Figure 1. Correct PTO geometry.
If the machine is milling with the tractor at an angle to the
machine on a regular basis it is recommended that a PTO
shaft with a wide angle, constant velocity joint be fitted.
9.2 Connecting the hydraulic supply
Connect the hydraulic supply and return hoses for the
conveyor rams into the spool valve connections of the
tractor.
9.3 Connecting The Control & Junction Box.
Place the control desk in the cab and attach it in a
convenient location using the suction cup. Plug the control
desk into the power supply.
Route the machine cable to the tractor auxiliary power
socket ensuring it is kept away from the rear wheel and
any pinch points between the PTO shaft and link arms.
Where possible, route into the cab through cable entry
points on the tractor, allowing the rear window to be kept
closed during use.
Ensure the functions of the control desk are completely
understood before proceeding to use the machine. In
particular the bale chamber is actuated in the forward
direction by pushing the milling direction button and
stopped by pressing the button again. Reverse of the bale
chamber can only be actuated by holding the reverse
button.
The control desk will not turn on until the Bluetooth
connection with the machine has been established, the
LED stops flashing and is illuminated. To establish this
connection both the control desk and junction box must
be connected to a power source.
Should the control desk fail to connect to the machine,
then press the “ON” and “OFF” buttons together for 2
seconds. This will make the control desk search for the
Bluetooth signal from the Tomahawk.
Note: Make sure
the ‘power on’ is illuminated to run the conveyor. Make
sure the conveyor is straight & lowered before running.
9.4 Programming Electronic Controls
Before adjusting the settings for the rotational
speed of the bale chamber it will be necessary to
unfold the conveyor and lower it to a working
position.
The electronic controls are programmable via the control
desk to optimise the performance of the machine.
The following instructions will allow you to programme
the stop position (0) and high speed position (10) of the
bale chamber speed dial. This process will allow
maximum bale chamber rotation speed without
compromising the other services the valve block can
provide.
Figure 2. Control desk.
To perform this operation the following steps must be
followed exactly.
a)
Turn on the tractor and engage PTO shaft drive
which will start the hydraulic system.
b)
Set the tractor engine revs to a achieve a 1000
rpm PTO speed.
c)
With the control desk off, turn the bale chamber
rotation speed dial down to 0.5.
d)
The following buttons must then be pressed &
held down in this order;
1 Bale chamber milling direction.
2 Automatic bale chamber speed
control.
3 On.
e)
Hold the sequence of buttons for 8 seconds until
both the ‘bale chamber milling direction’ and ‘on’
LED’s illuminate.
f)
Release buttons and the LED’s should flash
alternately.
g)
Using the automatic bale chamber speed
control button to slow down,
and the manual bale chamber speed control
button to speed up,
h)
slow the bale chamber down to the point where it
just stops.
i)
Press the ‘off’ button to save the slow speed.
You have now programmed the electronic controls for
the minimum bale chamber rotation speed.
To programme the electronic controls for the maximum
speed repeat the same process again BUT
