Error

Possible cause

Remedy

Container builds excessive
pressure during operation and/
or when the system is stopped.

Ventilation connection of the fill
head closed or ventilation line
not free (e.g. blocked particle
filters, blocked valves, kinked
line).

Check and clear the entire
ventilation line, replace
particle filter or valves if
necessary.

Ventilation of the container is
not sufficient to achieve com-
plete pressure equalization.

Reduce the filling flow rate
of the operating medium,
Increase the nominal
diameter of the ventilation
line,
Shorten the length of the
ventilation line,
See also Chapter 5

Container contracts when the
system is stopped.

Ventilation line is connected to
a suction system, which creates
excessive negative pressure in
the container.

Take suitable precautions
on the system side to pre-
vent negative pressure,
e.g. reduce the negative
pressure in the extraction
system.
