Mounting of die cutting cylinder

1. Remove the switch sensor, avoid to be damaged when change the cylinder.

2. Mount the bearing block on both side of cylinder.

3. Hang up the cylinder by using special tool.

4. Use different thickness of holding pieces into the frame rail, then put the cylinder

into die cutting unit, the bearing block need to be put down from the frame rail.

5. Mount the pressure bridge kit, them Check and make sure the gear can be

matched each other when pressure on.

6. Mount the switch sensor again, scan distance is 1mm. make sure the sensor flash

on time during cylinder turn one repeat.

SDF-E330 Manual

Dismounting of die

1. Jog machine slowly and find the top of die.

2. Take off the die by Jog machine slowly.

Mounting of die

1. Clean the cylinder with I.P.A.,

2. Jog the machine slowly and find the mounting line.

3. Mount the die from the mounting line.

(Remark: the beginning of cutter line on the die must match the mounting

line)

4. Jog machine slowly, mounting the die on the cylinder.

Operator setting

In semi mode, the potensiometer is not availble for speed turning.need press +
and – to adjust RPM(Repeat per minute), 220RPM is the maximum speed.

In Full mode, the potensiometer is for the speed turning.

Make sure the correct web path is ready before operate this press, please follow

the web path drawing.

1. In touch panel, go to mode setting, press full-rotary, then change the mode to

be “Semi Mode”, input repeat length and reset.

SDF-E330 Manual

Semi-rotary set up procedure:

1. Change to semi node

2. Write down the repeat length

3. Reset

4. Turn ON

The gap “0.00” is to use for the gap adjustment between repeats, for different
distortion and running speed.

Write length of die into “Repeat” box, then press “Reset”.

For example (Please see the image)

One label only in die, the length of label is 106mm, the gap between labels is

8.3mm, Total length is 114.3mm, So input value “114.30” into this box.

1) If two labels in die,input “228.60” to this box. and input “342.90” for three

labels.

2) Then press “Reset”,to make sure it is working, you can press 2,3 times.

3) Press ”reset”, the dancing unit start to move one cycle, stop in zero position.

7) Turn ON, Done.

Sensor setting:

Eye mark sensor
1, Make sure that web path is ready for running.
2, Jog machine, and let sensor detector scan non-printing area. press button
“BKGD” on sensor for 3 seconds, green light will off, then release.
3, Jog machine ,let sensor detector scan the mark printed on material,
4, Press button “MARK” 1 time, the orange and green light will on.
5, Jog machine, the sensor green light is always on, the orange light will twinkle
when meet marks.
6, Sensor setting is ready.

Switch pin sensor:

The distance to detect the pin is 1mm nearly. Please be careful, Do not break

the sensor by plate cylinder when run the machine.

The sensor will light on one time when cylinder turning one repeat.

Sensor setting is ready.

Remarks:

Sometime you find the actual position box always “0” or this value stable no

change, it maybe the eye mark working mode has changed.
Please change it back will be OK

Keep press the sensor’s two button more than three seconds, then release , you

will see a green light flash 3 times(must see the green light flash). so the mode

There are two working mode by sensor, one is output 0v, the other one is output

24v, only the first one can be used for us.

Registration operation

Go to registration setting (this is 3units configuration).

Button description:

The repeat adjustment(±1000) is use for sometimes the die cutting repeat length
is little bit/ smaller. Do some adjust could matched it.

1, Make sure the sensor is ready.
2, In repeat mark box, check the value, meaning how many marks are detected in
one repeat(during cylinder turn one repeat)

1) Check or reset the eye mark sensor, make sure the orange light twinkle one
time when one mark coming in.

2) Check the switch sensor which detect the pin on cylinder.

3) check the eye mark sensor working mode

4) Check if the repeat of job and cylinder are matched each other.

This value must be stable. Please check below if it is not stable or always “0”.

SDF-E330 Manual

1. Adjust the registration manually by touching both-direction arrow.

2. When the registration is ok, turn on the registration to AUTO mode.

Remark: “ON ” is auto-registration . “OFF” is manual-registration.

3. In auto-registration mode, can adjust the registration by the arrow.

This is for mm when move one step:

4. See the registration tolerance , it should be keep near around “0”.

Pre-register setting

Before using pre-register,
If you want to use full-rotary, please set machine to full-rotary.
If you want to use semi-rotary, please set semi-rotary die cut right.

(including repeat length and cylinder tooth number).

Check if the sensor catch the mark.

1. check the main interface, there is a Pre-register (as shown), press in.

SDF-E330 Manual

2. check the mark position(as shown), it means the distance between your first cut
line and your mark. Set it. At first, it should be 0.

3. Please make sure the magnetic cylinder engaged but not too much pressure,do

not let the knife touch the paper. Press reset, machine will auto running to find the

homing position (the magnetic cylinder rotated around while detect the cylinder
sensor, machine running little bit).When machine stop, it should be almost in the
right position which you need. Increase pressure,Then low speed to run the machine,
please pay attention to the current die cutting position and back to the registration
setting window, there has a number display in the actual value box. Running 3-5
repeat later, to check the repeat mark ,if stable,then on A/M switch,if there is a little
tolerance, use auto to adjust it.

Troubleshooting

Die cutting pressure issue

1. Check the flexible die is correct for the magnet cylinder.

SDF-E330 Manual

2. Check the pressure, and the releasing pieces are using correctly

Printing pressure problem

1. Check the air pressure is enough for engage/disengage of plate cylinder

2. Check if the right thickness of plate is used.

3. Check the pressure arm and knob.
