Transformer Problem Xl/xls

[Brainwave]

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

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.

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 ?
