9.4 Starting up the Hull Unit
Introduction
Observe the following procedure to start up the Hull Unit. To
ensure correct performance, tick off every item when the action has
been carried out.
WARNING Before starting up the sonar equipment on a
recently launched vessel, make sure the depth
under the keel is sufficient for the transducer to
be lowered safely.
When starting up the equipment on board a
vessel in dry dock, check first under the vessel
and inside the sonar room. Personnel, tools and
other potential obstructions must be kept clear
of the transducer and related lowering and
hoisting machinery to avoid personal injury or
damage to the equipment.
Functional check
Before you start the functional check, make sure that the mains
fuses for the hull unit has been disconnected in the fuse box. This
check will only require the +24 Vdc standby power from the
Transceiver Unit.
1 Use a spanner to open the door on the Motor Control Unit.
- The unit is mounted on the Hull Unit.
2 Press the red button marked 0 on the motor overload switch
S301 in the Motor Control Unit.

5 Locate the hand crank inside the Motor Control Unit, and
mount the hand crank onto the stub shaft through the hole in
the top cover.
6 Turn the hand crank counter-clockwise to lower the
transducer manually approximately 10 cm (4”).
