Cooling & chillers
Part of Dome troubleshooting — start there for quick triage. The six XDL projectors each have a separate chiller, frequently in a different room from the projector it serves — see the position table on the overview. A projector fault may actually be a chiller fault one floor away, so identify the pairing before moving.
The causes and step sequences on this page are informed reconstructions pending review — see the note on the main troubleshooting page.
Chiller alarm or projector overheating
- Identify which chiller serves the alarming projector. Getting this wrong sends you to the wrong floor.
- Check the chiller for alarms, flow and coolant level.
- Check the chiller's power feed on PDUs.
- Do not keep restarting a projector that is thermally alarming. Escalate.
