RESETTING the TRU
In the event that one TRU light comes on the EOP calls for RESETTING the failed TRU once. Resetting to my understanding is selecting the TRU pushbutton OFF and then ON again after several seconds.
I had just been told by an electronics engineer that RESETTING the TRU needs to be done with the BUS TIE to OFF. I do not see this procedure anywhere in the manuals. Anyone here following the BUS TIE off technique?
