8.4. Setting the air pressure
The optimum result is obtained by three pressure settings.
Settings must be affected on the following pressure controllers:
DR 1
Pressure controller on the machine
(Main controller)
DR 2
Pressure controller on the
multi-functional block
DR 3
Pressure controller on the multi-
functional
block
1.
The pressure controller
DR 1
is found on the maintenance unit of the machine.
The maintenance unit provides for the quality of the compressed air. It filters water, oil
aerosols as well as dirt and rust particles from the air and provides the entire machine
with sufficient air pressure. It should be able to discharge oiled and unoiled air.
In case of high level differences between
the maintenance unit and the strapping
head or a hose being longer than 5 m a
separate oiler
(700)
has to be installed
near the head.
If the machine is without air supply, the maintenance unit-depending on the installation
position of the head must be attached directly to the head or immediately near it
Port cross section:

DR 1
can be set at an impact pressure of
6,0 to 7,0 bar
