Powering Up
Power-Up Procedure
Since Lamp On is the default state, the lamp will strike when the luminaire is powered up for the first
time. When AC power is applied, the luminaire will immediately begin a calibration sequence that
steps it through full pan and tilt movements. The internal color, gobo, and beam mechanisms will also
move through a full range of motion. After calibration, the luminaire head will either stop 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 move to its current DMX-defined position if
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
Functions” on page 53), 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.
To power up:
Step 1. 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.
