Powering Up
Power Up and Configuration Procedure
Because Lamp On is the default state, the lamp strikes when the luminaire is powered up for the first
time. When AC power is applied, the luminaire immediately begins a calibration sequence that steps it
through pan and tilt movements. The internal color and beam mechanisms also move through a full
range of motion. After calibration, the luminaire head either stops at its “home” position (which
positions the pan axis at mid-rotation and the head parallel to the yoke with the lens pointing away
from the luminaire upper enclosure) or it moves to its current DMX-defined position when DMX data
is present. All internal mechanisms also move to their “home” or DMX-defined positions.
Subsequently, depending on the luminaire’s setting for Lamp Power-Up State (refer to “Menu System
Function Chart” on page 45 ), when power is applied, the arc lamp will either a) “strike” or ignite -
Lamp On ( default) , b) await calibration and then strike - Cal On, or c) await manual command to strike
- Lamp Off.
CAUTION: Before applying power, be sure the luminaire is hung or positioned so that the head and
yoke can move freely without restriction.
WARNING: The light beam projects intense heat. Objects within 3.5 m (11.5 feet) can be damaged
by the beam. Observe the power-up sequence to ensure that the beam does not illuminate objects
within this range. See
“Warnings and Cautions” on page 11 .
To power up:
• At each luminaire, apply power by switching power switch to "
I
" (ON) position. Luminaire will
automatically step through following procedure:
a. If Lamp Power-Up State is set to Lamp On, lamp will strike (ignite).
b. Luminaire will cycle through calibration and stop at "home" position.
c. If Lamp Power-Up State is set to Cal On, lamp will strike (ignite) at end of calibration
sequence.
