This chapter provides a functional description of the Three60 Precision Control System as an aid in understanding system operation. The Three60 Precision Control System is comprised of two major subsystems :
- Control System
- Hydraulic Thruster System
The Three60 Precision Control System can be operated in two modes:
- Joystick mode: The Three60 Precision Control System provides simplified, single-point joystick control of thrusters and powertrains when the vessel requires precise maneuvering.
- Leverhead mode: The vessel powertrains are controlled using the leverheads and the thrusters are controlled using the thruster control panels.

Three60 Precision Control System
A control station is a location from which the boat can be operated. On a vessel with Three60 Precision Control System the control station may consist of any of the following:
- A joystick that is used to control the bow thruster, the conventional drive trains, and if installed, the stern thruster, when the system is in Joystick mode.
- One or two thruster control panels to control the bow thruster and, if installed, the optional stern thruster independent of the conventional drive trains when the system is in Leverhead mode.
- Leverheads to control the power trains independent of the thrusters when the system is in Leverhead mode.
The joysticks provide the following information to the Joystick Control:
- Selection of the active control station
- Direction and throttle command
Multiple control stations allow the drive system of the boat to be controlled from more than one location on the boat. Only one power train control station or joystick station is active at a time. A thruster control panel station can be active only when all joystick stations are inactive. The operator selects the joystick as the active control system by pressing the "Station Select" button.
Note: When a power train leverhead or a thruster control panel is selected as the active control station, the joystick is deselected and inactive.
The Joystick Control is the interface between the operator controls and both the conventional drive system and thrusters. The joystick control must be configured properly to match the installed components. Instructions for performing configuration are provided in Configuration
The Joystick Control accepts input from the joystick and then commands the thrusters directly via the pulse width modulation (PWM) outputs and the conventional drive trains via the associated Powertrain Controls.

Illustration 5 | g03465277 |
It is very important to understand how the Powertrain Controls are addressed in the system to ensure proper inter-control communications and that all features function as expected.
During the configuration of a Three60 Precision Control System, the support tool requests that the Powertrain Controlsare turned on in a specific order. This action creates a two-digit address (XY) that correlates with a leverhead as shown in Illustration 5
A control station is a location from which the boat can be operated. The control station consists dual-lever leverhead, multiple leverheads, or a Palm Beach style leverhead assembly, and associated wiring harnesses. The leverheads allow the user to control the drive system. Leverheads provide the following information to the Powertrain 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 drive system of the boat 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 leverhead.
The port lever of each leverhead is connected to the port Powertrain Control and the starboard lever of each leverhead is connected to the starboard Powertrain Control. Station 1's leverhead levers are connected to J1 on the port and starboard Powertrain Control and station 2's leverhead levers are connected to J2 on the port and starboard Powertrain Control.
These connections allow either station to be selected as the active station and to control both power trains.
The Powertrain Control is the interface between the operator controls and the conventional port and starboard power trains and must be configured properly to match the drive train components. Instructions for performing configuration are provided in "Configuration"
One Powertrain Control is required for each power train. The Powertrain Controls for each power train are connected together via an RS-485 link (at J10 of each Powertrain Control) to allow the Powertrain Controls to communicate and control multiple power trains as a system.
During field setup using the Three60 Precision Control System support tool, a unique identification number is assigned to each Powertrain Control. This identification number is considered the Powertrain Control address. The Powertrain Controls continually pass information to each other over the RS-485 bus. This information includes the active station identification number, target station identification number. (used in station transfer), input speed, propeller speed, lever position, and current mode as selected by the operator at the active control station.
The port Powertrain Control manages the flow of information between it and the starboard Powertrain Control by polling the starboard Powertrain Control for information and processing its responses. Polling time varies depending on the system's state and events in process, but typically takes less than one second
The following sections provide information about the Powertrain Control electrical interfaces.

The following table lists the engine control signals routed to J5.

7 | Not used | |
8 | Not used | |
9 | Neutral Start Relay Contact - NO | Connected to the Start switch of the boat. When the Start switch is pressed, battery voltage is connected to the control. The relay contact must be connected in series with the engine start signal and the transmission manual override switch to prevent engine cranking when the transmission is not in neutral. |
10 | Neutral Start Relay Contact - Com | This signal is connected to the starter solenoid and depends on the starter solenoid current draw:
· 5 A or greater: Power is routed to the coil of a relay. · Less than 5 A: Power is routed directly to the solenoid. |
11 | Input Speed Sensor | The input speed sensor generates a pulse as each tooth of the gear or speed wheel passes. The control determines input speed based on the time between pulses. |
12 | Input Speed Sensor Return | This pin is the ground for the input speed sensor. |
The transmission must be in neutral to start the engine. 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 it 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 13.
Note: A manual override switch may be installed in series with the Powertrain Control Neutral Start Relay. If so, 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 Powertrain Control of the closure. The ignition switch and the start switch may be part of the same switch mechanism.
The throttle output signal is a pulse width modulated (PWM) pulse train.
