Connecting the transducer cables to the Transceiver Unit
The transducer cables are connected to the Transceiver Unit using a large transceiver
plug. The transceiver plug must be firmly connected to the side socket on the Transceiver
Unit - and the transducer must be submerged in water - before you can transmitting
(‘pinging’) with the SC90.
Prerequisites
We assume that you are equipped with a standard set of tools.
This tool set must comprise the normal tools for electronic and
electromechanical tasks. Each tool must be provided in various
sizes. We recommend that all tools are demagnetized to protect
your equipment.
Context
Once the transceiver plug is connected to the Transceiver Unit,
and the transducer is submerged in water, the SC90 can be set
to transmit ("ping").
Caution
You must never start SC90 transmissions ("pinging") when
the ship is in dry dock. The transducer may be damaged if it
transmits in open air.
Procedure
1 Make sure that the plug housing is clean and not damaged
in any way.
2 Make sure that the gasket is clean and not damaged in
any way.
3 Mount the transceiver plug.
a Hold the plug housing on top of the socket.
b Push the plug gently in place.
To avoid unnecessary strain on the connectors, you must insert the transceiver
plug straight in.
c Insert the bolts carefully, and make sure that they fit to the threads.
Use the bolts and washers provided for the protecting cover.
