Description
The product is for stage use, mainly for use in theatres, shows, and concerts. It controls 3 phase
AC motors (not included) to move props and small set pieces or similar in and out of the stage
sphere with a motor rating up to 4HP. Multiple products may easily be connected as a chain,
allowing for advanced and creative ways of making dynamic movements.
The product is controlled through 4, 6 or 10 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. However, several hardware options are available
to meet the specific application e.g. using an external encoder, applying external switches to
limit the movement, and using an AC motor brake when the gear is not dynamic self-locking with
the applied load.

Safety functions

The control system ensures that the motor is only powered when:

The DMX signal is reliable.

The motor enable channel is in the operation range.

The speed control channel is on (more than 0%).

The motor is instructed to move.

No overload.

The Emergency input is active and enabled
The product should only be operated by an experienced lighting-desk-operator. The lighting desk
must be programmed according to the manual, so the unit will stop when the speed is put to 0
%. It is also possible for the user to stop the product by disconnecting the mains power, provided
a brake is installed correctly or the gear is dynamic self-locking. After Power interruption the
motor enable channel shall be pullet to 0% and back to the enable range before the product can
function again.
