>ILPHMR«N Marine The Alphatron Marine AlphaLine instrument range was designed for navigation and control of ships and is based on generic hardware and software, allowing for many different applications. • Thoroughly read this instruction manual before installation and operation of the equipment. • We recommend to keep this manual nearby the equipment to ensure ready access to it.

>ILPHMR«NMarine Reverse polarity protection Abbreviations as used in this manual are explained in Table 2: Abbreviations on page 5.

>ILPHMR«N Marine The AlphaTurn complies with the applicable standards, norms and regulations:

II Safety Information II.1 Pictorial Indication • Indicates a hazardous situation which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations. Indicates a hazardous situation which, if not avoided, could result in death or serious injury. Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury. Indicates information considered important but not related to injury. It is typically used to prevent damage to equipment or property. Do not disassemble or modify the equipment. Failure to observe...

The equipment can be damaged. • If the instruments are not stored as described, it will void the warranty. • When cleaning the surface, do not use any organic solvent such as thinner or benzine. Otherwise, the paint...

III Introduction Each type in this navigation and control instrument product range consists of a display unit and, if applicable, one or more external remote I/O modules. The following display size is available for your AlphaLine instrument: AlphaLine MFM The AlphaTurn is an MED Type Approved system for showing the rate of turn (ROT) on a standard ship's compass.

>ILPHMR«N Marine Installation follows a generic method and is applicable to the complete range of AlphaLine instruments. This chapter describes the installation into a console. • This product must be installed in accordance with the installation methods described in this manual. Acting otherwise will void the warranty. The Location Class/Category of the AlphaLine instrument is: EXPOSED (may be used outside), but only if installed with the optional sealing kit and according the installation instructions as mentioned in Mounting Instrument on page 10. 1.1.1 Supplied Parts The AlphaTurn is...

>1LPHMR«NMarine 1.1.4 Fitting Instrument Mounting Frame Prior to fitting the display unit, install the mounting frame. 1. Make a square hole in the (overhead) console. Use the provided template. For dimensions, see Mechanical Drawing MFM on page 50. 2. Push the mounting frame into the hole and attach it with four screws. 3. Push the display unit into the mounting frame. Note The instrument is locked into position by a spring system. Note Use the Overhead Mounting Kit for securing the display unit to an overhead console, to prevent the unit from falling out. 1.1.5 Fitting Instrument Water...

>ILPHMR«NMarine Mounting instructions: 3. Remove the 4 clips ( ) from the bracket. 4. Apply the gasket to the instrument. INFO: Pay special attention to the small protruding cam, so that it fits exactly in the gap in the front panel. 5. Place the instrument in the bracket. 6. Mount the 4 lock washers and hex nuts. 1.1.6 Instrument Electric Connections All AlphaLine instrument versions share the same electronics with identical connections. For pin-outs, see Table 4: Serial Connector P12 (8 pins) on page 17 and Table 5: Serial Connector P19 (12 pins) on page 17. 1.1.7 Cable Use the following...

Table 3: Connection Cables 1.1.8 Cable Preparation Cable preparation and cable connections as described in this manual are essential for the correct functioning of the = Note There are two type of cable sides (connections): sending cable sides and receiving cable sides. Normally, the cable shield will be grounded only at the sending side of the cable. For a power cable, this is the power supply side. For a data cable, this is the Tx side of the cable. For combined Tx/Rx cables, either side can be grounded, but beware of grounding only one side. 1.1.8.1 Cable Preparation Sending Sides 1....

1.1.8.2 Cable Preparation Receiving Sides 1. Remove approx. 80 mm of the plastic cable sheath, including the grounding shield. 2. Wrap insulating tape over the cable end. 3. Attach the isolated cable end to the metal saddle on the rear of the instrument. See Figure 5: Cable Preparation Receiving Cable Sides on page 14. Figure 5: Cable Preparation Receiving Cable Sides Note Always check the drawing for the correct shielding of signals. 1.1.9 Grounding Instrument To function properly, the AlphaLine instrument must be grounded to the ship’s mass. For this purpose the instrument has a grounding...

1.1.11 Serial Interfaces This chapter provides extra information about the serial interfaces used in the Marine Electronics. • IEC 61162-1 This standard is the most commonly used. In the standard, the sender (Tx side) and receiver (Rx side) are referred to as talker and listener. It has the following characteristics: • Communication speed: baud rate of 4800, 8 databits, 1 stop bit, no parity. One talker (Tx side, commonly a sensor such as GPS) may be connected to one or more listeners (Rx side, e.g. displays or computer systems such as ECDIS). The circuit looks as shown in Figure 7: IEC...

Figure 8: IEC 61162-2 Circuits The main difference with the IEC 61162-1 standard is that a COMMON signal is added here for a good reference to isolated ground. • The shield of the cable is connected to the earth on the transmitting side, and is NOT connected on the listener. Note In case the NMEA signal is connected both ways, two cables should be used with proper shielding as described above. (It is just above situation times two for the opposite direction). Only one talker is connected to the bus, and multiple listeners may be connected to the same bus without the need for a signal...
