16.0 TROUBLE SHOOTING.
16.1
THE MACHINE DOES NOT FUNCTION.
a)
Even if the gauge shows enough pressure and there is no reaction in the machine. The
reason could be that one, (or both), of the quick-couplers does not open for the oil.
Change quick couplers.
b)
The counter pressure could be too high.
Max. allowed counter pressure is 10 bar.
(See chapter 14).
c)
Make sure that the open / closed valve is correctly positioned.
(Disturbances of this type, a, b or c, are most likely in the first days that the machine is in use).
16.3
THE CUTTER WILL NOT HOLD THE FILM.
The pressure is falling and the springs start to lift the cutter. (See chapter 14.2).
16.4
THE WRAPPING ARM WILL NOT ROTATE.
a)
The bolt that secures the wrapping arm during transport has to be removed so that the
wrapping arm can move freely.
b)
Check valve 1. (See fig. 13-2). Screw all the way in and test. Adjust to required power.
c)
The safety valve, (S3, fig. 13-2), can be leaking, so that the oil is passing by the wrapping
arm motor. Dismantle and try out if the sliding shaft can move freely .
d)
The control valve, may be blocked. Dismantle and check if the valve works normally. Do not
use sharp tools
e)
Check if the oil motor is working
Ask your dealer for advice BEFORE you make the problems bigger and repairing
more difficult
f)
If the emergency stop* has been activated. To start the machine the control box must be
reset (See also chapter 5.0).
16.5
THE ROLLER WILL NOT ADJUST.
I.
Is the Solenoid valve receiving enough electric power ?
When the power source is tapped by several users at ones, the voltage can fall so much that all the
functions will cut out, or only the width regulating. Check the power source and measure the
voltage.
I.
Check the bypass valve
If this is receiving enough power and has free flow, the problem must lie in the solenoid valve.
