changes RPM (hunts).
Will not synchronize
properly
a. A Control Head’s Command Signal is
varying.
a. Scroll to the Diagnostic Menu Function
Code H0. Go to the appropriate Station
A/D Count’s display. The Value should
not change by more than +/- 1 A/D Count.
If so, check the connections and if good,
replace the Control Head.
b. The push-pull cable’s travel from Idle to
Full is too short.
b. Lengthen the Governor or Carburetor’s
selector lever and attach the push-pull
cable to a point where the travel is in
excess of 2.00 inches (50,8mm).
3. Will not
synchronize.
a. Excessive bends in the push-pull cable(s). a. Reroute the push-pull cable(s) or install
Tach Sender and enable Active Synchro-
nization with Function Code E7.

Symptom Causes Solutions
1. Will not
synchronize.
a. The Processor(s) think Astern is being
commanded.
a. Place both the Port and Starboard Proces-
sors into Warm-up Mode by pressing the
transfer button while moving the Control

System Causes Solutions
1. The green LED is lit
solid, though the Engine
RPM’s differ by a signif-
icant amount.
a. The Tach Sender signal has been lost by
one or both Processors.
a. Scroll to Function Code H0. Go to the
Value for the Tach Sender’s input fre-
quency. If the frequency displayed is 0000,
the signal has been lost and the system
diverted to Equal Throttle Synch. Correct
the wiring or replace the Sender.

Control Head levers to more than 5% of the
speed range. Press and hold the transfer
button for 5 seconds.
If synch is disabled, the green LED will
light as long as the button is pressed.
If synch was enabled, the green LED would
have blinked twice.
b. The Serial Communication Harness is not
plugged into both Processors.
b. Plug the Serial Communication Harness
into both Processors.
c. The Port and Starboard Processors have
the same ID number.
c. On the Port Processor, scroll to Function
Code A0 and enter a Value of 01.
On the Starboard Processor, scroll to Func-
tion Code A0 and enter a Value of 02.
D. The Port and Starboard Processors are not
set up for twin screw operation.
