Brainwave Posted December 13, 2007 Report Share Posted December 13, 2007 The transformer of my zero 88 Xl light desk is broken. Does anybody know the voltages to te mainboard ? The things i kwow are : Transformer 22 VA 4347 INPUT ==> Blue = N / Yellow = 110 V / Red = 220 V OUTPUT ==> 12 V for the desklight / Red = ? / Blue = ? / Green = ? / Yellow = ? / Orange = ? Or if somebody have the schematics of the main circiut board Greatz Quote Link to comment Share on other sites More sharing options...
Paul Posted December 13, 2007 Report Share Posted December 13, 2007 The transformer used in early XL's was: 5521000 Transformer 11+17v 22VA was: 4347 B2554, 0-120-240, 17.5-10.5-0 This later changed to: 5525000 Transformer 11 + 17v 22VA B2749 22VA (Prim. 240/117/0, Sec. 17.7/11.0/0 & 11.0/17.7 & 0/11.5) Sounds like you have the first version. Unfortunately we can't get either of these transformers any more. The connector on the PCB goes 17-11-0-11-17, not sure which transformer wire colours that relates to though. Hope this helps, Paul.

Brainwave Posted December 18, 2007 Author Report Share Posted December 18, 2007 I have installed a new transformer with the 17-11-0-11-17 V to the main-PCB result = Nothing Is there somebody who have the circuit of the mainboard ? Or have/know the same problem ? GRZ Quote Link to comment Share on other sites More sharing options...
