Code 5343: "dmd red - temperature low" (Warning)
Situation
The electronics of the Light
Processor remains off due to a
low DMD temperature.
Defect temperature sensor.
Solution
Clean the large dust filter or replace with new one. See service manual
chapter "Check the large dust filter", page 284.
Clean the small dust filter or replace with new one. See service manual
chapter "Check the small dust filter", page 285.
Check the ambient temperature at the air inlets of the projector. Make sure
that the ambient temperature does not exceed 35°C (95°F).
Check the condition of the air extraction system. The air extraction system
must be capable of removing minimum 4 m³/min (140 CFM) per installed
DP2K-SLP Series digital projector.
Note: limit the amount of extraction to a maximum of 5m
Excessive air extraction can dramatically speed-up contamination of the
projector air inlet filters, hence requiring more regular filter cleaning
interventions.
Replace the temperature sensor (reference 18 Image 25-60) which
measures the heat sink temperature of the DMD of the red channel.
Replace the Cinema Control board. See service manual chapter
"Replacement of the Cinema Controller", page 217.
Replace the whole Light Processor Unit. See service manual chapter
"Light Processor replacement process", page 97. Contact Barco for further
instructions to repair the malfunction Light Processor Unit.

Solution
Make sure that the ambient temperature is within specs (higher then 10°
C (50°F)). Let the projector acclimate. Do not ignite the lamp, otherwise
there is a risk for condensation.
Replace the temperature sensor (reference 18 Image 25-60) which
measures the heat sink temperature of the red channel.
