CHAPTER 1: GETTING STARTED
Overview dl2
The DL2 dual axis Doppler speed log is a Navigational Doppler Speed log system that measures
speed in two axis (longitudinal and transversal) through the water and over the sea bed. The system
requires no external inputs, however adding inputs from other navigational systems enhances the
functionality and allows comprehensive quality control of the data.
The system fullls all class and type regulations based on MED B (wheelmark) and is manufactured
in Norway under stringent production controls.
The system comprises of 5 units;
1. The Operator unit – CU-M001-SA
The system is to be tted with a touch
display panel where full setup and
operation can be performed.
2. The electronic unit – JB70D2-SA
This unit comprises of a processor
and a power supply. It is a compact
single euro cabinet. It enables the
user to interface to both modern and
older navigation systems with all the
expected connectivity. The unit has a
built-in web server, allowing the system
to be fully integrated into existing
navigation systems (extra approvals
may apply).
3. Junction box JB12-SA. To connect
sensor cable to yard supplied extension
cable.
4. The sensor – The sensor (DL2SG-
SA) contains acoustic elements and
a fully programmable transceiver unit,
allowing the system to adapt itself
to the conditions and requirements.
In addition the sensor contains a
temperature sensor and tilt sensors.
5. Sea valve. The sensor may be installed
into a sea valve for single bottom hull
(SB-100-XX) or sea valve for double
bottom hull (DB-100-XX).

placemenT Of The OperaTOr uniT
The operator unit is placed on the bridge.
Some standards require some operations of
the unit to be available from ‘standing position’.
These operations are available from the operator
unit and multi-repeaters if both input and output
are connected.
Dimensional drawings are found in Appendix 1.

supplied extension cable (See chapter 3).
It is placed in a dry place within reach of the 40m sensor cable.

Installation DL2 Doppler Speed Log System
placemenT Of The sea valve
Mounting instructions for the sea valve is available from the SKIPPER web site in separate manual
depending on the chosen type. When placing the speed log sensor, consider the following moments:
• Free sight to the bottom (it should be possible to draw a cone of +-45 degrees from the
sensor to the bottom).
• The active face of speed sensor must be in parallel to the horizontal line, max offset +-1°.
• Do not mount transducers aft of bow thruster, propeller outlets or aft of other hull
installations (such as outlets, vents or other protruding details) that may create aeration or
turbulence.
• It is necessary to select a part of the hull that is submerged and free from turbulence and
aeration under all load and speed conditions, and to avoid positions where air is trapped in
heavy weather.
• If a at, horizontal section is not available for transducer tting, the shipyard must construct
a suitable bed. Welding seams in this area and forward should be smoothed and rounded
off in order not to create turbulence or aeration and maintain a laminar waterow at all
speed ranges of the vessel.
• Select an area that is acoustically quiet. The system operates at frequencies between 270
kHz and 284 kHz.
There are 2 channels in DL2.
The acoustic signal is sent in
a 30deg angle in forward and starboard
directions.
In addition a tilt sensor is used to
compensate for vessel movement.

Installation DL2 Doppler Speed Log System
The generally best placement on larger vessels is in the front region of the vessel just behind the
bulbous bow (see g above). This area is generally designed such that the bubbles are pushed to
either side of the bulb, leaving a clear area under the bulb and just behind. The sensor is installed in
a sea valve in order to service the sensor (clean or replace) without docking the vessel.
It is recommended (but not required) to install the sea valve in a dry area, like a bow thruster room.
This will enable easy cable access to junction box and additionally increase the lifetime of the sea
valve.
The sensor DL2 is installed into sea valve
100mm for single bottom SB-100-SB or
double bottom DB-100-SB.
Please see sea valve manual for installation
procedure.
Manuals available as downloads from
www.skipper.no
The sensor includes 40m moulded in cable.
The cable is 11 mm in outer diameter with a
bending radius of 56 mm. The cable can be
cut or extended if required
placemenT Of The sensOr in sea valve
NOTE
During physical installation of sensor into sea valve please make special care of the following points:
• Sensor to be lowered completly into bottom ange making sensor head ush with outer hull.
• Sensor forward direction to be aligned +/-10deg. (Fine adjust by software in calibration page)
• Clamping unit nuts and nut M50 to be tighten to secure sensor position.

CHAPTER 3: WIRING
The JB70D2-SA does not contain a physical switch (only software) and should be connected to a
circuit breaker for removal of power.
Power may be nominal 24V DC (No more than 32V DC) and/or 115-220V AC. Max 60W typical 15W.
The AC input is an optional back up for JB70D2-SA only. The operator unit CU-M001-SA requires a
24V DC power supply.
There are no input fuse on the CU-M001-SA or JB70D2-SA.
The power input should be including a fuse rated for 100% - 200% of max power installed components.
Example: A 24V DC to power both CU-M001-SA and JB70D2-SA should have a 3A slow blow fuse.
clamping The cables
Cables should be connected to WAGO connector, leaving
approximately 3 cm of tail. They should be stripped with 6-7 mm of
metal showing and these should be connected as in the diagram
above. A small screwdriver with blade size approx 3.5 mm can be
used. WAGO part no 210-719 is ideal for this use.
Outer shields should be collected and grounded in a ground stud on
the edge of the cabinet. The outer insulation should be cable tied to
the plastic handle of the connector, and securely anchored nearby.
The plugs when retted, must be installed such that their clips are
fully in the up position.
