Page 7: The Vdo Depth Sounder
Analog scale Display Pushbutton The VDO depth sounder is an advanced depth measuring instrument designed for sport navigation. The pointer indicates the water depth below the keel in meters or feet on an analog scale when the system is active. This value is also shown as a digital value by the display in the lower dial section. -

BASIC CALIBRATION / ALARM cally. The unit now displays the water depth below keel (4.6 m in the ex- ample). Setting and activating the shallow water alarm In unsafe depths and in waters with unknown depths the alarm will warn you in time to avoid shallows and to prevent boat damages. - Page 12 ALARM The acoustic alarm can be switched off by pressing the button. It stops automatically when the depth below keel is greater than the set thres- hold. The alarm function is deactivated if the button is quickly pushed twice when the current depth (2.7 m in the example) is displayed. Push button Push button...

Page 13: Troubleshooting
TROUBLESHOOTING Troubleshooting Fault: Cause and correction: - No depth sounder function - Check electrical connections per wiring diagram. - Check supply voltage, 10.8 ... 32 VDC. - Check fuses in fuse box. - Wrong indication - Check display unit selection. -
Page 14: Maintenance Of The Vdo Depth Sounder
TROUBLESHOOTING / MAINTENANCE - Neighbouring ships also operating a depth sounder, for instance in a marina. - The speed of the boat can also influence the measurement. These examples show that even an optimum installation cannot elimina- te all causes for temporary disturbances. - Page 15 INSTALLATION Thread the indicating instrument cables from behind the mounting hole through the housing mounting nut. Place the supplied black rubber ring on the instrument back. Make the electrical connections of the indicating unit per cir- cuit schematically (see „Electrical installation“) and insert the instrument into the installation hole.

Page 16: Installation Of The Depth Sounder
INSTALLATION Installation of the Depth Sounder The echo sounder unit must be installed in a turbulence-free zone in the hull. It should be mounted vertically. Do not install the sending unit close to external valves, anodes, log sending units, etc. to avoid influences by tur- bulence. -
Page 17: For Internal Installation
INSTALLATION Installation on powerboats: First Stringer Depth sending unit Installation of the echo sounder: internal installation An internal installation of the echo sounder is only possible on ships with a fiberglass reinforced hull. This does not apply to fiberglass sandwich hulls. - Page 18 INSTALLATION The echo sounder can be definitely fixed when you have found the opti- mum location. Install the echo sounder by bonding it with a salt-water resistant sealant. Install the echo sounder: Sealant Fixation by sealant: Avoid air bubbles between echo sounder and hull.

Page 19: For Through-Hull Installation
INSTALLATION Installation of the echo sounder: through-hull installation Make a hole, 53 mm diameter, at the selected location. The hull thick- ness should not exceed 36 mm. Camber the hole out at 45 degrees for good sealant distribution and to obtain a reliable seal. - Page 20 INSTALLATION Insert the echo sounder into the hull sleeve and align the hole in the upper sounder section with the holes in the sleeve. Secure the sounder by inserting the retainer pin through the holes. Lock the retainer pin by installing the rings at both pin ends. Tie the control rope of the blind plug to one of the retainer pin rings.

INSTALLATION Connection of a repeater Make the power supply con- nection for the repeater the same as the main unit (see page 44). The connection bet- ween the main and the repea- ter, including the alarm buzzer, is shown in the diagram below. Main-unit Repeater Note that the unit, keel depth... -
Page 23: Circuit Diagram Legend
INSTALLATION Advice on the connection of the alarm buzzer: If the alarm is triggered by the main-unit, the alarm buzzer will send a permanent sound. If the alarm is triggered by the repeater, the alarm buzzer will send an in- termittent sound. -
