1 About this document
The control unit "Danfoss Control C.2" is consistently designated as
control in this Operation Manual.
This Operation Manual includes important notes on how you operate
your machine and control safely, properly and economically.
1.1 Storage
This Operation Manual is a document also applicable in connection
with the Operation Manual of the machine, therefore represents an
integral part of the machine and must be kept available at the ma-
chine at any time. Upon disposal of the machine, the Operation Man-
ual must also be handed over.
1.2 Figure presentation
Most figures have two areas:
•Value setting (1)
•General buttons for navigation in the menu bar (2)

The individual elements in the figures are described from left to right
and from top to bottom.
The values shown in the figures are given as examples and may
differ from actual values - depending on the machine type and the
individual selection in the basic settings.
If another user interface (*.xml file) is being used than the one de-
scribed in the Operation Manual, the affected Operation Manual
must be observed.

2 Safety instructions
2.1 Presentation of warning notes
Warning notes in the Operation Manual warn against risks involved
with the handling of the machine. Risk levels are identified as follows:
The signal word HAZARD identifies an imminent hazard resulting in
serious injuries or death. This warning is supplemented by a triangu-
lar hazard symbol.
The signal word WARNING identifies a potentially hazardous situa-
tion, which might result in serious injuries or death. This warning is
supplemented by a triangular hazard symbol.
The signal word CAUTION identifies a potentially hazardous situa-
tion, which might result in light injuries. This warning is supplemented
by a triangular hazard symbol.
The signal word ATTENTION identifies a potentially hazardous situa-
tion, in which the product or property in the environment may be dam-
ages. This warning is supplemented by a hazard symbol or a excla-
mation mark.
2.2 Safety instructions
2.1 Use in compliance with intended purpose
This control unit is intended for industrial applications, only to be used
to control the supplied UNIFLEX machine.
Intended purposes include:
•Operating temperature between 10°C and 45 °C;
•Operation in a closed room.
Use of the machine in compliance with the intended purpose also in-
cludes compliance with the instructions in this Operation Manual.
Use not in compliance with intended purpose
Any other use is considered as not in compliance with the intended
purpose, in particular:
DANGER!
WARNING!
CAUTION!

(2) Open machine pedal
WARNING!
Risk by fatiguing posture!
A static posture may result in work-related musculosceletal disor-
ders and reduce productivity.
•Make sure that operators have sufficient periods of relief and
recreation.
3.3 Operation modes
The control provides for the following operation modes:
•Manual operation
is activated in the control. The forming process is controlled
manually via the buttons on the control panel or external but-
tons, e.g. the dual foot switch:
–Buttons Close tool and Open tool .
–Dual foot switch
The right foot switch is used to close the tool and activate

the forming process, the left foot switch is used to open the
tool.
–Depth stop
The tool is closed automatically when the workpiece acti-
vates the depth stop by pressure. Press the button to
open the tool.
As soon as the forming diameter or forming pressure defined in
the control is reached, the tool stops automatically.
•Semi-automatic operation
is activated in the control. The forming process is started
manually via the buttons on the control panel or external but-
tons, e.g. the dual foot switch:
–Close tool button
–Dual foot switch
The right foot switch is used to close the tool.
–Depth stop
The tool is closed automatically when the workpiece acti-
vates the depth stop by pressure.
As soon as the forming diameter or forming pressure defined is
reached in the control, the tool stops and opens automatically.
Production is possible in any operation mode.
The operation mode selected before deactivating the machine will
be active upon a restart. The operation modes are set on the con-
trol panel.
When the Foot switch button is activated, the Close tool but-
ton is inoperative, even if it is illuminated.

3.4 Control operation
The control features the following elements:
•Buttons (blue circle)
•Input fields (white field)
•Value display (on grey background)
The control is operated via the control panel:
Tip on the relevant control element,
•either with finger, or
•with a suitable pointer.
ATTENTION!
Risk of damage to machinery!
Hard objects or objects with sharp edges may scratch the screen
surface.
•Do not use any sharp-edged or hard objects to operate the
control.

If figures or letters have to be entered, a keyboard or number field
showing the permissible range of values will be displayed after touch-
ing the control panel.

4 Start screen
The following control screens are opened from the start screen:
Workpiece table
Crimp without workpiece table
Machine settings
