Control Heads

A control station is a location from which the boat can be operated. The

control station may consist of a single- or dual-lever Control Head, multiple

Control Heads, or a side mount Control Head assembly, and associated wiringharnesses. The control heads allow the user to control the drive system.

Control Heads provide the following information to the EC300 Control:

Selection of the active control station

Indication that the station is active

Direction (forward or reverse) and throttle command

Desired mode of operation

Multiple control stations allow the boats drive system to be controlled from

more than one location on the boat. Only one control station is active at a

time. The operator selects the active control station by pressing the Station

Select button on the control head (also referred to as lever head).

In a single engine system, as shown in Figure 1 and Figure 3, a single lever

control head is installed because only one lever is required to control the

drive system. In a multiple drive train installation, such as the two engine

installation shown in Figures 2 and 4, a dual lever control head is required.

In this conguration the port lever of each control head is connected tothe port engine controller and the starboard lever of each control head is

connected to the starboard engine controller. Station 1s control head levers

are connected to J1 on the port and starboard controllers and station 2s

control head levers are connected to J2 on the port and starboard controllers.

These connections allow either station to be selected as the active station

and to control both drive trains.

Station Expansion Marine Control (EC300/SE)

The EC300 Control can directly connect with a maximum of three control

heads, at connectors J1, J2, and J3. Station Expansion Marine Controls are

required when four or ve control heads are used per EC300 Control. Each

Station Expansion Marine Control allows three control heads to be connected

to J4 of the EC300 Control.

EC300 Control

The EC300 Control is the interface between the operator and the drive system

and it must be congured properly to match the drive train components.

Instructions for performing conguration are provided in Chapter 4 of thismanual.

One EC300 Control is required for each of the boats drive trains. For

boats with only one drive train, one EC300 Control is required and it is

congured as the port control. For boats with more than one drive train,

the EC300 Controls for each drive train are connected together via an

RS-485 link (at J10 of each controller) to allow the controllers to communicate

and control multiple drive trains as a system.

During eld setup using the MFST, a unique identication number is assigned

to each controller. This I.D. number is considered the controllers address. For

multi-drive train installations, the controllers continually pass information to

each other over the RS-485 bus. This information includes the active station

I.D., target station I.D. (used in station transfer), engine speed, propeller

speed, lever position, and current mode as selected by the operator at the

active control station.

The port controller manages the ow of information between all controllers

in the system by sending requests for information to the other controller(s)

and processing the responses. The port controller polls all controllers in the

system in a round-robin fashion until all have been polled. Polling time variesdepending on the number of controllers in the system, the systems state,

and events in process, but typically takes less than one second even in a

boat with eight controllers.

The controller supports up to three Twin Disc analog or digital Control Heads

(or up to six Control Heads, if Station Expansion Marine Controls are used).

Control signals from the bridge to the controller are described in the following

paragraph.

Bridge Signals

Bridge signals are derived from the Control Heads as outlined in Table 1.

Connectors J1, J2, and J3 support the following inputs:

8 Alarm Relay Contact

- COM

Sync Mode

Sync Mode is for use only on boats with more than one drive train. The EC300Control supports two methods of engine speed synchronization: normal sync

and single lever sync. With either type of sync, the mode switch must be at

either the Cruise Sync or Express Sync position and all levers at the active

control station must be at or past the forward detent.

Normal Sync: In Normal Sync mode, the port controller is always

the sync master (not to be confused with communication master).

All other controllers are sync slaves. As long as the lever for a sync

slave is within about 15 degrees of the lever of the sync master, the

sync slave adjusts its engine speed to match the speed of the sync

master engine. If the levers are more than 15 degrees apart, the slavechanges its engine speed as much as possible to make the speeds

match, but when the limit is reached, no further adjustment can take

place so the engine speeds will differ.

8/12/2019 0006_EC300 MFST

24/120

24



Single Lever Sync (SLS): In SLS mode, the sync master controller is

determined either by the conguration or by an optional switch at the

active control station.

If the switch is not present, the sync master is determinedby the conguration and can be either the port-most or the

starboard-most controller.

If the switch is present, the operator uses the switch to choose

the port-most or the starboard-most controller as the sync

master. The choice must be made with all of the levers at

the active station at the neutral detent. Changing the switch

position when the levers are not in the neutral detent position

has no effect until all levers are returned to neutral.

When operating in SLS, all levers must be at or past the forward

detent. The lever position of the sync master determines the engineor propeller speed of all drive trains. The levers of the sync slave

controllers can be in any position at or past the forward detent. The

master controller commands each engine to the same speed, then

the slave controllers make small adjustments in the throttle output to

compensate for lever calibration differences.

If anything happens to cause the system to drop SLS mode, the slave

controllers slowly ramp the throttles to the current position of their

levers to prevent abrupt changes in boat speed.

If any lever is moved from forward, that control will no longer be in sync mode.It is possible to have the mode switch in a sync position and still maneuver

the boat by putting one or all drive trains in reverse. Sync mode is re-entered

when all levers are returned to forward and the lever positions are matched

within 15 degrees, regardless of the sync type.

To start the engine the transmission must be in neutral. A neutral start relay

is provided on J5-9 (Normally Open) and J5-10 (Common). When the engine

start conditions are met, the neutral start relay closes the path between

J5-9 and J5-10. Then, when the start switch is pressed, battery voltage is

routed through J5-9 to J5-10 to the starter solenoid or the start relay. When

power is connected to the solenoid, the solenoid energizes and pulls in, thus

connecting power to the starter motor. How J5-10 is connected is determined

by the starter solenoid current draw as shown in Table 3.

Note: A manual override switch may be installed in series withthe EC300 Controls Neutral Start Relay. If this is the

case, the manual override switch must be closed for the

solenoid to receive power.

Closing the ignition switch provides battery voltage to ignition pin J8-1, which

signals the EC300 Control of the closure. The ignition switch and the start

switch may be part of the same switch mechanism.

Depending upon the engine manufacturer, the throttle output signal is a

programmed voltage, current, or a pulse train. The EC300 Control is capableof accommodating all engines that are listed in the MFST software during

the conguration process. (See Chapter 2 for conguration procedures.)

Twin Disc, Incorporated Conguration


Conguration

Introduction

After installation in the boat, the EC300 Control must be congured in

order to match the control operating parameters to the customer-selected

hardware, desired operational congurations, and optional equipment. This

chapter provides information on installing the MFST software and setting the

congurable parameters.

The following variables can be congured:

Lever arrangement

Engine type and throttle parameters

Transmission type, ratio, and related parameters

Optional inputs for monitoring by the controller.

Conguration is performed by a technician using the EC300 Marine Field

Support Tool (MFST). The MFST is a Windows-based software program

and is generally used on a portable laptop computer. After the computer is

connected to the EC300 Control System, the MFST instructs the installation

technician to perform the steps in the proper sequence. The gures included

in this chapter are screen shots from installation of a system with two

Controllers (twin drive train boat).

Note: If the EC300 Control is ever replaced, its conguration

must be downloaded to the replacement EC300

Control.

Twin Disc, IncorporatedConguration


Gathering Conguration Data

Twin Disc produces a complete installation package from the information

collected on the Marine Set Up Sheet for the boat. The following documentation

for the system to be congured should be available prior to launching theMFST:

Marine Set Up Sheet

System drawing set consisting of one or more pages, depending on

system size

Appendix A provides a form that can be lled out with the systems information

from the above mentioned sources. The form follows the MFST conguration

screens and helps ensure that all relevant parameters are identied prior to

starting the conguration process on-site.

EC300 Control Addressing

It is very important to understand how the EC300 Control(s) are addressed

in the system because if they are not congured correctly, communications

will fail and certain features will not function.

In a multi-drive train system, during initial conguration the MFST requests

that the EC300 Controls be turned on in a specic order. This creates

addresses in each of the EC300 Controls. The following screen, displayedduring initial setup, shows how the drive trains are identied in MFST and

thus their connected EC300 Controls.

8/12/2019 0006_EC300 MFST

35/120

35



Each drive trains connected EC300 Control is designated a two-digit address

(XY) to correlate with a dual control head as follows:

The rst digit (X) identies the control head, where:

0 = First

1 = Second

2 = Third

3 = Fourth

The second digit (Y) identies port (0) or starboard (1)

For example, the port lever of the fourth control head would have an address

of 30. See Figure 6 for examples of addressing.

during initial setup. It is suggested that each EC300 Control be labeled so

that it is correctly identied during setup.

Templates

Existing archive les can be used as templates for new systems. To use an

existing conguration as a template for a new installation, locate the archive

le for an existing installation that is the same as or similar to the installationyou need to congure. Then, when performing the conguration procedure

in the following section, click the Openbutton when the option is presented

to open a window displaying archived conguration les. Select the le you

wish to use as the template to proceed with the conguration process. You

can now edit the conguration information as required to meet the needs of

the new installation. When you save the edited le, it is saved with the boat

name entered when you clicked Field Setup so the le used as the template

is not overwritten.

When a system is created, a .bin le is created for each controller in the

system. For example, four .bin les are created for a boat with four drive

trains. During creation of a multi-drive train system, each controller is

designated a unique address. In a two-drive train boat, the les are actually

the same unless Update All was turned off, which would not have updated

both conguration les after each change.

This is not true for boats with more than two drive trains after eld setup has

been run, because the upper digit of the address has been set. The last two

digits of the le name are the address of the controller. The rest of the le

name is the serial number of the controller.

Context-Sensitive Help System

The MFST application provides an extensive help system. Context-sensitive

help can be viewed by performing the following procedure.

Click the1. ?in the upper right of the screen. A ?is displayed attached

to the cursor.

Installation : This function allows you to install new rmware (the

EC300 Controls operating system) on the connected EC300 Control.

See Checking for MFST and EC300 Control Software Updates on

page 38.

Monitoring : This function provides a window that displays the

transmission input RPM and the propeller RPM.

During eld setup the code in the controller and the MFST is updated at

each change. All features and parameters are initially programmed with

invalid values. As new features are added, their specic memory locations

are programmed with valid values.

When the MFST nds illegal values, it displays an error list window as in

the example shown below. This list includes as many sections as there are

controllers in the system. In this example, the controller is identied by its

serial number. Illegal values are shown along with the default value to which

they are being changed. Scroll down to view a section for each controller in

the system. The values are updated automatically. Clicking Close updates

all controllers in the system. When this is done, the normal Field Modify

screen is displayed.
