Effects

This section describes DMX-controllable effects that require particular

explanation. See DMX protocol on page 26 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 15.

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 31).

Dimming

Full range mechanical dimming is provided.

Strobe effects

A range of variable strobe and pulse effects are available, with variable speed and

random effects.
