the attached shutters. At this point the Shutter can be moved up (open), but can't be moved
down, because this position is already set as its lowest position.
To change the defined lowest position of the Shutter below the one, which is already defined
(manual recalibration), the parameter 74 must be set to 0 and the procedure, which is described
above, should be repeated.
In case the Shutter operates using limit switches, but the user still wants to control the
opening/closing position with time, this is still possible. If a time duration, which is longer than
the opening/closing time of the shutters in real time (limited by the limit switches), is set, the
Shutter will stop at the limit switches, but the device relay will switch it off after a defined time,
not by the limit switch of the Shutter. Take into consideration that in this condition, positioning
the shutters with the slider (through the UI) will not display the correct position of the Shutter.
