7.3.1 Knife operation
Standard knife operation
allows all 15 (or 25) knives to be raised/lowered together.
If
Manual mode
is selected there are two buttons for controlling the knives on
Screen 2.
1.
Button R3 lowers all of the knives
2.
Button R4 raises all of the knives
Standard knife operation (Manual, Screen 2)
The knife pressure in bar
is displayed in the top centre panel of Screen 2. When the
knives are raised the pressure will increase and stop at the normal working pressure,
approx. 50 bar.
Sometimes, if the knives have not been used for a while, full hydraulic pressure may
need to be used. To do this, the ‘knives up button’ (R4, Screen 2) should be pressed
and when normal working pressure is reached, it should be released and then pressed
again.
The pressure will then increase to the maximum allowed and a ‘Knife pressure too high’
warning will be displayed to warn the operator not to bale with the pressure this high.
To release the pressure, lower the knives fully by pressing ‘knives down’ (Button R3,
Screen 2).
In
Automatic mode
, Button R1 is toggled to select the number of knives desired, 0 or
15. The machine will automatically move the knives to the correct position and
constantly monitor the knife pressure and correct it, as necessary.
A sensor indicates when the knives are fully up. The knife symbol will be shown as
follows:
Manual wrapping
Buttons L5 and R6 on Screen 2 (Manual Mode) are
used to manually rotate the wrapper ring. Pressing

(Button R6) or reverse (Button L5)
once will rotate the ring slowly. Pressing forward
(Button R6) twice and holding it
will rotate the ring
forward at full speed.
