Note: Executing a "Reset Fixture to Defaults" does not change the last iris selection setting.
• To select and set iris type via control channel.

Zoom Assembly Operation - Edge Tracking

This feature allows for the edge to retain focus during zoom operation. To utilize this feature, enable
EDGE TRACKING using the control channel. Set your individual edge settings as desired. Then
operate the zoom. The edge should now track focus more consistently. Note that the edge mechanism
does move during these adjustments. However, if you have written focus (edge) cues with the edge
tracking disabled, the units will focus differently once you enable edge tracking. You must enable the
tracking any time you wish to use it.
Note: For previously cued shows, you will want to DISABLE edge tracking, which is the default.

Dimmer Operation - Dimmer Snap

By enabling DIMMER SNAP, using the control channel, you allow the dimmer wheel to take the
shortest path during a zero-time move.
• From 0% to 1 thru 50%, the wheel moves in one direction (shortest path to desired value).
• From 0% to 51 thru 100%, the wheel moves in the other direction (shortest path to desired value).
There is also a delay added into the dimmer wheel with DIMMER SNAP enabled. If you cycle back
and forth between 0 and 100% in zero time, what you will notice is that ONLY the strobe blades will
open and close. The dimmer wheel will always remain in the 100% position. They will only close if
you remain at 0% for MORE than 2 seconds.
Note: If you change the intensity value, say from 100% to 80% before the 2-second delay has
occurred, the dimmer wheel will NOT change position. It will remain at 100%. You have to hold either
value for more than 2 seconds for the dimmer wheel to move.
