Installation Of The Sending Units - VDO Logic Log Depth Montageanleitung Und Bedienungsanleitung

The drilling template has been designed to correctly space the instru-
ments, if other VDO instruments are also installed, and to permit the in-
stallation of the white protection cap.

Installation of the sending units

The senders must be installed in the hull at a turbulence-free location.
The echo sounder especially should be close to the longitudinal ship
axis.
Install the senders at approximately the same height, side by side, or
stagfered one behind the other.I Make sure you have sufficient distance
to spars, stringers, bulkheads, etc.
Avoid locations close to external valves, anodes, log sen-
ders, etc. to prevent mutual influences by turbulence.
Measure and write down the distance between echo soun-
der and keel bottom, and the draught of the ship. These data
will be needed later for the basic settings.
Never combine the echosounder cable with other cables to a
cable harness. Ignition pulses and other disturbances could
impair the echosounder function.
under cable. If necessary, an extension using a shielded, fle-
xible coaxial cable with silver-coated conductor can be used
to increase the length to 20 m.
