Description
The mini Roll Down is for stage use, mainly for use in theatres, shows, and concerts. It lifts small
curtains, projector screens, or similar in and out of the stage sphere at maximum load of 7.0 kg
for the slow variant and 3.0 kg for the fast variant. The length of the drum depends on the
application and can easily be changed. Two different versions have been developed, which vary in
maximum lifting speed. The slow version has a lifting speed of 2.5 to 26 cm/s, while a faster version
has been developed with a lifting speed up to 61 cm/s. Both versions are highly accurate and stop
within 2 mm of the target position. Multiple Mini Roll Downs can easily be connected, as a chain,
allowing for advanced and creative ways of making dynamic movements.
The two versions are controlled in the same manner. Typically, through 6 DMX channels from a
lighting desk where the position and speed can be changed live or pre-programmed as wished.
Through the lighting desk the top and bottom positions can also be set. Furthermore, the Mini Roll
Down can be controlled using a Manual Control Box from Wahlberg Motion Design, or
alternatively manually through mode 9 or 0.
Safety functions
The control system ensures that the motor is only powered when:
•The DMX signal is reliable.
•The speed control channel is on (more than 0%).
•The motor is instructed to move.
•No overload.
The Mini Roll Down should only be operated by an experienced lighting-desk-operator. The
lighting desk must be programmed according to the manual, so the Mini Roll Down will stop when
the speed is put to 0 %. It is also possible for the user to stop the Mini Roll Down by disconnecting
the mains power. After Power interruption the top position of the Mini Roll down needs to be
reset before the Mini Roll Down can function again
