Introduction
ST30 Depth Operation and Installation Handbook
Designed for above or below deck installation, the ST30 Depth can be
used as a stand-alone master instrument or be set up to repeat
information from the SeaTalk bus.
The ST30 Depth will display the following information:
• Water depth
• Shallow alarm
• Deep alarm
• Keel/Waterline offset
• Minimum depth
• Illumination level

1.1 Siting
Autohelm
The ST30 Depth instrument may be installed above or below deck where it
is:
• easily readable by the helmsman (normally viewed at eye level)
• protected from physical damage
• at least 230mm (9in) from a compass
• at least 500mm (20in) from radio receiving equipment
• accessible from behind for ease of installation and cable running
Note:
To prevent the build-up of moisture the instrument breathes through
the back cover. The instrument must, therefore, be mounted where the
back cover is protected from direct water.
The case is fitted with a foam gasket to form a water tight seal between
the instrument and the installation face.

1. Make sure the surface to which the instrument (1) is to be mounted is
smooth and flat.
2. Use the template (supplied) to mark the centres for the fixing studs (2)
and the instrument connector boss.
Note:
To allow protective covers to be fitted, adjacent instruments
should be sited not less than 6mm (0.24in) from each other (116mm
centre to centre min.).
3. Drill two 5mm (0.2in) diameter holes for the fixing studs (2).
4. Using a 60mm (2 3/8in) diameter cutter, drill a location hole for the
instrument connector boss.
5. Connect the power supply and transducer cables to the back of the
instrument (1). (See relevant installation sections)
6. Screw the two fixing studs (2) into the back cover of the instrument
(1).
7. Install the instrument (1) and secure with the thumb nuts (3) provided.

–
For stand-alone operation, use the 1m cable supplied with the instrument.
1. Connect the moulded power plug to either SeaTalk connection on the
rear of the instrument. Run the free end back to the vesselÕs
distribution panel.
2. Cut the power cable to length and connect the red wire to the positive
12V terminal and the screen to 0V. Protect with a 5A circuit breaker
or fuse.
1.4 Power supply (SeaTalk system)
If the ST30 Depth is to be connected to a SeaTalk system, use a Standard
SeaTalk Extension or Interface cable.

1.5 Connection to adjacent ST30 instruments
The ST30 Depth is supplied with a daisy-chain cable that allows adjacent
ST30 instruments to be linked together. The daisy-chain cable supplies
power to adjacent instruments and allows data to be transmitted and
received via the SeaTalk bus.
The daisy-chain cable plugs into one of the SeaTalk ports on the back
cover. Incorrect orientation is not possible as the ports and plugs are
matched.

Chapter 2: Transducer Installation
2.1 Connection to instrument
The ST30 Depth transducer is supplied with 10m (32.5ft) of cable. This
cable plugs directly into the back of the instrument.

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.

2.3 Installation
ST30 Depth Operation and Installation Handbook
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.
Chapter 4: Maintenance
Chapter 4: Maintenance
4.1 Instrument
Atmospheric conditions may cause condensation to appear on the
instrument window. This will not harm the instrument and can be cleared
by increasing the illumination setting to level 3.
Chemical and abrasive materials must not be used to clean the
ST30 Depth instrument; if the instrument is dirty, clean with a soft, damp
cloth.
4.2 Transducer
Refer to the Installation and Maintenance instructions supplied with the
transducer.
4.3 Cabling
Examine all cables for chafing or damage to the outer shield and, where
necessary, replace and re-secure.
4.4 Advice

For advice, or further information regarding installation of this product,
please contact the Autohelm Product Support Department or your own
National Distributor.

Chapter 5: Operation
The ST30 Depth leaves the factory set to:
• display depth in feet
• with the deep and shallow alarms switched off
• in master mode
These settings can be changed in calibration (see section 6.1).
When the ST30 Depth is switched on, the instrument will display current
water depth in the units set up in calibration.

Note:
When the ST30 Depth is used in a SeaTalk system, illumination may
be adjusted from any instrument.
The ST30 Depth is equipped with visual and audible shallow and deep
water alarms.
Both of these alarms are set in calibration (see section 6.3).
Any button press will silence the 'Shallow' alarm. However, the 'Shallow'
indicator will continue to flash until the depth exceeds the alarm value.
The 'Deep' alarm sounds when the 'Deep' setting is crossed either when
going from shallow to deep or deep to shallow waters. Any button press
will silence the alarm.
The 'feet or metres' legend flashes whenever the depth signal is lost.
