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
A
NOTICE!
On vehicles with manual transmission, an engine overspeed protection
must be installed.
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.
