THE ROLLERS WIDTH DOES NOT WORK.
a)
Does the magnet valve enough electric power?
With many power consumers at the same time, the voltage can fall so much that all
functions, or only the width-function does not work.
b)
Check the master valve. (Pos. 7, fig. 14-1).
If it gets enough electric power and closes the oil flow, the failure has to be found in the
magnet valve for rollers width. (See chapter 16.1).
17.6
THE WRAPPING ARM IS ROTATING, BUT THE ROLLERS ARE NOT.
Check first that the flow control valve for rollers is not closed. (Fig. 9-1).
If the valve for rollers width, (3-4), fig. 14-2), are not in order, the oil that shall rotate the rollers can
leak out through this valve, so the roller-motors are losing their power. To be able to loosen possible
mote, the valve can be operated manually with a screwdriver at the end of the valve.
(See chapter 16.2).
17.7
THE CUTTER DOES NOT LEAVE THE FILM WHEN THE MACHINE IS TESTED WITHOUT
LOAD.
The reason for this is that when the cutter is closed with maximum pressure it might be difficult to
obtain sufficient pressure to open the piloted non-return valve, (underneath pos. 9, fig.14-2), if the
machine is empty, i.e. wrapping arm and rollers unloaded.
This will not happen while wrapping with a bale on the machine. If this should occur when testing
without a bale, it can be avoided by not having the cutter closed with full pressure. Give a short push
on control no. 5,
CUTTER up,
enough to release some of the pressure.
