3. Troubleshooting
Situation
Solution
Blocked high density filter of the
heat exchanger. The other DMD
temperatures are too high as well.
Replace the blocked high density filter of the heat exchanger with a new high density
filter.
The liquid cooling circuit of the light
processor is mistakenly excluded
from the main liquid cooling
circuit. Most likely the other DMD
temperatures are too high as well.
Check of the cooling circuit of the light processor is connected with the pump and
heat exchanger.
None of the wire units of the Peltier
elements (TEC) or there respective
temperature sensors (NTC’s)
are connected. The other DMD
temperatures are too high as well.
Check if the wire units of all Peltiers and all temperature sensors (NTC’s) are plugged in
there respective connector sockets on the interface board. See image 3-20.
The wire units of two Peltier
elements (TEC) or there respective
temperature sensors (NTC’s)
have been swapped. While the
temperature of one DMD is too high,
the other will most likely be too low.
Check if the wire units of all Peltiers (TEC) and all temperature sensors (NTC’s) are
plugged in there respective connector sockets on the Formatter Interface Board. See
image 3-20.
Malfunction Fan & Motor Control
board. The LED “+VTEC” on the
Fan & Motor Control board remains
off.
Replace the Fan & Motor Control board.
Malfunction TEC of the involved
DMD. Use the “diode test” of a
multi-meter to check out the TEC.
Polarity doesn’t matter. The TEC is
not OK in case the measured value
is higher then 0,01 volt.
Remove the light processor from its compartment and replace the malfunction TEC.
If problem persist contact Barco for further instructions.
Poor assembly of DMD or P
cooler block.
Reinstall the Peltier.
Error 7981 : “Blue DMD temp low”
This is a warning.
Situation
Solution
The electronics of the light
processor remains off due to a low
DMD temperature.
Turning on the lamp will heat up the light processor and the DMD’s.
Error 7982 : “Green DMD temp high”
This error may be preceded by a warning.
Situation
Solution
Blocked high density filter of the
heat exchanger. The other DMD
temperatures are too high as well.
Replace the blocked high density filter of the heat exchanger with a new high density
filter.
The liquid cooling circuit of the light
processor is mistakenly excluded
from the main liquid cooling
circuit. Most likely the other DMD
temperatures are too high as well.
Check of the cooling circuit of the light processor is connected with the pump and
heat exchanger.
None of the wire units of the Peltier
elements (TEC) or there respective
temperature sensors (NTC’s)
are connected. The other DMD
temperatures are too high as well.
Check if the wire units of all Peltiers and all temperature sensors (NTC’s) are plugged in
there respective connector sockets on the interface board. See image 3-20.
