ONE 7TS – Operation and use
4) Press the start button. If the electrical panel is supplied by
GEA Niro Soavi S.p.A. this operation will
will enable the machine to be started according to the correct sequence, depending on the type of ma-
chine and of the optional equipment:
- opening solenoid valves for utilities (optional);
- starting main motor.
If the electrical panel is supplied by the customer, the correct operating sequence will be provided (See
TECHNICAL SPECIFICATIONS enclosed in chapter 11 of this manual), and this sequence should be ob-
served scrupulously.
6.3.3 Operation and adjustment
For a few minutes after the machine is started do not increase homogenizing pressure and check regular
operation and, in particular, the value of feed pressure and its stability within the limits indicated in the
TECHNICAL SPECIFICATIONS enclosed in chapter 11 of this manual.
You can now use the controls to set the homogenizing pressure to the required value.
To find out whether the system includes the second homogenization stage see the TECHNICAL
SPECIFICATIONS enclosed in chapter 11 of this manual.
6.3.3.1 Adjustment of homogenization pressure - 1 stage
This type of adjustment uses a servosystem which by means of a pneumatic cylinder acts on the position of
the homogenizing valve to determine homogenization pressure.
On the front panel of the machine (see figure 6-4 below), there is a pneumatic switch (A) and a pressure re-
ducer (B).
The adjustment operations are:
•
check that the pressure reducer (B) is completely loosened
•
pull the pneumatic switch to the ON position;
•
rotate the reducer to obtain the required homogenization pressure; this value can be checked on the
pressure gauge located on the head.
ATTENTION:
Slowly rotate the pressure regulator and check that the homogenization pressure is actually increas-
ing up to the operating value.
ATTENTION:
Check the increase of air pressure on the pneumatic head on the pressure gauge installed on the
control panel; this makes it possible to verify the slow increase of homogenization pressure. It is
also possible to use the air pressure gauge as a reference if the pressure gauge on the head is not
working correctly.
Once the homogenization pressure has been set to the required value you can block the reducer knob (B) by
pressing it.
