DESCRIPTION The Repeater Compass System receives through an RS 422 serial interface angular information according to which the rotor of a step motor is driven to a related position. The compass card system is coupled to the step motor through a gear train. The Repeater Compass System comprises basically two standard compass card assemblies, one with a 360° card and a second with a 360° and a 10° card which, are supplied in a housing as demanded by the associated application.
1.
Outline The repeater compasses display the vessel's heading as supplied by a gyrocompass, a transmitting magnetic compass system or an electronic compass.
1.1.1.
System Overview A suitable repeater compass is available for all applications and all locations. • Bearing repeater compass with a 360° card, watertight, for installation in a bearing stand or a bulwark console. • Bulkhead repeater compass with a 360° card, watertight, for attachment to all level vertical, horizontal and inclined surfaces. • Console repeater compass with a 360° card for installation in a bridge console. • Steering repeater compass with a 360° and 10° cards for installation in a bridge console. A bearing stand and a bulwark console complete the system.
1.1.2
Display All repeater compasses display the vessel's heading on a 360° compass card. An exception is the steering repeater, which has a 360° and a 10° card. Graduations and figures appear white on a matt black background during daylight and red illuminated during the hours of darkness. The luminous yellow lubber line facilitates exact reading.
1.1.3
Power Supply The repeater compasses are provided with power and heading information from the Electronic Power and Control Unit (EPCU) of the NAVIGAT X or NAVIGAT XII gyrocompass systems. In addition to, or as an alternative for a gyrocompass system, the repeater compasses may also be used with a transmitting magnetic compass system. The heading signal in a C.PLATH, NMEA or Lehmkuhl format is received by the repeater through an RS 422 interface. The LED card illumination is provided with 24 VDC.

Technical Description
1.2.1
Standard Compass Card Assembly The main element common to all repeater compasses is the standard compass card assembly. In contains a 360° compass card (only the steering repeater has an additional 10° card), a step motor, a gear train, LED illumination, three terminal blocks, a microcontroller, an EPROM, an EEPROM, two dip switch blocks, a 7-segment LED display for trouble shooting and several red and green indicator LEDs. The robust printed circuit board mounts not only the electronic components but also the gear train and the step motor. The three hard-wearing plastic gearwheels which make up the gear train run on bronze shafts and bushes. Red LEDs provide full compass card illumination. The compass cards are graduated as follows: Bearing repeater compass 360° card: one graduation mark per 1° figured every 10°, and figured every 5° with very small, mirror image numbers for use with a bearing device. 360° compass card illumination. Steering repeater compass 360°card: one graduation mark per 5° and figured every 10° 10° card: one graduation mark per 0.5° figured every full degree. Compass card illuminated 60° each side of lubber line. Bulkhead repeater / Console repeater 360° card: one graduation mark per 1° and figured every 10° Compass card illuminated 60° each side of lubber line. All repeater compasses are supplied with a prefabricated connection cable.
1.2.2
Housing, Bulkhead Repeater Compass The bulkhead repeater compass is supplied in a rectangular, galvanized and black enamelled steel housing. Three attachment feet are provided. The housing also mounts a dimmer, a synchronization switch, a ground terminal and a cable gland. The bulkhead repeater compass is watertight to IP64.
1.2.3
Housing, Bearing Repeater Compass The bearing repeaters are produced in a pressed stainless steel housing with a weight in the lower part. Two plastic bushes in the upper part of the housing accept the trunnion journals of the gimbal ring in the bearing stand or bulwark console. The bearing repeater can be attached to the gimbal ring at 000° or 90°. Various bearing devices may used on this bearing repeater.

1.2.4
Console Repeater Compass and Steering Repeater Compass for Console Mounting Format and design of the console repeaters are fully compatible with the C.PLATH "Equipment Family" - a comprehensive range of standardized bridge equipment having front plate dimensions to DIN 43718. The main supportive part is the front plate. The entire compass card is visible through a circular window in the square front plate. A dimmer and a synchronisation switch are located to the right and left below the compass card.
1.2.5
Bearing Stand The bearing stand is manufactured from an electrostatic powder coated aluminium alloy and comprise one single part. A horizontal circular handle is provided at the top of the stand, above which two bearing supports are attached. These accept the gimbal ring in which the bearing repeater is suspended. An aluminium connection box with cable glands, dimmer and a synchronisation switch is attached to the lower half of the stand. Here, the repeater is connected to the gyrocompass system. A watertight cover is provided to protect the stand and the repeater from the effects of the weather.
1.2.6
Bulwark Console The bulwark console is an aluminium construction and is provided with four holes for attachment to a bulwark console. A gimbal ring is attached to two bearing supports. Fixed to the side of the console is a connection box with cable glands, a dimmer and a synchronisation switch. Here, the repeater is junctioned to the gyrocompass system.
1.2.7
Bearing Devices A selection of bearing devices, ranging from the conventional sight model to the telescopic type, is available for bearing repeaters. All bearing devices locate in the bore in the center piece of the top glass and on the verge ring, allowing bearings to be taken in relation to north and the ship's head.
1.2.8
Functional Description The angular information received through the serial interface is processed in an 8 bit microcontroller and passed to the step motor control logic. In order to ensure that the value displayed by the repeater is also the value received, the mechanical position of the compass card is monitored by a photoelectric cell every 10° and at the 000° position. If the mechanical position does not coincide with the computed value, the microcontroller will correct the error. If the values are not within reasonable limits, a failure alarm is actuated. If a repeater is switched off or a power failure occurs, the last angular information is stored in an EEPROM to maintain synchronisation when power is restored. Synchronisation can also be forced by means of a switch. Here, the compass card is brought to the 000° position regardless of the current angular information. When 000° has been found, the compass card returns to the value of the angular information currently received.

Synchronization of Repeater Compasses After switch-on, the repeater compasses synchronize automatically with the master compass. For the duration of this procedure the "Sync." switch will illuminate continuously in red with short breaks. Alternate flashing on and off for equal periods of the "Sync." switch indicates that the repeater in no longer synchronized with the master compass. Press and hold for 5 seconds the "Sync." switch to synchronize the repeater with the master compass. The compass card(s) will turn to the 000° position where it (they) will remain for 2 seconds. The compass card(s) will then return to the heading shown by the master compass. The synchronization procedure is now complete. If the repeater compass cannot be synchronized with the master compass, the repeater will rotate the card(s) clockwise at maximum speed for up to 55 seconds. The repeater will then switch back to master compass operation without having synchronized. The "Sync." switch will flash alternately on and off for equal periods to indicate this fault.

The following points are to be taken into consideration when selecting a location: • the ambient temperature • magnetic clearance • the protection grade refer to the technical data in section 1.3. Ensure that the system is deenergized before connecting repeater compasses. All repeater compasses are supplied with a prefabricated cable which is to be connected in accordance with the system connection diagram as supplied by C.PLATH. 3.4.1
Installation of the Bearing Stand and Bearing Repeater (see fig. 3-03) The bearing stand is to be attached to the deck by means of four M16 bolts. The bearing stand may be positioned amidships, port or starboard. Care is to be taken that the bearing stand is positioned so that the horizon is not unduly obstructed by the superstructure of the vessel when bearings are taken. All dimensions and electrical information is contained in the drawings and diagrams specified in section 3.4. Page 3-07

Prepare the place of location for installation. a) Weld four M16 bolts on their heads to the deck. To ensure the accuracy of the bearing repeater in later use, the bolts must be positioned exactly parallel to the vessel's longitudinal axis. b) Weld a cable inlet pipe 30 x 3 mm to the deck and cut an inlet hole for the cables. c) Lay the connecting cables. Place the bearing stand over the attachment bolts. Fit the washers and screw on the retaining nuts but do not tighten them. Loosen the lock-nut (24 mm AF) securing one of the trunnion journals in the gimbal ring. Screw back the trunnion journal (8 mm key) by approximately 2 cm. CAUTION: The weight of the bearing repeater is 5.1 kg. When required, the following two assembly operations are to be carried out by two persons. Lift the bearing repeater into the gimbal ring so that the lubber line points to the ship's head and locate the fixed trunnion journal in the bush in the repeater. Turn the loosened trunnion journal clockwise into the opposite bush so that the repeater is secured without play in the gimbal ring. Check that the bearing repeater is positioned concentrically with the gimbal ring. When necessary, adjust the trunnion journals to effect concentricity. Tighten the trunnion journal lock-nuts. Fit an azimuth device to one of the bearing repeaters. Place a pin in the hole of the center piece of the opposite bearing repeater compass. Using the azimuth device, take a bearing across the open bridge on the pin in the opposite bearing repeater compass. The bearing taken is to be 90° (or accordingly 270°). NOTE: If it is not possible to take a bearing across the open bridge, carry out steps 13, 14 and 15 instead of steps 11 and 12. Determine the distance between the longitudinal center line of the vessel and the center point of the bearing repeater. Position as far away as practically possible a beam with a perpendicular reference marking, see fig. 3-03. Take a bearing on the perpendicular reference marking through the azimuth device. The bearing taken is to be 360° towards the ship's head or 180° astern. If the bearing taken is not 360° or 180°, turn the bearing stand to obtain these values. Tighten the nuts securing the bearing stand. Unscrew the screws attaching the cover to the connection box and remove the cover. Insert the cables from the bearing repeater and the gyrocompass system through the cable glands into the connection box. Connect both cables to the terminal block in the connection box in accordance with the system connection diagram.

Error Codes Error codes in the form of two digit hexadecimal numbers are shown on a 7-segment display. Since there is only one 7-segment display, the two digits of each code are shown consecutively. When more than one error code is present, the code numbers are displayed in an ascending sequence. Display of digits: 0.5 sec. Interval between digits: 0.1 sec. Interval between error codes: 1.0 sec. The 16 hexadecimal digits are: 0 1 2 3 4 5 6 7 8 9 A b C d E F and allow error codes over a range of 00 to FF. The numbers are displayed reading from left to right. Example: error code 27 (twenty-seven) first the "2" then the "7". Orientation is arranged so that the edge of the PCB is the bottom of the display. An exception is when all dip switches are set to ON or OFF. A display of two digit error codes is no longer shown and a single "0" is displayed ten times when all dip switches are set to ON. When all dip switches are set to OFF, a single "1" is displayed ten times. The numbers are displayed for 0.5 sec. Interval is 0.5 sec. The error codes are divided into three groups: F = Fault W = Warning H = General information Errors and warnings are displayed as long as the cause remains unresolved. General information is normally given when a change in the current operational status occurs or when the positions of the dip switches are changed. The associated code is displayed five times. Example: when the external NMEA bridge is closed, the code "db" is displayed five times. Because in this example the format of the serial interface NMEA 0183 is concerned, the following will also be displayed: "80" = NMEA format on (5 times) "84" = baud rate 4500 (5 times)
During normal operation (i.e. without faults) the following error codes in accordance with the selected interface format will be displayed: C.PLATH format: NMEA 0183: Lehmkuhl:
