Hi,
I've just bought a Durst 1200 with cls 450 head, unfortunately without power supply. I've built one for it, its output is 24V AC, 250VA. Light is OK, but the cooling fan is not working. There are two wires for the bulb, another for connect the head to ground and three more thinner wires which I'm not sure about. I think one of them is for filter's check light the rest are for cooling fan.
My questions:
- does the fan have a heat switch or it is always on?
- is there anybody who has an original power supply and would measure for me the voltage of each wire?
- maybe somebody has circuit diagram for it?

Thanks in advance.
