Operation
With the SYNCHROPHASE switch selected to ON, the system is powered, indicated by the
advisory light which comes on.
Input signals from the pulse generator are processed by the synchrophase control box.
Circuits using the signal from engine No. 1 propeller pulse generator as the reference or
master signal relay a correction signal, as required to the torque motor of engine No. 2 PCU.
The torque motor operates through the PCU governor to synchronize the propellers. For
details of PCU operation, refer to the Propeller Maintenance Manual.
