8ynchro signal output

Fig. 1-6: Circuit Diagram of Magnetic Sonde

The magnetic sonde is electrically isolated from the device connected, e.g.

"PI LOTSTAR" and is supplied with a DC-free exciting voltage of e.g. 3.8Veff/400Hz at the connections R1 and R2 (see Fig. 1-6).

The output signal of the magnetic sonde is available as a 3-phase signal at the terminals S1, S2 and S3. It is formed by the voltage drop of the magnetizing current at the resistors R1, R2 and R3 (see Fig. 1-6).

Dependent on the DC field magnetization at the coil concerned, the AC excitation unilaterally reaches the saturation region of the core, as a result of which the first harmonic (e.g. 800Hz) is generated as the decisive signal component.

The DC field magnetization of the coils L 1, L2 and L3, displaced by 1200 each, takes place dependent on the angular position of the individual coil to the magnetic DC field of the magnetic compass.

Examples of the Magnetic Sonde Input and Output Signals

in Conjunction with the Autopilot "NAUTOPILOT" or "NAUTOCOURSE" (8ee oscillograms, Fig. 4-2 and Fig. 4-3)

With the exciter voltage form given in oscillogram 1 (Fig. 4-2, beam A), the oscillogram 1 (Fig. 4-2, beam B) shows the magnetizing current flow of coil 1 as a voltage drop at resistor R1 as a result of a certain DC field magnetization.

The magnetizing current is formed by the

- signal component originating from the exciting voltage (essentially fundamental component) and by the

- harmonic component generated as a result of the DC field magnetization.

The signal component of the magnetizing current is the same in all coils.

Thus, the utilizable signal component originating due to the different DC field magnetization of the individual coils can be obtained by forming the difference of the magnetizing current signal forms.

This differential signal can be measured between the terminals 81,82,83. It originates as a difference of the voltage drop at resistors R1, R2, R3.

The signal form thus obtained is shown in the oscillogram 2 (Fig. 4-3).

As to be seen from this oscillogram, the evaluation of the sonde output signals (81, 82, 83) is to be performed by demodulation of the first harmonic (here 800Hz).

Installation I Mounting

6.1

Installation and Mounting Hints

• The magnetic sonde should be mounted onto the magnetic compass on the compass bridge, if possible.

• Attachment of the magnetic sonde to the magnetic compass should preferably be made on the bottom glass disk of the magnetic compass.

• If, by way of exception, the magnetic sonde is to be fastened on the cover glass disk of the magnetic compass, the phases 81 and 83 must be interchanged.

In case a double magnetic sonde is installed, the phases 81 and 83 are interchanged for one of the magnetic sondes only.

• The connecting cable of the magnetic sonde is to be installed without buckling and with traction relief.

The magnetic compass must not be hindered in its gimbal suspension by the magnetic sonde or by the connecting cable.

• With regard to its permeability tuning, the magnetic sonde can be adapted to the magnetic compass concerned by means of spacers.

For this purpose, the 3 spacers can be shortened to the lengths required.

If, by way of exception, the spacers are not long enough, longer antimagnetic spacers must be used.

• As per B8H specification, installation must be performed by spacers whenever combined action with a Course Monitor, Type 135-079, is intended!

• On installing the magnetic sonde in systems subject to a B8H acceptance test,

use is to be made of the Junction Box, Type 134-089. By this, it is possible to remove the compass bowl together with the magnetic sonde and to store them safely e.g. in the interior of the ship. (Removal of the magnetic compass bowl is prescribed as a safety measure for protection against strong magnetic fields as occurring e.g. in the reach of magnet cranes, and as long as work is performed !)

6.2

Mounting the Magnetic Sonde

Note:

• The magnetic sonde is to be fastened exactly in the center of the cover or bottom glass disk of the magnetic compass!

In support of alignment and centering of the magnetic sonde on the cover or bottom glass disk of the magnetic compass, use is made of the centering mask

(see Fig. 7-1) .

• After the sonde has been adjusted, the enclosed adhesive label "AHEAD" is to be fastened to the sonde in the ship's ahead direction (see Fig. 6-1).

Putting into Operation

7.1

Adjusting the Magnetic Sonde

7.1.1

General

Attention!

On commissioning and adjusting the magnetic sonde, pay attention to the electrical safety regulations!

The adjusting procedure specific to the relevant system configuration is to be taken from the corresponding section of the commissioning instructions or of the appertaining device description of the device connected (e.g. autopilots NP 2010, NP 2020, NP 2030, PILOTSTAR and of the corresponding electronic connection box).

7.1.2

Adapting the Magnetic Sonde to the Magnetic Compass and Adjusting the Magnetic Sonde in Conjunction with the Autopilot

Loosen the three fastening screws (6-S.S) or (6-6.10) by means of a screw driver (for cross-slotted screws) so that the magnetic sonde can be turned with regard to its base plate. A multimeter (range 0 ... 20V DC) is to be connected as follows:

NP 2000 series on the course PCB AP 01-Z03:

L4 (sin). LS (cos) and L 1 (OV) PILOTSTAR D on the I/O PCB:

TP11 (sin), TP12 (cos) and TP1 (OV)

Now, turn the magnetic sonde slowly until the course indication on the desplay of the

autopilot connected at the time shows a magnetic course of 0°.

For the individual devices, the following voltage ranges are permissible:

- NP 2000 series: "" +4.SV DC ... +S.BV DC

- PILOTSTAR D:

Adjust the alignment of the voltage by the potentiometer 'Scale Ref. Mag' on the I/O PCB to +4.SV DC

In case of lower voltage, the distance from the magnetic sonde to the magnetic compass must be reduced (e.g. spacers to be shortened).

In case of higher voltage, the distance from the magnetic sonde to the magnetic compass must be increased (e.g. a set of longer spacers to be used).

2249E

7 - 1

MAGNETIC SONDE

Subsequently, turn the magnetic sonde slowly until the course indication on the device connected coincides with the course indication on the magnetic compass.

This procedure is to be repeated several times in order that the highest accuracy might be obtained.

Checking the correct sense of rotation of the phases:

If the magnetic sonde is slowly turned towards increasing angular degree values, the display indication must indicate the increasing angular values.

After that, the magnetic compass should be deflected several times (e.g. by means of an iron key), and the indicated values or the sense of rotation, resp., should be checked. If the sense of rotation is found to be wrong, the connections of phases

S1 and S3 are to be interchanged.

After adjustment, re-tighten the fastening screws on the clamps and secure them by varnish.

After disconnection of the multimeter, opened devices must be closed again.

After adjustment, the enclosed adhesive label "AHEAD" is to be fastened to the magnetic sonde in the ship's ahead direction (see also Section 6.2, Fig. 6-1).

Note: In combination of the relevant magnetic sonde with devices of other manufacturers the technical details of the appertaining device descriptions have to be observed!

Note in conjunction to arrangements with double magnetic sonde:

The double magnetic sonde, Type 108-010 NG003, is mechanically and electrically ready assembled and adjusted to zero.

It is - corresponding to the single magnetic sonde - to be adapted and adjusted. The right direction of rotation of the phases of each single magnetic sonde is to be attended when connected.
