YNCHRONIZATION

The CruiseCommand System utilizes dual lever synchronization. Dual
lever synchronization provides the security of both of the Control
Head levers always being active.
Synchronization is automatic and only operates in Ahead; conse-
quently it can be left ON full time. Cruise-Command will always
power-up with synchronization Enabled.
In order for synchronization to become active and work toward syn-
chronizing the engine’s RPM’s, the Control Head levers must be in the
synchronization range.
Synchronization Range is :
• Both Control Head levers are in an Ahead position
• Greater than 5% percent of the throttle range is commanded
• Commanded throttles must be within 10% of one another.
The Processor’s throttle signals are compared and then matched. The
Processors then send the same signal to all engines. The engines are
now synchronized.
A green LED indicator light located on the Control Head of the Sta-
tion-in-Command indicates engine synchronization:
• When the green LED is NOT LIT, no synchronization.
• When the green LED is LIT, synchronization.
Synchronization can be turned OFF and ON:
To turn synchronization OFF:
1. Place the Control Head levers in the synchronization range .
2. Push the Transfer Button until the green LED blinks and goes out (approxi-
mately 2 seconds). Synchronization is now OFF.
To turn synchronization ON:
1. Place the Control Head levers in the synchronization range .
2. Push the Transfer Button until the green LED lights (approximately 2 seconds)
• The green LED light will blink as the system is working to synchronize.
• The green LED will become solid green when the engines are synchronized.
