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.

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 guaranteed.
There is a reduced accuracy of the compass during the settling stage.
The compass shows required accuracy after ending of the settling stage (appr. 4 hours after switching ON).

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.

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 switching off and switching on again and the compass has been switched off for a duration of min. 1 hour.
Furthermore this Qick Settling function cannot be used after first installation.

Switching on the STD 22 Compass
The compass goes into operation when the power supply is switched on from the ship’s mains.
The compass goes into the heating stage for the first 30 minutes (this period will vary depending on the temperature of the supporting liquid) and the letter “h” is displayed as the leading sign on the digital display. The follow-up system is switched off -- no course can be output.
When the temperature of the supporting liquid reaches 45 C the follow-up system switches on automatically, and the course is displayed on the compass; however deviation from actual course may still be considerable.
This settling in phase (indicated by an additional dot on the digital display) ends 4 hours after switching on. Accuracy is now < 2
After about five hours (from switching on) the compass shows an accurate heading (see
Technical Data, section 1.3.3).
The “Quick Settling” option reduces the settling in phase to one hour. With it, precision
(after one hour) is better than +/--3.

Heading correction
The information given here, in particular with regard to
Speed Error Correction, applies in general to the
STD 22 Compact compass and the STD 22 compass.
Where there is an exception, your attention is drawn to this.
The heading has to be corrected::
-- a correction depending on the alignment error
-- a correction depending on a speed error
Alignment error
The alignment error (A-error) occurs if the compass was not correctly aligned when it was installed, i.e. when the compass zero line does not agree with the ship’s--line pre-alignment. An alignment error can be corrected at max. 5 h after switching on and/or max. 5 h when the ship is moored by making readjustments (see also service manual).
To try to perform a readjustment within this 5 hours, will lead to a displayed message
“AL.no” after pressing the buttom B38 or B39 (it means: actually no readjustment possible).

4.) Press button B38 or B39 until the heading you require displays.
As you do so the course value changes (B38 changes the value downwards and
B39 changes it upwards).
If you hold down the button the speed at which it changes will increase.

Speed error
A speed error occurs while the ship is travelling. This becomes greater as the speed increases and is more pronounced on northerly and southerly courses than on easterly and westerly courses.
Speed error is a physical deviation from the steering course indicated on the gyro compass (compass course) from the true course (chart course). It depends on the speed of the ship, the course it is steering and the latitude.
The speed error is typically within the range of 0--2, and with fast ships, it can even reach 5or more.
With automatic speed error correction the compass course is continually corrected using the values shown in the speed error table (see section 2.2.2.1). The digital display on the compass and the connected repeater displays will always indicate the true
(corrected) course.
For automatic speed error correction the ship’s speed and the latitude are read into the gyro compass.
The speed error correction function on the STD22 Compact Gyro Compass
Only the automatic speed error correction function applies; in order for it to operate
GPS or Pulse Log and GPS data (speed and degree of latitude) must be supplied to the compass.
CAUTION: If the speed and latitude are not available for automatic speed error correction (Pulse Log or GPS failure), no automatic correction can take place. The gyro compass will be showing the uncorrected value.
The speed error correction function on the STD22 Gyro Compass
In this version, besides the automatic speed error correction function (with GPS and
Pulse Log data) the speed error correction function can also be carried out (with manual speed and latitude values input) manually. The speed error can be corrected manually on the Operator unit by entering the speed and latitude manually (see also Manual no.
3648 “Operator Unit 130-613”)
Add the correction value taken from the table to the uncorrected course (making sure you note the leading sign).

3 Warning signals
All warnings (see also section 3.1) are indicated on the compass by means of a flashing decimal point.
It is not necessary to acknowledge the warning on the compass.
The warning (the flashing decimal point) remains until the fault that caused the warning has been corrected.
The course indicated on the digital display unit is not affected by the warning.
EXCEPT for warning 5 “Voltage cut-off” (see section 3.1)
When a warning occurs the decimal point flashes on the compass’s digital display unit for as long as the warning is pending.
Decimal point (flashes) on the digital display unit
The procedures indicated here to temporarily remove the warning signal in some degree restrict the compass’s operational safety (if the door is open, the system’s electrical operational security, spray protection and electromagnetic compatibility are all restricted).
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.

Warnings, their causes, and what to do
There are five different warnings (numbered 1 to 6, warning 6 is not used).
These warnings are displayed on the compass’s digital display after the B38 or B39 buttons have been pressed once.
Warnings 1 to 3 are displayed when button B39 is pressed, and warnings 4--6 are displayed when button B38 is pressed.
If several warnings occur at the same time, all of the warnings are displayed.
The warnings are as follows:
1 = fan failure
2 = heater failure
3 = supporting liquid temperature is higher than 60C
Button B39
4 = supporting liquid level is too low
5 = after voltage cut-off
6 = not used

Warning 1 “Fan failure”
This warning is generated if the fan does not switch itself on as a result of the temperature of the supporting liquid (it should switch on when the supporting liquid reaches 51C).
Whether the fan is operational or not is registered from the fan’s current consumption; it therefore follows that the fan is defective if this warning is displayed.
To prevent overheating due to fan failure, it is recommended that you do the following:
-- Check whether the fan screen is covered and check to see that air can enter the enclosure unhindered at the base.
-- If necessary cool the outer sphere using an external fan.
Continue this until warning 1 stops.
It is essential that the fan be replaced at the earliest opportunity.
NOTE: A critical situation occurs, if the ambient temperature is extremely high and warning 3 is displayed “Temperature of supporting liquid more than 60C”.
Constant high temperature may effects to the life cycle of the gyro compass.
A higher temperature for a short moment has no importance.

Warning 2 “Heater failure”
This warning is output when the heater (45C) has failed.
Compass operation is not restricted if the temperature is more than 45C (see also warning “fan failure”.
A temperature drop down below 45C leads to an error message “Error” and the heading information will not longer displayed ( as well as the heading information to the connected heading receivers).
To prevent the supporting liquid from cooling further, it is recommended that to do the following:
-- Close the door on the compass, or
-- introduce warm air.
These measures should be continued until warning 2 stops.
It is essential that the heater be repaired at the earliest opportunity.
3.1.3
Edition: May 20, 2005
Warning 3 “Supporting liquid > 60C.”
This warning is output when the temperature of the supporting liquid is higher than 60C.
To prevent the temperature from rising further, it is recommended that you do the following:
-- Open the door on the compass
-- If necessary cool the outer sphere using an external fan.
-- Check the ambient temperature. If the ambient temperature is higher than
60C steps should be taken to cool it down.
These measures should be continued until warning 3 stops.
If warning 3 is displayed in combination with warning 1, the fan must be replaced at the earliest opportunity.

Warning 4 “Supporting liquid level too low”
This warning is output when the level of the supporting liquid in the outer sphere is too low. The supporting liquid is determined by an immersion probe installed in the upper part of the outer sphere.
The measure below does not compensate the planned replacement of the supporting liquid!!!
In certain circumstances (if the level of the supporting liquid falls suddenly) you must establish the cause (possibly a leak) and correct the fault.
If the level of supporting liquid is too low, the compass can be destroyed.
Immediate measure
Caution!
It is strongly recommended to perform a service within the next 6 months to check the compass.
Caution!
This immediate measure is only an exception to cancel the warning and to initiate normal operating conditions.
Caution!
Due to warning “4”, we advice to arrange a service for a routine check during the next port stay to be on safe side.
-- Switch off the compass and wait approx. 15 minutes (otherwise the gyrosphere can be damaged).
-- Open the door of the compass housing, paying attention to the earthing strip.
-- Place both hands under 2 of the 4 snap closures and release them by pressing with the thumbs.

-- Carefully turn the outer sphere through 90 and repeat the process with the other two snap closures. The outer sphere is now free and can be removed.
-- Still holding the outer sphere with both hands, lower it slightly (this releases the locking device), carefully remove it from the compass enclosure and set it down.
-- Open the ventilation outlet (Figure 15 /1), the supporting liquid screw (Figure 15 /3) and the distilled water screw ( Figure 15 /2).
-- Fill in distilled water (only distilled water from Raytheon Anschütz, part number 148--398, one 230cm 3 bottle) into the inlet for supporting liquid until the measuring cone shows “Level O.K.”, see Figure 16 .
-- Fill in the remaining content of the bottle into the inlet for distilled water until the
Dip--Stick shows a level according to Figure 17 .
-- Close all in-- and outlets, if applicable use new sealing rings.
-- Place the outer sphere in the compass enclosure.
-Pay attention to the two locking pins on the closure.
-- Hold the outer sphere with both hands and guide it under the snap closures on the pendulum joint.
-- Using the thumbs, press down and engage the two snap closures.
-- Carefully turn the outer sphere through 90 and repeat the process with the other two snap closures. The outer sphere is now fastened to the pendulum joint.
-- Close the door of the enclosure and fasten it with screws, paying attention to the earthing strip.
-- When the power supply is switched on, the compass is ready for use again.

Warning 5 “Voltage cut-off”
This warning is output if the supply voltage is cut off for a short time. The cut-off period is determined by the fall in supporting liquid temperature. If the temperature falls below
45C the compass recognises that the voltage supply has been switched off in the conventional way.
In the case of a voltage cut-off (supporting liquid temperature does not fall to below
45C) and the voltage supply has been restored, the settling stage in indicated again
(see also section 2.1.1 “Compass indications during the settling stage”).
Note: Heading indication can be incorrect. Wait for a complete follow up,
Check voltage supply to the gyro compass!

Figure 18 : Digital display for “Voltage cut-off”
If voltage cut-offs occur often, the following checks should be made:
-- check the on--board power supply or
-- check the the on-board power supply distribution unit compass cable connections or
-- check the the on--board power supply AC/DC converter compass cable connections

Alarm signalling (in the event of an error)
Alarms are indicated on the compass as follows:
The course is not displayed, as well as at the connected heading receivers !
An alarm signal is indicated on the digital display by means of a flashing Erro (for Error)
(flashing “OFF”), flashing “OFF” occurs only when the voltage is too low.
After the blinking “Erro” the compass internal PC--board which fails and an error code is displayed (detailled information --> see Service manual).

Switching off the Gyro Compass
The gyro compass ceases to operate when its power supply (ship’s mains, AC/DC converter) is switched off.
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 gyro system could be damaged!
