Installing the Transceiver Unit
The Transceiver Unit is normally positioned close to the Hull Unit in the sonar room. The
transceiver can also be installed in a dedicated compartment. The physical distance between
the Transceiver Unit and the Hull Unit is restricted by the length of the transducer cables.
Prerequisites
You must be equipped with a standard set of tools. This tool set must comprise the normal
tools for electronic and electromechanical tasks. This includes different screwdriver types,
pliers, spanners, a cable stripper, a soldering iron, etc. Each tool must be provided in various
sizes. We recommend that all tools are demagnetized to protect your equipment. Depending
on the chosen installation method, additional tools may be required. Observe the relevant
rules and regulations related to welding. The quality of the welding is critical to the safety of
the vessel. Welding must only be done by a certified welder.
Note
If required, all documents provided by the shipyard for the physical installation of the
MF90 system must be approved by the vessel's national registry and corresponding
maritime authority and/or classification society. Such approval must be obtained before the
installation can begin. The shipowner and shipyard doing the installation are responsible
for obtaining and paying for such approval.
Context
Free bulkhead space is required.
Observe the limitations due to the cable lengths. The physical distance between the
Transceiver Unit and the Hull Unit is restricted by the length of the transducer cables.
Remember to take into consideration the slack necessary to lower and hoist the transducer.
