DAF 95XF Тахограф


2. TACHOGRAPH

The tachograph (B501) has two supplies; one in
front of and one behind the contact relay
(G015).
The non-activated supply voltage is applied to
tachograph point 1/223 through fuse E023 and
wire 1127.
This supply voltage is meant for the clock,
among other things.
The activated supply voltage is applied to
tachograph point 3/223 through fuse E143 and
wire 1234.
De tachograph is connected to the vehicle
speed sensor (F533) through points B1 (1/271),
B2 (2/271), B3 (3/271) and B4 (4/271).
Pin B1 (1/271) represents the supply voltage for
speed sensor (4-pin 1st) (F533).
Pin B1 (2/271) is the earth connection for speed
sensor (4-pin 1st) (F533).
Pins B3 (3/271) and B4 (4/271) of the
tachograph receive two speed signals in
opposite phase.
Pin 3/225 of the tachograph supplies a pulsating
speed signal to the CTE 2-unit, connection point
18/232. For more information see system
manual.
Pin B7 (7/271) of the tachograph supplies the
same pulsating speed signal to one of the speed
limiting systems: ASL-V (D597), ASL-G (D809),
the E-gas 3-system (D591) or the
ECS-DS-system (D805). This wire may not be
interrupted or branched. All wiring connections
this wire runs through must be provided with a
seal.
There is also a speed signal (wire 3004) which
is connected to tachograph connection point
4/224 through the instrument panel (D852). This
is to connect a tachograph with speed
registration.
