Error 7690 : “Green front DMD temp high
”
This error may be preceded by a warning. This error can only appear on the FLM HD series.
Situation Solution
The wire unit of the temperature
sensor at the front of the DMD is
mistakenly switched with one of the
wire units of the other temperature
sensors of the light processor.
Check if all wire units of the temperature sensors are plugged into their respective
sockets on the Formatter Interface Board. See image 3-11.
The wire units of the TEC’s (Peltier
element), mounted on the common
cooling block of the heat pipes, are
mistakenly switched.
Check if all wire units of the TEC’s are plugged into their respective sockets on the
Formatter Interface Board. See image 3-11.
No thermal contact between heat
pipes of the involved channel and
common cooling block due to loose
screws.
Check if the four screws, which attach the heat pipes to the common cooling block,
are fastened. See image 3-18.
Malfunction TEC between heat
pipes and common cooling block.
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.
