Product Overview

Evolution is a system of electronic components that give you autopilot control of your vessel’s steering system. In conjunction with a compatible pilot control head, the Evolution components enable you to directly control the vessel’s steering system and provide navigation commands, such as navigating to pre-determined tracks and waypoints for example. The Evolution system provides a number of features to ensure ease of installation and minimal setup:

  • Flexible mounting options — The EV-1 unit can be mounted flat on a deck or alternatively on a bracket, for direct mounting to a mast, wall or other surface.
    Note: The arrow on the front of the EV-1 unit must be in parallel alignment with the vessel’s head (along the longitudinal axis of the vessel).
  • Simple connections — all Evolution system components are easily and simply connected to a single SeaTalkng backbone cable.
  • High accuracy — accurate course-keeping, to within +/- 2 degrees, in all conditions.
  • Built-in heading and attitude sensor — no additional fluxgate compass required.
  • Automatic setup — no calibration required. The Rudder Gain, Rudder Damping and Counter Rudder, and compass calibration settings required by existing autopilots are no longer necessary.
    The Evolution system consists of the following components:
    Component Purpose
    EV-1 autopilot with Attitude Heading Reference Sensor (AHRS) The primary heading sensor and course computer, incorporating an attitude 9-axis sensor. This sensor replaces the fluxgate compass typical in existing autopilot systems.
    Actuator Control Unit (ACU) Houses the main power and drive electronics for direct connection to a vessel’s steering system.

Schematic diagram
A schematic diagram is an essential part of planning any installation. It is also useful for any future additions or maintenance of the system. The diagram should include:

  • Location of all components.
  • Connectors, cable types, routes and lengths.

Software requirements
Correct operation of this product requires software version 2.0 or later for p70 and p70R pilot control heads.

Required additional components
To complete your autopilot system, you will need the following components and data sources in addition to the Evolution components.

Essential:

  • Compatible autopilot control head.
  • Drive unit appropriate for your vessel and Evolution EV-1 and ACU units.
  • Power cables.

Recommended:

  • Compatible speed data source. The autopilot uses speed data when making calculations relating to navigation. As a minimum, this information must come from a GPS receiver providing SOG (Speed Over Ground) data, or ideally from a dedicated speed sensor.
  • Compatible wind data source (only required for sailing vessels). The autopilot uses wind vane data to steer relative to a specified wind angle. This data must come from an analog wind transducer connected to the SeaTalkng bus.
  • Rudder angle sensor. To ensure optimum autopilot performance, Raymarine highly recommends that a rudder reference unit is used.
    Optional:
  • Position data source. The autopilot uses position data when following routes and calculating the optimum course to steer.
    This data is usually supplied by a GPS receiver on the SeaTalkng bus.

Multiple data sources (MDS) overview
Installations that include multiple instances of data sources can cause data conflicts. An example is an installation featuring more than one source of GPS data.
MDS enables you to manage conflicts involving the following  types of data:

  • GPS Position.
  • Heading.
  • Depth.
  • Speed.
  • Wind.

Typically this exercise is completed as part of the initial installation, or when new equipment is added.
If this exercise is NOT completed the system will automatically attempt to resolve data conflicts. However, this may result in the system choosing a source of data that you do not want to use.
If MDS is available the system can list the available data sources and allow you to select your preferred data source. For MDS to be available all products in the system that use the data sources listed above must be MDS-compliant. The system can list any products that are NOT compliant. It may be necessary to upgrade the software for these non-compliant products to make them compliant. Visit the Raymarine website (www.raymarine.com) to obtain the latest software for your products. If MDS-compliant software is not available and you do NOT want the system to automatically attempt to resolve data conflicts, any non-compliant product(s) can be removed or replaced to ensure the entire system is MDS-compliant.
Multiple data source exceptions
With the Evolution system, there are a number of important exceptions to the handling of multiple sources of certain types of data.
Specifically:

  • Heading data — If a non-Evolution source of heading data is designated by the user, the Evolution system components will combine this heading data with its own gyro and accelerometer data, and then use the improved heading data. This combined heading data will also be available to other equipment on the SeaTalkng bus.
  • Rudder angle data — Where there are multiple sources of rudder reference information, the Evolution system components will ignore rudder angle inputs from any rudder reference units that are NOT connected directly to an Evolution ACU.

Autopilot controllers
The Evolution system is designed for use with the p70 and p70R autopilot control heads.
It can also be used with a number of other SeaTalkng and SeaTalk autopilot control heads, but with limited functionality.Raymarine ACU-100 Actuator Control Unit-4

Hydraulic pumps

Raymarine autopilots connect to hydraulic steering systems using a rugged hydraulic pump matched to the capacity of the hydraulic steering system.

To find a suitable pump, you’ll need to know the size (in cc) of the hydraulic cylinder ram(s) mounted to the rudder on vessels featuring an inboard engine, or to the drive unit on vessels featuring outboard engines. Refer to your steering system documentation for this information. Alternatively, you can look on the cylinder ram itself for the brand and model number.

Once you have this figure, refer to the Cylinder Ram Size Chart on the Raymarine website to determine which hydraulic autopilot pump is compatible with your vessel’s hydraulic steering system: http://www.raymarine.co.uk/view/?id=209.

Seatalkng

SeaTalkng (Next Generation) is an enhanced protocol for the connection of compatible marine instruments and equipment. It replaces the older SeaTalk and SeaTalk2 protocols. SeaTalkng utilizes a single backbone to which compatible instruments connect using a spur. Data and power are carried within the backbone. Devices that have a low draw can be powered from the network, although high-current equipment will need to have a separate power connection. SeaTalkng is a proprietary extension to NMEA 2000 and the proven CAN bus technology. Compatible NMEA 2000 and SeaTalk / SeaTalk2 devices can also be connected using the appropriate interfaces or adaptor cables as required.

Cables and connections

General cabling guidance
Cable types and length
It is important to use cables of the appropriate type and length

  • Unless otherwise stated use only standard cables of the correct type, supplied by Raymarine.
  • Ensure that any non-Raymarine cables are of the correct quality and gauge. For example, longer power cable runs may require larger wire gauges to minimize voltage drop along the run.

Routing cables
Cables must be routed correctly, to maximize performance and prolong cable life.

  • Do NOT bend cables excessively. Wherever possible, ensure a minimum bend diameter of 200 mm (8 in) / minimum bend radius of 100 mm (4 in).Raymarine ACU-100 Actuator Control Unit-11
  • Protect all cables from physical damage and exposure to heat.
    Use trunking or conduit where possible. Do NOT run cables through bilges or doorways, or close to moving or hot objects.
  • Secure cables in place using tie-wraps or lacing twine. Coil any extra cable and tie it out of the way.
  • Where a cable passes through an exposed bulkhead or deckhead, use a suitable watertight feed-through.
  • Do NOT run cables near to engines or fluorescent lights. Always route data cables as far away as possible from:
  • other equipment and cables,
  • high current carrying ac and dc power lines,
  • antennae.

Strain relief

Ensure adequate strain relief is provided. Protect connectors from strain and ensure they will not pull out under extreme sea conditions.
Circuit isolation
Appropriate circuit isolation is required for installations using both AC and DC current:

  • Always use isolating transformers or a separate power inverter to run PCs, processors, displays and other sensitive electronic instruments or devices.
  • Always use an isolating transformer with Weather FAX audio cables.
  • Always use an isolated power supply when using a 3rd party audio amplifier.
  • Always use an RS232/NMEA converter with optical isolation on the signal lines.
  • Always make sure that PC’s or other sensitive electronic devices have a dedicated power circuit.

Cable shielding
Ensure that all data cables are properly shielded that the cable shielding is intact (e.g. hasn’t been scraped off by being squeezed through a tight area).

Power connection
Power connection — EV-1
The power for the EV-1 unit is provided by the SeaTalkng system.

  • The units must be connected to a SeaTalkng backbone. This is typically achieved using a SeaTalkng 5-way connector block or T-piece connector.
  • The SeaTalkng system requires only ONE 12 V power source.
    This can be provided by:
    • A battery.
    • An Evolution ACU, via a SeaTalkng system.
      If your vessel has a 24 V supply a suitable voltage convertor is required.
  • The power source must be protected by a 5 A fuse or a circuit breaker providing equivalent protection.
  • SeaTalkng cables carry both data and power signals. The power is supplied to the EV-1 via a SeaTalkng spur cable.
  • Refer to the SeaTalkng reference manual for more information on general SeaTalkng power requirements.

Power connection colors

Grounding — Dedicated drain wire required

This product includes a dedicated drain conductor (screen) for connection to a vessel’s RF ground point. It is important that an effective RF ground is connected to the unit. The unit can be grounded by connecting the drain conductor (screen) to the vessel’s RF ground point. On vessels without an RF ground system the drain conductor (screen) should be connected directly to the negative battery terminal.
The dc power system should be either:

  • Negative grounded, with the negative battery terminal connected to the vessel’s ground; or
  • Floating, with neither battery terminal connected to the vessel’s ground.

If several items require grounding, they may first be connected to a single local point (e.g. within a switch panel), with this point connected via a single, appropriately-rated conductor, to the vessel’s common RF ground point.
Implementation
The preferred minimum requirement for the path to ground is via a flat tinned copper braid, with a 30 A rating (1/4 inch) or greater. If this is not possible, an equivalent stranded wire conductor maybe used, rated as follows:

  • for runs of <1 m (3 ft), use 6 mm2 (#10 AWG) or greater.
  • for runs of >1 m (3 ft), use 8 mm2 (#8 AWG) or greater.
    In any grounding system, always keep the length of connecting braid or wires as short as possible.

Fuses and circuit protection
There are 3 levels of power protection in the autopilot system. The motor and associated cables are initially protected by the current sensing and stall condition detection within the ACU hardware and software. The second level of protection is provided to these parts and the ACU components by the unit’s main power fuse. Protection for the entire autopilot system and its wiring back to the main power distribution panel is provided by your vessel’s circuit breaker/fuse.
Power supply circuit protection
Protect the power supply for the Evolution system at the distribution board with a fuse or circuit breaker that is suitable for the ACU. For guidance, refer to the main power fuse rating stated on the ACU connector panel. If in doubt, consult your local dealer.
Internal fuses
The ACU uses standard automotive blade fuses. Spare fuses are located on the underside of the removable cover.Raymarine ACU-100 Actuator Control Unit-19

Where possible, connect individual items of equipment to individual circuit breakers. Where this is not possible, use individual in-line fuses to provide the necessary protection.
Power and drive cables
Important electrical considerations when planning cable runs and equipment location.
The amount of electrical current available to the autopilot system components will be impacted by the length and gauge of thecables used to connect all the components. When determining the cable required for the power and drive connections it is necessary to consider the combined cable length of both connections.Raymarine ACU-100 Actuator Control Unit-21

B Blue Clutch -ve

Motor power output

ACU–200 ACU-400
15 A (maximum continuous output) 30 A (maximum continuous output)

Note: The motor output has full short-circuit and over-current protection. Should either of the motor output connections be shorted to ground, there should be no permanent damage to the autopilot.
Clutch power output

ACU–200 ACU-400
Up to 2A continuous at 12 V on 12 V and 24 V systems. •          Up to 4 A continuous at 12 V on 12 V systems.

•          Up to 4 A continuous at 24 V on 24 V systems.

•          Up to 4 A continuous at 12 V on 24 V systems.

Note: The use of a clutch drive will have an impact on the amount of electrical current available to the SeaTalkng system. On 24 V systems, there is an 8 A / 12 V maximum supply for the SeaTalkng system and clutch drive combined. For example, if the clutch requires 4 A, the SeaTalkng supply can only deliver 4 A to the rest of the SeaTalkng system.
Note: The clutch output on all ACU variants has full short-circuit and over-current protection. Should either of the clutch output connections be shorted to the ground, there should be no permanent damage to the autopilot.

Clutch voltage switchRaymarine ACU-100 Actuator Control Unit-24
If the drive has a separate clutch connection, you must ensure that the clutch voltage switch on the ACU is set correctly to suit the connected drive.
Important: To avoid potential damage to equipment, ensure the voltage selector switch is set to the correct setting. The clutch voltage may be different from that of the drive itself, for example, the range of both 12 V and 24 V Raymarine drives all have a 12 V clutch. If in doubt, consult your local dealer.

SeaTalk connection
The Evolution system is designed for use with the latest SeaTalkng autopilot control heads. You can also use a SeaTalk autopilot control head, but with limited functionality. Refer to the SeaTalk to SeaTalkng converter handbook (87121) for more information on these limitations, and how to connect a SeaTalk autopilot control head to an Evolution system.
Rudder reference connection
A rudder reference sensor unit can be connected to the ACU to provide rudder angle information to the autopilot system. The connection of a rudder reference unit is highly recommended, to help ensure optimum autopilot performance. A rudder reference unit converts its movement information to the rudder angle in +/- degrees.
Certain environmental conditions such as cross-current can cause the autopilot system to steer persistently to port or starboard, even when the rudder is centered. With a rudder reference unit connected to your autopilot system, you can use an autopilot control head to specify an offset angle in +/- degrees to compensate for inaccurate rudder angle information caused by such conditions.
The more accurate the rudder angle information, the more accurately the autopilot system can keep to a correct course. The rudder reference unit connected to the ACU connection panel is shown below.Raymarine ACU-100 Actuator Control Unit-33

LED indications — EV-1Raymarine ACU-100 Actuator Control Unit-49
Alarms

Alarms are raised by the autopilot system to alert you to mechanical and electrical conditions requiring your attention. The Evolution components transmit alarm alerts on the SeaTalkng network for display on autopilot control heads and multifunction displays, along with an audible alert. The Evolution components stop raising an alarm when the alarm condition ceases or the alarm is acknowledged on the autopilot control head or multifunction display. If the alarm is safety-critical it will be raised again after a timed delay.
Unless otherwise stated in the table below, you should respond to alarms by selecting OK or Acknowledge on your autopilot control head or multifunction display.

Alarm Message Possible causes Solution
OFF COURSE Autopilot has deviated from planned course. Check your vessel position and if necessary take manual control to steer the vessel back on course.
WIND SHIFT Autopilot is unable to maintain navigation to the current wind angle.
LOW BATTERY Power supply voltage has dropped below acceptable limits. Caused by low battery voltage or voltage drop at the ACU unit (EV-1 systems only), due to poor connections or inadequate wiring. Acknowledge the alarm and then start the engine to recharge the battery. If problem persists, check wiring connections and that the quality and gauge of wiring is adequate for the current draw of the drive unit.
LARGE XTE Large cross-track error. The autopilot has deviated more than expected from a planned course. Check your vessel position and if necessary take manual control to steer the vessel back on course.
CU DISCONNECTED The autopilot control head has been disconnected. •          Check the physical cables and connections between the autopilot control head and the SeaTalkng system. Also between the EV-1 / EV-2 and the SeaTalkng system.

•          If the autopilot control head is connected via a SeaTalk to SeaTalkng converter, check the converter is using the latest software version.

AUTO RELEASE Possible fault with rudder reference unit. Alternatively, if your autopilot system includes a stern I/O drive, you have taken manual control of the steering while the pilot is in Auto mode. •          Check rudder reference unit connections.

•          For systems using the Volvo Penta EVC drive interface unit, check the unit is operating correctly.

WAYPOINT ADVANCE The autopilot has steered the vessel to the current waypoint. Acknowledge the turn to the next waypoint.
DRIVE STOPPED •          Motor / steering has not moved within 20 seconds of a course change command.

•          The autopilot is unable to turn the rudder (either because the weather load on the helm is too high, or if the rudder position sensor has passed beyond the preset rudder limits or rudder end-stops.

•          Autopilot resets due to an external event (such as use of the sleep switch, or faulty wiring causing the autopilot components to power cycle).

•          Autopilot resets due to software error.

•          Check the rudder reference unit has been installed correctly to reflect the limits and end-stops of the vessel’s rudder system.

•          For EV-1 systems, check ACU drive output voltage and drive and clutch voltage output (if applicable).

•          For EV-1 systems, check all connections to ACU.

•          Check all connections to drive unit.

•          Check that the drive unit operates and is not stalled.

•          Check steering system is secure.

NO RUDDER REFERENCE No rudder reference unit is detected, or the rudder reference unit has turned outside its operational range (50 degrees). If a rudder reference unit is installed, check the wiring. Inspect the unit for possible damage.
STALL DETECTED Motor speed dropped too low for given course change or motor stalling. This can be caused by a faulty drive unit or steering fault. Alternatively, the steering hard-over time may be too slow. •          Check that the drive unit operates and is not stalled.

•          Check the steering hard-over time.

CLUTCH OVERLOAD The clutch for the drive system is demanding a greater power output than is supported by the clutch power output of the Evolution components. Refer to the clutch power output ratings provided in the Installation instructions for the relevant Evolution components, and ensure the clutch for the drive unit does not exceed this power output.
CURRENT OVERLOAD Serious drive failure; the drive is demanding too much electrical current due to short-circuit or jamming. Caused by a faulty drive unit or motor, or wiring short-circuit. Alternatively, a fault in the steering system may be causing the drive unit to lock-up. Check the drive unit.
ROUTE COMPLETE Your vessel has arrived at the end of the current route. No action required.
Alarm Message Possible causes Solution
NO DATA •          The autopilot is in Wind Vane mode and has not received wind angle data for 32 seconds.

•          The autopilot is in Track mode and is not receiving navigation data, or the rudder position sensor is receiving a low-strength signal. This will clear when the signal improves.

Check the connections to the wind transducer, multifunction display, and autopilot control head (as appropriate).
PILOT STARTUP Autopilot components are initializing. Some components may take a moment to startup.
NO WIND DATA The autopilot is in Wind Vane mode and has not received wind angle data for 32 seconds. Check the connections to the wind transducer.
NO SPEED DATA The autopilot has not received speed (STW or SOG) data for 10 seconds, while in Auto mode. Check the connections to the speed transducer. Pilot does not require speed data in order to operate. However, it does enhance the overall performance when in Auto mode.
NO COMPASS The EV-1 or EV-2 is not receiving heading data. •          Check the connections to the EV-1 / EV-2.

•          Power cycle the EV-1 / EV-2, by removing and then reconnecting the SeaTalkng cable.

RATEGYRO FAIL The internal rate gyro on the EV-1 or EV-2 unit has developed a fault. This will be evident as a compass issue and could cause the compass heading to deviate or lock-up. If the problem persists, contact your local Raymarine service center.
MOTOR POWER SWAPPED On the Evolution ACU unit, the motor cables are connected to the power terminals, and vice versa. Switch off the power to the unit and reconnect correctly.
NO GPS DATA A source of GPS data is not connected to the SeaTalkng system. Check connections to the GPS data source.
JOYSTICK FAULT A fault has occurred with the joystick. This alarm applies only to autopilot systems that include a joystick controller. Check the connections to, and operation of the joystick.
NO IPS (NO DRIVE DETECTED) Loss of communications between the EV-1 and ACU, or EV-2 and drive interface unit. Check all physical data connections between these devices, as appropriate.
PILOT RESET NORMAL (UNEXPECTED HARDWARE RESET) •          Autopilot resets due to an external event (such as use of the sleep switch, or faulty wiring causing the autopilot components to power cycle). Check all system wiring, especially power-related wiring.
PILOT RESET EXCEPTION (UNEXPECTED SOFTWARE RESET) The EV-1 / EV-2 software has detected a fault it cannot recover from, and has reset the pilot. Wait approximately 1 minute for the EV-1 / EV-2 to reset and re-initialize.

FAQS

FAQS

What sensors are used in autopilot?

Autopilot and stability augmentation systems commonly used on aircraft employ sensors including magnetometers, accelerometers, and gyroscopes to provide information on the vehicle motion.

Does autopilot use PID controller?

The proposed PID control design is used and applied to autopilot ship model. The actual closed-loop is a combination of the PID response, and the GPC output predicted system trajectories.

Does a autopilot adjust the sails?

Autopilots for sailboats are useful assisting tools for sailors. Commer- cially available autopilots are not able to actuate the sails. This means that actual autopilots can not control the sails actuation while the boat keeps the desired course.

What are the 3 basic autopilot components?

The attitude and directional gyros, the turn coordinator, and an altitude control are the autopilot sensing elements.

What is chirp sonar Raymarine?

CHIRP transmissions allow more sonar power to penetrate the water – in fact x10 more power when compared to conventional sonar modules. ClearPulse CHIRP technology takes advantage of a wide spectrum of sonar signals to deliver amazing detail and accuracy.

How does an autohelm work?

Autopilot operation is simple, put the vessel on the desired heading, hold the course for a few seconds, press AUTO, and release the helm. The autopilot will lock the course in memory, and will respond with helm corrections to keep your boat on this course.

Does Raymarine have Wi-Fi?

The T1 Linear drive will require 0.5A for the clutch operation and will draw a max of 15A when stalled, during ‘normal’ operation (typically, well balanced sail plan, a couple of degrees of weather helm), then 6-8 Amps continuous.

How does an autohelm work?

Autopilot is the use of an automatic system to control the rudder on the vessel. Use of autopilot can reduce the fuel consumption by smoothing out the large-angle rudder movements used to hold a steady course.

How does autopilot work on a ship?

Access aSeries anywhere onboard with Raymarine apps. Play and control MP3 audio on your smartphone remotely using Bluetooth. Download Navionics charts and updates right from the Navionics Boating App on your phone. Sync with Navionics Boating App.

 How does a Raymarine autopilot work?

To enter the autopilot mode and engage the autopilot, press the red “auto” button. To disengage the autopilot, press the red “standby” button. To make 1° changes in your heading to port, press the “-1” button.

Is Raymarine an autohelm?

Raymarine was originally an independent UK company. Autohelm was a brand name for its autopilots.

Is autopilot Closed Loop?

Auto pilot for an aircraft is closed loop system and remaining all are open loop systems.

How do you engage and disengage an autopilot?

Most autopilots have several ways to disengage the system. There is a button under your thumb on the control wheel horn that, when pushed, disengages the autopilot. In most systems pushing the button all the way down also removes power from the electric pitch trim.

Can you sleep while on autopilot?

This leads to them making dangerous decisions, such as sleeping behind the wheel, that they would never dream of doing in another car. The reason you’re not legally allowed to sleep while a Tesla is on Autopilot is that, while the system has proven to be very reliable, it’s not infallible. Things can still go wrong.

Does autopilot correct for wind?

While to auto land system can typically work with some crosswind and some gusts, limits are much lower compared to manual landing.
