3.1.1. Air Couplings
The main connection between the truck
and trailers is air couplings.
Generally, 3 different types of air cou-
plings are used in the trailers. These 3
types of air couplings have the same
function but with different shapes and
connections. There are 2 different air
supply lines in the system.
Brake Line (Yellow)
Supply Line (Red)
Service Line: Pneumatically air hose
which will feeds the brake line.
Supply Line: Pneumatically air hose
which will feeds the air tanks and trailer
According to the type of vehicle, your ve-
hicle can be equipped with one or two
different types of air couplings.
•Standard Couplings (Palm)
•Duomatic Coupling
•C (UK) Couplings

17 / 123
If your vehicle is equipped
with 2 different types of coup-
lings, you must use only one
type at the same time.
When the couplings are
mounting/demounting, the
parking brake of the truck and
trailer must be engaged.
If the brake parameters are
modified, your vehicle's brake
calculation might be non-sui-
table for regulations. Only aut-
horized services must service
to the EBS modulator.
Only authorized services and
personnel should make servi-
ce operations for the brake
system.
There might be test points on the chassis
or above the air couplings. When you re-
move the test points rubber protection
parts and push the points you can check
the air pres-sure on the brake lines.

clean and durable.If necessary,
clean/change the air coupling.
•Push the arm and mount the cou-
pling (1).
The coupling filters must be
clean regularly.

3.1.2. Compressed Air Tanks
Pressured air can be stored in the air
tanks.
The quantities and capacities of the air
tanks can be changed according to your
vehicle specifications.
In cold periods of the year or when the
air humidity is high, the moisture in the
air can be condensed and collected in
the compressed air tank.
The tractors are generally fitted with air
driers to prevent condensation in com-
pressed air. The tractors are generally
fitted with air driers to prevent condensa-
tion in compressed air. Even if the air
driers system, the humidity in the air can
be condensed. The condensed water
must be drained out via the drain valve.
The water in the air tanks should be
completely drained out. That's why
please push the valve on the air tanks.

2. Drain valve
The water in the compressed
air tank can cause corrosion
problems and affect the func-
tionality of the brake system.
The frozen water in the pneu-
matic lines can cause the fai-
lure of the brake system.
The water in the pneumatic
system should be checked
more frequently in cold weat-
her or extremely variable out-
side temperatures.
When the air tank pressure is
lower than 4,5 bars, the EBS
warning lamp on the tractor
turns on and the driver can
see this situation.
When the pressure in the ser-
vice line (in the red coupling)
is lower than 2,5 bars, the bra-
kes automatically lock.
3.1.3. EBS Socket
EBS Socket
Our trailers and semi-trailers are
equipped with an EBS system.
EBS is an electronically controlled brake
system, that is fitted with automatic load
sensing braking pressure regulation
(ALB) and automatic anti-skid systems
(ABS/ABV).
To activate the EBS system, your truck
and trailer must be equipped with an
EBS system. Please mount the EBS ca-
ble that will come from the truck to the
EBS socket on the trailer.

•Driving with a non-connected EBS
connection is illegal.
•Drive only with an approved and
well-operating EBS plug connection
in accordance with regulations.
•EBS connection must be made be-
tween the truck and trailer.
•When the EBS socket mounted and
truck engine is activated, you will
hear the noise. Please listen and
check carefully.
•A system control is performed two
seconds after the trailer EBS is
switched on; in the meantime, the
magnets may be opened and clo-
sed audibly for a short time. When
plugging the EBS connector, if you
cannot hear the system control, a
power supply problem exists be-
tween the tractor and EBS.
When the truck engine is activated and
during the travel, the EBS system will be
checked automatically. If the truck
screen is suitable/adjusted, the EBS fail-
ures will be shown with the EBS mistake
lamp.
The EBS mistake lamp on the truck
screen will be turned on when the igni-
tion key is activated. If there is no failure
on the EBS system, the lamp will be
turned off in appr. 2 seconds.
After 7 km/hours speed, If there is a fail-
ure on the EBS system (Sensor mistake
and etc.) EBS lamps will be flashed.
If the EBS lamp is activated, please con-
tact with authorized services
immediately.
The trailers equipped with a
Trailer EBS E braking system
may only be used with trac-
tors with:
ISO 7638-1996 connectors (ABS +
CAN) or ISO 7638, 7 pin with CAN data
line (EBS Truck)
If you drive without EBS con-
nectors or if there is a prob-
lem on the EBS system, the
brake system will not be wor-
ked properly. This situation
may cause an accident.
Trailers are equipped with an
additional power supply for
the EBS system. Thanks to
the extra power supply from
brake lamps, when the EBS
connector is damaged, an ex-
tra safety function will be acti-
vated. The EBS system will be
fed from brake lamps and ALB
(automatic load sensing bra-
king pressure) and ABV (anti-
skid system) functions will be
activated.
3.1.4. Rollover Stability Support (RSS)
Rollover stability support (RSS) is inte-
grated into the trailer modulator. The ve-
hicle’s electronic control unit analyzes
wheel speed, load information and trans-
verse acceleration data to detect the
likelihood of vehicle roll-over before the
driver realizes there is a risk and auto-
matically applies the brakes. But don’t
forget that this system cannot cancel the
laws of physics.
When the roll-over risk is detected, the
EBS system makes automatically brakes
and tries the reduce the roll-over risk.
After risk, the RSS function will be shut
down automatically.
The RSS optimizes driving
characteristics and in emer-
gencies may help to prevent
accidents. But cannot comple-
tely guarantee.
3.1.5. PREV (Park Release Emergency
Valve)
Generally, brake control systems will be
located on the driver's side. It may be dif-
ferent on your vehicle according to the
vehicle's construction.
