blue and yellow cables, there are various parameters to take
into account, which are described in the following sections:
•Which signal input do you wish to use (page 23)?
•Do you need engine overspeed protection (page 23)?
•Does your vehicle have automatic transmission (page 24)?
•Does your vehicle have manual transmission (page 24)?
•Where do you wish to record the speed ( Diagnostic manual)?
•Where do you wish to record the engine speed ( Diagnostic manual)?
•What are the voltage and frequency of the signal ( Diagnostic manual)?
NOTE
You can find a diagnostics manual on our homepage.

22
EN
MS880Connecting the electrical power to MagicSpeed
Selecting the signal input
There are two ways to record a reference signal for the cruise control:
•Speed signal
The travel speed signal indicates the actual travel speed.
The travel speed signal must be used for vehicles with automatic transmission.
If you use the travel speed signal for vehicles with manual transmission, you must
install a deactivation system to prevent engine overspeed (see chapter “Using
engine overspeed protection” on page 23).
•Engine speed signal (rpm)
The engine speed signal indicates the engine speed in rpm.
The cruise control can identify the travel speed using the engine speed as long
as you do not shift gear.
The engine speed signal is only suitable for vehicles with manual transmission.
You must install a switch-off system to prevent engine overspeed (see chapter
“Using engine overspeed protection” on page 23).
Using engine overspeed protection
NOTICE!
A
If a travel speed signal is used as a signal source on vehicles with manual
transmission, there must be an engine overspeed protection system in order to
prevent damage to the engine.
If you press the clutch while the cruise control is activated, the cruise control must
automatically switch off as the engine may otherwise be damaged.
There are two types of engine overspeed protection system:
•If you use the blue cable to transmit the speed signal, you can connect the yellow
cable to transmit the engine speed and therefore ensure the engine is protected.
•If there is no engine speed signal, you can use the clutch switch. Install the clutch
switch on the clutch pedal (fig. 8 1, page 7) so that the cruise control switches
off automatically when the clutch pedal is pressed.
On vehicles with manual transmission, an engine overspeed protection
must be installed.
23
EN
Connecting the electrical power to MagicSpeedMS880
Vehicles with automatic transmission
NOTICE!
A
No additional overspeed protection is required for vehicles with automatic
transmission.
➤ Connect the blue cable to transmit the speed signal.
Vehicles with manual transmission
➤ Connect the blue cable to the travel speed signal.
➤ Connect the yellow cable as overspeed protection using the engine speed
signal or the clutch switch.
Never use an engine speed signal. Otherwise the system will not switch
off when the transmission declutches. The engine could overrun and be
damaged!
Alternatively, you can:
•Connect the blue cable to the engine speed signal, or
•Connect the yellow cable to the negative terminal end of the ignition coil
(terminal 1).
With this solution, no additional overspeed protection is required because the
engine speed is monitored by the speed regulator. If you use the engine speed
signal, the activation speed of the speed regulator depends on the gear the vehicle
is currently in.
8.2Connecting the vehicle-specific cable set
You must connect the electronic module to the accelerator pedal using a
vehicle-specific cable set (not supplied).
NOTICE! Risk of damage!
A
Do not connect the green cable of the main wiring harness to the earth.
The earth connection is made via the accelerator cable set.
➤ Cut the the original connection of the accelerator pedal.
➤ Connect one end of the vehicle-specific cable set to the accelerator pedal.
➤ Connect the other end of the vehicle-specific cable set to the loose end of the
original connection.
➤ Insert the 8-pin plug into the appropriate socket on the electronic module.

connection
Step 1 (synchronisation)
➤ Press and hold the SW1 button on the rear of the electronic module.
➤ Switch on the ignition.
✓ You will hear two high-pitched signals.
➤ Let go of the SW1 button.
➤ Manual transmission: Apply the brake and clutch pedal and keep both
pressed down.
➤ Automatic transmission: Apply the brake pedal and hold it down. Put the gear
into neutral.
➤ Press the SET button on the control element.
✓ The LED on the electronic module starts flashing.
✓ The electronics start to synchronise with the vehicle automatically.
✓ When the synchronisation is complete, you will hear three high-pitched signals.
✓ The LED on the electronic module lights up permanently.
➤ Manual transmission: Remove your foot from the brake and the clutch pedal.
➤ Automatic transmission: Remove your foot from the brake pedal and put the
gear into neutral.
NOTE
I
✓ After successful synchronisation, the electronics automatically continue with
step 2 (pedal test).
If you do not hear three high-pitched signals, check the connections
to CAN high (blue cable) and CAN low (blue/white cable) and check
whether MagicSpeed MS880 can be connected to the CAN bus in your
vehicle according to the vehicle list.

Step 2 (accelerator pedal test)
➤ Press the accelerator pedal slowly as far as it will go and let it return the same way
slowly as far as the neutral position.
✓ While this happens,you will hear acoustic signals which signify the various
positions:
–Neutral position (idle):
–50% position:
–100% position:
NOTE
I
•If a low-pitched signal does not sound or you hear a high-pitched
signal during the pedal test, this step has failed and programming
must be repeated from step 1.
•Some accelerator pedals do not provide sufficient electric signals
when fully pressed down. In this case, only press the pedal approx.
three-quarters of the way down in step 2, as otherwise the test will
not be successful.
Step 3 (quit synchronisation)
➤ Switch the ignition off.
✓ Normally, your cruise control should be ideally preset for your vehicle.
Refer to the figure on page 29 for a summary of the CAN bus connection and pedal
test.
