System Overview
This dual engine electronic control system consists of the following helm equipment:
•Two Yanmar i5601E Digital Displays (one, if single engine)
•Dual Shift & Throttle Control Head (single shift & throttle control head, if single engine)
Yanmar i5601E Digital Display
The i5601E displays real-time data as well as warnings or alarms for any engine abnormality. Diagnostic codes
will be stored for future reference by a Yanmar technician.
Shift & Throttle Control Head
The Shift & Throttle Control Head selects the gear positions and the throttle settings. The Control Head has
several lights that conrm modes of operation and display warnings, if present. Buttons enable engine RPM
synchronization and shift disconnect as well as setting the brightness of the lights.
Other control congurations with the same functions but different form factors may be used. Refer to the
supplemental material included with those controls.
Helm Components
Although the scope of this document relates to both single and dual engines, the instructions within depict
the more widely used dual engine conguration.
Note: Displays “Single”
if single engine
conguration.

Start Up
WARNING
In normal operating mode, the engine is started and stopped with either the key switch, or the OFF-
ON-START rocker switch.
In an emergency situation, you can use the Emergency Stop switch to kill all power to the engine. This
will allow you to stop at once.
Place the control levers in neutral and turn the PORT ignition switch to the On position – but do not start the
engine. The green control head light will illuminate.
Check to see if the green light on the control head is solid or ashing. If solid, proceed to the next step. If
ashing, push the Select button to select the head. Position the control lever to neutral and the yellow light will
now come on.
Redundant (Back-up) Throttle
In the unlikely event that the throttle signal is lost between the helm mounted shift/throttle control head and the
engine, the system is designed to revert to the redundant or back-up throttle. First, the engine would reduce rpms
to idle speed, the digital display would show “Throttle Error,” and a small red indicator light would ash at the
key panel (or switch panel). Near the red light is a small potentiometer (looks like a volume control knob). Turn
the knob ALL the way to counter-clockwise in order to take control of the throttle. Then turn the knob SLOWLY
to clockwise - the light will glow solid. You will have control of the throttle, however, you will NOT have shift
control. When the signal loss problem has been corrected, you must shut the engine off and restart to return
throttle control back to the shift/throttle control head.
For Emergency Shift see transmission manual.
WARNING
Completely review the start-up procedures on pages 3 through 6 before starting the engine.

In the unlikely event that an engine fault occurs, a warning box appears in the
display showing the cause of the fault, and the action to take, "Press Any Key
To Continue."
These screens show all of the key engine data and can be accessed by pushing a single button. The right-most
button allows the contrast and brightness to be set (see illustration below).
Start Up
i5601E Digital Display
When powered-up, the i5601E Digital Display will initially display an introductory screen showing the software
revision level. It will then display one of the following four screens:

Operation Manual for SY Series Engines with GEN III Controls
Pressing any key acknowledges the alarm and immediately switches the display to the Alarms screen. The
i5601E continues to beep until all alarm conditions (engine faults) have cleared. Unacknowledged alarms are
shown as ashing boxes. Press any key to acknowledge alarm boxes that may still be ashing, and they will then
change to a steady highlighted state.
Start Up
Engine Diagnostic Code Summary Screen
The i5601E is an extremely versatile display. The four-left keys can be recongured to allow the user to display
whatever screens he or she desires. For additional operational details, refer to the Appendix A.
Alarm blocks remain highlighted as long as the alarm condition (engine fault) remains and will automatically
reset to an un-highlighted state after the alarm condition has passed.

Operation Manual for SY Series Engines with GEN III Controls
Various features of the electronic control system have been selected and set as part of the installation. They can
be checked in Appendix C. They include:
• Max Throttle Amount in Split Range Throttle (SRT)
• Shift Delays
• Type of Sync (Power Train or Cruise)
•Station Protection
1. Before starting the engines for the rst time, take a moment to familiarize yourself with the shift and throttle
controls. With the engines not running, move the control levers over the full range until you are familiar with
the feel. Note that the detent pressure and drag can be adjusted using the adjusting screw on the front surface
of the control head. The top screw sets the detent pressure; the lower screw sets the drag.
2. Place the control levers in neutral and turn the ignition switches to the ON position -- but do not start the
engine. The green control head light will illuminate.
a. Check to see if the green light on the control head is solid or ashing. If solid, proceed to the next step.
If ashing, push the Select button to select the head. Position the control lever to neutral and the yellow
light will now come on.
The Shift & Throttle Control Head selects the gear positions and the throttle settings. The Control Head has
several lights that conrm modes of operation and display warnings, if present. Buttons enable engine RPM
synchronization and shift disconnect as well as setting the brightness of the lights.
Other control congurations with the same functions but different form factors may be used. Refer to the
supplemental material included with those controls.
Shift & Throttle Control Head Functions
The most common Shift and Throttle Control Head comes with a dual function, single lever control. A single
lever control initiates both shifting and throttle for a single engine.

Shift Disconnect (SD):
Flashing yellow N (Neutral) lamp indicates SD engaged for this
engine. Allows throttle control without gear engagement.
TO ENGAGE Shift Disconnect:
• Move engine’s lever to the “Neutral” position.
• Press the N (Neutral) button next to this lever. (Yellow lamp
ashes.)
To Disengage Shift Disconnect:
• Return engine’s lever to the “Neutral” position.
• Press N (Neutral) button next to this lever. The yellow
N (Neutral) lamp will go steady - SD is disengaged and
the engine and transmission will now respond to lever
commands.
NOTE: The ashing yellow N (Neutral) lamp can indicate status of either Shift Disconnect (SD) or Split
Range Throttle (SRT). Please exercise caution when engaging/disengaging either of these modes! A steady-on
Neutral lamp ALWAYS indicates engine is in NEUTRAL.
Split Range Throttle (SRT):
Flashing yellow N (Neutral) lamp - SRT engaged for this
engine. Provides greater throttle sensitivity: moving an
engine’s control lever to “Full Forward” will only produce the
maximum percentage of WOT (Wide Open Throttle selected
at set-up - default Throttle Limit is 25%)
TO ENGAGE Split Range Throttle:
• Move engine’s lever to Forward Idle position.
• Press N (Neutral) button next to this lever. (Yellow lamp
ashes.)
TO DISENGAGE Split Range Throttle:
