Foreword
This guide is intended for drivers and/or other EF-S system users and contains the
necessary TRIDEC information regarding the use of the EF-S system. This User manual
must always be stored in the vehicle.
A separate maintenance and repair manual for service technicians is available on the web-
site: www.tridec.com .
Separate installation instructions for the system are supplied upon delivery of the EF-S sys-
tem.
Effective use:
The EF-S system system is not designed to be used independently. It has been designed to
be mounted as an external steering system to a trailer/semi-trailer. Any modifications what-
soever could compromise the safety of the system. Both the TRIDEC product guarantee and
the homologation shall be rendered invalid if these products are modified without written
consent from TRIDEC. All guarantee claims against TRIDEC or suppliers of the EF-S system
shall be declared invalid if the EF-S system is not installed according to the instructions sup-
plied by TRIDEC.
Prior to putting the system into service, compliance with the applicable national road traffic
regulations must be established for the trailer on which the system is installed. The system
may only be used in accordance with the manual for the truck and any other trailer manuals.
The diagrams in this manual are only included as examples and are not intended for any
other purposes. Images shown may vary slightly from the system supplied.

onment" on page69).Safetyrisksaredepictedusingpictogramsin

1 Description
The following paragraphs contain information about the components that make up the EF-S
system and how the system works.
1.1 Operation
The EF-S system is a total system developed by TRIDEC. Its purpose it to steer trailers/semi-
trailers with one or more steered axles.
It allows the driverto alter the steering angle of the wheels on the steered axles when man-
oeuvring a trailer/semi-trailer, which makes manoeuvring easier. Once the manoeuvring has
been completed, the wheels can be turned back to the driving direction, either manually or
automatically.
The EF-S system allows the driver to steer the trailer/semi-trailer either manually or auto-
matically. When the “Automatic” function is active, the EF-S system only steers according to
the Ackermann principle (see Figure 1-1).
Figure 1-1
With the Ackermann principle, each steered wheel draws a circle. The middle points of
these circles are all in the same place.
The wheels of the trailer turn depending on the angle (0WS) (see "System info" on page74)
between the tractor unit and the trailer/semi-trailer. These angular rotations are determ-
ined in advance and are set per axle in the EF-S system’s program. The EF-S system has a
centring circuit and a number of steering circuits (dependent on the order).
Part no.: 162014 EN-1 3Release 07/2020
User manual 2300 EF-S system

During automatic steering, the angular rotation of the wheels of the trailer/semi-trailer is
100% up to a vehicle speed of 30 km/h(see Figure 1-2). That means that the steering angles of
the trailer’s wheels are exactly the same as the pre-set angular rotations. The angular rota-
tions reduce at a speed of 30-50 km/h. They are, therefore, smaller than the pre-set angles.
At speeds above 50 km/h, the wheels of the trailer/semi-trailer are no longer steered when
the tractor unit changes direction. The centring function automatically becomes active at a
speed of more than 65 km/h.

Figure 1-2
The EF-S system uses two EBS signals:
nThe speed signal
nThe on/off signal
To determine the speed of the articulated vehicle, the EF-S system uses the speed signal.
The on/off signal is used to start the battery-charging main control unit when EBS becomes
active.

Manually, the wheels can be steered according to both the Ackermann principle and the crab
steering principle (see Figure 1-3).

User manual 2300 EF-S system

1.3 Battery charger
The batteries for the EF-S system are charged by the generator via the NATO connection
with a charging current of no more than 45 A when the tractor unit’s engine is running.
Figure 1-6
The intelligent charger measures the temperature of the batteries. This makes it possible to
adjust both the charging current’s amperage and charging voltage to the temperature. At a
low battery temperature, a higher amperage and voltage are required to keep the battery at
the desired voltage. At a higher temperature, the amperage and the voltage can be lower.
The charger can provide a maximum current of 45 A. The charger is protected by two fuses.
The input has an automatic fuse, while the output has a 60 A replaceable fuse. The charger is
sealed. The fuse may only be replaced after permission has been granted by TRIDEC.

1.4 Warning light
The EF-S system has a warning light. This light has three colour areas:
nRed
nOrange
nWhite
Each colour area has a separate function and can light up.
Figure 1-7
The white warning light indicates that the EF-S system does not have any faults and is ready
for use. When the system pressure is reached, a message will appear on the display.
By pressing you activate the steering system and the signal light will go out.
The orange light indicates a system error or that the system is not yet ready for use. It is still
permitted to drive the trailer/semi-trailer. If the red warning light is lit, it is NOT permitted
to drive the trailer/semi-trailer. Contact the service workshop for further instructions. The
warning light must be located in a position where it can easily be seen from the tractor unit’s
cabin.

User manual 2300 EF-S system

The following accessories are available for the remote control:
nA synchronisation cable to synchronise the remote control with a computer.
nA holde, also charger.
nA charging cable. This cable can be used to connect the remote control to a 12 V or
24 V socket.
nA belt.
The remote control is automatically activated when it is connected (see Figure 2-2) to the tractor
unit’s cigarette lighter and when the ignition key is rotated to the accessory position or fur-
ther.

2.2 Replacing the batteries
When the batteries have reached the end of their service life, the following message is dis-
played at the bottom of the screen while charging.
Figure 2-4
nThe batteries may only be replaced with rechargeable NiMH (Nickel Metal Hydride)
AA-size batteries with a recommended capacity of 2000 mAh.
nThe batteries must be removed if the remote control is not going to be used for an
extended period of time (longer than one month).
nDo not place fully discharged batteries in the remote control. The system does not
have sufficient capacity to charge them.
nRemove the batteries from the remote control when they are fully discharged and
recharge them in a charging station.
