Functions of the illuminated button
There are several functions for the illuminated button a:
– Switching the unit on/off
– Teaching the angle sensor
– Error indication via blink codes
For these
functions see the following table, or respective sections.
Note: When applying power the unit gen
erally is READY, i.e., switched on, the button is lighted.
Pressing the
bu
tton
Action / Function
< 3s 1. Switching the unit on if it is off.
2. Resetting the unit if an error occurred (indicated via blink code; see below).
> 3s und < 10s Switching the unit off.
Note that on applying power the rewinder will turn immediately if at that time
no
backing paper is inserted. Rotation will stop automatically after a short period of time.
Teaching the angle sensor
As the case may be, e.g. in case of a new unit, you may have to teach the unit the positions of the
pendulum if this is released completely and if this is moved to its maximum deflection in order to
ensure a correct function and to avoid errors. For teaching the unit proceed as follows:
> Disconnect the unit from mains.
> Clear the unit (no web inserted).
> Press the illuminated button and keep it pressed while applying
the power supply. Keep on pressing
the button. This will blink at low frequency.
> Push the pendulum a little more towards its rel
ease position (completeley untensioned).
> Let the illuminated button go. This will now blink at
a higher frequency, i.e., in more rapid
succession.
> Now move the pendulum to its stop in the tensioned
position , i.e., to its maximum deflection. Press
the button briefly. This will blink again in slow succession. Thus, teaching was successful.
> For completing the procedure disconnect the unit from mains and consequently apply power once
more.
If
teaching was not successful an error code will be issued (see below) and the procedure must be
repeated.
