The projector used to have a heat filter in front of the douser. Last year it fell off and our tech assured the manager that this was no problem, so the machine now runs for about a year without heat filter. There have been no problems until last week, when this heat issue started. I must add that about a month ago, a new bulb was fitted (not by me). For tree weeks after that, there were no problems. This afternoon, i talked to the tech (who is on holiday at the moment ), and now he wants me to put the heat filter back in. Never done such a thing but i have to try, there's no backup so i'm pretty much on my own. Yesterday i already lowered the current by about 5 A an it didn't really help. The problem is that crappy, uncalibrated current meter on the lamphouse: it tells nothing, so i don't know what i'm doing and i hate that. I now have a current measuring device to put over a cable (don't know the English word) but i have no idea on what cable i should measure. It should carry a one-way current according to the manual. Any suggestions?
The gate is not water cooled, and air intake is working (new air filter last week, so that shouldn't be a problem).
Thanks, Rob
