Chapter 1 Installation
1.3 Installation of transducer
The installation method of transducer is mainly two methods, ship's side installation and
bottom hull installation. The installation method differs depending on the type of boat (steel,
wooden and FRP). The quality of the transducer installation method affects the performance
of the echo sounder. Therefore, ask a technical dealer to install the transducer.
1.3.1
Cautions on installation of transducer
1. Not affected by air bubbles
If the transducer is installed incorrectly, air bubbles may adhere to the radiation surface of
the transducer when the ship sails, making it impossible to receive ultrasonic wave. To
exclude the influence of air bubbles, it is effective to increase the protruding of the
transducer from the bottom of the ship. It is also effective to move the installed position of
transducer away from the keel line.
2. Not receive noise from screws
Noise may be displayed on the screen when the screw speed is increased. In this case,
replace the screw or install the transducer away from the screw.
3. Not receive noise from the engine
If the echo sounder receives noise from the engine, move the installed position of
transducer away from the engine.
Cautions on installation XID-adaptive TD
Broadband transducer (TDM-052A/TDM-062A/TDM-083/TDM-091/TDM-091D/TDM-071) and Dual
frequency transducer (TDM-031D/TDM-041/TDM-041D) are XID-adaptive TD
Pay attention to the following when installing XID-adaptive TD.
-Transducer MUST be installed in pocket, external tank only.
Active face of transducer must be immersed in seawater to cool the transducer unit.
-DO NOT cover with FRP. DO NOT install inside a yellow tank.
The transducer may overheat, leading to failure.
-DO NOT install in the engine compartment or other hot place.
The transducer may fail if the temperature of the sea water in the external tank becomes high.
-Always operate the transducer in water.
Operating in air will allow the transducer to overheat resulting in failure.
The CVS-872D monitors the internal temperature of the transducer to protect it from failure due to
overheating. When XID-adaptive TD
that the transducer does not become hot by monitoring the internal temperature of the data received
from the transducer.
Caution:
may temporarily reduce the sensitivity of the image. For safe use, consult your dealer if
temperature control is activated frequently.
