3.8 FU91/92 Follow-Up Lever
The FU91/92 FU lever has been designed for use primarily together
with the FU9X follow-up amplifier. The construction is made such
that either one single PCB, containing all the electronics, including
the follow up potentiometer or two identical PCB's can be mounted
and operated from one common FU-shaft.
The single version is the FU91, and the double version is the FU92.
The designed is based on "TAKE COMMAND" pulses and "IN
COMMAND" signals that makes it possible to use several units
connected to the FUA9X.
There are four jumper switches for selection of functions, and for use
together with the AP9 MK3 autopilot, the settings are as shown:
S1: Selects direction of signal versus direction of lever movement. Pos
1-4 and 2-3
S2: Pos 1
S3: Pos 2
S4: Pos 1
