Single Lever Throttle
SYSTEM DESCRIPTION
The throttle is an electro-mechanical system;
an electrical signal is sent from the throttle
lever to the engine ECU to control RPM, and
to an actuator that mechanically operates
the bucket. The system is powered up
upon turning on the ignition key. It is security
interlocked with the engine ECU so that the
engine RPM can only increase above idle
once the bucket is in the correct position.
All bucket movements are directly connected
to movement of the lever.
•
From NEUTRAL push the lever forward to
the detent (+16°), engine RPM will remain
at idle, the actuator will raise the bucket, the
vessel will start to move forward.
•
From forward detent to full throttle (+16°
to +50°), engine RPM will increase from idle
to maximum, the bucket will remain in the up
position, boat speed will increase.
•
From NEUTRAL pull the lever backward
to the detent (-16°), engine RPM will remain
at idle, the actuator will lower the bucket, the
vessel will start to move in reverse.
•
From backward detent to full throttle (-16°
to -50°), engine RPM will increase from idle to
a set limit, the bucket will remain in the down
position, boat speed will increase.
CAUTION. The system will remain
live for a few seconds after the ignition
key is turned off. Ensure no one approaches
either the actuator or the bucket until the
system has completely powered off.
NEUTRAL FINE TUNING
The vessel is supplied with a factory default
for bucket Neutral position. Fine tuning of the
Neutral position is achieved with the position
adjustment buttons. The adjustment has five
steps of 3mm (0.118") each, in both Forward
(+) and Reverse (-). The centre Reset button
returns the system to the factory default
position.
IMPORTANT! Fine tuning is only available
with the lever in Neutral position. Pressing the
buttons when the lever is not in the neutral
position will be ignored by the system.
IMPORTANT! The factory default position is
saved in the system memory. Shutting down
the system power via the vessel ignition key
will reset to the default.
SYSTEM FAULT CODES
The system supports NMEA 2000
Transmission Fault and NMEA 2000 Gear
Engaged.
The system will display a single standard fault
message: "Check Transmission"
Faults causing this message are divided in to
two categories:
Non-blocking faults:
•
Small over current.
•
Small over temperature.
•
Small over voltage.
•
Absence of RPM feedback signal.
•
Internal circuits – small error(s).
•
DC motor speed sensor error.
Blocking faults:
•
Large over current.
•
Large over temperature.
•
Large over voltage.
•
Large under voltage.
•
Mechanical locking problem on the actuator.
•
Actuator position sensor not working.
•
Throttle lever disconnected.
•
Throttle lever fault.
SYSTEM OVERRIDE
If for any reason there is a requirement to
increase the RPM of the engine without
moving the vessel, it is possible to disable
the actuator to control the engine RPM only.
To access this mode, press and hold the "+"
and "–" buttons simultaneously for 5 seconds.
Moving the throttle lever will now only operate
the engine RPM, with the bucket remaining
stationary in the NEUTRAL position. To exit
from this mode and regain control of the
actuator the system must be powered off and
restarted.
