Foreword
This instruction manual is intended to help the user to become familiar
with the machine and take advantage of its application possibilities in
accordance with the recommendations.
The instruction manual contains important information on how to
operate the machine securely, properly and economically. Observation
of the instructions eliminates danger, reduces costs for repair and
down-times, and increases the reliability and life of the machine.
The instruction manual is intended to complement existing national
accident prevention and environment protection regulations.
The instruction manual must always be available at the machine/sewing
unit.
The instruction manual must be read and applied by any person that is
authorized to work on the machine/sewing unit. This means:
– Operation, including equipping, troubleshooting during the work
cycle, removing of fabric waste,
– Service (maintenance, inspection, repair) and/or
– Transport.
The user also has to assure that only authorized personnel work on the
machine.
The user is obliged to check the machine at least once per shift for
apparent damages and to immediatly report any changes (including the
performance in service), which impair the safety.
The user company must ensure that the machine is only operated in
perfect working order.
Never remove or disable any safety devices.
If safety devices need to be removed for equipping, repairing or
maintaining, the safety devices must be remounted directly after
completion of the maintenance and repair work.
Unauthorized modification of the machine rules out liability of the
manufacturer for damage resulting from this.
Observe all safety and danger recommendations on the machine/unit!
The yellow-and-black striped surfaces designate permanend danger
areas, eg danger of squashing, cutting, shearing or collision.
Besides the recommendations in this instruction manual also observe
the general safety and accident prevention regulations!

6. Pneumatic connection
For the operation of the pneumatic components the sewing unit has to
be supplied with anhydrous compressed air.
ATTENTION !
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
operating pressure must not drop below 6bar.
In case of a too high loss of pressure:
–
Increase the compressor output.
–
Increase the diameter of the compressed air hose.
1
3
Connecting the maintenance unit for compressed air
–
Connect the connection hose (Order No. 0797 003031) to the
pressure regulator 3 by means of a hose coupling ¼ “.
Adjusting the operating pressure
–
The operating pressure amounts to 6 bar.
It can be read off at the manometer 2.
–
For adjusting the operating pressure lift the twist handle 1
and turn it.
–
Turning in clockwise direction = the pressure is increased
–
Turning counter-clockwise = the pressure is reduced
2
16
ATTENTION !
No oil-bearing compressed air must be fed from the compressed air
line.
Behind the filter cleaned compressed air is withdrawn as blowing air
for cleaning machine parts and for blowing workpieces out.
Oil particles contained in the blowing air lead to malfunctions and
stains on the workpieces.
Page 21
7. Oil lubrication
32
Caution: Danger of injury !
Oil can cause skin r ashes.
Avoid longer skin contact.
After contact wash yourself thoroughly.
ATTENTION !
The handling and disposal of mineral oils is subject to legal
regulations.
Deliver used oil to an authorized collecting station.
Protect your environment.
Be careful not to spill any oil.
For filling up the oil reservoirs use nothing but DA-10 lubricating oil or
an equivalent oil with the following s pecification:
–
Viscosity at 40° C: 10 mm
–
Ignition point: 150° C
DA-10 is available from the DÜRKOPP ADLER AG sales offices under
the following parts numbers:
250 ml Container: 9047 000011
1 l Container: 9047 000012

Caution: Danger of injury!
Switch off the main switch before threading in needle and hook thread.
Laser light.
Do not look into the light source.
–
Thread in the needle thread (see Operating Instructions
Chapter 2.5).
–
Thread in the hook thread (see Operating Instructions
Chapter 2.7).
–
Switch on the main switch.
The control is initialized.
–
Step back on the pedal.
The reference run starts.
The transport carriage moves in its rear end position.
The reference run is necessary in order to get a defined initial
position of the transport carriage.
–
By actuating the pedal the various steps of the positioning
procedure are triggered sequentially and the s ewing cycle is
started.
9. Software installation
9.1 General
ATTENTION !
At the sewing start the workpiece must lie under the feeding clamps.
Movement of the transport carriage without material damages the
coating of the feeding clamps.
–
For selecting the sewing program and for further settings of the
control unit s ee Part 4: Programming Instructions 745-34
Speedpocket.
–
Positioning and operation are described in Part 1: Operating
Instructions 745-34 Speedpocket.
Loading a specific sewing software in the DACIII control unit is
possible with the help of the “Programmed Dongle”. The “Programmed
Dongle” has a label indicating the class and software version.
Such a loading (booting) may be used in o rder to provide several
DACIII control unit with a sewing software (first installation) or to install
a newer machine software (update).
18
Page 23
With the delivery of the machine only the test software (allowing the
loading of sewing software) is installed in the control unit.
The test software offers no further functions. If the test software gets
damaged during the loading process, it is no longer possible to load a
software using a dongle.
In such a case use a PC with the loader cable.
Important !
The machine software is already included by the delivery of the
sewing unit.
CAUTION !
Turn off the main switch before connecting the dongle.
9.2 Loading the program
–
Turn the machine off at the main switch.
–
Insert the dongle 2 into the socket X110 (TEST-Interface) 1 of the
control unit (see pictures).
–
Switch on the main switch. The Software will be loaded. The
loading process takes less than 60 seconds.
–
During the loading process do not r emove the dongle and not
switch off the machine (you will damage the Software) !
–
During loading the program version of the operation panel will be
displayed, e.g. “BF4 A02”.
–
When loading is completed the new program version will be
displayed, e.g. “745 A01”.
–
Remove the dongle 2 of the X110.
–
For safety reasons: please confirm the new operation program
before the first start of the sewing unit with the button ”OK”.
–
The machine is now ready for use.
Important !
Remove the dongle before the next switch-on, otherwise the sewing
software will be reloaded again.
After exchanging the DAC III control box and loading the machine
software, the following messages will appear, Error 9900 or Error 9901
or Error 9902. In the next step a complete reset of the machine
software must be done.
Please follow part 4 chapter 6 of the programming instructions.
In this chapter under the menu item 504 all parameters for machinepocket parameters and sequence are set to default values.
Then the machine parameters 400 to 407 must be accordingly.
