056357/B RAC
5-2 Electrical Installation
Rudder Angle Feedback Unit Potentiometer
Generally, a dedicated rudder angle feedback unit will be installed for
the RAC. Alternatively, one or more RACs may use a separate
potentiometer in a feedback unit which also contains potentiometers
for, e. g., other RAI systems or the VDR.
WARNING
Risk of injury
Connecting the Rudder Angle Calibrator to a rudder angle feedback unit
in parallel with the steering gear feedback loop bears the risk of malfunc-
tion of the steering gear in case of wire breaks or short-circuits resulting
in possible injury and/or damage.
Under no circumstances must the RAC be connected to a rudder angle
feedback unit potentiometer in parallel with the steering gear feedback
loop.
CAUTION
A
Risk of damage
As the feedback potentiometer supply voltage is provided by the Rudder
Angle Calibrator, connecting the RAC to a feedback potentiometer in par-
allel to any device other than a second RAC bears the risk of damage in
case of wire breaks or short-circuits.
Never connect the RAC to a feedback potentiometer in parallel to any
device other than a second RAC.
