Abstract
The present invention provides a method and apparatus for testing a valve control system in an aircraft fuel supply system having a plurality of control valves, wherein the control system includes a processor adapted to receive feedback signals from each of the plurality of control valves, the method comprising the steps of: connecting a test device to the control system such that the test device is connected for signal transmission to the processor; outputting a signal to the processor simulating a feedback signal from at least one of the control valves; detecting a control signal which is output by the processor to the at least one of the control valves; and identifying the detected control signal which is output by the processor to the control valve.
Claims15
A method of testing a valve control system in an aircraft fuel supply system having a plurality of control valves, wherein the control system includes a processor adapted to receive feedback signals from each of the plurality of control valves, wherein each of the plurality of control valves is adapted to be operated independently by two actuator motors and the processor is adapted to receive feedback signals from each actuator motor of the plurality of control valves, the method comprising the steps of:
- connecting a test device to the control system such that the test device is connected for signal transmission to the processor;
- the test device outputting a signal to the processor simulating a feedback signal from at least one of the control valves;
- detecting a control signal which is output by the processor to the at least one of the control valves;
- and
- identifying the detected control signal which is output by the processor to the control valve,
- wherein the step of outputting a signal to the processor includes outputting a signal simulating a feedback signal from one of the independent actuator motors, to assess the processor's ability to recognize the individual state of each of the independent actuator motors.
An apparatus for testing a valve control system in an aircraft fuel supply system having a plurality of control valves, wherein the control system includes a processor adapted to receive feedback signals from each of the plurality of control valves, wherein each of the plurality of control valves is adapted to be operated by two independent actuator motors and the processor is adapted to receive feedback signals from each actuator motor of the plurality of control valves, the apparatus comprising:
- connector means for connection to the control system such that the apparatus is adapted for signal communication with the processor,
- signal means adapted to output a signal to the processor simulating a feedback signal from one or more of the plurality of control valves;
- detector means for detecting a control signal which is output by the processor to that one or more of the plurality of control valves;
- and
- indicator means for identifying the detected control signal output by the processor to the control valve,
- wherein the signal means is adapted to output a signal to the processor simulating a feedback signal from one of the independent actuator motors, to assess the processor's ability to recognize the individual state of each of the independent actuator motors.
