SAFETY
Safety instructions
Please respect all instructions of this manual.
All texts marked with this symbol should have your
particular attention.
They are indications of particular importance for the
operation of the system and for your safety.
The use of the compass system does not relieve you of the responsibility for your ship, and requires good seamanship.
Always rely on your nautical experience for the interpretation of the indicated values.
Safety Instructions concerning the installation:
The compass system should be installed by your shipyard or by a specialist.
Use adequate working clothes if you install it yourself. Avoid loose clothing. Use a hair net if you have long hair. Clothing and hair may be
caught by moving parts.
Remove all metallic or electrically conducting jewelry, such as chains,
bracelets, rings, etc. when working on the on-board electrical system.
Disconnect the minus polarity of the battery before starting your work to
prevent the risk of a short-circuit. Short-circuits can cause harness fires,
battery explosions and damages of other electronic memory systems.
Please note that all volatile electronic memories will lose their contents,
and will have to be re-programmed if you disconnect the battery.
VDO instruments are not equipped with volatile memories.
Risk of explosion! Run the engine blower for a certain time before starting work in a gasoline engine compartment.
Check for sufficient clearance behind the mounting hole when selecting
the location for the indicating instrument. Pre-drill the hole and finish with
hole or keyhole saw (respect the safety instructions of the tool manufacturer).
25
SAFETY
Check that no stringers are damaged when selecting the location for the
sensor installation. Check for furniture, floor boards, boxes, cables, etc.

INDICATING FUNCTIONS
The indicating functions of the VDO Compass
The indicating instrument displays the following course information
when the power is switched on:
Course indication

The display indicates the steered course (267° in the example).
The pointer is in “OFF” position and has no function.

or
Desired course with deviation
2.
The display continuously indicates the desired course.
This course indication (270° in the example) is preceded by a „S“.
At the same time the pointer indicates the deviation from the desired course (3° port in this case).
The indication corresponds to the active mode (1 or 2) when the power
S 270
supply was shut off.
The pushbutton toggles between both indicating modes.
The indicating instrument must be in course indication mode to indicate
a specific course as the desired course.
Set the ship to the desired course and push the button. The current
course is stored as the desired course, and the pointer moves to center
position (deviation 0°).
Each deviation from the desired course is indicated by the analog pointer (3° port in this case).
29
COMPENSATION
Automatic compensation of the VDO Compass
All on-board iron masses of a ship are more or less magnetic and influence the compass. This effect must be compensated in a fluid compass
as well as in a fluxgate compass.
On conventional fluid compasses this requires the services of a qualified
specialist. On the VDO Compass with its automatic deviation compensation you can easily and reliably perform this adjustment yourself. As supplied the VDO Compass behaves like a normal, non-compensated fluid
compass.
Perform the automatic compensation during a circular course with calm
sea, at a sufficient distance to port installations and magnetic disturbances (such as steel bridges, sheet piling, other ships). The diameter of
the circle should be five or six times the ship length, the speed adapted
to complete one circle in about 3 minutes.
No valid course is indicated by the instrument during the compensation.
Perform the compensation as follows:
Start the circular course and switch the power supply on while keeping
the button pushed.
The display indicates „
OFFSET

Continue the circular route until the compensation is automatically ended. After successful compensation the desired course is indicated
(267° or 270° in the example).
267 s 270
For your own safety you should verify the indication by several true observations on various courses (north, east, south, west). Differences
between compass indication and true observation must be corrected by
adjustment of the compass sensor position (see page 33).

The display shows „

“ in the case of a failure of the automatic com-
or
FAIL
In this case exit the failed compensation by switching the power supply
off. The pointer returns to its normal operating mode when the power is
switched on again. Repeat the automatic compensation.
The following factors may cause a failure of the automatic compensation:
- Excessive speed during the automatic compensation
- Inadequate installation of the sensor (see page 36)
- Mobile phones or radiophones were used during the compensa-
tion
- Influence of magnetic disturbances (bridges, pile walls, etc.)
or magnetic objects near the sensor.
31
POSITION-DEPENDENT VARIATION
The automatic compensation should be repeated after compass installation, after slipping, prior to long routes, after welding operations, after the installation of electrical consumers,
but at least once a year.
Please also note the „semihard magnetism“ effect on steel
ships, which appears when the ship has been exposed to the
terrestrial magnetic field without position change for a long time
(for instance during winter). After some days in the water this
effect has disappeared. This means that after watering a ship
the compass compensation should be repeated several days
later.
Setting of the position-dependent variation
This operation is necessary to set the valid local variation. The angular
variation is found in the nautical map. Setting the variation eases working with the map, and after compensation (see page 30) the compass
will indicate the true course.
Enter the variation as follows:
Switch the power on while keeping the button pushed. The pointer is in
„OFF“ position, and the display indicates „
OFFSET
“.

Release the button when „
cated after several seconds. In the system as supplied the indication will
be 0.

OS 000
(Note: You have about 5 seconds to start the „OFFSET“ function, after
this time the function is automatically exited). For each button activation
the value is incremented by 1°. Hold the button down; the value will increment at increasing speed up to 100°, then it will decrement from -100°.
Positive setting = variation in eastern direction.
Negative setting = variation in western direction.
Release the button after setting the correct value (3° in the example).
After some seconds the display automatically changes to „CAL“.
After another 5 seconds a normal course indication is shown (in the ex-

ample steered course 267°), taking the variation into account.
OS 003
CAL

The set variation value remains stored in the VDO Compass, even when
it is switched off.
Adjustment of the Compass Sensor
A correct adjustment of the compass sensor is necessary if, after compensation and variation setting, differences are found between the true
compass course and the true bearing.
On each course (N, E, S, W) note the measured differences
Difference = true bearing - compass indication.
(e.g. true bearing : 001°, VDO Compass: 002°, difference north: -001°).
Calculate the average of the differences.
The average is the angular value by which the compass sensor must be
turned for correct adjustment.
A positive sign (+) means that the sensor should be turned clockwise, a
negative sign (-) means counterclockwise.

Installation of the compass sensor
Using the fluxgate principle the terrestrial magnetic field direction and
strength are measured by two crossed coils. In the case of hulls made of
wood, reinforced polyester, Kevlar or aluminium the sensor can be installed in the hull; in the case of steel or steel-reinforced concrete the
probe must be installed at least 1 m above deck, but not higher then 5 m.
36
When installing the sensor check for sufficient distance to fixed metal parts, electrical cables and other objects creating
magnetic fields.
Check for sufficient distance to all portable disturbance sources, such as cans, pans, radios, mobile phones in operation,
etc.
INSTALLATION
Temporarily install the sensor and make the first compensation run. A
different location must be selected If several trials are not successful.
After finding an adequate location fix the sensor with three brass or
stainless steel screws to allow a rotation of the sensor for adjustment at
a later time (see page 33).
Mark the location of the sensor with the supplied warning label.
