Features and Benefits
The Twin Disc POWER COMMANDER® Model EC200 enhanced
control system is designed to control the engines and
transmissions of a boat or ship, while providing the
propulsion with shift a throttle logic to improve overall
operation and convenience.
A SINGLE LEVER controls throttle and ahead-neutral-astern
selection so operation is effortless. Docking is simplified!
MULTI-FUNCTION SELECTOR lets you select idle speeds for
docking and maneuvering, synchronized engine operation, or trolling
operation with two-speed selections.
A STATION SELECT SWITCH with individual LED indicator for
port and starboard system lets you confirm that the controllers are
ready for your command. Neutral start logic in the EC200 control
provides protection against start-in-gear conditions.
UP TO 6 CONTROL STATIONS are easily provided for by adding
optional station doublers. All controls provide for direct
connection of 3 stations, and doublers can be used on any of the
three station inputs. Custom configurations can provide for more
than 6 stations.
3 PRESET IDLE SPEEDS let you select an idle speed for docking
and maneuvering under various conditions or for just loafing along.
This feature permits "jogging" into gear at higher idle
speeds when docking.
OPTIONAL ENGINE SYNCHRONIZATION electronically matches engine
speeds of two or more engines as long as the control head levers are
kept within 7 degrees of each other and synchronization is switched
on. The control head lever handles are designed to operate jointly
with one hand. Because synchronization mode operates with the
control levers approximately in the same position, abrupt changes of
engine speed are avoided when entering and leaving synchronization
OPTIONAL TROLLING VALVE CONTROL lets you operate your
trolling valve from the same control lever by converting the lever
motion from throttle position command to trolling position command.
Trolling mode and one of two preset engine speeds are selected at
the same time via the multi-function selector. Allowing lever
position for entry and exit from trolling mode is limited to a few
degrees around forward and reverse detent to protect the propulsion
OPTIONAL SHAFT BRAKE CONTROL can synchronize the application
of a shaft brake automatically. Shaft brake application times are
selectable and proportional to the throttle lever and time at that
level. The design allows for faster gear changing without damage to
the propulsion system or stalling of the engine.
OPTIONAL PRESSURE SWITCH input controlled throttle clamp is
available for positive control of engine throttle on high horsepower
transmissions which may exhibit more variability in engagement
times. This feature will prevent damage to clutch plates and
annoying engagement jars caused by engine speed-up prior to closure
of the clutch.
MECHANICAL OVERRIDE "COME HOME" FEATURE is provided
by a clutch in each actuator. In the event of a power failure,
mechanical type throttle and gear selector can be operated manually
without modification or disassembly of any components.

born simplified installation and for sensitive cost reduction.
OPTIONAL ELECTRONIC INTERFACES for engine throttle, gear
selectors, and trolling valves are available for all popular brands
of equipment. All engine interface circuitry is is isolated to
prevent interaction between the engine controller and the EC200
control system. Direct, proportional, and three valve neutral
impulse style drivers are available for gear selector. PWM drivers
are available in either open loop or current feedback configuration
for control of trolling valves.
OPTIONAL EMERGENCY BACKUP system is available for "fully
electronic " EC200 controlled propulsion systems and include a
separate control head, wiring system, and power input from an
SIMPLIFIED INSTALLATION is assured by fully connectored
components and pre-connectored cables. System component connector
sizes are arranged to minimize installation errors and preparation
time. No hydraulic or pneumatic hoses, pumps or valves to plumb,
drain, or leak test. Mechanical actuator directions for throttle,
troll, and gear are selectable by programming shunts conveniently
located in a topside access panel. Synchronization gain, hold in
gear or shaft brake times, and elevated idle level adjustments are
also available via the access panel. Insulated mounting holes in the
control enclosure eliminate the need for isolating sub bases when
mounting controls. Rugged, heavy gauge stainless steel control
enclosures withstand hostile installations and operating stresses.
The basic Model EC200 Control System consists of a control, a
lever assembly and one or more wiring harnesses. The control system
coordinates the transmission direction and the engine RPM. Various
accessories and options are available to interface the EC200 system
to expand configurations and provide performance enhancements
appropriate to today's technologically intense yachts, performance
boats, work boats, and ferry boats.
One control is required for each engine. If the control uses
mechanical actuators, there are rotary devices with electrical
clutches which disengage when power is turned off, allowing manual
operation of transmission direction selector and the throttle,
without the need to dismantle components of the control system. A
separate connector is provided for each of the three station control
head cables, the optional speed sensor cables, a communication
cable, and one multi-purpose cable for power, troll, and options.
The stainless steel control housing includes isolated mounting feet,
a topside access panel for setup, and cable clamp brackets for
mounting mechanical push-pull cables to interface to throttle
governors and transmission selector levers.
Throttle lever and transmission direction selections are
combined into the lever motion. A multi-function rotary
selector provides for idle lever selection, and activation of
troll or synchronization options when available in the system.
A guarded station select push-button and individual station
selected indicators are provided for command and
identification of station in control. The station select
push-button is also used to enter the direction override by
holding down while leaving neutral. Neutral indicators are
also provided and are controlled by circuitry which monitors
the gear command and the output of the control. Neutral
indicators will blink when in neutral gear condition is a
result of a direction override.
Trolling valves can be controlled mechanically or electronically.
In systems that have mechanically positioned governors and
transmission selectors, it may be necessary to use a separate
external troll actuator. In systems with electronic engines or
solenoid shift options, a troll actuator may be included in the main
control enclosure and eliminate the need for additional wiring and
Operation of systems with three to five engines can be simplified
by the use of Phantom Controls to duplicate gear and throttle
commands to inward and center propulsion units. Single, dual, and
triple Phantoms allow full operation of the boat's propulsion from
one dual lever control head when Phantoms are enabled, and separate
levers or combinations when Phantoms are disabled.
