_ DEC-O-LOG for BA60 _ DOL, BA60-F001, RM VAX 6000 airflow sensors trip FEB 94 APPLICABILITY: This "F" coded FCO should be installed on RM VAX 6000 systems ONLY and ONLY WHEN FAILURES ARE MANIFESTED. If breaker trips on power-down, the field engineer should replace airflow sensor P/N 12-34926-01 with new part P/N 12-36060-01. PROBLEM & SYMPTOM: The Airflow sensors are nuisance tripping, meaning old assembly (P/N 12-34926-01) detects loss of 12VDC power causing AC circuit breaker to trip during power-down. SOLUTION: Install FCO ONLY & ONLY if prob lem exists! Replace airflow sensor P/N 12-34926-01 as per procedure with a new sensor P/N 12-36060-01. *** CAUTION *** The Rework procedure MUST be followed when you install the airflow sensor. The sensor window MUST be perpendicular with the air stream (see rework procedure). QUICK CHECK: Verify the new part number (P/N 12-36060-01) for airflow sensor.
