 MANUAL GUIDANCE INSTALLATION | CR7 | GENERIC

1 MANUAL GUIDANCE INSTALLATION

For installing a manual guidance only set connect the 3
pin COBO connector to a power outlet of the tractor.
Most of the time there is such a connector inside the
cabin (Figure 6). If this connector is not available inside
the cabin but there is another power supply the best
thing is to make a converter/adapter cable.

Connect this harness to the CR7, more information

about mounting the CR7 terminal is described in
Chapter 4.

This harness can be connected to one of the adapter

cables to connect an antenna. More information about
installing the antenna can be found in Chapter 3. FIGURE 6 POWER CONNECTOR MANUAL
GUIDANCE
When the customer wants to connect his CR7 with an
ISObus implement on an ISObus tractor the ISO-Incab
to CR7 cable can be used. Mount one side to the CR7
and the other side to the ISObus connection in the
tractor (Figure 7). The IBBC connector on the back of
the tractor can be used to connect the implement.

Please note!:
If you decide to hide the cables behind cover
plates be sure the cables will not get damaged.
Tie-wrap the wires so they are attached free
from vibration and friction.

2 STEERING SYSTEM INSTALLATION

This chapter describes the installation of all the
different steering systems, hydraulic, SmarTrax MD and
steer ready tractors. Look carefully at the system
overviews to know which parts of the installation are
applicable.

MOUNTING HARNESSES

When installing an autosteer system, the power cables

should always be connected to the battery. Two
options are possible, a Basic Harness (1-115-8000-141)
or a Implement Ready Harness (1-115-8000-060). The
differcence between these harnesses is the IBBC
connector, this one is included at a Implement Ready
(IR) Harness (Figure 8).

Power harness: an Implement Ready power harness is

mounted from the battery to the rear of the tractor. A
Basic power harness is mounted from the battery to
FIGURE 8 IBBC CONNECTOR
the chassis harness. Make sure that the relays and
fuses are mounted in a dry, clean and accessible spot
(Figure 9).

Which harness will be connected to the Power Harness

depends on which type of steering will be installed.
See system overviews on pages 6 - 10. All the
harnesses with a hard casing should be mounted
outside the cabin, all the harnesses with a braided
sleeve should be mounted inside the cabin. At all time,
find a good location where the cabling can enter the
cabin.

In addition, a number of guidelines have been

established for the assembly of all types of cable
harnesses: FIGURE 9 CORRECT MOUNTED RELAYS AND FUSES

 Mount the relays fixed and in a dry, clean and

accessible spot (Figure 9).
 The red wire is + (12V). The black wire is
(ground). Make sure that the first part of the
red wire (part in between battery and fuses)
cannot damage during operation.

PAGE 13/38 | Installation manual | 016-8000-014EN | Rev. A

 STEERING SYSTEM INSTALLATION | CR7 | GENERIC

 If necessary the positive and negative wires, in

between the battery and the fuses, can be
shortened. Be sure to use cable sockets with
the correct size for proper connection.
 If a ground switch is used, connect the wiring
harness behind the ground switch (not at the
battery side of the ground switch!).
 If a main (12V) switch is used in the red wire,
connect the wiring harness behind the main
switch (not at the battery side of the main
switch!).
 If no main switch is used, always connect the
wiring harness directly to the battery.
 If the system is connected to a 24 Volt
machine, always use a 24V to 12V converter.
Never connect between the two batteries of a
24V machine!
 Lead the terminal harness along with the GPS
and radio/GSM antenna cables through one
pillar of the cab.
 Tie-wrap the wires so they are attached free
from vibration and friction.

Caution!:
It is important to ensure that the wiring harness
is always connected to the battery AFTER
installing all wires and controllers!

ISO STEERING CONTROLLER

The following guidelines have been established for

mounting the ISO Steering Controller:

 Preferably, place the ISO Steering Controller

next to and to the right of the seat. Use the
standard ISO Steering Controller mounting
bracket.
 If it is not possible to attach the ISO Steering
Controller to the seat bolts, the ISO Steering
Controller should be attached in an
appropriate place in the cabin that is free from
vibrations.
 A ISO Steering Controller may only be
mounted in a horizontal position (with the
sticker side up). The connectors may be
orientated in four directions (0, 90, 180, 270
degrees).
 By default, the orientation of the ISO Steering
FIGURE 10 DYNAMIQ ISO MOUNTED NEXT TO THE
Controller is set to: horizontal position with

connectors pointing towards the rear (as
shown in Figure 10). Any other orientation
should be set in the software!

HYDRAULIC
2.3.1 HYDRAULIC VALVE

Figure 11 shows a manifold mounted onto a manifold

bracket with four M8 bolts. The manifold bracket is
preferably mounted at the right hand side of the
tractor (Figure 12). This is usually the side of the tractor
with the most space.

Please note!:
Make sure the connectors of the valves and the
pressure sensor can still be connected after
mounting the manifold. FIGURE 11 MANIFOLD BRACKET WITH A

 STEERING SYSTEM INSTALLATION | CR7 | GENERIC

2.3.2 HYDRAULIC INSTALLATION LOAD SENSE

The manifold should be connected between the hoses

leading from the steering orbitrol to the steering
cylinder(s). To do so, the hoses must be disconnected,
preferably on an existing connection between a pipe
line and a hose.

Connect the hoses from the steering orbitrol to A1

and B1 on the manifold. Connect the hoses to the
steering cylinders to A and B on the manifold (Figure
13 and Figure 14).

Connect the pressure line, return line and the LS line of

the hydraulic pump to the P, T and LS of the manifold.
When needed refer to the hydraulic drawing of the
tractor to find the correct connections on the tractor.
Steering Cylinder(s)
Caution!:
If there are separate hydraulic systems with FIGURE 13 LOAD SENSE CONNECTING CIRCUIT.
separate oil tanks on the tractor, the manifold
must be connected to the system in which the
steering orbitrol and steering cylinder are
included in.

Hint!:
Mark the lines twice with 'A' and 'B', before
disconnecting them.

Hint!:
Raven Europe can supplies hose kits for different
types of tractors. Please inquire about the
possibilities. FIGURE 14 CONNECTIONS FOR THE HYDRAULIC
LOAD SENSE MANIFOLD.

2.3.3 CONNECTING THE SHUTTLE VALVE

A shuttle valve should be installed in the load sense Signal from Signal from
other users manifold
line. See Figure 15 for proper mounting and
orientation of the shuttle valve. This way, when in rest,
the ball inside the shuttle valve floats inside the valve,
which will benefit the response for the load sense Signal to LS-
signal. In addition, it is important that the shuttle valve pump
is installed as close to the pump as possible.
FIGURE 15 TOP VIEW OF SHUTTLE VALVE FOR
MOUNTING IN THE LOAD SENSE LINE.

PAGE 17/38 | Installation manual | 016-8000-014EN | Rev. A

 STEERING SYSTEM INSTALLATION | CR7 | GENERIC

Hint!:
In case the wheels of the tractor are steering,
when the hydraulics of the tractor are operated;
a non-return valve should be mounted in the
load sense line from the manifold. The non-
return valve should let oil pass from the
manifold to the check valve/pump and should
block in opposite direction.

Hint!:
A shuttle valve for CNH tractors can be provided
by Raven Europe (order no. 13348001014) or

2.3.4 HYDRAULIC INSTALLATION OPEN CENTER

The manifold v3 open center consists of the standard

load sense manifold v3 with an add-on open center
part (Figure 16).

The pressure line that normally runs from the hydraulic

pump to the steering orbitrol, should be connected to
the P of the add-on open center part. Then connect a
line between P1 of the manifold and the pressure line
of the orbitrol. Connect the T of the manifold to a tank
inlet (Figure 17 and Figure 18).

Connect the hoses leading from the orbitrol to A1 and

B1 on the manifold. Connect the hoses to the steering

 STEERING SYSTEM INSTALLATION | CR7 | GENERIC

2.3.5 PRESSURE RELIEF VALVE

A pressure relief valve is mounted to the add-on part

of the open center manifold (Figure 19). This pressure
relief valve must be set to the maximum allowable
control pressure of the steering system. The default
setting of the pressure relief valve is about 180 bar.
Determine the maximum pressure of the steering
system before mounting the manifold. Follow the next
steps:

 Mount a pressure gauge in the pressure

line between the hydraulic pump and the
steering orbitrol.
FIGURE 19 OPEN CENTER MANIFOLD.
 Steer the front wheels to one side and
keep steering until the maximum pressure
is reached.
 Read out the value on the pressure gauge.

After mounting the manifold. Set the maximum

pressure of the pressure relief valve, equal to the
maximum pressure of the steering system. Follow the
next steps:

 Mount a pressure gauge in the pressure line

between the hydraulic pump and the manifold.
 Loosen the locking nut of the pressure relief
valve.
 Loosen the pressure relief valve two turns
counter clockwise.
 Steer the front wheels to one side, using the
Left/Right buttons of the CR7. Keep steering
until the maximum pressure is reached.
 Read out the value on the pressure gauge.
 Adjust the pressure relief valve until the
pressure is equal to the pressure it was before
mounting the manifold.
 Secure the pressure relief valve with the
locking nut.

2.3.7 MOUNTING AND CONNECTING THE

STEERING CONTROLLER

The steering controller bracket can be mounted to the

manifold. The steering controller can then be fitted to
the manifold bracket (Figure 21).

Important notes when mounting the controller:

 Mount the steering controller with connectors

directed downwards to prevent the ingress of
water.
 Do not mount the steering controller too close
to parts which have a high temperature (for
example, the exhaust system of the tractor).

Connect the DIN connectors marked "Left" and “Right”

to the proportional valve. Connect the DIN connector
marked "Lock" to the shut-off valve. Connect the 4-pin
Phoenix M12 connector to the pressure sensor of the
FIGURE 21 SIDE VIEW OF THE STEERING
manifold.
CONTROLLER FITTED TO THE MANIFOLD.

Please note!:
The torque of the pressure sensor in the
manifold V3 is 30 Nm. It is not necessary to
check this at delivery of a assembled manifold.
However, make sure, when replacing the
pressure sensor, that it is tightened with the
correct torque.

2.3.8 STEERING ANGLE SENSOR

For a correct operation of the Raven system a wheel

angle sensor is necessary. In various types of tractors a
factory fitted wheel angle sensor is already mounted in
the front axle. For different tractor types a ‘spy cable’ is
available at Raven to use the factory fitted wheel angle
sensor for the Raven system. When a spy cable is used
it is not necessary to install a Raven wheel angle
sensor. Ask Raven for more information about the
availability for a specific tractor brand or type.

2.3.9 MOUNTING SPY-CABLE

Take the following steps to mount a wheel angle

sensor spy-cable:

1. Follow the cable from the wheel angle sensor

on the front axle pf the tractor to the first
connection in this cable.
2. Disconnect the connectors.
3. Connect the spy-cable in between the
connectors.
4. Connect the wheel angle sensor 5M cable to
the M12 connector of the spy-cable.
5. Mount the spy-cable in a clean and dry
position (Figure 22).

2.3.10 MOUNTING THE WHEEL ANGLE SENSOR

Figure 23 and Figure 24 show a detailed view of the

structure of a wheel angle sensor assembly. Table 1
also lists the components shown in Figure 23.

1. If the front wheels are straight, the screws of

the sensor housing and sensor disc should be
aligned with the front axle. It is also important
that the sensor disc is rotated in such a way
that the triangles in the disc and the sensor

voltage reading.

2. The sensor housing and sensor disc should be

aligned EXACTLY on the pivot point of the stub
axle. The centre-to-centre distance of the
mounting holes is 28 mm.

Please note!:
At all times the triangles on the sensor housing
and sensor disc must be pointing in the same

 STEERING SYSTEM INSTALLATION | CR7 | GENERIC

1. If there is a grease nipple at the bottom of the

stub axle (stub axle with triangle), then a
special U-shaped bracket is to be used for the
wheel angle sensor housing (Figure 27 and
Figure 26).

2. It is recommended to assemble the sensor

housing on the bottom side of the axle stub.
Install the sensor housing with the wire
pointing backwards.
FIGURE 25 TRIANGULAR MARKINGS ON THE 12V
WHEEL SENSOR.
Caution!:
Sensor housing should always be mounted
above the disk to prevent the accumulation of
dirt.

3. Mount the sensor housing with the M5X16

bolts (allen bolt, countersunk head).
Countersink the drill holes in the wheel angle
sensor mounting bracket beforehand, so the
heads of the M5 bolts are fully countersunk in
the mounting bracket when tightened (Figure
24). To prevent damage to the inside of the the
sensor housing, make sure the M5 bolts are
not too long.
FIGURE 27 STEERING ANGLE SENSOR ON NEW
HOLLAND.
4. The connecting cable can be provided with a
protective sleeve for longer life. Feed the cable
via the stub axle and direct it over the top
(stub axle/pivot point) of the front axle so that
the wire is not pinched or constricted.

2.3.11 MOUNTING THE SENSOR DISC

1. Mount the sensor disc without spacers on the

provided 20x3 strip (Figure 28).

2. Mount the sensor disc in the sensor housing

and mark where the first bend should be made
(about 10 cm from the beginning). The first
bend should be as close as possible to the
sensor disc and be positioned as tight as
possible against the stub axle housing to
prevent damage by crops or soil (Figure 28 and
Figure 29). The most extreme wheel position is
usually the tightest position of the strip. Do not
bend the strip too sharply.

3. Mark the position of the second bend in the

strip until the sensor disc fits nice and flat in
the sensor housing. On the other side, the strip
must rest just underneath and against the front FIGURE 28 DISC ON THE STRIP WITHOUT SPACERS.
axle. The strip should rest on the sensor
housing. Cut the strip to the correct length.

4. The wheel angle sensor strip should now be

mounted to the bottom of the front axle
(Figure 29). Mark the location of the holes on
the strip and drill two 5 mm holes in the strip
at approximately 30 mm apart.

5. Hold the strip with disc in the correct position

and drill the first hole in the front axle with a 5
mm drill bit (about 10-15 mm deep). Drill into
the thickest part of the front axle. Not too
deep! FIGURE 29 STRIP WITH SECOND BEND AND
SHORTENED.
Caution!:
Ensure that the hole does not wear out when
drilling (drill clean and straight). When drilling,
ensure that the strip is under tension when
positioned against the sensor housing to prevent
the strip from vibrating.

 STEERING SYSTEM INSTALLATION | CR7 | GENERIC

6. Tap the first thread in the hole drilled into the

front axle using a M6 screw-thread tapping
attachment. Now fasten the strip with one M6
bolt (Figure 30).

7. Drill the second hole in the front axle with a 5

mm drill bit. Remove the strip again and tap
the second screw thread in the hole in the
front axle.

8. Drill the second hole in the wheel angle sensor

strip with 6 mm drill bit. Fasten the strip with
two M6 bolts.
FIGURE 30 STRIP ON THE FRONT AXLE WITH ONE
BOLT.
9. Make sure the sensor disc falls nice and flat
into the sensor housing and the strip also lies
flat and under tension on both sides of the disc
positioned against the sensor housing. Press
with your thumb against the end of the strip
and check if the strip bounces back easily
without friction (Figure 36 and Figure 37). The
sensor disc may only have a little bit of friction
in the sensor housing.

10. If necessary, bend the strip a little bit. Two

Bahco’s are useful tools to do this (Figure 31).

11. Remove the strip again and mount the sensor

disc on the bottom of the strip (Figure 32).
FIGURE 31 BEND THE STRIP WITH THE HELP OF

front axle.

13. Check if the sensor disc is properly centered

with the sensor housing. The strip has to lie flat
under slight pretention against the sensor
housing (Figure 32). Also turn the wheels to
make sure the sensor housing remains properly
centered in various wheel positions.

FIGURE 32 DISC AT THE OTHER SIDE OF THE STRIP.

14. Remove the strip again from the front axle.

Then mount the strip again to the front axle
with the aid of M5 X 30 bolts, raised with two
nuts and two washers on each side. Mount on
the correct side of the strip (Figure 33) and pay
attention to the orientation of the disc (Figure
25). The triangular marker must be on the
correct side.

15. Make sure the sensor magnet (Figure 34) in the

sensor disc is completely clean (no iron fillings)
before being mounted. Clean the sensor
magnet with compressed air if necessary FIGURE 33 WHEEL ANGLE SENSOR DISC MOUNTED
(Figure 35). Mount the strip back on the front WITH SPACERS.
axle.

16. Check again if the sensor disc lies under slight

pretention against the sensor housing (Figure
36). Push with your thumb to the end of the
wheel angle sensor strip to check this. The
sensor disc may only have a little bit of friction
in the sensor housing. The sensor disc should
bounce back easily and without friction (Figure
37).

Caution!:
The sensor disc should be in a fully centered FIGURE 34 DIRTY WHEEL ANGLE SENSOR MAGNET.
position within the sensor housing. The strip
should be able to flex in a downward direction.

 STEERING SYSTEM INSTALLATION | CR7 | GENERIC

Hint!:
It is often useful to drill bigger holes (slots) in
the wheel angle sensor strip for the sensor disc.
Allow the nuts to be loose-fit when mounting
the strip. The disc then centers itself
automatically. Do not forget to tighten the nuts
again.

Caution!:
Make sure the magnet of the wheel angle sensor
is completely clean (no iron fillings) before
mounting it. Cleaning the wheel angle sensor
magnet with compressed air can prevent
problems.

2.3.12 HEAVY-DUTY CARRARO FRONT AXLE WITH

INDEPENDENT SUSPENSION

Tractors with the heaviest type of Carraro front axle

with independent suspension must be fitted with a
special wheel angle sensor bracket (Figure 38). This
type of assembly requires a wheel angle sensor with a
much wider range (180°) in connection with the larger
wheel turn (blue coloured wheel angle sensor). The
wheel angle sensor should be mounted at the right
sight behind the front axle of the tractor (Figure 38).

Required parts:

 180° wheel angle sensor FIGURE 38 CARRARO FRONT AXLE.

 Wheel angle sensor bracket
 M8 threaded stub with nuts
 2x M8 ball joint
 Carraro front axle wheel angle sensor bracket
 Carraro front axle tie rod bracket

Method of mounting:

 Install the wheel angle sensor to the bracket.

 Mount the bracket to the front axle.
 Set the arm of the sensor approximately 20
degrees off center (Figure 39). This means that
the ball and socket joint of the wheel angle
sensor are flush with the ball joint of the
control rod. This in order to prevent, when fully
to the left, the arm of the sensor and the
threaded rod with the ball joints scissors with FIGURE 39 SENSOR WITH BRACKETS.
each other.
 Cut the threaded rod to measure. The ball
joints are center to center 180mm long. Fit the
clamp to the tie rod and the threaded rod with
ball joints.
 After mounting check the mechanism by
steering fully left and right.

STEER READY TRACTORS

Most of the tractor brands which are already equipped

with a factory fitted GPS ready system can be
contolled with a steering system of Raven in
combination with a CR7. Examples are Fendt
VarioGuide, John Deere AutoTrac Ready, New Holland
Intellisteer. Look at the actual price list to see which
tractors can be controlled with a Raven CR7.

You can find the installation manuals of these tractors

on our website.

 GPS RECEIVER INSTALLATION | CR7 | GENERIC

3 GPS RECEIVER INSTALLATION

Two types of GPS antennas are available for the CR7.
The 500S and 600S.

INSTALLATION 500S & 600S

For connecting a 500S antenna use this adapter cable:

1-115-8000-342. For connecting a 600S use this
adapter cable: 1-115-8000-345. Look at the correct FIGURE 42 MOUNTING PLATE 500S

system overview of the CR7 to know which cable

should be connected with the adapter cable. If the
antenna is not connected make sure that the
connectors on the roof are provided with a protective
cap (Figure 46). With this protective cap no dust and
water can enter the connector.

For both antennas a mounting plate is available. FIGURE 43 500S ANTENNA

(Figure 42 & Figure 44)

Furthermore, the following guidelines must be

observed when installing the GPS antenna:

 Mount the GPS-antenna with the connectors

pointing to the backside.
 Mount the GPS-antenna in front of the rear
axle.

Hint!:
When the customer disconnects his antenna the FIGURE 44 600S ANTENNA ON MOUNTING PLATE

best he can do is to disconnect the adapter cable

from the GPS to roof connector. If the antenna is
removed from the tractor, the adapter cable
should stay with the antenna.

4 CR7 INSTALLATION

MOUNTING THE TERMINAL

The following guidelines have been established for

mounting the terminal (Figure 47):
 Always contact the customer about the
terminal position in the cabin.
 Always use a RAM-C ball attachment. (Figure FIGURE 47 CR7 ON A-PILLAR
48 & Figure 49)
 Mount the terminal free of vibrations with a
solid bracket. A variety of mounting brackets
are available for this purpose.
 Secure all cables in the cabin.
 Mount in such a way that the display is
directed straight towards the driver.
 Mount in such a way that driver has a clear
view all around.

Hint!:
Mount the terminal in such a way that it
does not obstruct the view of the driver over
the top of the right-hand fender, but also so
FIGURE 48 RAM-C BALL ATTACHEMENT
that the inside of the front wheel on the
ground is still clearly visible.

SLINGSHOT INSTALLATION

If a SlingShot modem is used, in addition to the GPS-

antenna, two GPRS / UMTS antennas and a GPS patch
should be mounted.

least 100 cm of each other (like the CNH antenna-
bracket in Figure 51). If a standard GPS-antenna
bracket is mounted, one of the GPRS / UMTS-antennas
should be mounted on this bracket (Figure 50). The
second GPRS / UMTS-antenna should be mounted on
a metal bracket on the cabin (Figure 52).

It is important that the following conditions are met at

all times:

 The GPRS/UMTS antenna is equipped with a FIGURE 51 CASE NEW HOLLAND WITH GPS-
magnetic base and must be placed on top of ANTENNA, GPS PATCH ANTENNA AND TWO
GPRS/UMTS ANTENNA’S.
the cabin.
 The antenna should have a clear reception all
round.
 Label the antenna cables inside the cabin with
labels ‘Cellular’ and ‘Diversity’ (Figure 53).
 Mount a grey SMA grip on both connectors
(Figure 53).

When using a SlingShot modem also a GPS Patch

antenna should be mounted (Figure 52). The GPS
Patch antenna is magnetic. Mount the GPS Patch FIGURE 52 GPRS/UMTS-ANTENNA AND GPS
antenna always on the roof of the cabin. Be careful PATCH ANTENNA ON A METAL BRACKET.
with mounting the GPS patch antenna; the GPS patch
antenna cable is quite thin and fragile. Label the GPS
Patch antenna cable inside the cabin with label ‘GPS’
and mount a blue SMA grip to the connector (Figure
53).

Connect the power cable to the connector with label

‘’Slingshot PWR’’ and connect the RTK IN/GPS OUT
connectors with each other. Connect the Serial RTK IN
with the Slingshot and connect the Ethernet cable
between the SlingShot and the CR7.
