DMX controller operation 51

Lamp

Lamp on

With the default setting, the lamp remains off until a “lamp on” command is

sent from the controller. To have the lamp strike automatically within 90

seconds of powering on, activate the Automatic Lamp On personality (see

“Fixture settings” on page 21).

A large peak of electric current is drawn for an instant when striking a

discharge lamp. Striking many lamps at once may cause a voltage drop

large enough to prevent lamps from striking and/or trip circuit breakers.

When striking multiple lamps, program a sequence that strikes lamps one at

a time at 5 second intervals. If Automatic Lamp On is enabled, there is a

delay of up to 90 seconds that is determined by the fixture address.

Lamp off

The lamp can be turned off from the controller by sending a “lamp off”

command on channel 1. If the DMX Lamp Off personality is off (see “DMX

lamp off option” on page 47), the command only works if each of the CMY

channels (3, 4, and 5) is set to a DMX value from 230 to 232.

After being turned off, the lamp must cool for at least 8 minutes before it can

be turned back on. “Lamp on” commands sent within 8 minutes of a “lamp

off” command are stored and then executed after the time has elapsed.

Color

Color wheel

The color wheel has red, green, and blue dichroic color filters plus a 5600K

to 3400K color correction filter and open white. It may be used together with

CMY color mixing to increase color saturation. The wheel scrolls

continuously, allowing for split-color effects, or in full steps. It also rotates

continuously in both directions at different speeds.

Setting the color speed to “blackout” in mode 2 causes the shutter to black

out the light while the wheel moves.

CMY subtractive color mixing

The CMY color mixing system is based on graduated cyan, magenta, and

yellow color filters. A continuous range of mixed colors may be achieved by

1 2 ... 46 47 48 49 50 51 52 53 54 55 56 ... 83 84
