Problem:
-
Roll change cycle stop when the load arm is without roll on the winding drum
Frequent problems with load arm positioning.
Incorrect load arm angle after the encoder has been calibrated and load arm
was moved.
Reason:
-
Mechanical problem
Wiring problem
Encoder internal problem

Model: all Evolution winders
1. Check the mechanical setup from the load arm (without winding shaft) /
switch off the main power if you need to adjust this!!!
This small gap should be only 1-2mm.
The cylinder shaft is locked by a small screw from the bottom side
This distance should be 70-72mm

Since July 2019 is also a modification set available, this can be used also at the
2nd unloading system. For each winder station you will need following parts
2x 97035618
2x 81004742
4x 480032
4x 406014

Encoder calibration
Make sure that you have carefully completed all the steps of the encoder
calibration procedure. As a reference, this guide is added to the end of the
manual.
2. Locate the encoder
Remove the cover on the control panel side, and locate the encoder (1).

3. Check the torque arm support
As a result of a loose or broken torque arm the whole encoder moves with
load arm movement. This leads to wrong angle measurements.
4. Check axis connection clamp
As a result of a loose or broken axis connection clamp the axis slip over during
load arm movement. This leads to wrong angle measurements.
! A broken axis connection clamp can be fixed or replaced with a slim hose
band clamp.

Check also the proper connection from the center bolt.
5. Check plug
Must be plugged in and secured.
6. Encoder calibration
Calibrate the encoder. As a reference, this guide is added to the end of the
manual.

7. Function test
o Open the Info page (1) on the winder PP65.
o Press the screen in the marked area (2) to open the enhanced Info
page.
o Note the actual load arm values (in base position).
o Move the load arm complete down and up in manual mode for 6-10
times.
o Go back to the enhanced Info page and note the actual load arm
values.
8. Result
Compare the noted values before and after manual movement.
Values are equal
o The encoder and all mechanic / electric connections are ok.
Values are unequal by 0,xx
o The encoder and all mechanic / electric connections seem to be ok.
In base position the load arm lay on rubber rings. This may lead to
small deviations in the base position values.
o Move the load arm again complete down and up in manual mode for 610 times then check/note the values on the enhanced Info page.
o If the deviation increase there is a problem with the encoder.
Values are significant unequal
o The encoder seems to be broken. For an additional test you can swap
the encoder between winder 1 and winder 2 (if 2 winders are available).

Encoder calibration instructions


Take care that 6bar air pressure is on the winder and the winding drum is in
max. front position
Insert a 6” winding shaft into the load arm (or a winding shaft with a film roll
which have got a diameter upper 140mm diameter) and bring the arm to the
base position that the winding shaft or the film roll touch the winding drum
roller.
 go to the touch screen of the winder and click the right arrow
Click the Service button

Enter the password 9020 and after that (2) click the left service button
Fill in the diameter from the winding shaft (or the film roll) which is in the load arm to
teach the winder to this diameter
Press the Button for encoder calibration
Confirm the calibration
