I send back the new Geo brick to fix,was burned at the 24 vdc input,since this; we found a short circuit in one sensor,that was the reason of the AF1 fault, into the manual of the unit explains over frequency , this cuould be due affects the DC link of the inverters.
The root cause of all this problem was the design of the machine power supply to the Geo brick and miscellaneos.
The Geo brick and all the I/O¨s shares the same 24 vdc, if something goes wrong on the i/o´s this hits the Geobrick.
I will install some kind of opto22 and an exclusive 24 vdc power supply only for the Geo brick.
Thank you guys for the support ,Richard,Stephen. Was a funny week.
