Introduction
ST30 Speed Operation and Installation Handbook
Designed for above or below deck installation, the ST30 Speed can be
used as a stand-alone master instrument or can be set to repeat speed
information from the SeaTalk bus.
The ST30 Speed will display the following information:
• Boat speed
• Log
• Trip
• Maximum speed
• Average speed
• Illumination level

The ST30 Speed 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. For this reason the instrument must be mounted where
the back cover is protected from direct water.
The rear 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 two fixing
holes 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 of the instrument (1).
7. Install the instrument (1) in the chosen location and secure with the
thumb nuts (3) provided.

on the rear of the instrument and 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.

1.5 Connection to adjacent ST30 instruments
The ST30 Speed 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.

2.2 Transducer type
The ST30 Speed 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 at speeds up to 32 knots.
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 vessel's
with wooden hulls.
Note:
designed for speed up to 32 knots. For vessel's that will exceed this
speed, please refer to section 2.3 which contains instructions on how to
fit the high speed paddlewheel (supplied).

2.3 Paddlewheel replacement
If the high speed paddlewheel (supplied) is to be fitted, or the existing
paddlewheel to be replaced, proceed as follows:
1. Remove the retaining rings (1) and pin (6) from the speed
transducer (3).
2. Withdraw the speed transducer (3) from the through hull fitting (4).
3. If replacing a worn paddlewheel and if the vessel is still in the water,
replace the speed transducer (3) with the plug (5).
4. Remove the pin (6) that retains the paddlewheel (7) in the speed
transducer (3). This is a simple press fit into the transducer housing.
Page 14
Chapter 2: Transducer Installation
5. Fit the high speed/replacement paddlewheel (7) to the speed
transducer (3) and retain with the pin (6).
Note:
surfaces of each paddle are facing forwards.
6. Assemble the speed transducer (3) to the through hull fitting (4) and
secure with retaining rings (1) and pin (2).

2.4 Installation
Speed transducer (through hull)
ST30 Speed Operation and Installation Handbook
All speed 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.
For accurate speed readings, locate the speed transducer in the shaded
'clear flow' areas as shown.
D587
The transducer should also be:
• ahead of propellers (10% W.L. length minimum)
• at least 150mm (6in) from the keel (with sailing yachts siting should be
forward of the keel).
• near the centreline of the vessel
• clear of other through hull fittings or projections
• have sufficient clearance inside the hull to allow the nut to be fitted
• have 100mm (4in) clearance above the through hull fitting for withdrawal
Page 16
Chapter 2: Transducer Installation
2.5 Cabling
Run the transducer cable back to the instrument. Avoid fluorescent lights,
engines and radio transmitting equipment. The transducer cable should
also be kept clear of bilge's, where possible, and be secured at regular
intervals.
Note:
The transducer cable can, if required, be shortened. However, new
1/8in spade connectors must be crimped to the shortened cable.
If the bronze through hull (Z116) or the transom mount (Z119) transduc-
ers are to be used, the following modification must be carried out on 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 4: Maintenance
4.1 Instrument
Certain 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
Speed 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.
