Code 5975: “dmdred front - temperature sensor short” (Error)

Situation

Solution

Damaged insulation of the wire unit of the temperature sensor(reference S3 Location temperature sensors and Peltier element per channel.) which measuresthe temperature at the front side of the DMD of the red channel. Whendisconnecting the wire unit (reference FR/R ) of the temperature sensor from the FormattingInterface Board the error code is changed to “dmd red front- temperature sensor open”.

  1. Repair the insulation of the wire unit using shrink sleeve

  2. If not repairable, replace the whole Light Processor Unit. ContactBarco for further instructions to repair the malfunction light processor.

Defect temperature sensor which measures the temperature atthe front side of the DMD of the red channel.

Replace the whole Light Processor Unit. Contact Barco for furtherinstructions to repair the malfunction light processor.
