Risk of damage/destruction through low temperatures
The supporting fluid in the gyrosphere container will start freezing at
temperatures below 0° C.
The NAVIGAT XMK 1 must no longer be operated when the ambient tem­perature at the gyrocompass’ location falls below - 10° C while the com­pass is in operation or when the ambient temperature falls below 0° C
while the gyrocompass is not in operation.
Always make sure, that the ambient temperature is higher than 0° C
respective 10° C. If this is not possible, the gyrosphere container with
gyrosphere must be removed from the NAVIGAT X MK 1 and transported
to a place with sufficient ambient temperature.
Make sure to remove the gyrosphere from the gyrosphere container if no
place with sufficient ambient temperature is available to eliminate dam­age from freezing supporting fluid. The removal is to be executed in a
service work procedure by authorized service personnel only.

Risk of damage through rotating masses
After power-down of the compass system, the gyroscopes need at least
45 minutes to stop rotating. Opening the container or draining off the
supporting fluid during rotating will damage the gyrosphere.
Wait at least 45 minutes after power-down of the compass system and
make sure, that the gyroscopes have stopped rotating before opening the
container or draining off the supporting fluid.

Risk of damage through inadequate cleaning solvents
Do not clean the compass housing with organic solvents, acetone or any
other substance which could damage or discolour plastic.
Use only soapy water or a mild detergent to clean the compass housing.

Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the cooling fan and cause over­heating of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full cooling fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the fan functionality to avoid overheating.

Risk of damage through unauthorized service
Any service and installation work on the gyrosphere is to be carried out
by authorized service personnel only.
Never undertake service or installation work if unskilled for the certain
procedure.

Risk of damage through unauthorized service
Only authorized service personnel is allowed to remove the gyrosphere
from the gyrosphere container.
Always keep to the mandatory safety requirements and the correct serv­ice work procedure to remove the gyrosphere from the gyrosphere con­tainer.

Risk of damage through unauthorized service
Only authorized service personnel is allowed to remove gyrocompass
system components from the compass housing.
Always keep to the mandatory safety requirements and the correct serv­ice work procedures to remove gyrocompass system components from
the compass housing.

Risk of damage to the gyrosphere
The gyrosphere is always to be transported in its carrying box in the orig­inal transport container.
Do not throw or drop the transport container.
The transport container is to be transported in an upright position only.

Risk of damage to the gyrosphere
Carry the carrying box containing the gyrosphere by hand only and han­dle it with extreme care.
Remove the gyroshpere from the carrying box only if required for imme­diate installation.

Risk of data loss through shutdown of the compass / power-off condition
After a shutdown of the compasses main and backup power supplies it
cannot be guaranteed that all menu settings remain stored unchanged.
Always check whether the shaft correction angle and alignment error cor­rection values are noted correctly in the setup tables, before switching­off the power supplies, see “Setup and Configuration Tables” on page A­1 Appendix.
Always make sure to separately note the shaft correction angle and align­ment error correction values before switching-down the compass for
maintenance or repair purposes.

Risk of defective gyrosphere caused by “GYRO FAILURE”
Should a “GYRO FAILURE” alarm occur during power-up, the compass
is not working properly.
De-energize the system and visually check the connections to the gyro­sphere, the follow-up step motor and the shaft encoder.
If the failure reoccurs when the compass is powered-up again, the instal­lation has not been carried out correctly or the gyrosphere is defective
and must be replaced.

Risk of defective gyrosphere
The gyrosphere may not be in operable working condition, if after a time
period of around 45 minutes after power-up the gyrosphere current has
not dropped below 320 mA.
If a visual inspection reveals no obvious cause of malfunction, the power­up cycle of the gyrosphere must be completely repeated.
If after a time period of around 45 minutes after the second power-up
cycle the gyrosphere current has still not dropped below 320 mA, the
gyrosphere may not be in operable working condition.
Contact the Sperry Marine Service for advice.

Risk of misleading gyrosphere data / operating values
The temperature and gyrosphere current values are indicated as reading
values at the CDU only.
Both values can be adjusted via correction values, which are set to neu­tral (= no correction) values by default.
Therefore the indicated values may deviate from real gyrosphere operat­ing values, which can only be measured at the required checkpoints by
authorized service personnel.

Risk of inadequate correction values
Any wrongful or not instructed adjustment of the temperature and gyro­sphere correction values will falsify a correct identification of the
NAVIGAT X MK 1 system‘s operating conditions.
Only authorized service personnel is allowed to change the temperature
and gyrosphere current correction values.
Never alter the correction values unless specifically instructed by Sperry
Marine.

Risk of inadequate testing / test values
The usage of any voltmeter NOT true RMS for testing will falsify the test
results.
The usage of a multimeter true RMS is absolutely mandatory.
Newer use a voltmeter not true RMS for testing purposes.

Risk of damage through inadequate operating conditions
Inadequate operating conditions such as e.g. ambient over temperature
or inadequate ventilation, can damage the gyrocompass and decrease
the system performance and the longevity of the system components.
Always keep to the recommended install and environmental conditions
to ensure trouble free operation and best performance of the gyrocom­pass. Always maintain adequate ventilation at install place.
Additional ventilation may become necessary to meet required ambient
environmental conditions for best performance and system longevity.

Risk of unstable/unreliable heading in polar waters
When operating the vessel in polar waters, the heading information of
the gyrocompass may become unstable/unreliable resulting in possible
deviation.
For safe steering in polar waters, the heading information of the gyro­compass may therefore NOT be used for navigation and heading infor­mation of a GNSS (Global Navigation Satellite System) compass be
preferred instead.

The definition of polar waters follows E190E IMO Guidelines for ships
operating in polar waters and is illustrated in
‘Polar Waters Definition” on page 1-9.

Risk of damage to the gyrosphere through shut-down
A shut down of the NAVIGAT X MK 1 system, while the vessel is navigat­ing, will damage the gyrosphere, as the gyrosphere is only self protected
against physical damage, as long as the system is running.
NEVER shut down the NAVIGAT X MK 1, while the vessel is navigating.
A shut down of the NAVIGAT X MK 1 system for good reason is only pos­sible when the ship is NOT navigating.

Sperry Marine requires to NOT shut down the NAVIGAT X MK 1 system
as long as the vessel is navigating, even when operating in polar waters
with possible unstable/unreliable heading.

Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the cooling fan and cause over­heating of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full cooling fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the fan functionality to avoid overheating.

A visual inspection of cables and connectors of the gyrocompass should
be carried out regularly to detect any signs of damage or deterioration.

This Operation, Installation and Service Manual 056343 applies only for
NAVIGAT X MK 1 systems with the new type master PCB and the PCB
transformer on the rear side.
For NAVIGAT X MK 1 systems with the old type master PCB and the PCB
transformer on the front side, only the Operation, Installation and Service
Manual 056310 is applicable.

In case a „Speed Invalid“ alarm is triggered while the vessel is not in
motion or moving very slowly (e.g. when manoeuvring in harbour), this
is often caused by fast currents of fairway water increasing the - 5.0 kn
minimum speed default value.
In this case, the minimum speed value must be adjusted accordingly.

Risk of damage/destruction during transport
The gyrosphere is always to be transported in its carrying box in the orig­inal transport container.
Do not throw or drop the transport container.
The transport container is to be transported in an upright position only.
Carry the carrying box containing the gyrosphere by hand only and han­dle it with extreme care. Remove the gyroshpere from the carrying box
only if required for immediate installation.

Risk of damage to NAVIGAT X MK 1gyrocompass system through
inadequate install and environmental conditions
Inadequate install and environmental conditions can damage the gyro­compass and decrease the system performance and the longevity of the
system components.
Always keep to the recommended install and environmental conditions
to ensure trouble free operation and best performance of the gyrocom­pass system.

Risk of erroneous heading accuracy caused by vibration / resonance
frequencies
The NAVIGAT X MK 1 gyrocompass is a highly sensitive instrument.
Resonance frequencies or vibrations caused by incorrect install position
or install and environmental conditions will badly influence the heading
accuracy.
Always keep to the recommended install and environmental conditions.
Never install the gyrocompass in or close the engine room or any posi­tion where reasonable vibration / resonance frequencies levels are
exceeded. Always make sure to minimise possible resonance frequen­cies or vibration causes at install place when installing the gyrocompass.

Risk of erroneous heading accuracy caused by electromagnetic
interference (EMC)
The NAVIGAT X MK 1 gyrocompass is a highly sensitive instrument.
Electromagnetic interference of other devices or their power lines will
badly influence the heading accuracy.
Always keep to the recommended minimal clearance requirements at
install position of the gyrocompass.
Never install other electronic equipment or high voltage power lines
close to or across the compass housing.
Always make sure to minimise possible electromagnetic interference of
other devices when installing the NAVIGAT X MK 1 gyrocompass.

Risk of inadequate testing / test values
The usage of any voltmeter NOT true RMS for testing will falsify the test
results.
The usage of a multimeter true RMS is absolutely mandatory.
Newer use a voltmeter not true RMS for testing purposes.

Risk of damage/destruction after power-down
After power-down of the gyrocompass system, it may take up to
45 minutes for the gyroscopes to stop rotating and the gyrosphere is
therefore extremely sensible against any movement. Should the gyro­sphere touch the wall of the container, the momentum of the rotating
gyroscopes will make it topple and damage the centre pin.
Avoid any movement of the gyrocompass system during power-down
time. Always be extremely careful in case the gyrosphere container must
be handled during power-down time.

Risk of damage of electrostatic-discharge-sensitive components
The NAVIGAT X MK 1 contains electrostatic sensitive components.
Electrostatic discharge may permanently damage components.
When servicing the NAVIGAT X MK 1, take considerable precautions to
prevent electrostatic discharge. Avoid touching any of the electronic cir­cuitry.

Risk of loss of parameter settings through software exchange
It cannot be guaranteed that parameter settings in the User and Setup
menus and the entries made in the Magnetic Compass Calibration table
are left intact when the software is exchanged.
Before exchanging the system software IC, record all parameter settings
to be able to re-enter them manually, if required.

Risk of malfunction through wrong wiring
Wrong wiring, especially as running wires from one side of the compass
housing to the other or across the master PCB will cause malfunction.
Always use the cable inlets on both sides of the compass housing for
accurate wiring and keep all wires running inside the housing as short as
possible.
Always avoid to run wires from one side of the compass housing across
to the other.

Risk of earth faults
Wrong wiring of the cable shields makes the cables act as antennas
resulting in earth faults.
Always make sure to correctly draw back the cable shields and fasten the
cables to avoid earth faults.

In case of earth faults, it is recommended to always check first the cable
wiring for correctly connected cable shields.

Risk of ROT filter malfunction
The selected ROT filter setting in the manual settings menu needs addi­tional activation to gain ROT filter functionality
For activating the ROT filter setting in the service setup 1, it is mandatory
to pre-install a wire link at the master PCB TB2 19/20.

To make sure, that the ROT damping time constant setting for the ana­logue ROT output becomes effective, check if the mandatory wire link
between the master PCB TB2 19/20 is correctly installed.

Risk of damage through aggressive cleaning agents
Do not clean the compass with organic solvents, acetone or any other
substance which could damage or discolour plastic.
Only use water and soap or a mild detergent to clean the compass.

Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the fan and cause overheating
of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the fan functionality to avoid overheating.

Risk of defective gyrosphere
The gyrosphere may not be in operable working condition, if after a time
period of around 45 minutes after power-up the gyrosphere current has
not dropped below 320 mA.
If a visual inspection reveals no obvious cause of malfunction, the power­up cycle of the gyrosphere must be completely repeated.
If after a time period of around 45 minutes after the second power-up
cycle the gyrosphere current has still not dropped below 320 mA, the
gyrosphere may not be in operable working condition.
Contact the Sperry Marine Service for advice.

The NAVIGAT X MK 1 is a digital gyrocompass system for the maritime
navigation of vessels and must be operated only from appropriately
trained and educated personnel familiar with all mandatory safety and
operating procedures.

The NAVIGAT XMK 1 provides North-speed error corrected true heading
data as well as rate of turn (ROT) data for the navigation of maritime
vessels.

The NAVIGAT X MK 1 can operate as a standalone system or as part of a
multi gyrocompass system environment (Heading Management Sys­tem, HMS).

kзн=fенЙеЗЙЗ=rлЙ

The NAVIGAT X MK 1 and/or the provided true heading and ROT data of
the NAVIGAT X MK 1 are not allowed to be used for the navigation of
inland water vessels and river boats. Any exception to this restriction
must be regulated by specific certification of an entitled organisation or
administration, for further details see certification information under
”Design and Main Features” on page 1-6 and ”Marine Equipment Direc­tive EC Declaration of Conformity” on page 1-17.

Although the NAVIGAT X MK 1 is a highly accurate system for providing
true heading and ROT data, operators must not rely on it solely as the
only heading source. The plausibility of the NAVIGAT X MK 1 heading
and ROT data and the speed and position input data (as secondary data)
must always be confirmed against all other available aids to navigation.

Since the NAVIGAT X MK 1 system can additionally be used for display­ing secondary navigation data (speed and position input data) gener­ated from other connected devices, the operator must not take
displayed secondary data for granted and is obliged to confirm the
validity of secondary data independently.

When navigating in polar waters (according to E190E IMO Guidelines
definition), the heading information of the gyrocompass may become
unstable/unreliable, due to physical principles, resulting in possible
deviation. For safe steering of the vessel in polar waters, the heading
information of the gyrocompass may therefore not be used and heading
information of a GNSS (Global Navigation Satellite System) compass be
preferred instead.

60945(2002), IEC 62288(2008) and IEC 61162 series.

The NAVIGAT X MK 1 HSC-version Type 4914 CC (stock no. 74811) with a
specially selected gyrosphere complies with the following specified
standards as gyrocompass for high speed craft (HSC):
IMO resolutions A.821(19), A.694(17), MSC.36(63), MSC.97(73),
MSC.191(79), ISO 16328(2001), IEC 60945(2002), IEC 62288 (2008) and
IEC 61162 series.

The NAVIGAT X MK 1 Type 4914 CA and NAVIGAT XMK 1 HSC-version
Type 4914 CC comply with the following specified standards as rate of
turn indicator (ROTI):
IMO resolutions A.526(13), A.694(17), MSC.36(63), MSC.97(73),
MSC.191(79), ISO 20672(2007), IEC 60945(2002), IEC 62288(2008) and IEC
61162 series.

The NAVIGAT X MK 1 has been type approved by the
Russian River Register (RRR) for the purpose of provision of navigation
safety of inland navigation and river-sea going vessels and has been
assigned certificate 190-06-3.1.1.

For further details see “Marine Equipment Directive EC Declaration of
Conformity” on page 1-17.

The single unit design with a polyurethane hard foam housing allows
the gyrocompass to be installed on any bridge. If required, the operating
unit may be installed at a location remote from the compass or an addi­tional remote operating unit may be used.

The unique method of supporting the gyrosphere by means of mere
buoyancy ensures North stabilisation during short power failures, e.g.,
after a three minute loss of power, no more than two degrees of devia­tion may be expected. Once power has been restored, the gyrocompass
will return quickly to the correct heading. The combined effects of the
twin rotors and the liquid damping system virtually eliminate latitude
error.

Heading is measured as a 13-bit absolute value with a digital shaft
encoder. The high-speed follow-up system (follow-up speed up to
100°/s) ensures that accurate heading and rate of turn data is provided
under all operating conditions. Integrated monitoring of the supply pow­ers, gyroscope current and the follow-up system ensure secure and
trouble free operation.

The north-seeking element used in the NAVIGAT X MK 1 system is the
gyrosphere, a hermetically sealed unit with a funnel-shaped recess,
reaching from the outer skin down to its centre.

Inside the gyrosphere, two mechanically linked gyroscopes are
mounted with their spin axes horizontal in a carrying frame. The gyro­scopes are allowed to turn around the vertical, but torsion bands effect a
defined rest position, while a mechanical linkage ensures that the result­ant spin vector of the gyros remains stationary relative to the gyro­sphere. This twin gyro arrangement eliminates intercardinal roll error.
Once the gyros have run up to speed, their resultant spin vector, and
with it the gyrosphere, settles in the direction of true North.

cбЦмкЙ=NJUW

dукзлйЬЙкЙ

The top of the gyrosphere contains an annular damping trough, half
filled with a viscous fluid. The fluid damps azimuthal oscillations of the
gyroscope system. The oscillation period is tuned to the Schuler period
of 84.4 minutes, so that heading errors during horizontal acceleration
due to changes in speed and/or direction are prevented.

The gyrosphere floats in a supporting fluid inside the gyrosphere con­tainer. Because the buoyancy of the gyrosphere is a little greater than its
weight, a bearing cup at the bottom of the recess is pressed against the
centering pin and keeps the gyrosphere exactly centered in the con­tainer.

In order to make the gyroscope system pendulous, that is, to provide the
gravity controlling moment, the gyrosphere is designed so that its cen­tre of gravity lies slightly below the centre of buoyancy.

The gyroscopes are in fact squirrel-cage induction motors, which attain
a speed of nearly 20000 rpm at a voltage of 100 VAC @ 337 Hz.
In the Mod. 10/3 container, their supply power is applied through the
electrolytically conducting supporting fluid, via the top and bottom con­tacts. In the Mod. 10/2 and Mod. 7/2 containers, the power is applied via
the centering pin and the bottom contacts.

A follow-up control circuit keeps the container aligned with the gyro­sphere at all times, thus heading can be derived from the container’s ori­entation.

MRSPQPLc k^sfd^q u jh N

kçíÉ

While systems with the Mod. 10/3 container employ an optical pick off to
provide the follow-up control signal, systems with the Mod. 10/2 and
Mod. 7/2 containers use a resistance bridge circuit, formed by the con­ducting paths from the contact pins in the container, through the sup­porting fluid and to the equator contact of the gyrosphere.

The Mod. 7/2 container and the Mod. 10/2 container (if not refitted for
mercury free operation) use mercury for the resistance bridge circuit.
Only specially trained personnel is allowed to take care with all handling
of mercury and special handling procedures must be maintained.
Always keep to the current issue of the mercury handling procedures of
Sperry Marine Northrop Grumman, stock no. 026150-0000-000.

Risk of unstable/unreliable heading in polar waters
When operating the vessel in polar waters, the heading information of
the gyrocompass may become unstable/unreliable resulting in possible
deviation.
For safe steering in polar waters, the heading information of the gyro­compass may therefore NOT be used for navigation and heading infor­mation of a GNSS (Global Navigation Satellite System) compass be
preferred instead.

Risk of damage to the gyrosphere through shut-down
A shut down of the NAVIGAT X MK 1 system, while the vessel is navigat­ing, will damage the gyrosphere, as the gyrosphere is only self protected
against physical damage, as long as the system is running.
NEVER shut down the NAVIGAT X MK 1, while the vessel is navigating.
A shut down of the NAVIGAT XMK 1 system for good reason is only pos­sible when the ship is NOT navigating.

Correlation of heading error and latitude (0.4° x sec. lat.)

As shown in figure 1-11, the heading error is increasing with higher lati­tude (correlation of dynamic heading error 0,4° x secans of latitude).

Due to physical principles, this correlation is a general system imma­nent attribute of any spinning mass gyrocompass as a north seeking
system.

As a result, the heading information of the gyrocompass may become
unstable/unreliable resulting in possible deviation, when navigating in
polar waters. For safe steering of the vessel in polar waters, the heading
information of the gyrocompass may therefore not be used and heading
information of a GNSS compass be preferred instead.

Sperry Marine requires to NOT shut down the NAVIGAT X MK 1 system
as long as the vessel is navigating, even when operating in polar waters
with possible unstable/unreliable heading.

As a standalone system, the NAVIGAT X MK 1 provides North-speed
error corrected true heading as well as rate of turn data.

If a magnetic compass with fluxgate sensor, type 4863, or an electronic
compass is installed, the NAVIGAT X MK 1 applies magnetic variation
and distributes magnetic compass heading data to external equipment
(Transmitting Magnet Compass, TMC function).

The heading difference alarm function permits to monitor the difference
between the gyrocompass and magnetic compass heading sources.

In case of failure of the gyrocompass, the magnetic compass heading
source may be activated to provide an emergency heading reference for
repeaters and other peripheral equipment.

The system shown in figure 1-13 below is the standard configuration for
a dual NAVIGAT X MK 1 gyrocompass system.
In addition to the two NAVIGAT XMK 1 gyrocompasses, this system
comprises the NAVITWIN IV heading management system (HMS) and
the Switch-Over Unit Type 4932.

By selecting the active heading source at the NAVITWIN IV, the operator
determines which gyrocompasses’ data is distributed via the Switch­Over Unit to external equipment, such as heading control systems,
RADAR, compass repeaters etc.

The NAVITWIN’s heading diff. alarm function permits to monitor the dif­ference between any two of the available heading sources. The off head­ing alarm function permits to monitor the difference between the actual
heading from the active source and the set heading order, as received
from a heading control system or entered manually.

Alarms generated locally by a NAVIGAT gyrocompass are indicated and
may be acknowledged at the NAVITWIN IV. In turn, the NAVITWIN IV
transmits system-wide operational settings and setup parameters to the
NAVIGAT gyrocompasses. The available heading sources, the current
source selection and the heading difference alarm threshold (hdg. diff.
threshold) are also indicated at both gyrocompasses.
If a magnetic compass heading source is installed, the NAVITWIN
applies magnetic variation and distributes the data to external equip­ment (TMC function). In case of failure of the gyrocompasses, the mag­netic compass heading source may be activated to provide an
emergency heading reference for repeaters and other peripheral equip­ment.
