7.10 Modification of the raised headlights code L47
If high front implements are to be mounted, it can be useful
to increase the height of the additional raised headlights
code L47. The electrical cables are long enough; it is only
necessary to make a new bracket, mounted between the
serial holder and the lights.

7.11 Road speed signal and travel dependent signal
The road speed signal and travel dependent signal comply with
ISO 16844-2.
The road speed signal (C3) can be taken from the power supply
socket in the cab (behind the driver’s seat) and also from the
implement socket at the battery box.
The travel distance signal (C4) can only be taken from the im-
plement socket at the battery box.
The speed signal (C3) is a pulse-gap modulated signal with a
pulse of t = 2 ms * 8,000 per k (k = travel pulses per km), ampli-
tude 8 V,
I
max
= 1 mA.
The distance signal (C4) provides 4 pulses per meter of travel,
amplitude 8 V,
I
max
= 1 mA .
