1. Description

This section of the Maintenance Manual covers all three variants of the

Course Computer:




1.1 General

The Type 100/300 Course Computer is SeaTalk compatible and consists of a case containing a PCB which carries a microcontroller, drive unit, power amplifier, protection relays and a connector block for all inputs and outputs.

Type 100 is used with Type 1 and Type CR 12V drives. Type 300 is used with Type 2 and Type 3 12V or 24V drives.

1.2 Variants

Functions of all three variants are identical. The difference between Type

300 24V and Type 300 12V is the input voltage and motor output voltage.

Between 12V variations, Type 100 and Type 300, the difference is the power handling capabilities of the motor output.

All other inputs and outputs (SeaTalk, compass etc.) produce or need the same signal levels whatever the variant.

Mechanically, all three variants are identical in that the computer consists of a case with top and bottom parts containing a PCB.

2. Operation

There are no operations needed to set up the computer for testing.



3. Disassembly

Refer to Figure 1, Exploded View.

1. Remove the terminal cover (1)

2. Unscrew and remove the four M3 screws (12) on the lower case (11).

Remove the lower case

3. To remove the PCB (8), unscrew and remove the five M2 screws (9).

Unscrew by two or three turns the location comb screws (5). (Note that computers from serial number 0360001 use machine screws and require a 2.5mm hexagon key). Access to these screws is gained through two holes in the PCB, one of which is shown in Figure 2, behind and to the left (as viewed) of the line of FETs (13). Do not remove the screws at this stage. Lift the PCB out of the upper case (2)

4. Remove the location comb (4) by unscrewing and removing the two screws (5)

5. If the insulation strip (3) is damaged, out of position or a new location comb is to be fitted (see Assembly Instruction 3), carefully peel off the old strip and clean any remaining adhesive and heat transfer compound off the case

6. The insulating strip (10) fits over the legs of the connectors and can be removed if necessary.

4. Assembly

Refer to Figure 1, Exploded View and Figure 2, Location Comb Assembly

Detail.

1. Apply heat sink compound (14) to the area of the case where the insulation strip (3) fits. Apply double sided sticky tape to the case and attach the insulation strip as shown in Figure 2 detail 1. Bend the strip over the edge and apply a second layer of heat transfer compound

(Figure 2 detail 2)

2. Fit the location comb (4) into the upper case (2) with the two M2 screws

(5). Do not tighten the screws at this stage. (Note: Check that the location comb has the new shape as shown in Figure 2. If not, use

Autohelm Course Computer Modification Kit Q098 to replace the old shape comb with a new shape comb)

3. To replace the PCB (8) in the upper case (2), hold the lower case so that the location comb falls away from the insulation strip (3). Ensure that the lip of the location comb does not come out of the flange in the case.

4. Position the PCB next to the upper case (2) and bring the two together so that the FETs (13) are between the location comb (4) and the insulation strip (3) (Figure 2 detail 3) . Ensure that the lip of the location comb

9. Circuit Description

Note that the electrical difference between the Type 100 and Type 300

(12V) computers is in the power stage of the motor drive circuits. The Type

100 uses IRF Z34 FETs or equivalents, and the Type 300 (12V) uses the more powerful SMP60N06 - 18 or equivalents.

The Type 300 (24V) also uses SMP60N06 - 18 FETs or equivalents.

9.1 Power Supplies

Type 100 and Type 300 (12V)

Refer to Figure 4, Block Diagram (Power Circuits) and Figure 10, Type 100 and Type 300 (12V) Circuit Diagram.

A nominal 12V is applied to V+ and V- pins of terminal block 1 (TB1).

Varistor V1 gives protection against transients and over - voltage.

After passing through link LK1 the supply is called V12 and is routed to:

1. IC1, a regulator which generates 5V for the logic circuits and reset signals for the microcontroller

2. Via fuse FS1 to SeaTalk terminal blocks TB4 and TB12

3. Diode D9, to become VBUS at D9 cathode.

VBUS is applied to:

1. R131/ZD3 to produce a 6.8V supply to the analogue - to - digital circuit

(IC3a, IC3b)

2. NMEA OUT buffer (TR12, 13, 14 and 15) to give the correct NMEA signal level at TB6

3. TR3 to provide the correct SeaTalk output signal level at TBs 4 and 12

4. Rate Gyro and Roll Gyro via TBs 9 and 10 respectively.

If the supply polarity is correct, incoming 12V is passed through protection diode D19, and is applied as VPOWER to the clutch and motor drive circuits.

VPOWER is applied to FETs TR20 and TR21 through link LK3. Signal P3.4

is applied to TR18 which, with TR19, drives FETs TR20 and TR21 to produce supply VDBL via C17. VDBL is up to 12V higher (maximum voltage is limited by Zener diode ZD2) than VPOWER. This supply is applied to transistors TR22 and TR28 to ensure that FETs TR23 and TR27 are turned hard on when required by microcontroller signals P1.6 and P1.7.

FETs TR23, TR26, TR27 and TR29 are arranged in a conventional bridge



network to supply motor drive power via TB8.

Clutch energisation is provided by FET TR38 via TB7. Drive transistor TR39 is supplied with VDBL to ensure that TR38 is turned on hard as required by microcontroller signal HP - ENABLE. VPOWER is fed to TR38 through link

LK3 in these versions of the PCB.

Resistor R82 and Zener diode ZD1 provide supply VREG to the motor drive transistors TR25 and TR30 to ensure that the gate voltage of FETs TR26 and TR29 never exceeds 12V.

The +5V supply is used by resistor chain R19, R20, R21 and R119 to produce VREF, which is supplied to AD convertor IC3 as an input reference and to the fluxgate compass via TB11 as coil bias.

Relay Energisation

Figure 10, Type 100 and Type 300 (12V) Circuit diagrams and Figure 4,

Power Circuit Block Diagram, contain relay energisation circuits used on:

Q068: PCB Serial Numbers below 0440028

Q067: PCB Serial Numbers below 0540001

The clutch is energised by signal HP - ENABLE from the microcontroller, and TR2 provides RLY - 0V which energises RL1. The contacts of RL1 short out D19 allowing current to flow to the bridge circuit with minimal voltage loss. When the clutch is de - energised, RL1 is also de - energised and the relay contacts open.

Relays RLY2 and RLY3 provide isolation for the PCB circuitry in the event that power is connected to the motor terminals by mistake.

RLY - 0V also energises relays RLY 2 and RLY 3, closing the relay contacts and allowing motor drive power onto the terminal block.

The contacts of RLY 2 and RLY 3 are opened when the clutch is de - energised.

Figure 5 shows the modifications to the Circuit and Block Diagrams on

PCBs with serial numbers greater than 0440029 (Q068) and 0540001

(ZQ067) where energisation of the relays is immediate on application of the correct polarity supply voltage.

VBUS, V12, VADC, VREG and VRESET are the same as the 12V versions.

The differences are:

1. V12 is generated by switching regulator IC13

2. VPOWER is 24V (nominal)

3. VDBL is 36V (nominal)

4. Clutch drive transistor TR38 is supplied with 12V through link LK2

5. Links LK1 and LK3 are open, and link LK2 supplies 12V to FET TR38 to control the clutch.

Diode protection of the clutch and motor drive circuits against reverse polarity supplies is as for the 12V versions.

Relay Energisation

Relay energisation is the same as Type 100 and Type 300 (12V). Figure

11, Type 300 Circuit Diagram, and Figure 6, Power Circuit Block Diagram show the method used for PCBs with serial numbers below 0440127.

Figure 5 shows the modifications to Circuit and Block diagrams for PCBs with serial numbers greater than 0440127.



9.2 Signal Processing

External Signals

Refer to Figure 7, Block Diagram (Logic Circuits) and either Figure 10 or

Figure 11, Type 100 and 300 (12V) and Type 300 (24V) respectively.

Signal and processing circuits are identical for all three versions.

Fluxgate Compass

Compass Drives (1 and 2) are provided at TB11 by TR32 and TR33.

VRESET on TB11 provides a bias voltage to the compass coils.

Compass outputs F/GA and F/GB are routed via TB11 to analogue multiplexer IC2.

Rate Gyro and Roll Gyro

Both gyros are supplied with VBUS (nominal 12V) through TB9 (Rate) and

TB10 (Roll). Gyro outputs are fed from the respective TBs to analogue multiplexer IC12.

Rudder Reference

The Rudder Reference transducer is supplied with 5V through TB2. The reference output is routed via TB2 to analogue multiplexer IC12.

Joystick

The Joystick is supplied with 5V through TB3. The joystick output is routed via TB3 to analogue multiplexer IC12.

SeaTalk

SeaTalk data passes through TB4 and/or TB12. Selection of SeaTalk input/output is made by microcontroller signal P1.4 .

Incoming data is applied to TR10/11 and hence to microcontroller inputs.

Outgoing data is generated at microcontroller output P3.1 and is applied to TR4, TR5, TR6 and TR7 to provide the 12V signal level of the SeaTalk system.

NMEA

Selection of NMEA output is made by microcontroller signal P1.5.

Incoming data on TB5 is applied to optocoupler IC4 and hence to microcontroller inputs.



Outgoing data is generated at microcontroller output P3.1 and is applied to TR12, TR13, TR14 and TR15 to provide the NMEA 12V signal level at

TB6.

Internal Signals

Input signals from external instruments (compass etc.) are applied to analogue multiplexers IC2 and IC12. Selection of the signal for application to the A/D convertor IC3 is made by signals SEL A, SEL B, SEL C in combination with INHIBIT A and INHIBIT B. Selection signals are generated by

Channel Select IC10 using data from the microcontroller.

The microcontroller accesses RAM, EPROM and EEPROM to store/retrieve program and factory - set calibration parameters.
