processes the input from each LVDT.
EEC
The EEC changes the LVDT analog signal to a digital signal.
The EEC and DEUs contain the REV message indication logic.
The EEC sends a signal on an ARINC 429 bus to each display
electronics unit (DEU). The DEUs show the REV message on the
common display system (CDS).
Channel A and channel B calculate sleeve position from the
LVDT input. The EEC usually uses an average of the two values
in its logic to show the message.
The EEC also has the LVDT failure logic. When conditions are
met, the amber ENGINE CONTROL light and master caution
come on.

General
You use the control display units (CDUs) to do trouble-shooting
of the linear variable differential transformer (LVDT). The CDU
shows real time data or failure codes.
See the engine indicating chapter for more information about
other engine maintenance messages that the CDU shows.
(CHAPTER 77)
Failure Data
The EEC records a LVDT failure when any of these happen for
more than 5 seconds:
* LVDT input to EEC is out of range
* EEC channel A and B see that sleeve is 10 percent to the
deploy position and forward thrust levers are forward of the
idle position.
* The value of the difference between the T/R sleeve’s position
signals on EEC channel A and B is greater than 12 percent.
Real Time Data
You use the CDU to see this real time data for any LVDT:
* Sleeve position in percent travel to deploy position (usually
average of channel A and channel B)
* Sleeve position in percent travel to the deploy position for
the EEC channel you select
* EEC channel A and B LVDT voltage data.
