B. Crossfeed Valve Actuator 5QE
The crossfeed valve actuator has two electrical motors which drive the same differential gear to turn the ball valve through 90 deg. Limit switches in the actuator control this 90 deg. movement and set the electrical circuit for the next operation. One of the two motors can open/close the valve if the other motor does not operate. A V-band clamp (83QM) attaches the actuator to the flange of the drive assembly. A location peg makes sure the actuator engages correctly.
7. Operation/Control and Indicating________________________________ (Ref. Fig. 002)
A. Operation/Control The crossfeed valve is controlled manually. To operate it is necessary to have: - the 28VDC BUS 2 206PP and the 28VDC ESS.SHED. BUS 801PP energized - the circuit breakers 1QE and 2QE closed. When the X FEED P/BSW (4QE) is pushed (in): - the 28VDC supply energizes the two electrical motors of the actuator - the crossfeed valve turns to the open position - the crossfeed valve signals its position to the ECAM FUEL page display.
When the same P/BSW is released (out): - the 28VDC supply energizes the two electrical-motors of the actuator - the crossfeed valve turns to the closed position - the crossfeed valve signals its position to the ECAM FUEL page display.

The crossfeed valve position is shown on the FUEL page of the ECAM System Display. If a failure occurs in the fuel system the FUEL page is shown on the ECAM System Display. If you want to look at the ECAM FUEL page you must push the FUEL P/BSW on the ECAM control panel. System Failures If the crossfeed valve is not in the set position:
-
the message FUEL X FEED VALVE FAULT is shown on the ECAM Engine/Warning Display Page
-
the crossfeed valve indication is shown amber on the ECAM SD FUEL page.
