Z650 Feeder card

Hi I am looking for help my problem is the 650 do not start and is showing

in the LOg file as folowing

error 60103 feeder not calibrated

error writing to Zprinter 650 Adaptor eeprom

Ad7730 No reference detected, status byte : Oxff

InitCal: Eeprom calibartionchecksum failed. Datain Eeprom is not valid

I observe that on the Tiamat Feeder Cart ZPN: 50067 the +5 V LED is dark and the ADC RDY Led as well .

Is there somewhere a electric wireing/diagram available.

Thanks a lot for support

Dietmar
