The engine control system supplies manual and automatic control inputs to operate the engine. The engine control system has these components:
1·Thrust levers (forward and reverse)
2·Thrust lever resolvers
3·Engine start levers and switches
4·Thrust lever interlock solenoids.

   Thrust Levers
You use the thrust levers to supply the manual inputs to the engine control system. There are two thrust lever assemblies, one for each engine. For each engine, there is a forward thrust lever and a reverse thrust lever. The reverse thrust lever is on the forward thrust lever.
For each engine, the thrust levers supply a thrust command signal to the electronic engine control (EEC) through the thrust lever resolver. Each thrust lever assembly connects mechanically to the resolver through an adjustable rod.
An interlock latch prevents the operation of the forward thrust lever and the reverse thrust lever at the same time.

Thrust Lever Resolver
There are two thrust lever resolver assemblies, one for each engine. Each thrust lever resolver assembly has two resolvers, one for EEC channel A and one for EEC channel B. The thrust lever resolvers change the mechanical forward and reverse thrust lever positions to analog thrust lever resolver angle (TRA) signals. These signals go to the EEC. The EEC uses these signals to control the engine.

   Start Levers
There are two start levers, one for each engine. You use the engine start lever during an engine start. You also use it to shutdown the engine. The start levers operate switches which supply signals to different aircraft and engine systems and components.

Reverse Thrust Interlock Solenoids
There are two reverse thrust interlock solenoids, one for each engine. Each reverse thrust interlock solenoid limits the range of motion of a reverse thrust lever. You can make the thrust reverser deploy, but you can not increase the reverse thrust until the thrust reverser sleeves are near the full deployed position. The EEC operates the solenoids. The thrust lever interlock solenoids are in the autothrottle assembly. You must lower the autothrottle assembly to access the thrust lever interlock solenoids.
                                                                        选自--SDS手册
