GENERAL FUNDAMENTAL SAFETY INSTRUCTIONS General remark to hydroacoustic equipment LAZ 5100 Even with a carefully selected transducer position and proper installation, the function of hydroacoustic equipment can be impaired by turbulence, acoustic noise or aerated water. As main causes, the following can be stated: −...
Page 12
Work on the system must only be carried out by a qualified technician or a specially trained person working under the supervision of such a technician. Electrical engineering regulations must be observed at all times. Observe all safety instructions and warnings for operating and maintenance attached to the system.
GENERAL INSTALLATION INSTRUCTION FOR ECHOSOUNDERS TRANSDUCER INSTALLATION The performance of an echosounder is limited by the acoustical propagation of sound in water. Mainly this is influenced by the transducer mounting place, the operational frequency and the transducer efficiency. The transducer mounting place is to select in such a way, that the transducer surface is free of air bubbles and turbulence.

2.1.2 CABLING, CABLE LOCATION, CABLE SPECIFICATION Critical point in cabling is the correct handling of the cable screens, especially for the transducer cable. The cable screens have to be grounded only at one point: at the echosounder. In all connection boxes the screens are slide and not connected to ground. Dismantling has to be as short as possible.
2.1.5 INSTALLATION REPORT; SERVICE REQUEST After the installation and the quick check ( see chapter 5.1.2) are completed, please fill in the installation report and send a copy to the ELAC Nautik service center ( FAX +49 431 883 366 ). The original belongs into the technical handbook.

TECHNICAL DESCRIPTION GENERAL The LAZ 5100 Navigation Echosounder is a compact, processor controlled, state of the art system. Presentation of the water depth is made on a Liquid Crystal COLOR Display (LCD) as. • depth below the keel (DBK) Logically structured MENUS assist the user when selecting the operating parameters required. Built to the highest standards, it is certified to meet all requirements laid down by the IMO Resolution MSC 74/69: Amendments to Resolution A.224,Annex 4 .
SYSTEM CONFIGURATION NOTE: See also Figure 3-2, System Configuration with Options. The basic system configuration is as follows: • 1 x Display and Control Unit LAZ 5100 • 1 x Connection Box • 1 x Transducer 3.2.1 DISPLAY AND CONTROL UNIT The Display and Control Unit will normally be installed on the bridge, either mounted in a console or bracket mounted to the deckhead or bulkhead.
3.2.2 TRANSDUCER CONNECTION BOX This will usually be installed near the transducer, to allow a defective transducer to be replaced without having to replace the complete cabling to the Display and Control Unit. The connection box must be made of metallic material. 3.2.3 TRANSDUCER The transducer converts electrical energy to sound energy and transmits this towards the sea bed.
3.3.1 DIGITAL SLAVE DISPLAY(S) These are used to repeat water depth information at other parts of the ship where such information is needed. A total of two Digital Slave Displays can be connected directly to the system. NOTE: Echosounding Systems and remote indicators which detect and display the water depth from a single momentary value per transmission pulse, e.g.
3.3.4 TRANSDUCER OPTIONS If a 2 channel module is installed, the system is capable of accommodating two transducers without further modification, e.g. one fore and one aft, one port and one starboard. Information received from either or both transducer(s) can be called up for display. 3.3.5 SWITCH BOX If no 2 channel module is installed, a switch box can be used for the connection of two transducers...

DISPLAY AREA 4.3.1 SINGLE CHANNEL DISPLAY The Display Area is used to present the user with all relevant information. The screen is divided into two areas. The lower, main area is used to present an echogram of the scenario beneath the ship.
Page 39
REPLAY : When the user chooses to display information stored over the previous 24 operating hours (using the LOG DATA MENU), the word "REPLAY" will appear here. The large window at the right-hand side of the information area is used to display the actual water depth, the measurement mode, units of measurement.
4.3.2 2 CHANNEL DISPLAY In the 2 channel mode information of the transducer location and frequency of the transducer in use is added. If the presentation channel 1/2 is selected, Information of both channels are shown in a vertical split display. The indication NAV OFF is activated without flashing to indicate, that all parameters are mode of presentation is non standard.
4.3.3 WARNING FIELDS Three warning fields are provided on the display: • NAV OFF flashing indicates that one or more parameters do not correspond to the navigational mode, i.e. the user has selected other units, sound velocity or depth mode. •...
ALTERING SYSTEM PARAMETERS AND SETTINGS When the system is switched OFF, parameters selected are stored in the system's memory. When the system is switched ON again, these parameters will be retrieved and used (see NOTE below). NOTE: The "DIM" setting is not stored, a pre-set default setting is used when the system is switched ON.
Page 43
RANGE: The RANGE can be set to suit the circumstances e.g. if a water depth of 35 m is indicated, the 50m range will give a better resolution and accuracy than the 200 m range. The range can be altered in the same way as the gain, except that here, pressing the RANGE key will decrease the range and pressing the RANGE key will increase the range.
