We have detected fails in 3 FLD modules installed in the same instrument.
The fist of these gave the error 06712 (emission motor did not find position),and was replaced with a second module. This when it was being installed failed again (EMISSION MOTOR HAS FAILED. EMISSION ENCODER ERROR) a had to be replaced with a third module.
Only one month later the third module was installed, it has failed again. This time the error given has been 06713 Excitation Motor lost its position.
Perhaps, it could be due to the firmware but we are not sure.
Thanks a lot for your help.
