1 Installation and First Setting into Operation

1.1 Safety Notes

ATTENTION In opened devices or desks, voltages representing a risk of

electric shock are applied.

-- SAFETY INSTRUCTION --

As a matter of principle, the system is to be made dead

when installation work is performed on the equipment aswell as during disassembly/assembly of components or dur-

ing alteration of the circuitry.

ATTENTION The adjustment work described in this section must only be

carried out by trained service personnel observing all safety

measures!

For all work that results in a movement of the rudder, a pre-

vious check must be made to guarantee that neither person-

nel nor material will be in danger from the rudder or the

steering gear!

1.3 Planning the installation and instruction for installation

1.3.1 Operator unit (dimensional drawing 102 D 886.HP007)

Conditions at installation site:

The device must be located in a position where it can be easily seen, and

from which it is comfortable to operate.

The data required for flush mounting the equipment are provided in dimensional drawing

102 D 886.HP007 and are binding (cut--out section and drilling scheme).

NOTE

Before starting work check that there is sufficient room

beneath the cut--out section you have selected to carry

out the necessary sawing work!

1.3.2 Connection unit (dimensional drawing 102 D 885.HP005)

Condition at place of installation:

The connection unit should be sited within a radius of appr. 3m from the

operator unit.

dimensional drawing above the connection unit is available.

1.3.3 Rudder angle transmitter unit (dimensional drawing 101 C 528.HP00

Condition at place of installation:

1. if linkage transmission has been selected, it is essential to ensure that it

cannot be blocked by any loose objects!

All cables within this radius must be fastened down.

2. if toothed--belt transmission has been selected, it must be correctly

pre--tensioned beforehand.

All nearby cables must be fastened down.

1.4 Basic version: Installation and setting into operation

1.4.1 Installing the connection unit

NOTE: Please see drawing102 D 885.HP005for detailed dimenion data.

The connection Unit should preferably be bulkhead--mounted. The distances between

mounting screws can be taken either from the dimensional drawing or from the connec-

tion unit itself.

The connection unit is mounted by fitting 4 screws through the recesses provided.

5 mm wood screws should be used to fasten the unit onto wood, the length of screwshould be chosen to suit the thickness of the base.

M5 screws should be used to fasten the unit onto metal, the length of screw will depend

on the thread length in the base.

NOTE: When mounting the connection unit ensure there is sufficient claer space

around the connection unit. It must be possible to replace the covers and

screw them on without hindrance .

Ensure there is sufficient space for the on--board wiring!

1.4.2 Installing the operator unit (desk mounted)

NOTE: Please see dimensional drawing 102 E 886.HP005 for detailled

dimensional data.

Prior to fitting, a cut--out section should be cut away from the desk as indicated in the

dimensional drawing.

1.4.2.1 Mounting the rudder angle transmission system

NOTE: Please see dimensional drawing101 C 528.HP005for detailed

dimension data.

Depending on the amount of space available on board and the working range of the rud-

der, one of two types of transmission can be selected.

(1) Linkage transmission

With this type of transmission the appropriately adjusted flat steel piece supplied

with the unit must be mounted to the rudder spindle (if not already present) in ac-

cordance with the dimensional drawing.

The transmission ratio is 1 : 1 and can be configured for operating angles of 0 to

45. The drive shaft consists of a driving lever, two ball and socket joints and a

connection threaded round bar.

Once the driving rod has been carefully adjusted, the threaded round bar between

the two ball and socket joints should be shortened to the required length.

Systems withup to a maximum of two feedback units willtherefore require two driving rods.

After fitting, transmission should not be endangered fromloose objects in the area of the lever.

All acbles situated in the action range of the lever must befastened down.

(2) Chain drive

(Refer to dimensional drawing 101--528.HP005)

For rudder angles of max. +90, the drive of the feedback unit should be via chain

wheels and chain.

The transmission ratio from chain drive is 2 : 1.

The tapholes (e.g. M6, depth 20mm) required for fastening the chain wheel to the

rudder stock are to be centered on the plane surface of the rudder stock. Then the

chain wheel is to be screwed on and to be pinned by means of cylindrical pins. To

ensure automatic chain tension, a chain tightener is to be mounted and to be pla-

ced in accordance with space conditions (chain tightener included in the scope of

delivery).

NOTE: For systems of 2 feedback units, two chain wheels -- arranged in

Below mentioned sequence has to be followed

1. Adjusting of the rudder--feedback Circuit (Offset and Scale) by potentiometers.

If the rudder does not follow the ruddercommand, change the polarity of the feedback

supply voltage from L1.32 to L1.35.

If the rudder moves to the opposite side, change the starboard/port cable connections

(see connection diagram, section 1.6.5.1)

2. Adjusting of the rudder slack and the rudder--overshoot D--Return (ifnecesary).

3. After adjustment the cable link between L1.10 and L1.12 has to be removed or

FU Set up must be deselected.

1.6.2.3 Adjustment of Rud Slack (Limits/Values).

Single Pump operation

Activate key: Limits/Value .

Rud Slack (Default--Setting=1) decrease until the rudder starts to hunt.

Increase this set value until the rudder is to stabilised.

Set nominal value to 10 (--10) and let the rudder run to 0.

Continue to optimize Rud Slack if necessary. After optimized adjustment of

Rud Slack below mentioned adjustment have to be repeated:

-- Offset value with potentiometer R149

-- RuderScale with potentiometer R154If the rudder runs over the nominal value, there is the possibility to switch off the rudder

by D--Return 1 (see section 1.6.2.4) before it reaches the nominal value.

1.6.2.4 D--Return Adjustment

Activate key Limits/Values.

With this parameter (D--Return) it is possible to create a rudder--lead.

This rudder--lead switches off the rudder--control before the nominal value is achieved.The D--Return--value has to be set in such a manner, that an overshoot of the rudder

over the nominal value is prevented.

Possible settings are 0 to 16.

Setting 0 means that the D--Return is switched off, 10 is the maximum setting.

Has to be checked!!!

In case of troubles on the feedback--signal (50Hz) the D--Return value has to be redu-

ced or set to 0 otherwise there will be a multilple valve--activation.

The safety of the valve--control has highest priority.

The respective switching--pulses are monitored as LED--control--signals at the I/O--PCB.

1.6.2.5 Adjustment of double--pump operation

(Switch on pump 2)

Because the rudder--moving--speed is duplicated with 2 pumps, the rudder slack should

be adapted to fast rudder operation.

Rud Slack 2(Default = 1)

This adjustment procedure has to be performed according to section 1.6.2.3.

Scale and offset setting should not be changed.

D--Return2 (Default = 0)

Because of the higher rudder--moving--speed there may be a requirement to set another

D--Return.This procedure has to be performed according to section 1.6.2.4.

1.6.2.6 Offset Adjustment of the analog Nominal--rudder lines

Activate key Limits/Value.

Select parameterOffs. Ana 1.

Measure the volatge at the analog output L1.1 L1.2 while the rudder

position is 0.

The offset value can be compensated stepwise (depending on polarity + or --) within a

set range of 0...+/-- 200.

1.6.2.7 Adjustment of the Rudder 1 Feedback Input

If the feedback input receives its signal from a external Follow--Up amplifier or from a

Rudder--position amplifier, than an offset and scale adjustment has to be performed

also.

The 10V has to be optimized to max. rudder position.

To do this, it is possible to display the actual rudder value at the operating unit

(use the display key to look for the actual rudder).

Set rudder to 0position and adjust the offset to 0with potentiometer R 149.

Set rudder to Stb 30and adjust 30with potentiometer R 154.Check this adjustment at rudder position of Port 30.

(1) Rudder does not reach its end position

If the rudder--end--position is not reached by the setting of the nominal value, the

amplification factor has to be increased by potentiometer R154 (see

LEERER MERKER) until the actual value at the display of the operating unit is

identical to the mechanically position of the rudder.

(2) Rudder--end--position is reached untimelyThe amplification factor has to be decremented with potentiometer R154 until the

nominal value is identical to the mechanicaly position of the rudder.

(3) Offset correction

After the adjustment of the nominal values we recommend a correction of the elec-

trically offset. See section 1.6.1 .

Rudder 2 Feedback input:

This input is fixed to +/-- 10V according max. rudder and cannot be adjusted.

After the adjustmens of the autopilot control,the jumper between L1.10 and L1.12 has tobe removed.FU set up has to be switched off via operatorunit.

The autopilot NP 2035 is designed to reach high performance track control acc. to DNV W1

classification.For that reason, it is equipped with different controllers forheading control and

track control function.This leads into additional parameters to be adjusted.Thefollowinglist

of track control parameters (started with item No.45) includes some parameters which have

to be adjusted in any case, few parameters which have to be adjusted sometimes , parame-ters which have to be adjusted only acc. to the agreement of the development department

andsome parameters which areonly for developmentdepartment use(activation of special

functions, to avoid new software versions for special behaving ships). The last two groups

are labeled in the list.

The parameter list for track control is frozen and can not be influenced by the user. The para-

meter settings done by the user influences only normal heading control function.

(5) Adjustment of Controller

To reach high performance track control, the autopilot NP 2035 controllers for headingcontrol and track control need different sets of parameters, which have to be adjusted

separately. The track controller parameters are to be determined and adjusted complete

separately. For that reason a special adjustment function is implemented. This function

allows to adjust some of the track control parameters without entering track control

mode.

The procedure is the same as to adjust a standard heading controller. The parameters

are named equal. The following procedure describes the steps for the adjustment:

1. Activate the Heading Controller Part of the track controller.

Enter the ATCPAR menu and set ACTCrseCtl to ON (menu item No. 46).

Having done this, the controller for normal heading control is switched off.

After finishing the adjustment work at track controller, the normalheading controller has to be switched on again(setting ACTCrseCtl to OFF)!

2. Now adjust the ShipL, CR_act, R_act and Yaw_act parameters using heading controlmode.

3. Switch off ACTCrseCtl!!

4. Adjust PivotPt using track control mode.

TMC REF Fail alarm may be indicated on the display.

3.) Voltage Uref(AC) on R1 to R2 has to be appr. 1.8 Veff(400Hz).

4.) Connect a voltmeter (DC range) to TP 13 (TP14) and TP 1 (GND) ofNP2035 I/O--PCB.

5.) Turn the Sonde in its support until you read on the meter a voltage maximum

between +3.8V to 4.3V.

6.) If the voltage is +4.3V adjust with potentiometer R41 REF.MAG.

7.) In case the voltage is not adjustable with potentiometer R41, the Sonde has to be

altered closer to or further from the Magnetic compass.

8.) After distance alteration, repeat the voltage adjustment with Potentiometer R41

until TMC REF Fail disappears.9.) Thereafter adjust the Sonde in its support until the Autopilot display shows the

same heading values as the Magnetic Compass and tighten the Sonde.

The potentiometer R59 SCALE SIN is for factory adjustment only!

In case it was disadjusted by fault, readjust as follows:

Turn the Magnetic Compass Card with an iron tool to 45card reading. With this voltage

an TP 13 to TP 1 and on TP 14 to TP 1 of the NP2035 I/O--PCB has to be the same ma-

gnitude. If not readjusted with potentiometer R 59.

2.1 Safety Instructions

Warning!

Thissystemdoesnothaveasafetylockingdevice.Inthe

opened unit there is dangerous voltage accessibility.

Before carrying out maintenance or repairs, make sure

the voltage is turned off and secure against inadvertent

switching--on.

ATTENTION

Observe

handling regulations!

Electrostatic

sensitive components

CAUTION

Handling of electrostatically sensitive semiconductor components

Static voltages can damage certain semiconductor assemblies used within the system.

The following safety precautions should therefore be observed when these components

or units are being taken out of the system as they are then in danger of being damaged

by static charges due to open inputs of the semiconductor components.

1) Persons removing units from this system must be grounded by a wrist band. Thewrist band must lead via a ground cable to a central ground point in the system.

2) When using a soldering iron during repairs, the tip of the device must be used with a

low voltage supply and grounded. The iron must be separated from the mains by a

doubly insulated transformer.

3) Clothes must not produce any static charging.

4) Printed wiring boards that are fitted with these components must be stored andtransported in anti--static containers.

3 Constructional features of the NP2035 Autopilot system

3.1 Basic SystemThe autopilot system is comprised of the following components (see Fig. 3--2:)

Operator unit

The control unit is suitable for installation in bridge desks, steering stands or

for installation in a swivel housing:

Control Unit

The main components of the control unit are:

-- a rack serving as central assembly housing for various electronic PCBs

-- the backplane for EMV and internal connections

-- the terminal connection block for ships wiring

3.1.1 Operator Unit

The Operator Unit is the interface between the connection unit, the steering control andthe connected periphery devices.

There are various PCBs within the Control Unit.

A rack is used for housing the assemblies.

The operator unit is designed for installation in a control desk.

General operation is via inscribed membrane keys which are subdivided into two

groups:

-- Command keys for selection of the operating mode.

-- Function keys for individual adaptation

Several of the silicon keys are equipped with an LED display:

-- when the LED is lit this means,

the key and the corresponding function has been chosen.

-- when the LED flashes this means,

a system message (alarm, warning, value acceptance) is waiting and has to be
