I found the solution:

cooling fan are not broken.

If alarm come on the cooling fan 12 (6/2/12) on IBBU BTS ultrasite, the problem is on the CCUA Q1.

CCUA can be 2 adress: 4085 or 4084.

PSM manager => climatic control => FAN.
the CCUA must see 9 cooling fan with the good Q1 adress.
I don’t know explain but CCUA and BOIA are the same Q1 Bus for the climatic control.

Problem is over.
