Light processor fan
Code 5461: “lamp anode fan - voltage high” (Warning)
Situation Solution
Malfunction Fan Control board or
SMPS board.
Measure on the Signal Backplane the +24V voltage on pin 9, 10, 11 or 12 of the
connector of the black wire unit which com es from the SMP S board. Se e im age 4-26.
If the measured voltage is about 24V then replace the Fan Control board. See
"Removing a board in the card cage", page 213. O therwise replace the SMP S board.
See"Replacement of the S witched M ode Power Sup ply", page 281.
Code 5462: “lamp anode fan - voltage too low” (Error)
This error code is probably proceeded by the warning code 5463: “lamp anode fan - voltage low”. The same troubleshooting table
can be applied.
Code 5463: “lamp anode fan - voltage low” (Wa rning)
Situation Solution
Malfunction SM PS module. A ll other
fans also report voltage low error.
Replace the SMPS module. See "Replacement of the Switched Mode Power Supply",
page 281.
Damaged insulation of the wire unit
(reference 2 image 4-29) of the
Anode fan (reference 1 image 4-29).
Check the insulation of the wire unit of the Anode fan. The Anode fan is located below
the com partment of the Light Processor.
1. Repair the insulation of the wire unit using shrink sleeve.
2. If not repairable replace the Anode fan. See "Lamp anode fan", page 324.
Malfunction Fan & Motor Control
board.
Replace the F an & Motor C ontrol board. See "Removing a b oard in the card cage",
page 213
Malfunction Signal Backplane (bad
connection)
Replace the Signal Backplane. See "Replacement of th e s ignal back plane", page 231.
