Code 5280: “Ambient - Temperature too high”
This error code is probably preceded by the warning code: ambient - temperature high”. The same
troubleshooting table can be applied to.
Code 5281: “Ambient - Temperature high”
Situation Solution
Ambient temperature too high. Check the ambient temperature at the air inlets of the projector. Make sure
that the ambient temperature does not exceed 35°C (95°F).
Blocked dust filter. Clean the large dust filter or replace with new one. See service manual
chapter “Check the large dust filter”, page 284.
Malfunction air extraction
system.
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
3
/min (180 CFM).
Excessive air extraction can dramatically speed-up contamination of the
projector air inlet filters, hence requiring more regular filter cleaning
interventions.
Defect temperature sensor. Replace the ambient temperature sensor (reference 12 Image 25-51).
Malfunction Cinema Control
board.
Replace the Cinema Control board. See service manual chapter
“Replacement of the Cinema Controller”, page 217.

Code 5284: “Ambient - Temperature sensor open”
Situation Solution
Temperature sensor
disconnected.
Check if wire (reference 14 Image 25-52) of the ambient temperature
sensor (NTC) is connected with the Signal Backplane.
Defect temperature sensor. Replace the ambient temperature sensor (reference 12 Image 25-53).
Malfunction Cinema Control
board.
Replace the Cinema Control board. See service manual chapter
“Replacement of the Cinema Controller”, page 217.
Malfunction Signal Backplane. Replace the Signal Backplane. See service manual chapter “Card Cage”,
page 209.
