6.5 Pneumatic connection
For the operation of the pneumatic components the sewing unit has to be
supplied with anhydrous compressed air.
In case of a too high loss of pressure:
• Increase the compressor output.
• Increase the diameter of the compressed air hose.
The connection to the compressed air supply is effectuated with the ac-
cessory delivered as optional equipment or with in-house fitting material.
Operating pressure (2) = 6 bar
Blowing pressure (1) = Has to be adjusted according to the sewing
material standard setting 3 bar
Material damage!
For a trouble-free function of the pneumatic control procedures the
compressed air supply must operate as follows:
Even at the moment of the highest air consumption the minimum op-
erating pressure (2) must not drop below 6 bar.
ATTENTION
Material damage!
No oil-bearing compressed air must be fed from the compressed air
line. Behind the filter cleaned compressed air is withdrawn as blow-
ing air for cleaning machine parts and for blowing out workpieces.
Oil particles contained in the blowing air lead to malfunctions and
stains on the workpieces.
