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.

GLOW PLUGS / GLOWING / AFTERGLOWING
GLOWING
Glowing is only required if the outside
temperature is below 5
°C.
Automatic (16/232)
The automatic preglowing time is factory set to
45 seconds.
To protect the glow filaments against
overheating, the circuit of this engine type
contains a thermal protection switch (E550). The
thermal protection switch opens at 110 -125
°C.
Afterglowing
The after-glowing function is applied in Euro-2
engines. The glowing time is factory set to 120
seconds. Afterglowing is started approx.
3 seconds after loss of voltage at connection
point 45 (starting signal).
Afterglowing only takes place if:
-
Preglowing has taken place.
-
The engine speed exceeds approx.
400 rpm.
-
The supply voltage (battery voltage) to the
CTE unit exceeds 17 V.
During afterglowing the CTE unit checks both
the engine speed and the supply voltage. If the
engine speed falls below approx. 400 rpm of if
the supply voltage (battery voltage) falls below
approx. 17 V, the afterglowing is interrupted.
Glowing while starting
During a “starting” action voltage is applied to
pin 45 of the CTE-2 through wire 4002.
Depending on the condition (engine speed
exceeding (6/232) approx. 400 rpm and supply
voltage (battery voltage) (42/232) on the CTE
unit exceeding 17 V), glowing is applied during
starting on the understanding that preglowing
has taken place first.
VARIANTS
Location
21 Component E550 is not present in VF
engines.
41 Wire 4009 only applies in the case of a VF
engine.
