PART 1 - INTRODUCTION

1.1 SYSTEM DESCRIPTION

The HS 2000 is a fully integrated power boat instrumentation
system that displays information obtained from various sensors on
a choice of displays positioned throughout the boat. Information is
fed from the sensors to a Main Processor via a high speed
communications network. From the information gathered by the
sensors the Main Processor distributes information to the various
displays, and can carry out a wide range of functions such as boat
speed, trip log, depth, sea temperature and tidal information.
These functions are controlled from a Full Function Display (FFD).

A typical system is shown in Figure 1.1 - Typical HS 2000 System
Block Diagram.

1.2 PROCESSORS

1.2.1 Main Processor Unit

The Main Processor Unit is the heart of the system and is
responsible for monitoring the data from the sensors. The sensors
measure the following:

Depth
Boat Speed/Log
Compass Heading
Sea Temperature

From this information the Main Processor Unit is then able to
calculate the following additional functions:

Average Boat Speed
Bearing to Waypoint
Bearing Waypoint to Waypoint
Course Over Ground
Dead Reckoned Course and Distance
Distance to Waypoint
Next Waypoint Distance
Speed Over Ground
Stored Log
Time to Waypoint
Trip Log

Once this information is calculated, it is distributed to the displays
via the communications network.

HB-0846-03

1-3

HS 2000 User Manual
Part 1 - Introduction

The Main Processor Unit contains the battery backed memory that
stores all calibration, damping and alarm settings while the power
is OFF; these are adjustable from any FFD.

1.3 SENSORS

1.3.1 Paddle-Wheel

The Paddle-Wheel Speed Sensor is designed primarily for cruising
boats and consists of a paddle-wheel which protrudes through the
hull via a hull-housing. So that the paddle-wheel may be cleaned
at regular intervals, the housing is provided with a flap valve which
closes automatically when the unit is withdrawn into the boat.

1.3.2 XTL Fin Sonic Transducers

The XTL Sonic Speed? Transducer provides an accurate and safe
measurement of speed, distance travelled and depth, essential for
basic navigation and dead reckoning.

The XTL Sonic Speed? System operates on the Doppler principle
by measuring the speed of water travelling between the two Sonic
Speed Transducers and comparing the signals in the XTL
Microsonic control box. Display of linear speed readings up to 35
knots and accurate, stable depth information at high speed,
ensure safety in all depths of water.

The single, one piece transducer is bolted to the bottom of the
boat and has minimal protrusion inside the boat. The one piece
transducer is hydrodynamically designed to offer minimum drag
and if damaged does not threaten the water-tight integrity of the
boat.

HS 2000 User Manual

Part 1 - Introduction

1.3.3 Super Halcyon 3 Fluxgate Compass

This fluxgate compass sensor is fully gimballed in a bath of oil,
ensuring accurate readings at all normal angles of heel and pitch.

1.3.4 Halcyon 2000 Fluxgate Compass

The Halcyon 2000 Compass is a high performance electronic
fluxgate compass for use on power craft. It has been designed
specifically to connect directly onto the proprietary B&G high speed
databus, thus ensuring fast updates and accurate information.

The Halcyon 2000 Compass has the ability to ‘learn’ the magnetic
effects of the vessel on the compass and automatically apply
deviation correction.

1.3.5 Depth Sensor

This can either be a removable through-hull unit, moulded inside
the hull for reduced drag, or part of an XTL Fin assembly. The
depth datum can be offset to display information from the
transducer, water-line or below the keel.

1.4 DISPLAYS

1.4.1 NMEA Full Function Display (FFD)

NMEA is the National Marine Electronics Association, a body
which produces standard specifications for the interconnection of
marine electronic instruments. These standards specify the
electrical signals and the format of the data to be transferred.

The standard system display is the Full Function Display and all
HS 2000 Systems require at least one NMEA FFD for interfacing.
The other display types described in this Section are options with
which the system can be expanded. The FFD is the terminal for
the whole system, allowing control of operational, testing and
calibration functions.

The FFD displays two functions and descriptive text at any one
time. Any system function can be called up on any FFD, and up to
24 FFDs can be connected in the HS 2000 System from which all
functions can be operated.

Part 2 - Operating Information describes in detail the use of the
FFD keyboard to control the HS 2000.

HB-0846-03

1-5

HS 2000 User Manual
Part 1 - Introduction

The NMEA FFD contains an NMEA interface which enables the
HS 2000 to connect to other sensor devices such as position
fixers, autopilots, track plotters and radars provided by other
manufacturers. For example, information from the GPSplus can be
transferred from the bridge to a steering position above decks. The
HS 2000 can also provide information to other instruments; speed
and heading for example can be output to radars, chart plotters
and other navigational devices provided the instruments are
NMEA compatible.

Two further display types can be added to the system, these are:

Standard FFD
20/20 Display

1.4.2 Standard Full Function Display (FFD)

The Standard FFD is identical in operation and appearance to the
NMEA FFD. The only difference is that the Standard FFD does not
have an NMEA interface installed.

1.4.3 20/20 Display

The HS 2000 20/20 Display is a lightweight, large digit, liquid
crystal display and can be configured from any FFD or a remote
button to display system information.

The 20/20's operation is fully explained in Part 5 - Options.

1.5 CALIBRATION

Before using the HS 2000 for navigational purposes, it is important
that the system is calibrated for your installation. The HS 2000
calibration process has been simplified as far as possible, so that
all you require for accurate instrument data is a little background
knowledge and the application of a few simple techniques. These
are fully explained in Part 3 - Calibration.

1.6 DAMPING

A useful feature is that the damping on most functions is user
adjustable. This allows the response of the function to be slowed if
it is too jumpy in rough weather, and similarly the response can be
quickened when in flat water. The damping operates by averaging
the numbers over a time period - the more you increase this time
period the smoother the data readings will be, but the longer it will
take to view the effect of any change; similarly the lower the time
period the larger the jumps in numbers but the response to any
change will be quicker. Remember, high damping for rough
weather, low damping for calm weather.

HB-0846-03

1-6

HS 2000 User Manual

Part 1 - Introduction

Damping should not be confused with the update rate which is the
number of times each second that the function value is sent to the
display. This update rate is fixed for all functions.

1.7 MENU STRUCTURE

The central concept to the operation of the system is the structure
of the Function Menus accessed through the FFD; once these are
understood operation becomes simple.

Regular users of computers will be familiar with the concept of
structured menu layers. At each level there is a set of choices
which can be scrolled through (selected) until the required menu is
reached. When selected the FFD then displays the choice for the
next menu level. The function options available through each
menu choice are listed in Table 1.1 - Operating Functions.
Operational Menu choices together with the Function Menu
applicable are listed in Table 1.2 - Operational Menu Choices.

Note
The Functions available to the user are dependent on the range of
sensors fitted to the system. Details of the sensors required for
each function are fully explained in Part 3 - Operating Information.

2.6 ALARMS

2.6.1 Alarm Control

When a pre-set alarm parameter is reached, for example, the depth
reducing, the system raises an alarm automatically. In an alarm
condition, the lower display changes to highlight the cause of the
alarm, which flashes red and green alternatively until the Enter Key
is pressed twice. At which point all FFDs, with the exception of the
FFD on which Enter was pressed, return to normal. The audible
alarm, if fitted, is also silenced by this operation. After this, the lower
display continues to monitor the alarm condition. The alarm is still
active; if the alarm parameter is again exceeded the alarm will
flash/sound as necessary. The displayed alarm function remains on
the lower display until Page is pressed.

2.6.2 Alarm Types

The system incorporates the following types of alarm:

HI ALARM - This is generated if the value of a function
exceeds a pre-set level.

LO ALARM - This is generated if the value of a function
drops below a pre-set level.

SECTOR ALARM - This is generated when the value of a
function leaves the safe sector as shown in Fig 2.2.

Fig 2.2 - Sector Alarm

HB-0846-03

HS 2000 User Manual
Part 2 - Operating Information

For example, when the SECTOR alarm is turned on, the alarm
reference heading is the current compass heading. If the SECTOR
alarm is set at 40°, the sector value is the compass heading +/- 20°.
It is therefore important to switch off the SECTOR alarm before
carrying out a course alteration and switching the alarm on again
when settled on the new course heading.

Any alarm can be turned ON and OFF individually, or all alarms can
be turned OFF collectively.

2.6.3 Set Lo Alarm - Depth

(1) Select function which requires alarm facility, for
example, DEPTH.

(2) If the selected function is in the upper display, press
Scroll Down and scroll the lower display until ALARMS
appears, flashing. If the selected function is in the lower
display use Scroll Up.

(3) Press Enter, the text shows ALL OFF flashing.

(4) Use Scroll Up or Scroll Down, as appropriate, and
scroll through until the text shows LO ALARM flashing.

(5) Press Enter, the display shows the current LO ALARM
value.

(6) To change the LO value, press Enter, the value
flashes.

(7) Press Scroll Up or Scroll Down to increase or
decrease the value, as required. Press Enter to accept the
new value and turn the alarm ON.

(8) Press Page to return to the normal display.

To access the HI alarm, scroll through the text until HI ALARM
appears and press Enter to reveal current HI Alarm value. To
change the value, use the same procedure as used to change the
LO alarm value.

2.6.4 Switch Alarms - On/Off

To turn off an alarm (HI, LO or SECTOR), scroll through the menu
until the required item (for example, HI OFF) appears in the upper
display and press Enter.

To turn ON an alarm, scroll through until the required item (for
example, LO ON) appears in the upper display and press Enter.

2.7 TRIP FUNCTIONS

The HS 2000 System provides two trip functions Trip Log and Dead
Reckoning. The functions can be reset and restarted as required, for
example, for keeping a separate log of elapsed distance for a given
passage.

When any trip function is started, all other trip functions which have
been reset start simultaneously.

When a trip function is displayed, the two right hand characters show
the status of that function.

The letters MS (Minutes/Seconds) and NM (Nautical Miles)
indicate the function is running.

The letters RE denote RESET, where the function is zeroed
and waiting to be started.

The letters FR denote FROZEN, where the displayed value
is frozen but the function is still counting in the background.

2.7.1 Fast Reset

The HS 2000 System incorporates a Fast Reset feature for all trip
functions (Trip Log and Barometric Pressure Trend). Fast Reset can
be initiated either by operation of a Remote Push-Button (see
Paragraph 2.1.9) or by operation of the Enter Key on any FFD.

Note

If two trip functions are displayed simultaneously, the Fast Reset
facility will only reset the function shown in the upper display.

2.7.2 Reset Trip Log

(1) Display TRIP LOG in the upper display.

Note

Each time you reset the TRIP LOG the AVERAGE SPEED resets
and begins its calculation again. The control facility for the Dead
Reckoned functions works in the same way; the bearing and
distance are linked so that they start simultaneously.

2.8 LIGHTING CONTROL

The level of illumination at system displays is controlled by the
Power/Light Key. Use of this key normally controls all the HS 2000
System displays simultaneously. However, the level of illumination on
a single FFD can be controlled individually using the menu choice ­LOCAL LIGHTING.

2.8.1 Select Local Control

(1) Press and hold Scroll Up or Scroll Down until
LIGHTING appears in the text.

(2) Press Enter.

(3) Press Scroll Up until LOCAL is displayed.

(4) Press Enter again, the original page display appears.
Control of the FFD is now in local mode.

Successive operation of the On/Off Illumination Key now controls
the current display only. This will enable you to use very low lighting
at the chart table while maintaining the brightness up on deck.

2.8.2 Select System Control

(1) Press and hold Scroll Up or Scroll Down until
LIGHTING is displayed in the text.

(2) Press Enter and Scroll Up or Scroll Down to select
SYSTEM.
