Lamp will not strike, but there are no fan errors on the Status screen and Ballast is okay
Details: If the lamp does not strike after the command is given, but there are no fan errors on the Status screen
and the Ballast is known-good, it may indicate that the Ignitor PCB has failed.
Procedure: Remove Tilt-Side Yoke Cover to access Ignitor PCB
and engages upon fixture power-up. Verify the polarity of the power input cables to the Igniter and ensure they
are on the correct terminals. Carefully remove lamp from fixture
given, you should read 400 VDC on the input terminals of the Ignitor and a red neon lamp will glow on the PCB.
If the red neon lamp does not glow, then the Ignitor has failed.
Solution: Replace Ignitor PCB...
Wheel Stack and/or Frost (Diffusion) Issues
Status screen is displaying errors for Dimmer, Strobe, Color Wheels, Gobo Wheel, Iris and/or Frost
mechanisms
Details: Upon power-up, all mechanisms in the fixture will execute a calibration routine. Each mechanism must
pass its calibration test or it will disable itself and possibly other mechanisms. The Wheel Stack Assembly con-
tains 12 separate functions that it will test. After calibration, the status of each of these mechanisms, or mech-
anisms controlled outside the Wheel Stack such as the Frost function, will be displayed on the Status screen by
the color of their mechanism name abbreviation or "sub-code." These mechanisms are:
• Dimmer Wheel - DIM
• Strobe - STR
• Cyan Filter Wheel - CYA
• Yellow Filter Wheel - YEL
• Magenta Filter Wheel - MAG
• Designer Filter Wheel - DES
• Gobo Wheel 1 - GO1
• Gobo Wheel 1 Index - IN1
• Gobo Wheel 2 - GO2
• Gobo Wheel 2 Index - IN2
• Beam Size Iris - IRS
• Diffusion (Frost) Paddle - FRO
If the sub-code is green, that particular function on the Wheel Stack has passed the calibration test. If the sub-
code is red, that function did not pass and is disabled. (Refer to
Procedure: Ensure that all Wheel Stack cables are securely connected. Check for blown fuses. On each of the
three Wheel Controller PCB's, there are four (4) motor drivers. There is a 2 Amp Timed (Slo-Blow) Fuse to pro-
tect each of the four drivers. They provide power for both the servo motors and the stepper motors. If during
calibration or operation, you observe a mechanism servo motor or stepper motor that appears to have no
power, locate the Wheel Controller PCB and the driver for that motor. Check the driver and fuse for that motor.
If cables are secure and there are no blown fuses, replace the Wheel Stack Assembly.
CAUTION: There are no field-serviceable parts in the Wheel Stack Assembly. Do not attempt to disassemble
the Wheel Stack Assembly. Replace with a spare assembly in the event of a failure.
Solution: Replace 2A Fuse...
Solution: Replace Wheel Stack Assembly...
