Code 6062: "+24v - voltage too low" (Error)
This error code is probably preceded by the warning code 6063: "+24v - voltage low". The same troubleshooting table can be
applied.
Code 6063: "+24v - voltage low" (Warning)
Situation
Malfunction Fan Control board or
SMPS board.
Short circuit or bad connection.

Situation
Malfunction Fan Control board or
SMPS board.

Solution
Measure on the Signal Backplane the +24V voltage on pin 9, 10, 11 or 12 of the
connector of the black wire unit which comes from the SMPS board. See image 4-43.
If the measured voltage is about 24V then replace the Fan Control board. See
"Removing a board in the card cage", page 213. Otherwise replace the SMPS board.
See"Replacement of the Switched Mode Power Supply", page 281.

Solution
Measure on the Signal Backplane the +24V voltage on pin 9, 10, 11 or 12 of the
connector of the black wire unit which comes from the SMPS board. See image 4-43.
If the measured voltage is about 24V then replace the Fan Control board. See
"Removing a board in the card cage", page 213. Otherwise replace the SMPS board.
See"Replacement of the Switched Mode Power Supply", page 281.
1. Check the Signal Backplane for bad connections. Ensure that all wire units are
well connected.
(Note that the +24V supply is generated on the SMPS board and enters the Fan
Control board and Cinema Control board via the Signal Backplane)
2. Check the wiring of the Anode fan for short circuits.
3. Check the wiring of the Cathode fan for short circuits.
Solution
Measure on the Signal Backplane the ++12V voltage on pin 1, 2 or 3 of the connector of
the black wire unit which comes from the SMPS board. See image 4-43.
If the measured voltage is about12V then replace the Fan Control board. See
"Removing a board in the card cage", page 213. Otherwise replace the SMPS board.
