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.

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.

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.
lйЙк~нбеЦ=mкбеЕбйдЙNJT
Page 24
MRSPQPLck^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.

The permitted ambient temperature for the operation of the gyrocompass system is between - 10° C to + 55° C.
The recommended ambient temperature for highest system longevity
for the operation of the gyrocompass system is around 20° C.
Risk of damage/destruction through low temperatures
The supporting fluid in the gyrosphere container will start freezing at
temperatures below 0° C.
The NAVIGAT X MK 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.
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 compass is not in operation, the gyrosphere container must be removed from the compass housing and
stored in a place where the ambient temperature will not fall below 0° C.
Always be aware, that in case no storage place is available where the
ambient temperature will not fall below 0° C, the gyrosphere must be
removed by authorized service personnel from the gyrosphere container to prevent possible damage by frozen supporting fluid. see
“Removing the Gyrosphere Container from the Compass Housing” on
page 5-3 for details.
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 ineffective manual ROT damping settings
The selected ROT damping time constant for the analogue ROT output in
the manual settings menu needs additional activation to become effective by means of a wire link installed 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.
Sets the ROT damping time constant value for the analogue rate of turn
output. The larger the time constant, the less short-time fluctuations will
be present in the analogue rate of turn output voltage.
Value:MKM=Ó=NMKM ëÉÅ
Typical values are generally between 2 to 4 sec. (only effective if wire link TB2 19/20 at the master PCB is installed)
Following IMO requirements, the ROT damping time constant value for
the analogue rate of turn output can be selected between 0.0 to 10.0 sec.
All selected values above 10.0 sec will not be accepted by the menu and
„ERR“ is displayed for showing that the selected value is not valid.

The NAVIGAT X MK 1 requires no scheduled maintenance procedures
to be carried out by shipboard personnel or service personnel.
A visual inspection of cables and connectors of the gyrocompass should
be carried out regularly to detect any signs of damage or deterioration.
`дЙ~ебеЦ=зС=`згй~лл=eзмлбеЦ
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.
The display front plate and the gyrocompass housing should be kept
clean by using only water and soap or a mild detergent.
A visual inspection of cables and connectors of the gyrocompass should
be carried out regularly to detect any signs of damage or deterioration.
`äÉ~åáåÖ=çÑ=^áê=fåäÉí=dêáää
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.
Sperry Marine recommends to regularly clean the air inlet grill of the fan
and to check the functionality of the fan with every gyrosphere maintenance interval latest, as this is mandatory to avoid overheating of the
gyrocompass.
An immediate exchange of the NAVIGAT X MK 1 fan is mandatory in
case the fan is found in improper condition.
A default exchange of the fan is recommended in a three years interval.

Risk of damage through misusage
Scheduled maintenance or service work on the gyrosphere is to be carried out by authorized service personnel only.
The gyrosphere and the gyrosphere container are the only components
of the NAVIGAT X MK 1 which require regular maintenance.
For installation and service procedures of the gyrosphere and gyrosphere container, the following separate Installation, Maintenance and
Service Procedures, delivered with the gyrosphere, apply:
- 04911-0125-001, for gyrosphere type 2, gyrosphere container mod. 7/2
- 04911-0125-002, for gyrosphere type 2, gyrosphere container mod. 10/2
- 05000-0125-001, for gyrosphere type 3, gyrosphere container mod. 10/3
- 05000-0125-002, for gyrosphere type 3, gyrosphere container mod. 10/3
with the NAVIGAT X MK 1 in DP vessel application.
NUJjзенЬ=j~бенЙе~еЕЙ
Sperry Marine recommends to have a regular gyrosphere maintenance
carried out by authorized service personnel every 18 months.
The recommended 18-month maintenance comprises the removal of
the gyrosphere, cleaning and inspection of the gyrosphere, maintenance of the gyrosphere container and the re-installation of the gyrosphere using fresh supporting fluid. If necessary, the centering pin is to
be replaced.
Sperry Marine recommends to have the optical pick-off PCBs exchanged
by default every second 18-month maintenance interval (= 36 months).
The NAVIGAT X MK 1 is counting the system operating hours automatically until a maximum level (18 months) is reached. When the maximum
level of operating hours is reached, the following message is displayed
automatically:
RECOMMENDED ANNUAL MAINTENANCE DUE!
(see manual)
F1 CONFIRM
This message indicates no malfunction but is intended to remind the
operator that the recommended maintenance interval has been
exceeded.
When the reminder message is acknowledged with Shift+F1, the main
menu is displayed.
During gyrosphere maintenance, the gyrosphere operation time counter
will be reset.

After having reached the maximum level of operating hours, the
reminder message will also become displayed each time the gyrocompass is powered up again.
When the reminder message is acknowledged with Shift+F1, the gyrocompass will power-up and commence normal operation.
dукзлйЬЙкЙ=oЙйд~ЕЙгЙен=L=cбоЙJvЙ~к=j~бенЙе~еЕЙ
To ensure continued trouble free operation and to minimize the risk of
failure, Sperry Marine recommends regular maintenance every five
years.
The replacement of a defective gyrosphere and the recommended fiveyear maintenance both comprise the removal of the existing gyrosphere, maintenance of the gyrosphere container and the installation of
a new gyrosphere using fresh supporting fluid.
The centering pin is to be replaced routinely during the five-year maintenance and during the replacement of a defective gyroshpere, if necessary. Gyrosphere and the centering pin are to be exchanged by
authorized service personnel.
The five-year exchange interval for the gyrosphere and is to be regarded
as a recommendation only. Under normal conditions, the gyrosphere is
able to operate flawlessly over a considerably longer period of time.
As long as gyrosphere is running flawlessly, the customer may decide to
keep it in service and have only the regular 18-month maintenances carried out.

Risk of damage/destruction through low temperatures
The supporting fluid in the gyrosphere container will start freezing at
temperatures below 0° C.
The NAVIGAT X MK 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 the
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.
The permitted ambient temperature for the operation of the gyrocompass system is from - 10° C to + 55° C.
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 compass is not in operation, the gyrosphere container must be removed from the compass housing and
stored in a place where the ambient temperature will not fall below 0° C.
Removal and storage of the container as a whole (with the gyrosphere
installed), as well as later re-installation of the container may be carried
out by shipboard personnel; see “Removing the Gyrosphere Container
from the Compass Housing” on page 5-3 and “Installing the Gyrosphere
Container in the Compass Housing” on page 6 for details.
Always be aware, that in case no storage place is available where the
ambient temperature will not fall below 0° C, the gyrosphere must be
removed by authorized service personnel from the gyrosphere container to prevent possible damage by frozen supporting fluid.
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.

dукзлйЬЙкЙ=a~г~ЦЙ=нЬкзмЦЬ=pЬмн=aзпе
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.
As long as the vessel is navigating, Sperry marine requires the
NAVIGAT X MK 1 system not to be shut down, to keep the gyrosphere
always self protected against possible physical damage, caused by vessel movement.
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.
If a shut down of the NAVIGAT XMK 1 system is intended for good reason, the vessel must stop navigating before the shut down and removal,
storage and re-installation of the container from the compass housing
and the gyrosphere from the container, must be carried out by authorized service personnel only to protect the gyrosphere against possible
damage.
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.
For installation and service procedures of the gyrosphere and gyrosphere container, the following separate Installation, Maintenance and
Service Procedures, delivered with the gyrosphere, apply:
- 04911-0125-001, for gyrosphere type 2, gyrosphere container mod. 7/2

- 05000-0125-002, for gyrosphere type 3, gyrosphere container mod. 10/3
with the NAVIGAT X MK 1 in DP vessel application.
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 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/destruction through transport/wrong storing
When the container with the gyrosphere installed is temporarily stored
away, pack it into its original transport box or another suitable outer
package.
Always make sure that:
- the container is stored in an upright position,
- the temperature at the storage location cannot fall below 0°C,
- the container is not moved, tilted or subjected to shock.
1. Check and note the shaft encoder correction angle and alignment
error correction values. Double check whether the shaft encoder correction angle and alignment error correction values are correctly
noted in the setup tables.
2. Switch off the compasses main and backup power supplies and take
all the necessary precautions to make sure that the compasses main
and backup power supplies remain switched off during any removal
and installation procedures.
3. Unscrew the 5 mm hex-head screws of the compass housing door

12. Put the door in front of the housing, so that the keys can be operated. If the CDU cable has been disconnected during gyrosphere
installation, reconnect it.
⇒ The gyrocompass is now ready to be put into operation.
Leave the housing door open to observe the settling of the gyrosphere.
Proceed with the ‘Power-up Function Test” as described below.
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.
To verify the correct operation of an installed or re-installed gyrosphere,
the settling behaviour of the compass is to be observed, with the front
door of the compass housing opened.
For a present operating voltage of 100 VAC on the master PCB, 105 VAC
true RMS are necessary.
The setting of true RMS can be adjusted via the potentiometer on the
master PCB. For details see figure 5-3 on page 5-12.
dукзлйЬЙкЙ=`мккЙен=mкЙдбгбе~кбЙл
The value of the gyrosphere current is decreasing continuously and is a
key indicator for a successful gyrosphere settling at a given point of time
during the power-up function test.
The gyrosphere current value in the Service Setup 2 (code 610), indicated at the CDU, is a reading value only and may deviate from the true
operating gyrosphere current value (measured true RMS).
The true operating value of the gyrosphere current can only be measured (true RMS) at the 1 Ω gyro current test resistor (R103) on the master PCB. All gyrosphere current details are commented within the
power-up function test.
The AC-voltage in mV across the test resistor (R103) equals the gyrosphere current in mA.
⇒ Figure 5-1 on page 5-10 shows the location of the 1 Ω gyro current
The 1 Ω gyro current test resistor (R103) is located at the left
side of the master PCB close
beneath the J4 connector and
TB8.

1. Power up the compass system.
A startup screen is shown and a system
test sequence is executed.
When the system test has been passed,
the compass enters normal operational
mode. The display shows the heading
data from the available compasses and
the heading difference alarm threshold.
–In case of a first-time installation where the basic configuration
has not been carried out yet, alarms will be given at this point.
Alarms caused by missing input data or an incomplete system
configuration may be safely acknowledged to continue with the
power-up function test.
RJNMmзпЙкJмй=cмеЕнбзе=qЙлн
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.

2. Observe the settling of the gyrosphere:
–The gyro motors will create a spinning noise which slowly but
constantly rises in pitch until the rotors reach their final speed.
–The follow-up system will turn the container quickly around the
gyrosphere until the optical pick off “locks” onto the motion of
the gyrosphere. From then on, the container will engage in a
slow oscillatory motion around the vertical, following the motion
of the gyrosphere.
–The amplitude and speed of this motion will steadily decrease
until the gyrosphere finally settles.
3. During the settling phase, periodically call up the gyrosphere data
sub-menu from the Service Setup 2 (code 610), to observe the gyrosphere current, see ”GYROSPHERE DATA” on page 8-22 in the
‘Service Setup 2 – Parameters´ submenu.
Directly after power-up, the gyrosphere current should not exceed
550 mA. The current will gradually
fall while the gyrosphere settles.
20 minutes after power-up a considerable fall of the gyrosphere current
should have occurred.
4. Check 20 minutes after power-up wether a considerable fall of the
gyrosphere current has occurred.
Within around 45 minutes after
power-up, the gyrosphere current
should have dropped below 320 mA.
5. Check if after around 45 minutes after power-up whether the gyrosphere current has dropped below 320 mA.
The true operating value of the gyrosphere current can only be measured
(true RMS) at the 1 Ω gyro current test resistor (R103) on the master PCB,
location shown in figure 5-1 on page 5-10.
6. If after around 45 minutes after the power-up, a gyrosphere current
above 320 mA is still displayed in the gyrosphere data sub-menu,
the value must be reconfirmed:
–Measure the gyrosphere current directly at the 1 Ω gyro current
test resistor (R103) on the master PCB, location of the test resistor (R103) shown in figure 5-1 on page 5-10.
mзпЙкJмй=cмеЕнбзе=qЙлнRJNN
The AC-voltage in mV across the test resistor (R103) equals the gyrosphere current in mA.
7. In case the reconfirmed value for the gyrosphere current, directly
measured (true RMS) at the 1 Ω gyro current test resistor (R103) on
the master PCB is in contrast under 320 mA, the gyrosphere current

gain factor settings in the Technical Pages (code 140) need to
become checked and adjusted:
–Follow the instructions in ”CORRECTION VALUES” on page 8-26
of the ‘Factory Settings Menu (Technical Pages)´ to match both
gyrosphere current values.
8. In case the reconfirmed value for the gyrosphere current, directly
measured (true RMS) at the 1 Ω gyro current test resistor (R103) on
the master PCB, is as well above 320 mA, the VAC true RMS value
needs to become adjusted:
For a present operating voltage of 100 VAC on the master PCB, 105 VAC
true RMS are necessary.

PCB with a trimmer adjustment
tool to set 105 VAC true RMS.
⇒ Be careful not to damage the
potentiometer (R36).
A regular screwdriver is not recommended for the adjustment of the

master PCB to check whether
105 VAC true RMS are set.
11. Repeat steps 8 – 10 if necessary
until 105 VAC true RMS are set.
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.
⇒ If the current is still above 320 mA, the gyrosphere may not be in
operable working condition.
12. Proceed with a visual inspection of the gyrosphere, to search any
obvious cause for malfunction, see “Gyrosphere Maintenance” in
the Installation, Maintenance and Service Procedures, 05000-0125-01
for details.

13. If a visual inspection reveals no obvious cause for malfunction,
repeat the complete power-up procedure and check again if after
around 45 minutes after the second power-up cycle the gyrosphere
current has dropped below 320 mA.
⇒ If after around 45 minutes after the second power-up cycle the cur-
rent is still above 320 mA, and no other obvious cause of malfunction is found, the gyrosphere may not be in operable working
condition:
–Contact the Sperry Marine Service for advice.
⇒ If after around 45 minutes after the second power-up cycle the gyro-
sphere current has dropped below 320 mA, the gyrosphere is in in
operable working condition.
14. Note the exact gyrosphere current value in the setup tables.
15. After a settling time of at least 4 hours, verify that the gyrocompass
has settled to the correct heading.
The 4 hours settling time for the alignment is only mandatory in case of
a first time installation of the NAVIGAT X MK 1.
To verify the gyrocompass’ heading, the actual true heading of the vessel
should be known with an accuracy of ± 0.1°.
–Check whether the setting of the shaft encoder correction value
in the Service Setup 1 of manual 056343 matches with the value
indicated on the baseplate.
–In case of a first time installation, check that the heading shows
the correct value approximately, taking into account any existing
misalignment of the gyrocompass. Then, set the alignment error
correction value in the Service Setup 1 as required, see “Alignment Error Correction” of manual 056343 for details. After the
alignment error correction value has been set, the gyrocompass
is to display the vessel's true heading with an accuracy of ± 0.5°.
–In case of maintenance or replacement of the gyrosphere, the
displayed heading should now already be accurate within ± 1.0°.
If necessary, adjust the stored alignment error correction value,
so that the gyrocompass displays the vessel's true heading with
an accuracy of ± 0.5°, see “Storing the magnetic compass heading calibration table” of manual 056343 for details.
16. In case of a regular maintenance, or if a defective gyrosphere has
been replaced, a special service setup menu must now be called up
to reset the gyrosphere operation time counter.
The access code for the setup menu to reset the gyrosphere operation
time counter is disclosed to authorized service personnel only and is not
described in this service procedures.

The compact, space saving and low weight single unit design of the
NAVIGAT X MK 1 gyrocompass allows it to become installed at virtually
any location on board and on any bridge.
However, certain recommendations regarding environmental and
installing conditions exist, to enable best performance of the
NAVIGAT X MK 1 system; for the required environmental conditions, see
”General Safety Information for Service Personnel” and ”Environmental
Requirements” on page 1-13 for details.

The gyrocompass must be installed on a stable, level foundation.
In the horizontal plane, a maximum tilt of the compass housing relative
to the vessel´s X and Y axes of ± 3° is accepted.
The compass housing may be installed amidship, port or starboard. An
installing position midships respectively near to keel line is always preferable if possible.
The compass housing may be installed forward, aftwards or midships.
An installing position midships respectively near to the Center of Gravity (CoG) is always preferable if possible.
sЙенбд~нбзе=L=qЙгйЙк~нмкЙ
At the installing location of the compass, adequate ventilation must be
ensured. Air conditioning at installing location may be advisable to
ensure operation of the gyrocompass within ambient temperature range
/ recommended operational temperature for highest system longevity,
see also ”Temperature Conditions” on page 1-13.
bдЙЕнкзг~ЦеЙнбЕ=fенЙкСЙкЙеЕЙ
The gyrocompass is a highly precise electronic device and accuracies
will suffer in case of electromagnetic interference of other electrical
devices. All electromagnetic interference clearances must therefore
always be followed accurately to ensure trouble free operation of the
NAVIGAT X MK 1 system, see also ”Electromagnetic Compatibility
(EMC) / Electromagnetic Interference” on page 1-14 for details.

The gyrocompass is designed to work trouble free in Area A classified
locations according to Germanischer Lloyd vibration level classification,
see also ”Vibration” on page 1-14 for details.
The gyrocompass will show best operational performance if minimal
vibration levels are kept at place of installation.
Installing the gyrocompass in the engine room is not recommended and
should always be avoided if possible, as engine rooms are usually classified as Area B location, according to Germanischer Lloyd vibration
level classification.
An installing position directly on the vessel´s deck structure is always
preferable to minimise possible vibration levels.

fелн~ддбеЦ=нЬЙ=`згй~лл=eзмлбеЦ
For the installation of the gyrocompass all installing recommendations
and environmental requirements are to be followed, see “Environmental Requirements” on page 1-13 and ”Installing Recommendations” on
page 7-1 for details.
The compass housing is to be attached to a level surface, e.g. a floor or
console base by means of six M10 bolts or welding studs (to be supplied
by the shipyard). Sufficient space around the gyrocompass for the housing to be opened and maintenance work to be carried out must be
ensured. For the amount of space required, the attachment points and
the position of the cable inlets, refer to dimension drawing 4914-0112-02
in the appendix.
In the horizontal plane, the compass may be installed at any angle with
respect to the vessel‘s longitudinal axis and the alignment error (i.e. the
angle between the compass‘ and the vessel‘s longitudinal axis) is corrected electronically by setting the alignment error correction value in
the Service Setup 1, see “Configuration Menu - Service Setup 1” on
page 8-1 for details.
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.

The NAVIGAT X MK 1 main power supply transformer in the compass
housing is delivered pre wired for 230 VAC power supply with a wire
link connecting the transformer terminals 5 to 6, as shown in Figure 7-1.
If the system is required to operate on 115 VAC power supply, wire links
must be installed to link the transformer terminals 4 to 6 and 5 to 7.
To gain access to the main power supply transformer, the master PCB
and the baseplate must be temporarily removed from the compass
housing, see “Removing System Components from the Compass” on
page 6-1 for details.
Figure 7-1 shows the default wire link set for the 230 VAC power supply.
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.
Wire up the system according to the standard connection diagrams and
other relevant documents provided in the appendix.
If installation-specific connection diagrams have been provided for a
given system, these supersede any connection information contained in
standard connection diagrams.
Ship's cables are directly connected to screw-down terminals on the
master PCB.
Insert the ship's cables through the inlets at the sides of the compass
housing. Remove the outer cable covers, draw back the cable shields
and fasten the cables with clamps or tie-wraps to the threaded studs of
the inlet plates. Refer to dimension drawing 4914-0112-02 in the appendix.
Route the wires connecting to TB1 – TB4 through the inlets on the left
hand side of the housing.
Route the wires connecting to TB5 – TB7 through the inlets on the right
hand side.

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.
When the compass housing has been mounted and the system is wired
up so far that supply power is available, procedures should continue
with the installation of the gyrosphere into the gyrosphere container
and the mounting of the assembled container in the compass.
Alternatively, the installer may wire up the system completely and carry
out the initial system configuration before the gyrosphere is installed.
For installation and service procedures of the gyrosphere and gyrosphere container, the following separate Installation, Maintenance and
Service Procedures, delivered with the gyrosphere, apply:

To make the system fully functional, the configuration parameters need
to be set to the required values in the Service Setup 1, see “Configuration Menu - Service Setup 1” on page 8-1.
Additionally, the applicable standard operational settings should be
entered in the Manual Settings menu.
If a magnetic compass heading source is connected to the
NAVIGAT X MK 1 system, the magnetic compass calibration procedure
should be carried out during a sea trial, as described under ”Magnetic
Compass Calibration” on page 7-10.
1. Check that the wiring has been carried out completely. All devices
connected to data or signal in- and outputs should be operative.
2. Energize the system at the vessel's switch and fuse unit.
A startup message is displayed and the initial self test is executed.
If the initial system configuration is carried out before the installation of
the gyrosphere, the system will raise a „gyro failure“ alarm at power-up.
The alarm may be safely acknowledged at this point to continue with the
initial configuration.
3. Go to the ”Configuration Menu - Service Setup 1” on page 8-1.
4. Select the required system type and heading reference selection settings.
5. In dual or triple gyro systems, assign the required compass ID.
6. Select the required data formats for all devices connected to the data
inputs. In G or GG type systems, disable the magnetic compass
heading input, in G or GM type systems, disable the ext. gyro input.
7. Select the required data output formats and IEC 61162/NMEA protocol standard setting.
8. Check that the min./max. limits for the speed filter are well outside
the possible range of the vessel’s operating speed. In high-speed
craft, the max. speed value will have to be increased.
9. If required, set the parameters for the analogue rate of turn output,
the status in- and outputs and the rudder angle feedback inputs.

Risk of inaccurate alignment error correction
The compass must have been in continuous operation for at least 4 hours
before the alignment error can be determined accurately.
If bearing repeaters are used to determine the true heading, these must
be properly aligned to the vessel's fore-and-aft axis.
In order to obtain correct heading data, the existing alignment error (the
angular difference between the compass orientation and the vessel's
fore-and-aft axis) must be determined and the required correction
applied. Alignment error is 0° if the sides of the compass housing run
exactly parallel to the vessel‘s longitudinal axis and the back of the
housing points dead ahead. The alignment error correction is carried
out electronically by setting the correction value in the Service Setup 1.
qз=Е~кку=змн=нЬЙ=~дбЦегЙен=Йккзк=ЕзккЙЕнбзеW
1. Determine the existing alignment error by comparing the compass
heading with the vessel's true heading. The true heading must be
known to an accuracy of at least 0.5°.
2. Go to the Service Setup 1 and select the align error correction submenu, see “Configuration Menu - Service Setup 1” on page 8-1 for
details.
3. Enter the required correction
value.
⇒ The correction value equals the
alignment error with the sign
reversed.

The vessel’s true heading is
123.0°,
the compass displays 123.4°,
the alignment error is therefore
0.4°,
thus, the required correction
value is - 0.4°.
After accurate correction of the alignment error, the compass is to display the vessel's true heading with an accuracy of at least 0.5°.

Risk of inaccurate magnetic compass calibration
The magnetic compass heading calibration corrects deviations due to the
combined effects of the magnetic environment, the particular sensor
being used and the receiving circuitry on the master PCB.
Therefore, a new calibration must always be carried out when:
- the steering magnetic compass is exchanged or newly adjusted,
- the magnetic compass heading sensor is exchanged and,
- when the master PCB is exchanged, in case a fluxgate sensor is used.
Never use a true heading source, e.g. a gyrocompass, as the calibration
reference.
Never attempt to correct residual deviations of a properly adjusted magnetic compass by means of the calibration table.
Ideally, the magnetic compass heading displayed at the
NAVIGAT X MK 1 would exactly match the indication of the steering
magnetic compass (at a given mag. variation of 0.0°).
In practice, however, deviations will occur between the steering magnetic compass heading and the heading data transmitted by a fluxgate
sensor of a magnetic compass or an electronic compass, as displayed at
the NAVIGAT X MK 1.
The NAVIGAT X MK 1 automatically corrects such deviations if a calibration table has been stored and calibration is activated in the User Setup.
The Magnetic Compass Calibration Table shall only be switched on for
automatic magnetic compass heading correction in case a magnetic
compass is indeed connected to the NAVIGAT X MK 1 system via a fluxgate sensor.
If magnetic compass heading is received from an already calibrated
source, such as a NAVITWIN, NAVIPILOT or a self-calibrating electronic
compass, magnetic compass calibration at the NAVIGAT X MK 1 is not
required and must be disabled.
`~дбДк~нбзе=mкзЕЙЗмкЙ=lоЙкобЙп
Risk of inaccurate magnetic compass calibration
The magnetic compass used as the calibration reference must be properly installed and adjusted.
The procedure should be carried out in calm seas only.
The magnetic compass calibration is a two-step procedure:
•At first, the existing deviations between the indication of the steering
magnetic compass and the magnetic compass heading displayed at
the NAVIGAT X MK 1 must be determined. This requires that the vessel is swung very slowly through a full circle so that for each 10° of
magnetic compass heading (0, 10, …, 350°) the corresponding display value is obtained.
•Secondly, the resultant correction values are calculated and entered
into the magnetic compass heading calibration table of the
