Safety Information
Caution!
Maintenance and repair work should be carried out only by trained
and qualified staff who are well versed in national safety
regulations.
After the gyro compass has been switched off it is necessary to
wait at least 15 minutes before accessing the interior of the gyro
compass.
Otherwise the sphere could be damaged!
If no Raytheon repeater compass or other alarm indication device
is connected, the warnings and error messages are only displayed
visually on the compass.
In such case, the gyro has to be installed in such a way, that the
digital display can be monitored at all times -- see installation
instruction.
If warnings occur, the operation of the gyro compass is not
restricted. If the cause of the problem is rectified quickly, it is
possible to prevent the equipment from breaking down.
Please inform the authorised service staff.
When an error message appears, the heading is no longer
displayed at the compass; the heading is not followed up at a
connected heading receiver.
The compass must be repaired by well trained stuff.
Please note that all ships of 500 gross tonnage and upwards according
to SOLAS regulations must be equipped with a gyro compass.
The gyro compass must be operational. For this reason it is not allowed
to have a switched--off gyro compass during voyages.
A switched--off gyro compass during voyages could cause damage
to the gyrosphere.

Edition: Feb. 17, 2006
Caused by technical progress the PC--Boards of the
Gyro Compass are changed.
Due to that some pictures and/or procedures have been
changed.
Respective changes are marked with “E10”.
The AC supply voltage (ships mains) may drop out.
This leads to a restart of the gyrocompass and a new settling
stage.
The heading information during this settling stage has a
reduced accuracy (see section 2.1.2).
Therefore a continously supply with 24VDC should be guar-
anteed.

1 General
This compass is designed for use as a navigation aid on board ships.
As a sensor, and unaffected by the magnetic earth field, it determines the north bearing,
and thus enables a course to be steered in relation to true north.
This compass provides course information and status signals to those responsible for
course setting.
In principle we can distinguish between two different applications for the compass:
The STD22 Compact Compass as a stand--alone system
and
The STD 22 Compass used in conjunction with other system components such as a
magnetic compass, GPS or other STD 22 gyro compasses. An Operator Unit and a
Distribution Unit are required to connect and to operate these system components.
The overview on the next page illustrates the functional differences between these two
versions.

1.1 STD 22 Compact Gyro Compass
The position and speed (GPS and Pulse Log) are supplied to the compass as input data.
Both types of data are required for the automatic Speed Error Correction function.
To activate this function the QS Operator Unit can be connected to the gyro compass as
an option.

Speed Error Correction (SEC)
This function automatically corrects the latitude error of the gyrosphere error in the gyro
compass. The gyro compass receives the data required to make the correction, such as
the speed and latitude, from GPS receivers, NMEA 0183 resp. from the Pulse Log.

Optional features:
-- QS Operator Unit, 130 -- 606
-- AC/DC converter, 121--062
-- Additional Output Box,146--103
The Speed Error Correction function is available only when a GPS or Pulse Log is
connected.
The output interfaces on the STD 22 Compact are as follows:
-- Course (corrected -- SEC) as NMEA or course bus
-- Status signals (alarms, error messages, warnings)
Optional via the Aditional Output Box box:
-- NMEA 0183 superfast (50Hz)
-- Step (6steps/degree)
-- SSC
The input interfaces on the STD 22 Compact are as follows:

1.1.2 STD 22 Compact Gyro Compass optional features
1.1.2.1 Quick Settling operator unit
The “Quick Settling” function reduces the time the compass requires to settle to
approximately one hour.
The most recent heading is stored when the gyro compass is switched off. When it is
switched on the compass uses that value to make a default setting so that the settling
time is reduced.
The Quick Settling function can only be used if the ship‘s
heading has not been changed between swiching off and
swiching on again.
The Quick Settling function cannot be used:
-- During the first setting into operation (after installation).
-- If ship’‘s heading has been changed after switching off
and switching on again.

1.2 STD 22 Gyro Compass
In this application the gyro compass is operated on a bus system (CAN bus). With this
application there are more extended options for connecting external equipment, and
considerably more course receivers can be operated.
This application needs to be equipped with a minimum of a type 130-613 Operator Unit
and a type 138-118 Distribution Unit.
A magnetic sonde can be connected directly to the Distribution Unit.
