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:
Risk of electric shock! Disconnect all sources of supply and wait for five
minutes before opening the rear cover or touching the connector pins!
Electrocution may occur.
> 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 release 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. See as well the corresponding error messages in chapter 11.
The factory-set maximum deflection of the pendulum may constructionally
be decreased by a maximum of 20° since otherwise full functionality cannot
be assured.
Activating the Smooth Mode
For some applications operation of the winder (here: the motorized unwinder) is preset with too high a
dynamic. For this purpose the winder can be made „more gentle“, i.e., acceleration and deceleration of
the unit will be effected less roughly. For such setting proceed as follows:
> Press the blue illuminated button and keep it pressed for more than 20 seconds. During these 20
seconds the button will blink at low frequency first and then at high frequency.
> As soon as the illuminated button blinks at high frequency move the pendulum to its tensioned
position.
> Let go of the illuminated button.
> Move the pendulum to its released position.
> Press the illuminated button once more. The winder is in the Smooth Mode.
To set the winder back to normal mode go through the same steps once again.
