Problem Solution
Won’t power on • Check the fuse (page 17-220).
• Verify fixture is plugged in to an appropriately-rated power source (power
ratings are shown on
page D-304).
• Check power cord wiring
During certain movements
the fixture motion slows,
missteps or loses position
• If you have loosened or tightened anything in the pan and tilt assemblies,
the stepper motors may be out of alignment. Recalibrate pan and tilt motors
by selecting Calibrate Motors button in the Test_Home menu screen.
Powers on but no image • Is the mechanical iris closed? If so, check the setting for the Dimmer
parameter, (see
“Dimmer” on page 14-179.)
• Did you recently change inputs? About 10 seconds are required for an input
change to take effect. However, you might have selected an invalid input
using projector controls.
Try setting the projector back its defaults, (see “Reset Screen” on page 3-36.
Or use DMX to exit the projector menu system (see “Projector Control” on
page 14-181).
• Make sure a video input is physically attached to the input you selected, and
that the video feed is active.
Image appears “clipped off”
at the bottom
• This occurs when the iris plate is in the wrong position for the installed lens
and lens shift is not engaged. Standard, Accessory Wide Angle and
Accessory Ultra Long Throw lenses use one position. The Accessory Long
Throw lens use another (see
“Adjusting the Iris Plate for the Accessory Long
Zoom lens” on page 17-221).
