2.2 Transducer type
The ST30 Depth system is supplied (as standard) with a plastic through
hull transducer. This is suitable for use with Glass Reinforced Plastic
(GRP), Steel and Aluminium hulls.
Wooden hull and transom mount installations require a different type of
transducer. Please refer to the following table for details.
Caution: Plastic through hull transducers must not be used on vessels
with wooden hulls.

2.3 Installation
All depth transducers are supplied with detailed installation and
maintenance instructions. These instructions, together with the following
notes, should be read thoroughly before attempting to install the
transducer.
10° Max
D630
1. The ST30 Depth transducer must be within 10° of the vertical,
forward, aft and athwart ships and within the shaded clear flow areas
as shown.
D587

Chapter 2: Transducer Installation

2. Run the transducer cable back to the instrument. Avoid fluorescent
lights, engines, radio transmitting equipment and the speed
transducer cable. The transducer cable should also be kept clear of
bilge's, where possible, and be secured at regular intervals.
Note: The transducer cable must not be shortened. Shortening
of this cable will affect the performance of the unit. For further
information, please contact Autohelm or an authorised agent.
If the bronze through hull (Z118), in hull puck (Z117) or retractable depth
(Z120) transducers are to be used, the following modification must be
carried out to the transducer lead.
1. Using a pair of wire cutters, remove the moulded plug from the end
of cable.
2. Strip the outer cable back 38mm (1.5in).
3. Using a pair of cable strippers, remove 10mm (3/8in) of insulation
from each wire.
4. Using a suitable crimping tool, attach a 1/8in spade connector
(supplied) to each of the wires.
5. Connect the wires to the instrument in accordance with the following
table.

Chapter 3: Fault Finding
All Autohelm products are, prior to packing and shipping, subject to
comprehensive test and quality assurance programmes. However, if a
fault arises with the ST30 Depth, the following table will help to identify the
probable cause and provide the most likely cure.
Note: After installation, poor performance may be experienced if the
surface of the depth transducer has not been 'wetted'. Wetting can take
up to 24 hours under normal conditions. The transducer can be 'wetted'
prior to launch by applying a mild detergent to the external face.

4.1 Instrument
Atmosphericconditions may cause condensationtoappear on the
instrumentwindow. This will not harm theinstrumentandcan be cleared
byincreasingtheillumination setting to level 3.
Chemical andabrasive materials must not beusedtocleanthe
ST30Depth instrument; if the instrument isdirty,cleanwith a soft, damp
cloth.
4.2 Transducer
Referto the Installation and Maintenance instructionssuppliedwiththe
transducer.
4.3 Cabling
Examineallcablesforchafing or damage to the outer shield and, where
necessary,replace andre-secure.
