Hi Juanse

I'm guessing that your system is 250 volt and all your motors are 250  
volt.  The horizontal extractor(likely north american manufacture) is  
also 250 volt but the control is 120 volt.  Likely the system is  
intended to be grounded at the centre tap providing  120/125 volt for  
the control.  Please don't assume I'm right as the sparks won't fly  
this far.  I worked in Nigeria and Jamaica  where equipment was  
imported from all over the world, during my electrical career but I  
can't troubleshoot safely from this distance.
