H2 SYSTEM OVERVIEW AND ASSEMBLY
§2.1 SYSTEM OVERVIEW
The System Flowmate Control FMC comprises the following components (see fig.):
•Control box
•Distribution box
•SHC box (section-hydraulic-control)
The control box is assembled in the tractor cabin and contains the spraying computer and the
remote control for the control of the spraying and hydraulic functions.
The transmission of the control commands is done according to the new CAN bus protocol (ISO
11783) via the control wire and the distribution box to the SHC box on the sprayer (see fig.).
Pressure regulator, Section valves and solenoid valves are actuated, the signals of the sensors
such as wheel sensor, flow meter etc. are detected and transmitted to the computer in the control
box via the SHC box.
The supply of current is via the current supply wire and the distribution box on the sprayer.
From the distribution box, the control box in the tractor and the SHC box are supplied with current.

§2.2 ASSEMBLY
Assemble the control box (fig. 1) in the tractor cabin with the enclosed assembly material (fig. 2).
Ensure that a position favourable for operation in the driver's field of vision is selected.
The control wire for the spraying system is inserted in the left-hand socket (1) on the reverse of the
control box and secured by means of a screw-type connection (fig. 1).
If the speed measurement is done via the tractor, the wire of the speed sensor or the adapter cable
to take over the speed signal from the tractor's electronics is inserted in the right-hand socket (2)
and screwed tight.
If the speed measurement is done via a sensor on the wheel of the sprayer (trailer sprayer), the
sensor cable is connected on the SHC box of the sprayer.
The control box is switched on via the switches (3) on the reverse (fig. 1).
§2.2.1 Supply of energy
In newer types of tractor which are equipped with an energy supply socket to DIN 9680, the energy
supply wire of the Flowmate Control, which leads to the distribution box on the sprayer, can be
inserted directly on the DIN socket of the tractor (see system overview).
In older tractors not equipped with a DIN socket, the battery wire (4) (fig. 3) is necessary and must
be connected directly to the battery. The battery wire is not standard and must be ordered
separately.
Use of the battery wire, which is fused with a 30 A fuse, ensures that the Flowmate Control is
always sufficiently supplied with energy.
When connecting to the battery, pay attention to correct poling!
The brown core with the integrated 30 A fuse must be connected to the +pole, the blue core to the
-pole. Please ensure clean contacts!
By no means can the supply of energy be produced via the so-called cigarette
lighter, as it cannot provide the current required!
The other side of the wire is equipped with a standard socket, which must be attached in a dry,
protected area in the rear of the tractor or the tractor cabin. The energy supply wire of the
Flowmate Control, which leads to the distribution box on the sprayer, is inserted in this socket.
Before connecting the Flowmate Control to the 12 Volt electrics, the following checks must be
made:
-Check electric components and wires for possible damage. Damaged wires are no longer
waterproof and can cause short circuits.
-Check the wire length; it must also be sufficient for taking bends.
-Check correct connection of the plug to the control box.
-Naturally, the 12 Volt battery must also be sufficiently charged (9 Volts at least).
Note: Please ensure that the two wires (energy supply and control wire) are laid carefully
between the tractor and the sprayer in work so that nobody can trip up and the wire does
not get caught anywhere.
However, the wire must not be tied up too tightly, because otherwise it can tear in bends
or in lifting or lowering.
Further, please ensure that the wires cannot come into contact with moving or hot parts
of the tractor.

If live parts or wires are damaged, short circuits can result. Therefore, the energy
supply wire must always be equipped with a 30 A fuse. Without properly fusing, a
fire can be caused by a short-circuit!
§2.2.2 Assembling the speed sensor
If a sensor with a counting ring is selected for the speed measurement, it should be attached to a
non-driven wheel as far as possible. If an added appliance is used, the parts are fitted to the inside
of the front right wheel of the tractor.
If a trailer with a spray computer is ordered, the speed sensor with the counting ring is assembled
in the factory. In this case, the system merely needs to be calibrated (see paragraph Ҥ5.10 on
page 41).
Proceed as follows when assembling the counting ring:
•To start with, the wheel (5) to which the counting ring (6) is to be fitted is dismantled (fig. 4).
•Push the drilling template (7) over the four long screws of the counting ring (6) and align the ring
centrically to the edge of the rim, to the hub opening and to other circular shapes of the wheel
with the help of the circles on the drilling template. This can be done both on the outside and
also on the inside of the wheel (fig. 4).
•Then the bores (8) are marked, centred and drilled with a 10.5 mm drill (fig. 4).
•Screw the ring on the inside of the wheel and attach the spacers (9) between the ring and the
rim. Check whether the ring has been aligned precisely parallel to the rim (fig. 5).
N.B.: Longer spacers are needed for trailed sprayers.
•After this, fit the wheel back onto the tractor or sprayer.
Note: In most four-wheel driven tractors, the speed sensor can often be fitted to the cardan shaft
without problems by means of a self-made holder. The sensor can react to protruding
metal parts on this shaft (hose clamps or welded-on nuts). The counting ring then does
not need to be dismantled!

Assembling the sensor
•The speed sensor (10) must be fitted in such a way that it is as close as possible to the counting
ring (6). Trailer sprayers have their own holder on the axle of the sprayer for this purpose. If an
add-on sprayer is used, the holder for the speed sensor must be fitted in the outer area of the
front tractor axle in such a way that it also turns in steering (fig. 6)
As a matter of principle, please ensure that the sensor is not put at risk by plants on the field
and other objects.
•If no suitable screw or clamp-type fitting is available, the centring bores of the wheel axle or the
king-pin must be drilled open and a thread cut into the bore. Please ensure that the sensor must
transmit at least 50 impulses over a distance of 20 metres.
Note: The clamp (11) must be fitted with at least two screws in order to prevent the sensor from
vibrating or being pushed away from the counting ring.
THE SENSOR MUST NOT TOUCH THE COUNTING RING UNDER ANY
CIRCUMSTANCES!
•The supplied bar (12) can be used for the assembly of the sensor in the area of the front wheel
of the tractor (fig. 7).
•Assemble the sensor in the clamp holder and rectify any possible inclination of the counting ring
with the shims (13) (fig. 8).
•Move the sensor in the clamp holder (11) in such a way that the distance from the counting ring
is 3 to 6 mm (fig. 7 and 9).
•The speed sensor (10) must be arranged on the cams in such a way that the middle of the
sensor is opposite the inside edge (14) of the cams (fig. 9).
Note: If the sensor is fitted too far towards the outer edge of the counting ring, it does not
recognise the individual cams. In this case, no impulses are transmitted and the system
does not count.
•Check whether the sensor counts each cam, the control lamp on the sensor must light up each
time. This is checked by lifting the axle of the tractor or the EMPTY field sprayer with a jack and
turning the wheel by hand.
When lifting the wheel, always operate the parking brake of the tractor first and secure
the vehicle against rolling away with wedges to be on the safe side!
Calibration of the speed sensor is described in paragraph Ҥ5.10 on page 41.
•Lay the sensor wire to the driver's cabin and connect the plug to the control box (fig. 1).
Note: When laying the sensor wire, please also consider the maximum steering angle!

H3 CONTROL BOX
The control box of the Flowmate Control FMC (fig. 1) contains an electrical remote control for the
spraying functions and the hydraulic functions (spray boom and drawbar) and the actual spraying
computer.
§3.1 SPRAYING FUNCTIONS
The following spraying functions can be electrically remote controlled on the control box (fig. 1):
Central switch “Spraying” On/Off (1)
When the central switch is operated (1) all the Section valves (7) (fig. 2) are opened or
closed at the same time (Switch upwards = valves are open).
Section switch (2)
When the Section switch is operated, (2) the Section valves (7) (fig. 2) are opened or
closed (Switch upwards = valve is open).
Switch for edge nozzles or Sections (3)
The two outside switches (3) can be used to switch edge nozzles. There are 2 possibilities
for this:
a) Edge nozzle for precise edge-of-field spraying:
In this case, there is a switch-over between the outermost nozzle and the edge
nozzle (with a smaller spraying angle to the outside).
The working width is not altered.
b) Edge nozzle to enlarge the working width at the edge of the field:
In this case, the edge nozzle (with a larger spraying angle to the outside) is used
additionally in order to enlarge the spraying width at the edge of the field.
Note: The kind of use of the two outside switches (3) must be pre-selected in the "Setting
menu” (screen 16) of the spraying computer.
Switch for pressure adjustment +/- (4)
When the switch is operated (4), the spraying computer automatically switches from
Automatic to Manual mode. At the same time, the pressure regulation motor (8) (fig. 2) is
actuated in the direction in question (+or -) as long as the switch (4) is held down. The
spraying pressure (bar) can thus be altered manually. The actual spraying pressure can be
read of the manometer on the machine
Attention: The desired spraying pressure has to be set while spraying (central switch
spraying "On")
Switch for return agitator (5)
Motor (9) (fig. 2) for the agitator switch-off is actuated via switch (5). The return agitator can
be switched off as required, e.g. for complete emptying of the container or also for foaming
pesticides.
Note: The fact that the agitator has been switched on can be seen by a rotating beam (6)
in the top left of the display (main menu, screen 1) (fig. 1).

§3.2 HYDRAULIC FUNCTIONS
The lower field (10) of the control box contains the switches for the hydraulic functions of the spray
boom and the drawbar - or axle steering (fig. 3).
Depending on the kind of hydraulic system on the spraying unit, there are 2 different control boxs,
which can only be distinguished externally by the switches for the hydraulic functions.
- In the version with pre-selection switching, toggle switches with 2 switching positions are fitted.
- In the version with electro-hydraulic controls (oil circulation system) keys with a middle position
have been installed.
§3.2.1 Hydraulic system with pre-selection switching
- On the tractor side, 1 single-acting and 1 double-acting hydraulic ventil is necessary.
- With the single-acting hydraulic ventil the height adjustment of the spray boom is performed.
- All the double-acting hydraulic functions are pre-selected via the corresponding toggle switch
on the control box (fig. 3) and implemented via a double-acting hydraulic ventil on the tractor.
- The direction of operation of the hydraulic ventil decides on the direction of operation of the
function implemented.
Note: The height adjustment of some types of field-sprayers is done directly via a single-acting
hydraulic ventil on the tractor. In that case, toggle switch for height adjustment on the
control unit is without function (see also instruction manual of the spray boom).
Procedure for control:
•To operate a function, push the corresponding toggle switch upwards, the corresponding
solenoid valve (11) on the spray boom is opened (fig. 4).
Attention:In order to avoid damage to the spray boom, only activate one function at a time,
i.e. the remaining toggle switches must be pushed down. In symmetrical functions
such as folding, both sides (right and left) can be activated at the same time as a
rule.
•To implement the function, operate the double-acting control device in the corresponding
direction until the function has been completely implemented.
•After this, push the toggle switch down again.
§3.2.2 Hydraulic system with electro-hydraulic control (oil circulation system)
- On the tractor side, only 1 single-action hydraulic ventil and a pressure-free return line are
necessary.
- The hydraulic ventil of the tractor is to be set in such a way that it is permanently supplied with
pressure.
- All the hydraulic functions can be operated directly via the switches on the control box.
- The direction of operation of the switch in question decides on the direction of operation of the
function implemented.
