Setting the top and end positions
When the Mini Roll Down is ready, the first step is to set the soft-limit top and bottom positions.
See channel description for channel 4, 5 and 6 above. When the range has been set once on
channel 6 it is saved and does not need to be set again unless a new range is needed.
Example:
−
DMX channel 4 is set to 62%
→
Soft-limit save enabled.
−
DMX channel 5 is set to 30%
→
The roll starts moving up.
−
DMX channel 5 is set to 0%
→
The roll stops, and the soft-limit top position is saved at
this point.
−
DMX channel 6 is set to 30%
→
The roll starts to move down.
−
DMX channel 6 is set to 0%
→
The roll stops, and the soft-limit bottom position is also
saved.
The Mini Roll Down is now ready for use and the soft-limit top and bottom positions have been
saved. Finally, the position control with channel 1 and 2 is now relative to the top and bottom soft-
limits settings.
It is recommended to set the soft-limit top position after each power-up, however, moving the
roll to the top position before powering off should lead to identical top and bottom positions
whenever the unit is repowered, provided that the drum position was not manually changed or
the drum return to the top position was interrupted by a power failure, furthermore excessive
transportation conditions may also affect the drum position.
For further guidance see below illustration for application of the soft-limits.
