Select the signal input
There are two ways to record a reference signal for the speed controller:
Speed signal
The travel speed signal indicates the actual travel speed.
The travel speed signal must be used for cars with automatic gearboxes.
If you use the travel speed signal for cars with manual gearboxes, you
must install a deactivation system to prevent engine overspeed (see
„Using an engine overspeed protection system" on page 63).
Engine speed signal (rpm)
The engine speed signal indicates the engine speed in rpm.
The speed regulator 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
gearboxes. You must install a switch-off system to prevent engine
overspeed (see „Using an engine overspeed protection system" on
page 63).
Using an engine overspeed protection system
If a travel speed signal is used as a source on cars with manual gearboxes,
there must be an engine overspeed protection system in order to prevent
damage to the engine.
If you press the clutch while the speed regulator is activated, the speed
regulator must automatically switch off as otherwise the engine may 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 thus protect the engine.
If there is no engine speed signal, you can use the clutch switch. Install
the clutch switch on the clutch pedal (0 1, page 8) so that the speed
regulator automatically switches off when you press the clutch pedal.
