Touchscreen
The touch screen of the STREETEC autoleveling has numerous technical innovations that give the
system a very special value!
• The capacitive touchscreen works according to the same principle as a smartphone. Commands
are only made via touch without pressure.
• The system supports multi-touch mode. This allows different functions to be executed
simultaneously or in combination.
• A haptic feedback creates the impression of pressing real keys.
• Dimming when the driving lights are on increases safety when driving at night.
• Theuserinterfaceisindividuallycongurableforupto3differentusers.
The control panel (touch screen, Fig. 2) of the
STREETEC autoleveling consists of a
highquality aluminum housing with integrated
neodymium magnets.
With the help of the integrated magnets, the
control panel can be easily attached to all
magnetic parts in the vehicle.
The touchscreen has a USB-C port for
connecting to the harness.
Abb. 2: STREETEC autoleveling - Touchscreen
The USB-C port only works when the plug is inserted the right way round. If the
control unit indicates a communication error, the plug must be rotated! Optionally,
the control panel can be connected with the supplied angled USB-C plug. In this
case, the connection direction is irrelevant.

1. Decide in which direction you want to lead
the cable out of the valve block. By removing
the base plate (Fig. 4), the cable can be
positioned accordingly (Fig. 5) and xed in
place.
The STREETEC valve4 valve block (Fig. 3)
has been designed for clean installation and
maximum reliability.
The valve4 can ll and vent 4 compressed air
circuits and is equipped with G 1/4“ connections.
The valve4 is designed for maximum ow,
pressures up to 14 bar and millions of switching
cycles. Everything is integrated in one compact
unit. With an overall size of approx. 125 x
55 x 80 mm, the valve block is ideal for all air
suspensions.
The proven mounting of the valve4 valve block is installation inside the vehicle. If
installation outside the passenger compartment is desired, the installation location
should be selected so that the valve4 is protected from splash water and moisture.
Abb. 4: Base plate
Do not mount the valve4 overhead! Proper mounting of the valve block prevents
water from settling in frost-sensitive areas. In case of incorrect mounting, the proper
function of the STREETEC autoleveling cannot be guaranteed.

Water separator
The air generation kit compressors absorb moisture from the outside air. This moisture thus enters
the air tank, where it settles. The STREETEC autoleveling system is supplied with a water separator
that greatly reduces this moisture in the system and protects the system from corrosion and moisture
damage. This also reduces the risk of moisture entering the valve block to a minimum
Water separator
The tanks must nevertheless be drained regularly to eliminate the risk of residual
moistureinthesystem!Forthispurpose,pleaseinstallthetank‘sventvalvewith
a hose leading out of the vehicle interior to prevent moisture damage to other
components caused by the tank‘s venting. If this is not possible, place a highly
absorbentmaterial(e.g.microbercloth)undertheopeningofthedrainvalve.
Please observe the following installation guidelines:
1. Mountthewaterseparatorinthecorrectowdirection.The
arrowonthewaterseparatorindicatestheowdirection
and must point from the tank to the valve block (Fig. 7). If
youdecidenottomountthelterdirectlyonthetank,run
the required hose from the tank to the water separator and
the hose from the water separator with the appropriate
connectionsto the valve block.
Abb. 7: Flow direction
2. The water separator used in this system is a manually
vented water separator and must be emptied regularly.
This ensures that the drying always functions properly
and that no water enters the system. In this way, failures
of components, such as the valve block, can be avoided.
Use the venting button (Fig. 8) on the bottom of the water
separator for venting. When venting the water separator,
use a small container or a highly absorbent material (e.g.
microbercloth)tocollectthecondensationwater. Abb. 8: Venting head
3. Makesurethatthelterismountedinaverticalposition.Donotinstallthelterupsidedownorat
an angle (Fig. 9 - 12).

Pressure sensors Pressure sensors
The pressure sensors (Fig. 13) of STREETEC autoleveling
are extremely robust sensors for the automotive sector and
are designed for a pressure range from 0 to 16 bar. They have
a G1/4“ thread and are equipped with a seal so that they can
be installed without additional sealant. (Fig. 13)
5 pressure sensors are supplied with the STREETEC
autoleveling:
• 4 Sensors for the pressures in the air bellows
• 1 Sensor for tank pressure
We do not recommend mounting in the supply line and should only be done in
exceptional cases. The T-ttings for mounting would have to be purchased
separately in this case. (Part number: see component list page 68-69)
Abb. 14: Valve block Abb. 15: Sensor block
Abb. 13: Pressure sensors
The sensors for the air bellows can be integrated
into the system in various positions:
1. Mounting directly in the valve block (Fig. 14)
2. ounting in the optional pressure sensor block
(Fig. 15))
3. Mounting in the supply line to the air bellows
withoptionalT-ttings.
The sensor for the tank pressure can also be mounted in various ways:
1. Mounting directly in the side connection of
the valve block (Fig. 16)
2. Mounting directly to the air tank (Fig. 17) )
Abb. 16: Valve block Abb. 17: Air tank
When mounting the sensor on the tank, make sure that the pressure sensor is
installed in the upper area of the tank. Also make sure that the electrical connection
on the pressure sensor does not point downwards (Fig. 5). Otherwise, the sensor
may be damaged by condensation water settling in the tank.
3. hidden mounting on a hose leading away from the air tank or valve block.
Mounting on a hose leading away from the air tank or valve block is not
recommended and should only be done in exceptional cases.

Height sensors Height sensors
Height sensors (Fig. 18) should be installed with care. The
goal is to use as much sensor range as possible to achieve
maximum accuracy of height regulation. However, the sensors
must always be operated within the approved operating range
(Fig. 19).
Abb. 18: Height Sensors
Determine the mounting location of the height sensor:
1. Select a stable attachment point on the car body.
2. The sensor can be mounted in any direction as long as, in the center position of the sensor arm,
theattenedsideofthesensorshaftfacestheoppositesideoftheconnector.Theheightsensors
are shipped in position A (Fig. 20). Remove the sensor arm to rotate it to position B (Fig. 21)
or C (Fig. 22). If possible, mount the sensor in position A or B so that the arm is opposite or rotated
90 degrees from the port. If this is not possible, make sure that the connection cable cannot come
into contact with the sensor arm.
Ideally,mountthesensorsinthesameplaceonthedriver‘sandpassenger‘ssides
of the vehicle in mirror image. This ensures that the sensor area is as equal as
possible on each side.

vehicles, it will be necessary to fabricate a bracket to put the sensor and the coupling rod mounting
point in the correct position.
4. Makesurethatthesensorandthesensorarmhavesufcientdistancetochassisparts,thewheels
and other moving parts. It is important to ensure that this distance is maintained even when the
wheels are fully turned.
5. Furthermore,makesurethatthesensorsandthecableshavesufcientdistancefromhotvehicle
components.
6. Make sure that the attachment points are suitable for the entire travel of the trolley/vehicle.
7. Always try to use original mounting points and holes for mounting the sensor and coupling rod.
We expressly recommend performing the necessary work on a lifting platform and
with the aid of a gear jack. If a jack is used, it is to be expected that the work will be
signicantlymoredifcultandwillnotleadquicklytosuccess!

Selecting the sensor position
1. Attach the sensor to the vehicle and place the sensor arm
in the center position. Disconnect the air line from the air
bellows and raise the suspension to the lower end stop of
the chassis using a gear jack. Measure the distance [A]
from the sensor arm to the selected attachment point of
the coupling rod (Fig. 23). Make sure that the attachment
points are suitable for the entire travel distance of the
trolley/vehicle.
2. Reconnect the air line and apply enough air pressure
to the air bellows until the landing gear is at the upper
end stop. Now measure the distance [B] from the sensor
arm to the selected attachment point of the coupling rod
again (Fig. 24). The difference between the two measured
values gives the maximum travel [C].

Adjusting the length of the coupling rod
1. Using a gear jack, move the suspension to the center
position of the entire travel range and the sensor arm to
the center position of the working range. Now measure the
distance [D] between the selected mounting hole and the
mounting point of the coupling rod (Fig. 26).
Abb. 26: Sensor arm length
40 mm

Abb. 27: : Shortening the threaded rod
2. Shorten the threaded rod of the coupling rod. The length
of the threaded rod must be 40 mm less than the distance
measured in point 1 (Fig. 27).
3. Shorten the rubber cover on the threaded rod. The length
of the rubber cover must be 55 mm less than the distance
[D] measured in point 1 (Fig. 28).
4. If you do not have a tap available for deburring the
threaded rod, screw a nut onto the threaded rod before
cutting the rod. Use the nut to deburr the end of the rod
(Fig. 29)..
5. Screw the threaded rod into both heads of the couplingrod
about ten turns deep. This gives you an adjustmentrange
of about +/- 10 mm in length for any correctionsthat may
be necessary later. (Fig. 30)
6. Mount the coupling rod on the sensor arm and on
theattachment point on the suspension. Pay attention to
theangle between the coupling rod and the sensor arm
(Fig.31). This may be a maximum of 15 degrees and can
be corrected using spacers at the attachment point.

Height sensors
Checking the traverse path
1. After you have installed the sensors at all four wheel positions, you can check the
working area with the sensor tool in the control unit. Proceed carefully here so that
no damage occurs to the height sensors. Ideally, you should carry out the tests
in the rst step on the lifting platform and with the aid of the transmission jack.
The maximum voltage range of the sensors in the operating range is between 0.5 and 4.5 V.
These values must not be exceeded or undershot either when the chassis is completely raised or
completely lowered. Otherwise, the position of the sensors, the coupling rods or the length of the
coupling rods must be revised again.
