Zoom Tables
The zoom tables, which allow the fixture to maintain sharp focus on an image throughout the zoom range, are
sensitive to the throw distance. For this reason, a variety of zoom table versions are available for use with different
throws. The zoom table is selectable via control channel settings described in
"Control Channels" on page 45. The
zoom table setting is persistent and will maintain its value through power cycles. The default setting is 30 feet.
Gobo Set Zero Position
The Gobo Set Zero command allows adjustment of the gobo wheel’s home position. When this command is issued,
the luminaire sets the current wheel position as the "zero" position and stores this offset so it will be retained at the
next startup. This allows correction for a sensor that may be slightly out of position causing the gobo wheel to not be
perfectly centered and therefore obstructing part of the beam in the open position.
To set zero position:
Step 1. Using console, move wheel into desired center position.
Step 2. Execute Set Zero Position command (Control Channel DMX value 80). The luminaire will now remember the
setting as the new zero position.
