A

distinction

can

be

m

ade

between

three

dif

ferent

situations:

-

rest

position

(normal

position

during

driving).

-

bleeding

leading

rear

axle

(increased

pressure

on

driving

axle).

-

ventilating

leading

rear

axle

(returned

to

rest).

Operation

of

traction

control

m

ode

is

limited

to

a

m

aximum

time:

90

seconds.

A

further

operation

of

traction

assistance

m

ay

only

be

started

after

a

pause

of

50

seconds

after

the

end

of

the

previous

operation.

By

now

adjusting

a

time

relay

(G095)

to

a

delay

time

of

60



8

seconds,

the

pause

period

is

fulfilled.

REST

POSITION

When

traction

assistance

switch

C

883

is

operated

(connection

between

contacts

5

and

1),

a

voltage

is

applied

to

connection

point

15

of

time

relay

G

095

through

fuse

E062,

wire

1221,

contacts

5

-

1

of

C

883,

wire

4563. During

normal

driving,

the

traction

assistance

switch

contact

(C883)

is

open.

The

switch

is

self-returning.

BLEEDING

L

EADING

REAR

AXLE

Pressing

and

then

releasing

the

traction

assistance

switch

activates

traction

assistance

(bleeding

leading

rear

axle).

The

time

relay

(G095)

is

now

switched

on

for

a

period

of

60

seconds.

C

ontacts

30

-

87

are

closed. The

voltage

is

now

applied

from

the

VIC

to

connection

point

1

of

B

084

through

wire

4564,

contacts

30

-

87

of

relay

G095,

wire

4562,

contacts

3

-

4

and

wire

4552.

The

V

IC

will

only

supply

a

voltage

below

the

programmed

speed.

This

activates

the

solenoid

valve

(B084),

thus

bleeding

the

bellows

of

the

leading

rear

axle.

A

s

a

result,

a

greater

load

is

placed

on

the

driving

axle

(more

traction).

When

the

60

±

8

seconds

have

elapsed,

the

connection

30

-

87

of

time

relay

G095

is

broken.

As

a

result,

the

voltage

on

valve

B

084

is

also

lost.

There

is

a

safety

mechanism

to

prevent

overload

of

the

axle.

The

proximity

switch

(E542)

monitors

the

axle

load.

When

the

m

aximum

value

is

reached,

the

proximity

switch

(E542)

is

activated

and

this

applies

a

supply

voltage

to

connection

point

1

of

relay

G

427

through

wire

4555.

Relay

G

427

is

now

energised,

thereby

breaking

contacts

3

-

4.

The

bleed

valve

(B084)

is

no

longer

activated,

so

that

bleeding

is

no

longer

performed

and

ventilation

starts

again

immediately

.
