YNCHRONIZATION

)
The Systems default method of synchronization is an Equal Throttle
Synchronization. With this type of synchronization the Processors
ensure that the same or an equal Throttle Command Signals are
applied to both Governors when the synchronization criteria has been
met. Though not true Synchronization, in most cases synchronizing in
this manner is very effective.
If a true synchronization is required or requested, Active Synchroniza-
tion would need to be selected. In addition, Active Synchronization
requires a Tachometer Signal representative of each engines’ RPM’s.
The frequency of these signals are measured and changes to the Throt-
tle Command Signal outputs of the Processors are made until the fre-
quency of both engines are the same and both engines are running at
the same RPM.
The Processors need to be interconnected with a Serial Communica-
tion Wire Harness as demonstrated on the Drawing in Appendix C.
These Harnesses will be plugged on both ends of the cable.
A)Remove the SERIAL plug-in cap from all Processors and dis-
card.
B) Insert the Serial Wire Harness plug into the SERIAL connector
on one of the Processor Covers.
C) Run the harness cable to the next Processor and plug into the
SERIAL connector on the Processor.
