1. Safetyinstructions
This chapter describes the safety guidelines that must be observed under all circumstances when
installing,commissioning, operating and maintaining the CONVERTING UNIT.
In this operating manual and on the unit, the followingsymbols will draw your attention especially to
hazards, risks and safety relevant information:
Indicates a potentially dangerous situation. Non-observance of the warning instructions
may lead to slight or medium personal injuryor damage to machine.
Indicates a potentiallydangerous situation. Removal of the cover behind this symbol
may lead to direct or in-direct exposure to high-voltage parts. This may lead to fatal
personal injury.
Indicates a potentiallydangerous situation. Possible trapping of hand between rotating
rollers. Removal of the cover behind this symbol may lead to slight or medium personal
injury.
Indicates a potentiallydangerous situation. Possible trappingof hand between rotating
rollers with sharp points (gears or other blunt parts). Removal of the cover behind this
symbol may lead to slight or medium personal injury.
Indicates general instructions, useful tips for application and recommendations for
working that do not have any influence on the safety and health of the personnel.

2. DC330mini/nanonote
This manual is for the DC330mini and the DC330nano
The DC330mini line is identical to the DC330 –only difference is that it is much more compact. The
DC330 nano does not have a flexo unit –it is lamination only.
The DC330mini & Nano can’t operate inline without a buffer module installed.
3. Controlpanel
The control panel is fitted with a touch panel, and on the right side, the POWER button, EmergencyStop
button, the four torque adjustment knobs, and the speed button .
The symbols indicate which spindle a torque control knob is related to.
On the side of the controlpanel, the manometer adjustment for knife and nip is placed.
To power up, first check that the main switch is turned ON, and the Emergency Stop buttons are released.
Press the POWER button. The touch panel will light up.

4. Touchpanel
The touch panel is the main control unit on the converting unit. All values regarding a job are entered
through the panel. It responds to light pressure onto the panel, thus responding when the user pushes a
virtual button or numeric value shown in the panel.
NOTE! Never hit the touch panel.
Do not press with sharp objects.
To clean the touch panel, soak a cloth inwater with a mild detergent, wring
the cloth tightly and wipe the panel. Never use strong detergents, paint
thinner, organic solvents or acid on the panel.
When the machine is turned on, the panel will light up, and after a few seconds the startup screen
emerges:
In the upper right corner, software versions are printed. This can be useful in maintenance situations.
To set language, units and clock, press 'Setup' (see appendix). To continue to the main screen, press
'Startup'.

5. Themainscreen
The majority of machine functions are operated on the main screen. A large graphic representation of the
machine is used for controlling:
•mandrel expansion
•spindle modes
•nip rollers
•varnish roller
•die-cut cylinder
•UV lamp
A number of buttons, checkboxes and readouts are placed on the lower part of the screen.
The converting unit is equipped with four spindles with different functions:
•Unwinder
•Waste rewinder
•Rewinder 1 (top)
•Rewinder 2 (bottom)
Each spindle will change mode when the attached rotation mode button is pressed. Two of the
spindles can run in both directions (the two main rewinders), and the rest can run in only one direction.
All spindles can be turned off.
When the center of a spindle is pressed, the air operated mandrel will expand (lock) or release.

5.1. Webentry
The web entry into the machine can be run in two different modes:
In Stand-alone mode, a roll is placed on the unwinder, labels out or labels in. The web must be fed
through the DCmimi buffer, which creates web tension, and controls the unwinder.
In Inline mode, the web is fed into the DCmini buffer and into the DCmini converting unit from another
machine, e.g. a print engine. Again, the web must be fed through the dancer, which now controls the web
speed together with the speed knob on the control panel.
5.2. Thevarnishstation
The varnish station contains the input nip roller and the varnish unit. Under normal operation, the input
nip must always be turned on, in order to create web tension. The nip roller is turned on and off by
pressing the small nip symbol in the lower part of the varnish station. Nips are coloured green when they
are off, and yellow when they are on.
The varnish roller can be engaged and released bypressing the roller symbol on the top of the varnish
station. It can also be turned on and off automaticallywhen the web starts and stop. If the feature
'Automatic varnish roller' is turned on, the varnish roller will be engaged when the web moves, and
released when the web stops.
5.3. Thespotvarnishoption
If the spot varnish option is installed, the varnish station can be used for full-rotation spot varnishing,
with varnish rollers from 10 to 19". In addition, a "slow run" feature is available, which is suitable for
varnish types which are not UV varnish. The spot varnish features are accessed in the Parameter menu.
5.4. Thelaminatingstation (optional)
The laminating station is a coldfoilstation.
It consists of two spindles, with the laminating nip and the UV lamp in between.
The laminate unwinder is above the UV lamp.
When laminating, the laminate nip roller will press the foil against the web. This nip roller can be
engaged only if the laminate unwinder is activated.

This is to prevent the rubber roller from accidentallybeing pressed into wet varnish or glue.
The pressure that the laminating nip applies onto the web can be adjusted with the air pressure regulator.
The pressure gauge will onlydisplay the pressure when the nip is engaged. If the regulator is turned all
the way to zero, the nip will not move when activated. A typical pressure setting is 1-2 bar.
The laminate unwinder will not rotate when the laminate nip is off. This is to prevent the laminate foil
from rotating freely through the laminating station.
For the DC330Mini, the following images illustrate the web path if running with an adhesive laminate
and the web path if running with supergloss laminate.
For the DC330Nano the image below illustrates the web path (in blue) for self adhesive laminate.
