Effects
This section describes DMX-controllable effects that require particular
explanation. See ‘DMX protocol’ on page 33 for a full list of the DMX channels
and values required to control the different effects.
Lamp control
For maximum lamp operating life:
•
Avoid powering the lamp off until it has warmed up for at least 5 minutes.
•
Before shutting down power completely, douse the lamp but leave power
applied for a few minutes so that cooling fans can prevent any momentary
lamp temperature increase caused by heat from surrounding components.
The fixture can be set to automatically turn the lamp on or off depending on
whether or not a DMX signal is present.
The fixture can also be set to respond to or ignore lamp off commands sent
via DMX.
An ignition delay of 0 to 255 seconds can be set, so that there is a delay
between power on and lamp on.
A low-power delay of 0 to 255 seconds can be set, so that when a lamp off
command is sent the lamp runs at half power for a user-defined period before
shutting down.
For more information, see ‘Lamp settings’ on page 18.
Pan and tilt
The fixture’s moving head can be panned through 540° and tilted through
270° using coarse or fine control channels. The fixture can be set to
automatically blackout during pan and tilt movement.
The fixture incorporates pan and tilt feedback, so that if a pan or tilt position
error is detected, the shutter closes and the fixture resets to the correct
position. This can be enabled or disabled as required (see ‘Control menus’ on
page 38).
Dimming
Full range mechanical dimming is provided.
